Why did my plane slow down after take off?

On a recent flight back from New York, the plane i was on had too bank and climb through 180 degrees too fly back too DC, during the bank and climb it seemed the plane slowed ? there was a definant change in engine noise. why did it appear too slow?|||NY area is the most crowded airspace in the world! It was the "DP" Departure Procedure that you were flying and or Air traffic control request for the airspeed reduction. Also there is a 250 knot speed limit below 10,000 feet. And on a short trip like you were on the jet ways probably way light so the power reduction was substantial.|||Perhaps there was a sudden change in wind direction|||Sooo, just because the engine throttled down you slowed down?|||Much power is needed during the 'climb out' shortly after lift-off. Once the plane levels, the pilots can reduce the speed and this is often audible to the passengers.|||It's hard to say exactly why that happened. It could have something to do with noise abatement. Some airports have sensitive areas for noise and planes have to take off and then turn to avoid those areas.


.|||On airliners, the engines are always throttled back from takeoff power to climb power at some point shortly after takeoff. Also, because there are usually maximum altitude and airspeed restrictions during the departure phase, the power is often further reduced in order to stay within these limits. This is standard operating procedure. It's more noticeable on some planes than others. Noise abatement is another possibility.|||Below 10,000 feet there is an airspeed limit of 250 knots. If your pilot raised the flaps and leveled off, he may have been approaching that limit, so he throttled back to avoid busting the FAA regs.





Or he was complying with noise restrictions, which are in place around some metropolitan airports.|||during banks the airplane will slow do to loss of inertia. it is also for the comfort of the passengers not to turn hard(its not a military fighter). it could also be from going with the wind it does not need the extra power so the pilot throttled down.|||um...maybe the change un the wind direction or maybe you were going uphill
