Dear Friends, I often tell my student pilots that it is wise to hold on before taking off when another aircraft has just taken off. Even two minutes is not enough sometimes because the wake turbulence may move in an unpredictable way – rather sideways – depending on the wind but not only. You can watch a previous post in which a spectacular uncontrolled roll happened: http://airforces.fr/2016/03/06/must-see-weird-takeoff-explained/ I have repeated that over and over – waiting is as wise as safe:
We cannot see clearly what really made the seaplane – assumed to be a French Canadair CL-415 Superscooper water bomber – veer off but it was definitely too close to the previous aircraft. Maybe the pilot wanted to do the right thing by saving time to save more lives. Was it because of the bow wake of the flying boat? Because of the air wake turbulence? A human error? A control failure? Or a combination of several factors? Anyway when you see an aircraft of this size taking off, please wait for two minutes before entering the same path. Fortunately, a pole was clipped, the Canadair was damaged, but it could have been worse.
Thanks to this video shared by @air_english, here is an example of the kind of accident you can avoid if you follow some basic flight safety rules. Even if nobody could expect such a spectacular accident while weather and visibility were excellent, some precautionary measures could have prevented the aircrew from a catastrophic failure. This video will let you guess what provoked this. You will find an analysis of this German Robin DR-400 accident here.
Thanks to AIR-ENGLISH and John Maxwell. Please, pass the information on for it is a flight safety issue and it could happen to anybody. It is useful for BIA-CAEA too.
An RAAF F-111 crew had to perform a belly landing. To help you understand this video in Australian English, there is information both in English and French below:
To shed / I shed / have shed: perdre quelquechose. Attention, « a shed » = un hangar, un abri, aussi un cabanon. To shed a tear: verser une larme. Masterpiece: Chef d’oeuvre, joyau, merveille. Beneath: Sous, dessous. « The F-111 can dump and ignite fuel with the afterburners »: Le F-111 peut larguer et allumer le carburant avec la postcombustion (PC). « This extreme war machine can be fickle »: Fickle = capricieux, instable, imprévisible. In Aussie (in Australian, say [ozy]) language: Brake mechanism, (dites [braïk mekeunizeum]) mécanisme de freinage; Air base (dites [ èr bâïss ]); Formation [Formaïsheun]. All, as per normal = Comme d’habitude. « A wheel has fallen off, which was quite surreal in the circumstances… »: surreal = surréaliste, étrange, onirique. Stricken plane: l’avion n’et pas nécessairement abattu par un projectile, il peut être en perdition, touché ou endommagé pour une autre raison. On pourrait presque dire « avion en perdition » comme pour « doomed aircraft ». To devise a plan: Concevoir, inventer, imaginer, élaborer un plan. « They are spot on »: Ils sont parfaits.
Do you remember that some fighter pilots could safely eject from underwater back in 1965? Could it be survived? One may wonder but a few ejections were reported. The transcript is below the video. Look at that canopy, it looks like it came from an F-8 Crusader:
If your aircraft has provision for underwater ejection, you have a ready-made, secondary escape route. Succesful underwater ejections can be made from any aircraft attitude – nose down, tail down, and inverted.
Escape by this method requires no preparation other than that recommended for normal seat ejection. There should be at least ten feet of water above you before you can safely eject. Never eject from the surface. With present systems, the chute cannot open with a zero-zero situation (which means at a height of 0 and at a speed of 0). The effect of free-falling 80 feet to water is little different than falling 80 feet to concrete. True, some lucky ones have lived to tell about it. But it is one hell of a gamble.
When you eject through the canopy underwater, the seat breaks through clearing the way for your body. Because water resistance imposes terrific forces on your head and neck, it is vital to hold the face curtain tight against your head for support. The forces of ejection might cause a momentary blackout. Immediately upon collecting your wits, disconnect yourself from the seat by pulling the emergency release handle breaking your restraints. Now, separate yourself from the seat. This is difficult. You will have to kick and swim violently even though you are disconnected.
If your chute gets hung up on the seat, do not waste time trying to clear it. Release your riser fittings and swim clear off the chute. Do not inflate flotation equipment until clear of the seat. Remember, surface slowly, exhaling as you go. Remove your oxygen mask.
