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…

Flight simulation : St.Barths (TFFJ) with the Aerosoft Twin Otter in FSX

Well, let’s start with a real life video showing that there is no margin for error when landing in St.Barths :

In that video, you can clearly see that the speed on the approach seemed excessive and the aircraft floated precious seconds over the runway. Very soon, there wasn’t enough runway left to stop the aircraft safely. So the trick is to use a reasonable approach speed and be ready to do a missed approach if the wheels do not touch early on the runway.

An approach with a  virtual aircraft of your choice can be done in St.Barths (TFFJ) since FlyTampa St Maarten scenery includes that airport. I tried a circuit with the Aerosoft Twin Otter, under FSX, and it went very well, since this aircraft can fly at a very low speed and can break on a dime. It might have been a different story with the same aircraft that pilot was flying in the video…

For your information, the St.Barths 10-28 runway is 2133 ft long. For the landing, the winds where blowing from 031/10G20, which provides for a good crosswind. The biggest aircraft to have landed in St Barthélémy is a Canadian built de Havilland DHC-7.

Flight simulation : Juancho E. Yrausquin Airport, the shortest commercial runway in the world (FSX)

One nice challenging virtual flight in FSX is to operate from the Juancho E. Yrausquin Airport, the shortest commercial runway in the world.

The runway is 1299 ft long (396m) and 60 ft (18m) above sea level. The IATA code is SAB, and the ICAO code TNCS.

The ideal virtual aircraft for that runway is the Twin Otter (DHC-6) or the Britten Islander (BN-2). If you want something bigger, the De Havilland DHC-7 is going to be your perfect choice. Forget about jet aircrafts, the runway is too short.

To add to the pleasure, use runway 30 and add a strong crosswind component, with gusts. In the screen captures below, I set the winds to 030 degrees at 10G20. For the flight, I also used Cumulus X and  PrecipitFX to improve the visual effects.

For an even more realistic experience, I suggest you get the FlyTampa St.Maarten scenery, which will offer you three airports, which are all very well designed and present real challenging approaches : the Juancho E. Yrausquin airport, on Saba Island,the spectacular St.Barths airport and the Princess Juliana international airport in St.Maarten.

In the « challenging virtual flights » section of my website, I have already included an approach to Princess Juliana airport in St.Maarten, with the MD-11. The approach to St.Barths (TFFJ) will soon be included.

You will enjoy every minute trying to make perfect landings at those three airports. For other challenging virtual flights, visit the flight simulation page of my website.

Have fun!

Flight simulation : Lukla, the most dangerous airport in the world (FSX)

If you are looking for a challenging virtual flight, why don’t you try the route Syangboche –Lukla with the Aerosoft Twin Otter? It is a very short flight, few minutes only, where the aircraft will be constantly descending until its destination.

The approach in Lukla can be tricky due to a 12 degree sloping runway. You have a feeling of coming in too quickly, but you must resist the temptation to reduce speed since, at this altitude, the stalling speed increases with all aircrafts.

Runway 06 is used for landing, and 24 is for departures. There is no possibility of a missed approach. You either succeed or you crash since there is a high rock wall at the end of  runway 06.

So the flight is made from Syangboche (OACI code:VNSB, altitude : 3748m and a 400m runway) towards Lukla (OACI code:VNLK, altitude 2860m and a 460m runway).

The scenery and objects around Syangboche are a creation of ORBX. Once you get closer to Lukla, you will notice a change in the scenery details, since you are entering the Aerosoft Lukla scenery (you have to buy this additional scenery to make the flight more realistic).

Flight simulation allows the use of all company liveries and types of aircraft. In the present case, a DHC-8-227Q from Sat Airlines, with the Sakhalin Energy logo, has mysteriously found itself inbound for the Peyresourde mountain airfield.

Peyresourde Balestas is located in the Pyrenees, at an altitude of 1580 meters. Its runway is only 335 meters long and has a 15 degree slope. The beginning of the James Bond movie “Tomorrow never dies” has been filmed there. The runway is long enough to accommodate the DHC-8-227Q as the plane’s excellent braking capacity is even improved by the sloped runway. If you touch early enough, you won’t even have to apply full braking power.

