Q: Is a takeoff the phase of flight in which an aerospace vehicle or animal goes from the ground to flying in the air? ¶
Q: Is a takeoff the opposite of landing? ¶
Q: Is a takeoff also required for gliders? ¶
A: Yes, and which do not have an engine and so are unable to take off by themselves.
Q: Is a takeoff any system for helping aircraft into the air? ¶
A: Yes, The reason it might be needed is due to the aircraft's weight exceeding the normal maximum takeoff weight, insufficient power, or the available runway length may be insufficient, or a hot and high airfield, or a combination of all four factors.
Q: Is a takeoff relative to the motion of the air? ¶
A: Yes, A headwind will reduce the ground speed needed for takeoff, as there is a greater flow of air over the wings.
