Challenging virtual flights : the interception of aircrafts in flight simulation.

An interesting challenge for flight simulation enthousiasts consists in searching and intercepting virtual aircrafts that are flying randomly: those without any known flight plans.

The degree of difficulty varies accordingly with the intercepted aircraft and the interceptor.

The screen capture below shows a relatively simple interception since it is not too difficult for the AV-8B Harrier to modify its speed according to the high cruising speed of a Beechcraft B350.

In order to increase the difficulty, the flight simmer could attempt the interception in flight of a relatively slow aircraft with a military jet.

A challenging virtual flight can be executed by using a CF-18 and adapting its speed and altitude to that of the intercepted aircraft while flying in formation for one minute. In order to succeed, it will be necessary to set the CF-18 in a slow flight configuration with the wheels out.

This type of interception is sometimes done in real life when an aircraft accidentally (or not) enters a restricted zone. A military jet must then take-off, reach the unknown target, get very close and make the appropriate signals ordering it to follow him to the closest military base.

Once in flight, do not forget to take a screen capture! Good luck and have a good flight!

The Martinair Cargo MD-11 on a virtual VFR approach in Innsbruck

Manually flying a huge aircraft like the MD-11F to make a virtual landing in Innsbruck surely will be fun for most flight simulation enthusiasts. Since the Innsbruck airport and its surroundings have been redesigned under ORBX Innsbruck, the immersion feeling is total. The landscape is absolutely fantastic.

A virtual Martinair Cargo MD-11F is airborne from runway 26 at the Innsbruck airport (LOWI)

Start by taking-off from runway 08. Anybody standing near the fence at the end of the runway will feel the blast. Then, gain enough altitude to be able to do a 180 degree turn to realign the aircraft for runway 26.

Make sure to activate the “air turbulence” option on your virtual weather engine, since an approach near the mountains in Innsbruck generates enough turbulence to make your approach more difficult. The pilot must also, for this exercise, deal with the actual winds even if they do not favor runway 26.

The flaps must be adjusted to 50 degrees for the MD-11F. Insure that the “Autopilot” function is set at “OFF”. The intensity of the automatic breaking is chosen according to the actual winds, the aircraft’s cargo load and the altitude of the airport. The margin of manoeuver with regards to the approach speed is not very large. I tried to maintain 150 kts.

You can try landing with any other big carrier if you do not already own a PMDG virtual MD-11. If you would like to acquire this aircraft, you will realize that it is no longer offered by PMDG, at least for now. Try to put some pressure on the company so that they restart offering the aircraft on which they have put in so much effort. A message on their Facebook site should show your interest: PMDG

If you would like to see an exceptional two hour aviation video on a real flight that lasted ten days across the world, there is none better than the one made by PilotsEYE.tv: Lufthansa Cargo MD-11F in Quito

You witness part of the crew’s planning for a landing on the old Quito runway, in Ecuador. The airport’s altitude is so high that the MD-11F margin of manoeuver is extremely limited. Make sure to own a player that can decode European videos.

Have a good flight!

The PMDG MD-11 and flight simulation

A Brazilian VASP MD-11 aircraft is on final for the Guarulhos international airport in Sao Paulo.
A Brazilian VASP MD-11 aircraft is on final for the Guarulhos international airport in Sao Paulo.

The picture above shows a virtual MD-11 aircraft with the VASP livery over Sao Paulo. In the flight simulator, I positioned it on final for the Guarulhos international airport in Brazil (IATA: GRU, ICAO: SBGR). This MD-11 was created by PMDG.

The landscape is modelized by ORBX and is made of overlapping layers of their different products in order to achieve this final aspect. There is first FTX Global Base Pack, then FTX Global openLC South America and FTX Global Vector. The last touch is added through FTX Global Trees HD, but it is not really visible here due to the late hour.

The two pictures above show a MD-11 just airborne from Innsbruck, in Austria. The landscape of that region, in real life or virtual mode, is absolutely stunning. I am essentially using the FSX flight simulation platform for now, but I am always monitoring the progress made with Aerofly FS2. The virtual cloud textures for the three pictures are modelized by Rex Simulations and the weather engine used for the flights was  FSGRW.

