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.

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.

Arriving straight across the runways, facing the wind, the crew intends to land the aircraft a few feet short of a hangar. The captain requests that someone opens the hangar doors right away. The captain will terminate the approach in the hangar, protected from the wind.

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.

The actual ground speed of the airplane is around 20 kts.

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.

A few seconds after the touch-down, the aircraft is in the hangar, protected from the wind, and both doctor and patient can quickly head out to the hospital.

Once in the hangar, the winds were adjusted to zero, which is kind of logical, unless the opposite wall is missing!

It was now time to brace for another storm, which was the inquiry that would possibly follow the landing!

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.

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.

The Innsbruck runway is 2000 meters long. There is not much leeway for the MD-11F.

Once on the ground, you must continue until the end of runway 26 in order to do a 180 degree turn. There is just enough space for the MD-11F.

As you can see in the image below, looking at the windsock, the landing was made with a good tailwind.

The airport is superbly represented and a parking space is already reserved for bigger aircrafts. Employees are waiting for your arrival.

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!

Flight simulation: a Canadian C130 Hercules on the aircraft carrier USS Enterprise

For the challenging virtual flights category, a F18 landing on the bridge of an aircraft carrier would have been appropriate. But using a C130 was at least as demanding, due to an increased inertia and the absence of hook to slow down the plane. Since this had already been tried in real life on the USS Forrestal in 1963, it seemed that it would be an excellent exercice.

If you decide to try this exercice, expect to do few missed approaches as you get used to the narrow bridge and the more important size of the Lockheed C-130 Hercules (Captain Sim). The landing configuration with full flaps must be established a long time in advance. At the time you arrive over the bridge, no in flight adjustments must have been necessary for a minute or so on the approach. It will ensure a smooth landing.

The USS Enterprise deck height is about 130 feet and there is plenty of runway if you arrive at the threshold at the appropriate height. If there is a rebound, just apply full throttle and pull the control column slightly, as you are flying near stall speed. The approach speed should be around 110 kT. I chose to limit the fuel load to 50% in all tanks. The total weight of the aircraft was 127,000 pounds.

You will have to deactivate the option that makes the simulator react to an airplane crash. There are too many aircrafts on each side of the Big E runways and you risk hitting one of them with the C130 wings. For the real life trials on the USS Forrestal, the aircrafts on the deck had been moved away to give space to the Hercules.

There are many areas around the world where this exercice can be practiced since everything is already programmed in the TEAM SDB CVN-65 USS Enterprise software for FSX Acceleration. I chose to be airborne from San Diego (KSAN)and followed a heading of 257 degrees over 108nm. The USS Enterprise is located at 32,31.647N 119,1.802W. The month of July has been chose for the screen captures. The flight was done at 17h30 and the weather theme was ORBX5.

It is a demanding exercise that you will certainly appreciate. Have a good flight! If you feel like it, tell me how it went!
