Gliding operations on a 12 degree sloped runway in Papua New Guinea

Well, that is it! The first glider just arrived at the Fane Parish airport in Papua New Guinea

Before it is officially offered as a tourist attraction for the region, some attempts at taking-off and landing must be done. The first trial attracts a few people!

A radical way of dealing with crosswinds in flight simulation.

There is no aircraft in the sky around the Port Moresby Jacksons (AYPY) virtual airport today. No aircraft in the sky but one, a medevac flight.

Arrival of the Medevac towards the Port Moresby Jacksons (AYPY) airport. The winds forbid a normal landing.
Arrival of the Medevac towards the Port Moresby Jacksons (AYPY) airport. The winds forbid a normal landing.

The winds blow from 240 degree at 50G60 kts and the runways are oriented 14/32. It is way above the maximum crosswind authorized for any aircraft.

But the Shrike Commander’s crew cannot wait until the wind calms down. They must land in the next few minutes in order to save a patient’s life.

It is safer to arrive facing the wind and immediately enter the hangar, straight ahead. No taxiing with a 60 knots crosswind.

Useless to say, ATC has already refused the request. But the pilot is the only one who decides of the best landing surface, for the safety of the passengers and himself. He proceeds with the approach after having clearly indicated which path will be followed.

The main problem for the approach is the low level mechanical turbulence caused by the gusty 60 kts winds.

If ATC wants to file a complaint, now is a good time to take a picture of the aircraft and its registration to support the case.

As the aircraft touches the ground, it stops almost immediately. It is necessary to apply power to reach the hangar, as you can see with the white trail on the ground behind the aircraft.

In real life, the touch-down would have had to be as soon as the asphalt start since the presence of the hangar lowers the wind speed a bit.

The Shrike Commander lands a few feet before the hangar. Additional power is mandatory to reach the hangar.

I know, Sumburgh is not an airport meant to receive the Antonov 225, even less with the Russian space shuttle Buran as cargo. In fact, this aircraft and Sumburgh exclude each other mutually. But if you want to try an  almost impossible virtual flight , now is the opportunity.

You must forget about the weight of the aircraft on the runway, the limited space to taxy and park, and the required distance for an eventual take-off. It is probable that once in Sumburgh, this aircraft will stay there forever.

It is interesting, though, to remember the exceptional performances of the Antonov 225. While flying over the Bourget for a demonstration, it was able to maintain a 45 degree turn with the 62 tons Russian shuttle mounted on top.

The approach can be made at a surprisingly slow speed for an aircraft of that weight and the breaking performance is known to be excellent. In Sumburgh, you have the choice between two runways (4700 to 4900 feet). Forget about a safe final approach, you must fly it like a daredevil. It is possible to download the Antonov 225 and the shuttle for free. As for the Sumburgh airport, it is a creation of ORBX and is available for a very reasonable fee.

Losing four engines on a C-130 Hercules in flight simulation

A virtual C-130 belonging to the Blue Angels is taxiing at the High River airport, in Alberta.
A virtual C-130 belonging to the Blue Angels is taxiing at the High River airport, in Alberta.

Wanting to add an almost impossible flight in the “unhinged virtual flights” section of my web site, I tried a flight with the Blue Angels C-130 Hercules (Captain Sim) where the aircraft gradually lost all of its engines.

I am aware that the Blue Angels mechanics are real professionals, so I assumed that the engine failures were caused by an unknown reason.

The take-off was made without problem from the Canadian High River (CEN4) airport. This free airport was designed by Vlad Maly and is available through ORBX. The aircraft leaves the 4150 feet runway heading to the Coeur d’Alène airport (KCOE) in United States.

Eventually, the first engine stops. This does not cause a problem. The propeller is feathered and the gradual climbing continues.

The third engines gives way. A slow descent starts. Bonners Ferry is not very far. The airport is at an altitude of 2337 ft asl.

The aircraft is volontarily flown at a higher altitude than what would normally be requested for a normal approach, just in case the fourth engine stops. When three engines stop after the same refueling, the pilot has the right to think that what feeds the fourth engine can also cause problems.

