Question

What is the speed needed for a commercial plane to take off?

Answer 1

a fully loaded Boeing 747 will take off at about 180 knots.

Answer 2

Lift is dependent on the weight, altitude and outside air temp (OAT). This is calculated before take of.

That or just gun it and go LOL

Answer 3

It depends on the plane.  When I was goin to Florida, they said we were going 90mph.  I thought that wasnt right.

Answer 4

Depends upon the type of aircraft, weight, winds, etc.

Answer 5

For most typical passenger aircraft that hold a minimum 110 passengers the min speed most common depending on barometric pressure, air temp, and humidity is 160mph ground speed.  At most airports take offs are done toward the wind which will lower the needed groundspeed as the airspeed driving into the plane as the plane travels forward assist in creating the lift needed to take off.

Answer 6

it varries for every different aircraft try wikipedia

Answer 7

It depends on the type of aircraft, its configuration, and its takeoff weight.