The MD-11 is an extremely interesting aircraft to fly in the flight simulation mode but it seems that PMDG is not bringing the aircraft up to date to follow the evolution of Microsoft operating systems. It has not been modified neither to work with P3D or other virtual flight platforms. Nevertheless, if customers start expressing their interest in that aircraft, I am convinced that PMDG would allow a bit more research in order to bring that MD-11 with today’s standards of flight simulation ( https://www.facebook.com/pmdgsimulations ).

The documentation offered for the MD-11 by PMDG is really complete. All the articles written in the PC Pilot magazine on how to fly the aircraft are also still available today in only one download.

The Captain Sim’s B-52 in flight simulation

Here are a few modified screen captures of a recent virtual flight made with the Captain Sim’s B-52.

The high quality of the modelized clouds and of the landscape in the background helped create screen captures that were even more realistic. FSX was the flight simulation platform used for the flight.  REX Simulations made the virtual cloud textures.

The landscape is a creation of ORBX. At the base of the three screen captures were the following ORBX products: FTX Global Base Pack, FTX Global Vector, FTX Global Open LC North America, FTX Global Trees HD and NA Southern California. The time for the flight was early in the morning.

In the picture below, a few modifications were made using Photoshop to induce a feeling of speed. When comes the time to modify the screen capture of a virtual aircraft with an image editing software, the same rules apply as for a normal picture: moderation gives better results.

The sound of the Boeing B-52’s eight engines is quite impressive. Despite the enormous power available for take-off, the flight simulation enthousiast cannot simply apply full power and hope that the military jet will get airborne. By the book procedures have to be followed, otherwise there won’t be any take-off. A parachute can be deployed when landing for a better visual effect, but the flight simulator will not include it in its calculations for the required landing and breaking distance.

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

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

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.

Flying in and out of Limberlost Ranch (CA21)

The following pictures show a virtual flight in United States. The trip is from KBLU ( Blue Canyon-Nyack) to Limberlost Ranch (CA21) then to Gansner Field (201). Landing and taking-off from Limberlost Ranch is a nice challenge.

For this flight simulation, I used the FSX flight simulator, the Carenado Cessna C-207 equipped with bush tires and REX clouds.

Airborne from KBLU.

Enroute from KBLU (5284 ft ASL) to Limberlost Ranch and it’s 1700 ft grass runway (1650 ft ASL and about 23 NM east of KBLU), you pass by the Nevada County airport (O17) that has also received a special treatment from ORBX.

It might be necessary to fly over the Limberlost Ranch airport before starting an approach, so that you have an idea of what to expect on final.

Over the Limberlost Ranch short and sloped runway

Limberlost Ranch has a sloped runway (in fact, a multiple slope runway). Part of it is asphalted, but most of it is grass. You make the approach for the grass section. Note that there is a fence on the side at the beginning of the runway. The virtual aircraft should not touch the field before it has passed the fence (for more realism).

With a bit of crosswind, taking-off from this short runway can be demanding. The aircraft feels really sloppy (and I mean it) and behaves more like a boat than a plane during the acceleration to get airborne. It is essential to avoid the line of trees on the left side of the runway. A bit of flaps is required as it is the norm for soft runway operations. Careful but essential use of the rudder will also make your take-off a success.

Gansner Field is about 41 nm north of KBLU. The virtual airport is very well made and nestled in a valley. Coming in from KBLU, you need to pass 6000 ft mountains before diving for that 3419 ft asl asphalt runway.

The fully enjoy those virtual flights, it is suggested that you install the different layers of Orbx products (Global, Vector, Open LC) as well as the KBLU virtual scenery.

Have a good flight!

The screen capture above represents a Beech Staggerwing virtual aircraft available through the Carenado company, in flight early morning on a winter day over Saskatchewan, Canada.

Houses and the general scenery are a creation of the Orbx company, through their FTX Global Base Pack, FTX Global Vector and FTX Global openLC North America products.

The virtual clouds are a creation of REX Texture Direct and Soft Clouds. There is also an additional touch of drama through the use of Cumulus X. The virtual flight platform used was FSX.