The fourth engine stops. The flaps will not be functional for the landing.

From now on, the pilot should save the virtual flight a few times since it is possible that several trials will be necessary to glide sucessfully to the airport. This is the fun of virtual flight.

The four engines have now failed on that virtual C-130 aircraft.
The four engines have now failed on that virtual C-130 aircraft.

The C-130 Hercules has become a big glider. When the speed is maintained, the aircraft loses more 1000 feet per minute. It is easier to feel the aircraft’s inertia.

The wheels will be brought out only when necessary since the gear adds a lot of drag.

From the position indicated in the picture below, it is impossible to arrive to the airport in a straight line: the aircraft will glide over the airport. In the picture, the aircraft seems to be on a good path for landing, but it is an illusion caused by the wide-angle format chosen for the screen capture.

The aircraft is definitely too high. It is impossible to use the flaps to increase the rate of descent.

One must choose between 1) sideslips 2) a 360 degree turn to lose altitude or 3) multiple steep turns perpendicular to the runway to increase to distance to the airport.

What would you choose?

There is no universal method. The 360 degree turn is riskier but can prove efficient. An Airbus A330-200 flown by Quebecer Robert Piché that had lost all of its engines landed successfully in the Açores in 2001 after attempting a last minute 360 degree turn to lose altitude. But here, I did not believe there was enough altitude to safely complete the turn and reach the runway.

A few steep turns were made to extend to ride to the airport. Why steep turns? In order to avoid getting closer to the airport before an acceptable altitude was reached. This method helped keep an eye on the runway at all times to verify if the slope to the airport was still acceptable.

Fourty degree turn to the right on the approach to the Bonners Ferry's airport.

I tried the three methods, always starting from the same saved flight (photo 10). After several sideslips, the aircraft was always approaching the airport too quickly. There was not enough time to lose altitude. The final speed always happened to be too high to stop a C-130 without flaps or thrust reversers.

The 360 degree turn, be it right or left, with different angles and a reasonable speed, always incurred a loss of altitude that brought the aircraft 200 to 300 feet short of the threshold.

Finally, after a few steep turns, the aircraft was positioned on final with the appropriate speed and altitude.

The regional jet CRJ-900ER and CRJ-700ER by Digital Aviation and Aerosoft

The reason for the delays and the positive side for the consumers

A virtual Bombardier regional jet CRJ-900ER (Aerosoft) with the Alaska Airlines colors is climbing after its departure from the Valdez virtual airport in Alaska (ORBX).
A virtual Bombardier regional jet CRJ-900ER (Aerosoft) with the Alaska Airlines colors is climbing after its departure from the Valdez virtual airport in Alaska (ORBX).

Digital Aviation & Aerosoft have finally completed their long awaited project to make a virtual CRJ-900ER and CRJ-700ER Bombardier regional jets. Months later than expected, the flight simulation enthusiasts can now try those two new virtual aircrafts. The CRJ is mostly used to link smaller airports and remote areas to the main hubs. The aircraft can rapidly reach its cruising altitude and stay there a long time, but it is not intended to be a really fast aircraft.

The company explains that, since the beginning, it had underestimated the complexity of the project and, because of ongoing delays, ended up having to catch up with the competition. In order to offer a superior product than the competition, Digital Aviation and Aerosoft had to review what it initially considered as an almost completed project.

The CRJ-900ER and CRJ-700ER had their exterior almost completely redone; the consumer now ends up with a much better looking aircraft. The project manager says that it is only due to the patience and kindness of potential customers that the project was saved. It pays to be nice!

The first flight with the CRJ

Virtual CRJ-900ER aircraft with the Air Nostrum colors departing the St. Maarten international airport (Fly Tampa St.Maarten)

For the first flight, the manual recommends to first choose and activate one of the default FSX aircraft with the engine running. The pilot then selects the CRJ of his choice. It seems that doing so will prevent a lot of problems.

