The treacherous Launumu short sloped runway in Papua New Guinea.

An Air Saguenay DHC-3 Otter has made it from Québec to Kokoda, in Papua New Guinea. It is expected to work around the remote mountain airfields for a while.

The Air Saguenay Otter is taxiing for the Kokoda runway towards Launumu in Papua New Guinea.

Today, the Otter heads for Launumu, a mountain airfield that is at an elevation of 5082 ft asl and 1200 feet long.

If the mixture is not adjusted, the Otter will lose a lot of steam trying to climb up to 7,500 feet to cross the first line of mountains.

Anybody landing and departing from Launumu deals with high density altitude. This is not only due to the elevation of the airfield but also to the very warm and moist air present in the region. Consequently, some additional airspeed is required on the approach and on the departure.

When a pilot lands southwestward in Launumu coming from Kokoda, he must dive in a valley to lose altitude, which will increase the aircraft’s airspeed. The Launumu runway is in sight.

If the airspeed is not promptly corrected, the approach to the Launumu runway will be too fast. Any airspeed above 60 knots forces the pilot to overshoot (unless you are ready to virtually die a few times while trying).

So, once the higher mountains are crossed, a good way of losing altitude without gaining airspeed is to use flaps (at the corresponding airspeed) and do a tight 360 degree coordinated turn while descending. That way, the pilot will end up in line with the runway and at the speed you want, which is around 50 knots.

On final for Launumu, the pilot might end up having to deal with the bushes that are close to the runway. It is not unusual for the Otter or the Beaver to complete a difficult approach with bushes wrapped around the landing gear.

Launumu has a surprise for the newcomers. If the pilot lands southwestward, like it was just done here, and the aircraft is not stopped within approximately 600 feet, it starts accelerating since there is a pronounced slope downward in the second half of the runway. This slope leads to a cliff. In case of a missed approach, the pilot can use the slope downwards and dive in the valley at the end of the runway to build up airspeed and start a new approach.

Now that the hard work is done, it is time to wait for the passengers and cargo, and plan the next leg…

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…

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.

The Port Moresby Jacksons (AYPY) is in sight in the center top of the screen capture.

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.

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)

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.

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!

Flight simulation: Fly a Dash 7 from Kokoda to Kagi in Papua New Guinea

If you are looking for a real challenge, try a flight from Kokoda airport to Kagi, using a DHC-7. Kagi is situated along the Kokoda Trail in Papua New Guinea. The runway has a 12.5 degree slope and is approximately 447m long (1466 ft). The airstrip’s altitude is about 3900 ft msl.  You will need the ORBX scenery (AYPY) Jacksons Airport made by Ken Hall and Tim Harris, as well as other Orbx products such as Global, Vector and Holgermesh to do the flight and obtain the same views as above. In order to find the airports, two maps are included in the “User documents” included with AYPY.

I adjusted the fuel at 50% in each tank. For payload, I used 5 passengers and luggages. Obviously, the aircraft could have been loaded with many more passengers and cargo. But since it was a first trial at Kagi with a Dash 7, I thought that a lighter payload would increase my chances of a successful landing by reducing the approach speed.

The landing in Kagi is made on runway 07 and the takeoff on runway 25. From Kokoda airport, follow the Kokoda trail then, when appropriate, make a right turn toward Kagi. There are few airports within a small area so it can get a bit confusing. The best way is to overfly the area slowly to ensure that what you see in flight and what is on the map are both the same airport.

The two most difficult aspects of the approach are the steep turns required while flying close to the mountains in slow flight configuration, that is to say with full flaps and wheels out. The second problem to keep in mind is the sloped runway: 12.5 degrees is not negligeable.  But once you are on the runway, the Dash 7 will almost stop by himself due to that slope. The takeoff on runway 25 is not a problem with that aircraft: with such a sloped runway, you will be airborne in no time.

I am convinced you will enjoy this demanding flight. There are lots of plants and trees included in the scenery, so it makes for a very realistic approach. Have fun and make sure your passengers will still have a smile on their face when they get out of the airplane!

P.S.: The flight was made using FSX
