How do u know if a plane is gonna reject takeoff before u have reached V1 ? That's what pilot's are paid to do is make those calls. Not all abnormal or emergency scenarios fit nieatly within the regulations. JFK has pretty generous amount of concrete to work with. This all of course depends on the amount of runway available. If the VS crew really felt that the aircraft was not going to fly for whatever reason, then it may have been the prudent thing to do. coming down in an uncontolled fireball off the end of the runway in the middle of a crowded neighborhood. Landed back on the runway and skidded off the side. Lifted off the ground in JFK and all indications were that the aircraft was not going to fly. The exception to this was demonstrated by a TWA L-1011 in the early 90's. Part 25 transport category aircraft are designed and certified to be able to safely continue the takeoff in all but the most dire of circumstances. 99.9% of the time the safest course of action is to continue. You are going and thats that - It was pointed out in the Pprune that if one were to reject the TO once rotation had started there would likely be a crash.ĭepends. Once you hit V1, call rotate and pull back on the column the nose gear comes up and you are committed. Get PhilSquares/Zeke/Wing/Pihero/CXFlyboy/PilotTaydin on here - im pretty sure they will tell you. The nosegear was up in the air for a much slower speed than their landing speed. I know this works fine with smaller aircraft (soft field takeoff and landing) and you can see that it worked with an A320 when JetBlue had that incident with the nosewheel. The aerodynamic forces over the wing will by far not be enough to support the aeroplanes weight and the aircraft would "wheelie" over the runway.
But is it not possible to ROTATE, simply get the front gear in the air at a much lower airspeed? All it needs is enough aerodynamic force over the elevator to create enough momentum to lift the front wheel. Normally you rotate at Vr which is above V1 and a commitment to go. If you read that somewhere, journalism at it's best as always. If nose wheel is up, you're at V1 already so you're going up whether you like it or not. Aborted takeoff after the nosewheel lifted" due to some dodgy altimeter indications.