The virtual 2D cockpit

The virtual 2D cockpit helps save a few FPS. An easy access to the different sections of the cockpit is available since it is divided in several logical panels numbered from 1 to 9.

Navigation

The virtual pilot has access to an updated NavDataPro (May 2017) database for air navigation. It is the world’s most used database in aircraft. The aircraft is also compatible with the popular Navigraph database.

How does a standard computer deals with the new CRJ?

I have flown both aircrafts on several virtual airports like St. Maarten (Fly Tampa St. Maarten), Montreal international (Fly Tampa Montreal), Denver international (Flightbeam Studios) and Valdez (ORBX) without problems with regards to the computer’s processors and FPS. It was certainly out of question to try to land at the Courchevel airport (LLH Creations), with its short sloped runway, but a low pass at high speed caused no stutters.

Flying the CRJ at low speed

The CRJ offers a good margin of manoeuver when it comes to flying at low speed. But due to the position of the engines, the aircraft’s nose will raise rapidly when the throttle is brought back to idle. In a constant and progressive descent, that does not cause a problem. But if the manoeuver is done on short final when the aircraft is still above 50 feet, the rapid change in the aircraft’s attitude could induce a stall.

The air brakes

One cannot rely too much on the air brakes to slow down the CRJ. They have limited efficiency, both for the virtual and the real aircraft.

Floating tendency

If the aircraft arrives over the threshold at a higher speed than recommended, it will float for a long distance before finally touching down.

Landing and take-off distances

A virtual CRJ-900ER aircraft with the Air Canada colours (Aerosoft) is approaching the Montreal Pierre-Elliott-Trudeau virtual airport (Fly Tampa Montreal)
A virtual CRJ-900ER aircraft with the Air Canada colours (Aerosoft) is approaching the Montreal Pierre-Elliott-Trudeau virtual airport (Fly Tampa Montreal)

The CRJ-900 and CRJ-700 operate on relatively short runways. The CRJ-700 needs 5040 feet for take-off (at maximum weight) and landing, under the standard ICAO conditions. The CRJ-900 requires 6060 feet for take-off and 5260 feet for landing. The maximum range has been established to be around 1300 and 1400 nm.

Managers that facilitate the use of the CRJ

For the CRJ, Digital Aviation & Aerosoft have created managers that allow choosing the number of passengers, cargo, as well as calculating the fuel weight, the center of gravity and the amount of trim required. There is even a FS2 Crew option if desired. Another manager facilitated the addition of liveries.

The flight simulation enthusiasts had been anticipating the arrival of that regional jet for a long time; some did not believe anymore that it would one day become a reality (that includes the company too!). The flight simmers now have access to a world class and high quality regional jet.

From Chile to Rothera, Antarctica, with the BAS Twin Otter and the FSX flight simulator

Aerial view of the Rothera research station in Antarctica.
Aerial view of the Rothera research station in Antarctica.

For this flight, you will need the Antarctica X flight simulation software made by Aerosoft.

The maintenance of BAS Twin Otters and their Dash-7 is done in Calgary, Canada, and head to Antarctica during the austral summer, between October and March. So if you want to try a flight simulation with a Twin Otter or a Dash-7 from Chile to Antarctica, pick one of those months as it is more realistic.

Since it would be a bit long to make all the virtual flights from Canada to Antarctica, I chose to do the last three legs to see what the landscape looks like.

A Twin Otter is normally approved for a maximum take-off weight of 12,500 pounds. But with skis weighing 800 pounds and additional fuel required to fly longer legs, BAS (British Antarctic Survey) has arranged to have their Twin Otters approved at 14,000 pounds. Even at this weight, the aircraft could still operate on one engine.

First, the aircraft departs La Florida airport (SCSE) in Chile, after a mandatory fuel stop before its next destination, the El Tepual de Puerto Montt airport (SCTE), also in Chile.

For the screen captures, FTX Global, FTX Vector and Pilot’s FS Global 2010 were installed. Orbx has also reworked the original El Tepual de Puerto Montt airport to include some people, aircrafts and new buildings. It makes for a more interesting destination.

