Why Do Airliners Rarely Use Full Thrust On Takeoff?

Simple Flying

The impressive sight, paired with the roar of engines, is due to the forces needed to lift the aircrafts weight off the ground. Despite this, an airliner will rarely use its full capabilities on takeoff as far as thrust is concerned. Wherever it is in the world, an airliners departure will typically be an impressive display of power.

How Many Horsepower Does A Commercial Jet Engine Have?

Simple Flying

Jet engines are powerful machines that are designed to generate sufficient power to lift hundreds of thousands of pounds of an aircraft off the ground and keep it airborne.

The anatomy of a commercial flight – all you ever wanted to know:   Part two   

Aerotime

Jet (and turboprop) turbine engines work more efficiently, and burn less fuel, at higher altitudes where the air is less dense. The same applies to the selecting of reverse pitch on turboprop aircraft, which translates the thrust produced by the rotating propellor forwards creating a slowing effect.

Feeling the Heat

Ask the Pilot

Workers are subject to overheating, and so is their ground equipment: all of those myriad tugs, tractors, carts and lifts that Airplanes themselves, meanwhile, have a lot of internal machinery, both electronic and mechanical, and much of it runs hot to begin with. Jet engines don’t like this low-density air either, producing less thrust.

Lift We’ll start with my personal favorite — lift. Weight Now let’s talk about the flip side of lift — weight. To maintain level flight, we would need to have enough air flowing over the wings to match the amount of weight we’re lifting — the plane itself, fuel, passengers, baggage and, of course, that cup of coffee.

During the early years of the jet age, between the end of World War II and the swinging ’60s, there were very few new ideas that were not worth a try. To understand the genesis of this little jet-powered hot rod, let’s understand the problem that faced the U.S. Air Force immediately following WWII.

Air Force and NASA to explore using vectored thrust to transition from vertical and horizontal takeoffs to achieve level flight before making a vertical landing. It was also the first VTOL aircraft to use a jet thrust diverter system for vertical lift. He compared its glide rate to that of a Cessna 206.
