Should the airlines slow down during takeoff to save gas?

Question

doesnt takeoff use alot of gas anyway

Answer 1

Yes, takeoff uses a lot of gas.  No, they should absolutely not slowdown on takeoff.  If they slowdown too much on takeoff then it will not fly like an airplane but drive on the ground like a bus.

Answer 2

Nooooooooooooo, not during TKOF, you can climb and cruise at reduced power but TKOF is done with TKOF power.

You could have a TKOF with reduced power with an empty ship and not carrying PAX's but that's the only time I could think of (and not too sure that's a good excuse) and maybe to simulate a high altitude TKOF.

Answer 3

Yes, becuase that is what it will come to.

Discount airlines are doing so well in America because they commonly pay their staff less (and hire lesser trained staff) and spend less on aircraft maintenance. They are jeopardizing safety in order to save a few bucks... which passengers clearly enjoy. I mean, if people were concerned for their safety, they would never fly on a discount carrier right?

Airlines would save millions in gas if they used less take-off power, and used the full length of the runway. Of course, if something went wrong during the take-off run, many people would die. But I mean, in the name of competition and lower ticket prices, why not take the risk?

Answer 4

how can you slow at take off, do you want the airplane to stall and crash ?? think again dude.

Answer 5

Not even possible to do so. Normal operations take off is not using all available power, 777 had a software error on the engine controller and had to do all take offs at max power (quit climb out with a light load). Full flaps creat too much drag for take off.

Answer 6

why slow down

get her there asap

Answer 7

Uhhh, they sort of need to get off the ground. And if they did, they might stall.

Answer 8

They already do. You really think they go fast and burn more kerosene for the fun of it? Pilots use the flight computer to calculate the most efficient fuel burn take off setting. It depends on the runway length, the weather and the aircraft load.

Answer 9

First of all, most people say "gas" to mean "gasoline," and most airliners nowadays are turbojet or turboprop powered, which means they use jet fuel, rather than gasoline.

Takeoffs, by definition, are made at full power, and in most cases will not be successful otherwise.  Airlines are actually engaged currently in a program of reducing power during cruise flight by a few percentage points, to save fuel.  The result is a minimal reduction in cruise speed, and a flight that is only a few minutes longer.

Answer 10

thats a great question !!! =)

Answer 11

what and fall out of the sky. wings dont work without sufficient airflow under them.

Answer 12

if you slow down you don't take off !!!!

Answer 13

It's also necessary for flight.

Answer 14

remember these quotes i have found;

the first rule of flying is;

thou shalt maintain thine airspeed lest the ground reach up and smite thee.

there are three things that are useless to pilots;

altitude above them

runway behind them

fuel in the truck.

reduced power take offs fall under the first rule. the faster you are going at takeoff, the more options you have since you have greater available lift under the wings. i wouldnt do to have a 747 drop out of the sky on some neighborhood because a pilot did use enough power on takeoff to allow for possible weather conditions, or possible mechanical problems.