This flight, made low across the Andes, absolutely requires good weather. You will have to climb to 17,000 feet to make the direct route between the airports.

There are often spectacular views available to the virtual pilot. Yes, the BAS Twin Otter is flown by only one pilot, but there is always somebody else accompanying him.

Don’t forget to lean the mixture during the climb. Also use some additional oxygen (!!) if you don’t want to start singing and flying in circles after a while. Again, pay attention to the mixture during the descent, considering that you will be losing close to 17,000 feet.

Refueling at Punta Arenas, Chile.
Refueling at Punta Arenas, Chile.

The Punta Arenas airport, straight from FSX, is not an interesting airport to look at. It is a very bare airport, with just a single building and a VOR.

But since the BAS pilot do that mandatory leg just before heading to Antarctica, I chose not to change the route. The general direction for the flight to Punta Arenas was 164 degrees and the duration approximately 4:28 hours. You can obviously accelerate the process once the aircraft is established at its flying altitude.

The last flight is from Punta Arenas, Chile, to Rothera, Antarctica.

The Twin Otter will take between six and seven hours on an average heading of 162 degrees to cover the distance between Punta Arenas (SCCI) and Rothera (EGAR).

The runway at Rothera is made of gravel and is 2953 feet long. That is plenty for the Twin Otter and the DASH-7. Before you make the flight, go into the aerosoft/Antarctica X file in your flight simulator and click on the “LOD 8.5” option (the default is at LOD 4.5). It will give you much better details when you are approaching Antarctica.

The Airliner World magazine had an excellent article on the BAS operations in Antarctica in its March 2017 edition. It included plenty of interesting pictures and detailed explanations on what is expected from pilots and personnel working for BAS. I compared the Rothera virtual airport with the real one through the available pictures in Airliner World and was pleasantly surprised with the level of accuracy of the details.

The BAS always prepares itself for the worst: “[It] carries parts valued at around $5m, including a replacement engine for each aircraft, spare props and undercarriage components”.

A new development for the Air Unit has been its work with the RAF, using C-130 Hercules transports to airdrop supplies into the field. They fly from Punta Arenas and drop fuel to support our science programmes on the Ronne Ice Shelf. […] It is all part of their training system and the accuracy they drop to is very impressive. They might drop 250 drums, think how many Twin Otter trips that would have been for us (48 or more than 400 flying hours)”.

Naturally, we are talking about a virtual flight. You must then forgive the landing of an aircraft which, in real life, would destroy the runway. You also have to disregard the fact that numerous trees would have to be chopped if the aircraft would elect to use the taxiway. I was almost forgetting the pilots and airport manager that would have to be fired following the authorized manoeuver.

The context of the flight having been presented, here is the data that will allow flight simulator enthousiasts to replicate the circuit around the Block Island airport with a Virtavia C-17A.

Contrary to the Cessna type aircrafts normally evolving around the airport, the total weight of the canadian military C-17A used for the flight was 405,000 pounds. The fuel was adjusted to 50% in all four tanks. Both pilots agreed to skip lunch in order to avoid adding any extra weight to the beast…

Flaps were adjusted to 2/3. I backed the aircraft to the beginning of the runway, applied the brakes, applied full throttle, waited for maximum regime, released the brakes and used ground effect to lift the aircraft before it was too late. The take-off was done on runway 10 with a 12 kts and 70 degree crosswind.

Then, four right turns were made : 190°, 280°, 010° and 100°. During the flight, the aircraft’s altitude never went above 2000 feet.

Wheels and flaps were brought down in base so that I did not have to make serious adjustments on final.

The speed eventually went down to 128 kts and, while the aircraft was still about two feet in the air, I used the airbrakes. The thrust reversers were fully activated two feet before touch-down (continued pressure on F2) since they take time to rev up. That is not necessarily the proper way to do it and you can wait one more second, until the wheels touch the runway, to use the reversers. The main gear touched at the very beginning of the runway and maximum breaking was then applied.

It was possible to exit on the taxiway without having to back-track on the runway. The environment always coming second, some trees were cut so that there were no contacts with the aircraft.

