The Shorts 360 and the Juancho E. Yrausquin (SAB) airport.

In the unhinged virtual flights section of my blog, you can now find a flight with the Shorts 360 between the St.Maartens (Princess Juliana Intl) airport and the Juancho E. Yrausquin (SABA, SAB or TNCS) airport.

The official landing and take-off distances required for the Shorts 360 are longer than what the Juancho E. Yrausquin (SAB), with its 1299 ft short runway, has to offer.

But for the flight simulation enthousiast (FSX), SABA offers an interesting challenge since a very well adjusted approach, at about 90 knots, is necessary in order to use only the authorized part of the runway.

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.

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.

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.

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!

Try to land in Sumburgh, Scotland, with the Antonov 225 and the Buran space shuttle.

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.

Speed 126 kts on the Sumburgh runway, Scotland, with the Antonov 225 and the Russian shuttle Bourane (FSX)

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.

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.