In April 2017, Orbx again released new improved virtual airports for North and South America, available for free for flight simulation enthousiasts already using their commercial products. That was one more reason to go flying in Saskatchewan!

Flight simulation: the North-Wright Airways Ltd Cessna 185F C-GNWA

Virtual Cessna 185F C-GNWA on final for Roberts Lake (CRL8) in Ontario
Virtual Cessna 185F C-GNWA on final for Roberts Lake (CRL8) in Ontario

This virtual Cessna 185F is seen here on final for Roberts Lake (CRL8) in Ontario. Due to the prevailing wind at the time of flight, I had to do the approach overflying the Parry Sound (CNK4) airport runway. Real weather was downloaded through internet.

As you can see, there was some bad weather near the airport. Considering that nightime was coming, it was the last flight of the evening.

C-GNWA belongs to the North-Wrights Airways Ltd company, based in Norman Wells, Northwest Territories. This particular Cessna 185F was built in 1977.

The flight simulation platform used to do the flight was FSX. The virtual clouds are a combination of REX (Texture Direct with Soft Clouds) and Cumulus X. The screen capture was slightly edited using an image editing software in order to optimize the contrasts and brightness.

Vlad Maly, who died in 2016, was the creator of this virtual scenery combining Parry Sound and Roberts Lake. It is sold by Orbx.

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.

This virtual flight with the Twin Otter last about 4:25 hours (696 nm) with a heading of 185 degrees.

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)”.

Aerosoft has made an excellent job in replicating the buildings in Rothera, BAS’s main research station in Antarctica. The biggest hangar can accommodate three Twin Otters and a Dash-7 altogether.

Flight simulation: a FedEx MD-11 inbound for the Telluride airport (KTEX) (FSX)

The flight simulator enthousiast will have fun trying this short flight ( 14 minutes) from the Eagle County virtual airport (KEGE) to the Telluride virtual airport (KTEX). The virtual flight, using FSX, was made during winter, on January 8th. The shots below represent an idea of what is visible while flying toTelluride. Use 14,000 feet, it should do it…

The expected ceiling at Telluride was 8500 ft. On the way to the airport, the clouds and visibility were sometimes obscuring the mountains.

Telluride is a very inviting airport for a MD-11. The 7000 feet runway itself does not represent a big challenge, although its 100 feet are a bit narrow: this aircraft would normally require a 150 feet wide landing surface.

The virtual VFR approach made with the MD-11 was the most expensive way to do the trip, since it required a fly-by and a 270 degree turn to the right to align with runway 09.

The 270 degree turn at a 10-20 degree bank allowed to transit from 14,000 to 10,000 ft without doing anything radical. Just a turn while descending and gradually loosing speed to arrive at around 160 kts on final. The aircraft was now installed on long final, with flaps set at 50 degrees.

The high altitude runway’s 9078 feet msl elevation meant the pilots dealt with lower air density and heavy weight when approaching and, as such, the airspeed had to be adjusted accordingly to prevent stalling on final.

To prevent an overshoot and some additional expenses in fuel (which are already skyrocketing), an optimal approach was required.

Most accidents with the MD-11 happen when the pilot pushes on the stick when there is a rebound with the nose wheel, thus creating an even stronger rebound. When there is a rebound, there is no need to push on the stick, just wait and the aircraft sets itself quickly.

The employee on the ramp was worried that the MD-11 lower winglet would scratch N900SS while taxiing. But there was plenty of space (11 inches)…

The MD-11 was parked temporarily in a spot needed by every aircraft. It was necessary to unload quickly the precious cargo and get out of the way.

Some expert handling would be needed to help move back that MD-11 close to the runway. But that was the Telluride’s airport manager problem and he had promised he would have something ready!

The virtual scenery from departure to destination is a creation of ORBX programmers and the virtual MD-11 is made by PMDG Simulations (I am not sure it works with P3D though). For the weather, I used REX Simulations as the weather engine and REX and Cumulus X for the cloud textures. (Edit: PMDG does not support it’s MD-11 anymore).