If you decide to try it out, think of saving the flight when you are on final, in case you are not satisfied with your performance during the landing (scrapped aircraft, destroyed houses and vehicles in the neighborhood, burned forest at the end of runway 10, collateral victims, etc.).

Flight simulation: the “Tapini” virtual scenery in Papua New Guinea (FSX)

Ken Hall and Tim Harris have created a new virtual scenery for flight simulation enthousiasts. It is called “Tapini” and sold by ORBX. Their penultimate creation, AYPY Jackson’s International, allowed the virtual pilot to fly in very demanding virtual airports along the Kokoda Trail in Papua New Guinea. “Tapini” represents a whole new challenge and I have included several screen captures to show you how the different runways look in this new virtual scenery.

“Tapini”, still in Papua New Guinea, allows the virtual pilot to test his skills on seven new runways located in difficult areas of the Owen Stanley Range. Those airports also constitute a serious test for any aircraft, like in the picture above where damages to the right engine were sustained at Yongai.

To improve the virtual clouds while flying between the different airports, I used either REX or FSGRW weather engines. The cloud textures and weather effects were improved by one or many of the following products: Cumulus X, PrecipitFX, REX Texture Direct and REX Soft Clouds.

As variety is more fun, and also due to the different challenges created by those runways, the following virtual aircrafts were used: Carenado C-185F,  Lionheart Creations PA-18,  Virtavia DHC-4,  Aerosoft DHC-6 Twin Otter and Milton Shupe DHC-7.

The “Tapini” scenery gives the pilot a choice between the seven following runways:

ASB (Asimba)

A tricky, very short runway near a river.

This is a very interesting runway, best done with a STOL aircraft like the Caribou DHC-4. The inhabitants might have to help you clear out some branches along the runway, considering the size of the aircraft. The runway slopes down on take-off, which helps to build up speed.

FNE (Fane)

A one-way, really challenging 12 degree sloped runway, with unpredictable winds.

The runway sits on top of a hill. It is an amazing experience to land there. No wonder there are a lot of people watching the arrivals and departures.

If you slow down too quickly with an aircraft as big as the DHC-7 on that sloped runway, the twelve degree angle prevents you from moving forward. You must let the aircraft come down the runway very slowly, using the power to control the descent and the rudder to stay aligned on the runway, then apply take-off power for a few seconds to build just enough momentum to get above the hill.

To turn the aircraft around, it’s a combination of power and reverse thrust until you clear all the obstacles (any humans venturing behind the aircraft will also be cleared during the operation…).

There is a not so friendly man with a rifle watching the airport’s operations. Even the United Nations staff do not stay longer than necessary…

KGH (Yongai)

A very bumpy one-way sloped runway. A real bush aircraft is needed here!

Even with a real bush aircraft, there is a possibility that one of the aircraft’s propellers hits the ground while taxiing on the runway. There are so many deep holes that are hard to see, I can only wish the best of lucks to everyone trying out this airport!

Keep a close watch on the area near the little house at the end of the runway. The DHC-6 was really shaken while turning around for take-off. One of the propellers hit the ground but no problems were detected…until the aircraft was airborne. The fire alarm then went off, just as the aircraft was passing the runway threshold, seconds before flying over a cliff.

So much for the planned trip… and it was out of the question to return to Yongai on one engine. I had to pull the handle to stop the fire, feather the prop, cut the fuel where it was not needed anymore then head to the Kokoda airport as it was a sure alternative, having a long runway and an elevation that did not require the use of extra power.

KSP (Kosipe)

A relatively short runway that requires good calculations from the pilot, since it is located high in the mountains.

The Cessna C-185F is a very well suited aircraft for that runway. Make sure not to be too heavy on the brakes, as new C-185 propellers are hard to find in Kosipe. You can land in both directions. Ensure that the mixture is set properly as the airport is above 6300 feet.

ONB (Ononge)

A curved and very bumpy runway! For those who like low flying. Make sure you choose the good aircraft here; there is not much manoeuvering area once on the ground.

