It depends on the plane. Most planes need to be going at least 100mph to take off, some need to be traveling 150...hope this helps you.

Just like a car and a U-haul truck taking off at the same time, they need different speed...passenger plane needs certain speed depending on wind pressure and how much load/weight of the plane. I believe 100 knots is the speed needed to launch a plane off the ground.

depends on the airplane. Small single engine planes can take off at 40 mph and can land at even less, provided there is a good head wind. Larger aircraft need more distance and more speed.

It all depends on the kind of aircraft. For instance a Cessna can take off at around 70 knots. However, a 747 needs over 150 knots to get airborn.

most answers are correct so i will elaborate, air speed is the real factor more than ground speed, for this reason air craft carriers point into the wind to run flight opps, the catapults launch around 70 mph add 20 knots on ship speed and 15 knots on oncoming wind speed and your plane can now fly instead of falling into the water, this is why most air ports have 2 or three run ways going in different directions, the planes land and takeoff on the runway that is pointing into the wind (or closest to it) the added head wind allows the plane to come in slower (ground speed) for landing and take off sooner

all depends on the aircraft. the smaller and lighter the plane, the slower. Also, single engine planes have slower takeoff and landing speeds than multi engine

Depends on a lot of things. Wing span, weight of the plane, wind direction and speed.

In the case of a Harrier (as used by British forces), zero. These aeroplanes can take off and land vertically with zero horizontal speed.

As you'll have gathered, it depends on the aircraft. I can get the Cessna off at 55, an airliner might require 140 -160ish depending on load, air temperature, air density etc.

Airliner landing speed for most jets is generally 120 mph, take off is around 250 mph, cruising speed is 530 mph