A Dash 7, with its superb ability to operate from any kind of field, would also fit in there, providing the amount of fuel and cargo is well calculated. Because what lands must also takeoff.

The Peyresourde Balestas mountain airfield is made by LLH Créations, from France. The company has already produced four mountain airfields located in the French Alps. This is the first one in the Pyrenees.

Virtualcol FS Software created the Dash-8 used for this flight. For a very reasonable price, that company offers, in one bundle, an astonishing amount of liveries and all the types of DHC-8. Their product is detailed enough and really takes lower end computers into account when it comes to FPS (frames per second). Don’t expect the same realism as with the Q400 from Majestic Software though: Majestic’s Q400 is on a category by itself in the sim world and the price is adjusted accordingly.

The fun will not be over after you land. You will find that the takeoff is quite spectacular. Apply the brakes, full power and the necessary amount of flaps and let it go! You’ll see that the runway’s end is coming quickly and that you’re building speed like you never believed possible with a Dash 8!

In the « flight simulation » section, under « challenging virtual flights », you will soon find screen captures representing the DG-808S glider built by DG Flugzeugbau. The flight departed from the Parry Sound airport (CNK4) in Ontario. The scenery has been created by Vlad Maly, from ORBX.

The command CTRL+SHFT+Y will allow an aircraft to appear and a cable to be installed between the aircraft and the glider. It is more demanding to do gliding operations in the Parry Sound region because if the pilot gets far enough from the airport, he leaves behing many options to help him land easily in case of difficulties. There are not many fields or roads. There are mostly lakes and forests. The view is interesting, but you fly with the feeling that there is really no plan B. If the glider must go down, chances are it will find itself either in water or on the top of trees.

The DG-808S can reach a speed up to 146 kT and has a gliding ratio of 5o :1. It is a high performance glider. It can carry up to 343 pounds of water to be used as ballast. In real life, the pilot uses the necessary amount of water according to the prevailing weather conditions. If there are weak thermals, the glider will easily operate without water. If there are strong thermals, it carries the maximum amount of water in its wings to add sufficient weight.

In the “flight simulation” section, under “challenging virtual flights”, I have added screen captures (also visible here for now) that show a flight that can be quite demanding and which consists of doing a VFR ride  with an helicopter between two helipads situated high in the Alps. The flight is made using FSX. In real weather conditions, the winds can really complicate things when you are on short final for your destination.

For this exercice, the ALABEO R66 has been chosen. You could add another degree of difficulty by using a DODOSIM helicopter.  The helipads are made by  LLH Créations. The virtual flight that you can see in the screen captures set  above shows a takeoff from the Refuge du Requin sur la Mer de glace (DZRR), which is at an altitude of 2510 meters, towards the Refuge de l’Argentière (DZRA), located at  2778 meters MSL. Two other mountain chalets could have been chosen: Chamonix (DZ des Bois , DZDB), at 1075 meters, and Promontoire (DZPR), near the Alpe d’Huez mountain airfield  and Grenoble airport,  at 3055 mètres in the mountains.

I am convinced that you will enjoy the experience. By using real weather, each flight becomes an adventure. With moderate winds, on an approach to the Refuge de l’Argentière, you will realize that there is not much margin of manoeuver!

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.

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

FedEx MD11 in flight (FSX). This virtual aircraft is made by PMDG.

The MD-11 is an extremely interesting aircraft with regards to its characteristics but many pilots have had problems to master all its interesting features in real life. It’s partly for that reason that there has been many crashes with this type of aircraft. Considering the MD-11 high fuel consumption, FedEx will progressively start selling them, starting 2015. The only company in the world still using the MD-11 to carry passengers is KLM (edit: it did the last flight with passengers in 2015). The MD-11 is remembered for the Swissair 111 crash, near the coast of Nova-Scotia, on Septembre 2nd, 1998. It was flying the New-York to Geneva leg when the accident happened: 229 persons perished when the aircraft plunged into the sea.

The above screen capture has been edited to give it a more realistic effect and to emphasize the quality of light at dusk. Different images, under many company colors, can be found on this website under the « flight simulation” category, within the ” virtual pictures » section. A flight from Mexico City Intl to Denver Intl will soon be included in the « challenging virtual flights » section. Have a good visit!