Ononge looks really scary when you show up on final for the first time. You wonder if the little trail that you see can really be a runway. For that kind of situation, the little Piper Pacer is an excellent aircraft, approaching slowly and braking on a dime. The runway is curved in the middle so you will need a bit of right rudder to keep the aircraft aligned with the runway.

TAP (Tapini)

A challenging one-way sloped runway nestled in a tight valley. You can even use an ILS to arrive there!

This is a superbly designed area and airport. I visited it with the DHC-4 Caribou but any other big STOL aircraft would have fitted there. There is enough room to manoeuver. It is not too bumpy. There is an interesting slope: it starts downward and ends upward: this helps to slow down the aircraft after landing.

WTP (Woitape)

Looks like a no brainer, but there is no margin of error on this one-way slightly sloped runway. Very precise calculations and settings are required if you want to land there with something else than a small aircraft.

I found the runway to be very slippery with the De Havilland DHC-7. I must say that there was a good crosswind, as I was flying with real life weather and winds. The DHC-7 behaves like a big boat while decelerating on such a runway.

The Woitape scenery is gorgeous. It is nice to have all those well designed virtual aircrafts, people and animals on site as this makes the scenery so much more realistic.

I love this new Orbx product. When you fly in such a realistic scenery, the brain does not make much difference between what is real and what is virtual. It really works! And if you use real life weather downloaded from the internet, it’s even better.

I tried the seven airports included in the “Tapini” virtual scenery and they are quite demanding. Yongai was the most challenging airport of them all. I had to do two missed approaches there since I ended up too high on the approach. I eventually got it right, like in real life!

I used the Microsoft flight simulator X (FSX) for all the virtual flights, but other platforms would have worked as well (Dovetail Games FSX Steam edition (FSX: SE) and all versions of P3D). The following products were also installed on my flight simulator: FTX Global, FTX Global Vector and Holgermesh, as well as Pilot’s FS Global 2010.

It is a totally immersive virtual experience and you have to forget everything else when undertaking those challenging virtual flights… if you want to make it “virtually” alive!

If you feel like attempting a virtual landing on an ice runway, an opportunity is offered by ORBX through their Homer (PAHO), Alaska virtual airport. For the flight, I used the FSX platform but it could have been also done under P3D.

The ice runway is just a short distance away from the regular Homer asphalted runway. The DC-3 is an excellent aircraft for the task since its approach speed is very low and it is one of the few virtual aircrafts equipped with skis.

If you want to try that flight, make sure to adjust the flight simulator configuration settings so that the Homer ice runway option is activated, otherwise you’ll end up under water…

In order to add a bit of challenge as well as winter realism, you can add a bit of crosswinds or some snow using the standard « heavy snow » option in FSX. The program PrecipitFX helps a lot if you are looking for a better definition of precipitations, be it snow or rain. For this flight, the Cumulus X program was also activated.

The short flight proved to be an interesting experience, since the runway was narrow and there were some crosswinds. I thought that it would be very slippery but it was not the case. Maybe one day Orbx, in association with the FSX Steam (Dovetail Games) professionals, will work at modifying the flight simulation platform and add a CRFI (JBI) index of .40 or less to increase the difficulty in slowing down and controlling the virtual aircraft?

As this flight is not a super though exercise, I have placed it in the “standard virtual flights”, in the flight simulation section of my website. For more of those flights, click on the following link: Other standard virtual flights

Have fun trying this one! Later on, I’ll present another ice runway located on Antarctica, which virtual scenery was made by Aerosoft. Even the C-17 Globemaster III is approved there…

Virtual aviation: the PMDG MD-11 under FSX

This screen capture represents the PMDG MD-11 inbound for the Valdez virtual airport in Alaska. The scenery is made by Orbx.  This virtual MD-11 is a real fun to fly in manual mode since it requires a lot of attention. A 6,500 feet runway is enough for a MD-11 but it does not offer much margin of manoeuver. (Edit: This aircraft is not supported anymore by PMDG).
