Ok I’m here again to learn how to rotate properly because I always lift of the ground early I need to learn how to do smooth rotation can someone help please ?
And the term back pressure I don’t understand it at all do I hold my phone with pressure how what does it mean !
In what plane, specifically? If it’s the 747 or 787 (those planes are a nut case to get off the ground) you would want to put forward pressure on the yoke until about 150 knots, then you can rotate about 8 degrees nose high but be slow and gentle in your movements whilst tilting the device toward you.
Basically what it means, tilting the device toward you to increase the AoA and lift the plane off the ground. Hope this helps!
simbrief can caculate the Vr speed, did u check the speed?
It gave you a toga take of ? I really thought simbreif always use the flex thrust settings
It will give TO/GA or whatever full thrust is available if the runway length, or climb gradient requirements, cannot be satisfied using reduced thrust.
It means Flaps 1+F in this case. LGAV has a long runway and taking into account various factors including the weather conditions, only Flaps 1+F is needed at that weight.
That’s simply because the A380 can get off the ground with room to spare with Flaps 1+F. That runway is long enough (it can lift up to 0.8t below MTOW with Flaps 1+F in these conditions) - and the fairly hot conditions outside won’t help with climb performance either with the extra drag of Flaps 2.
There’s no rule saying that a higher flap setting must be used in all cases whenever the aircraft is heavy on most planes - those where the operator has specifically designated procedures to use higher flap settings are in the vast majority of cases due to tail clearance concerns (e.g. 777-300ER and A340-600) - which isn’t an issue on the A380.
Hi, it’s important to distinguish between smooth rotation and smooth lift off, though they are related to each other.
Smooth rotation can occur below lift off speed.
You cause rotation with back pressure when you are going fast enough for the elevator control surface deflection to take effect.
Back pressure does occur when you tilt your device toward you, but only from the calibrated and trimmed neutral postion.
If your device tilt angle starts from a tlilt angle forward (tilted away from you) from the neutral position, then tilting toward you to find the neutral postion IS NOT YET providing back pressure.
Back pressure is when you pull towards you from that neutral position.
What involves a bit of feel is that the neutral position is changing with airspeed increase.
So, in a sense, you are fishing for the exact neutral position when you tilt your device back carefully and smoothly.
Being calibrated and trimmed sets you up to more easily find that place where you are in the zone of back pressure (from the neutral point to further backwards).
And you start the smooth lift off when that smooth rotation is done at the right IAS and flaps for your given weight.
