Why do planes veer to the left or right immediately after they take off?

Question

Commercial aircrafts do it but not military planes. Why?

Answer 1

I would venture to say a large majority of the time it is directed by atc.

Atc will normally do this to put you on course quicker allow our aircraft to climb to a higher altitude versus if it were to climb on runway heading, and to allow the expeditious flow of aircraft in the terminal environment. During slower periods of traffic, the immediate turn is predicated by a Standard Instrument Departure, (SID), a set of procedures to guide departing aircraft to their initial fixes of their filed route of flight.

Single pilot military aircraft usually prefer to climb on runway heading until reaching an altitude that will permit them to accept turns. Single-pilot aircraft are usually a bit busy in the cockpit the first few minutes after departure, adding a turn to their departure procedures only adds to the workload. So, if possible, atc will try to avoid issuing a turn with climb instructions on departure. We'll try to issue a climb, THEN a turn!

Answer 2

Just to change direction, why do helicopters immediately point a downward bank to accelerate as soon as there 2-3 ft away from the ground?

Good question though. An even better question would be as soon as fight jets leave aircraft carrier, why do they turn a little to the left or right, like the wings are heavier then the center?

Yeah they just do that to get on track asap. No need to really stay up straight going to 3kft or whatever just to turn up there.

If it's possible then it's probable. Common sense for aircraft pilots.

Answer 3

Commercial aircrafts need to follow a certain a route for departure to guide them to their destination. Therefore after take off your are guided by the ATC to turn towards your destination and head towards that direction while you climb to your cruise altitude. The second reason is because of traffic behind you waiting for take off. If you stay at the same route then they aircraft behind you who is waiting for take off will get delayed till you clear the distance required for him to depart. Military aircrafts have the airspace under their control so it wouldn't matter much for them.

Answer 4

Ok well basicly there are two diffrent types of flight

IFR
VFR

IFR- Instromental Flight rules
VFR- Visual LFlight Rules

98% of comersual jets fly using the IFR where as most of military use VFR this is sort of to do with it IFR means they will get radar servises ok and they must follow atc insutions as milatary will allways be changing there position they will use VFR they may use IFR when landing. Ok so lets say you are BA12 ok and you have just taken off there is going to be a plane behind you so he might be faster then you so to make sure you do not crash the ATC will say "speed bird 12 turn ... heading... clime and mantain ..." then the next plane will be able to take off. And there will not be a air collision.

Hope this helps

Answer 5

At GAI its to comply with established noise abatement procedures. Otherwise, if VFR, its proper to depart on downwind on a 45 at pattern altitude. Can also climb straight out on the runway heading (upwind) with a radio call.

Answer 6

Most likely this is because the ATC has told them at what altitude and direction to be traveling.

Answer 7

......... depends what your destination is ........ there is something known as standard instrument departure .. SID ...... and different routes have different SIDs ...... since runway is only in one direction, the civil plane has to turn towards the route of its destination .......... military planes have no such constrains ..... they are probably given the area for exercises ........

Answer 8

Torque of the engines, cross wind as they rice in the atmosphere and the pilots hand and foot positioning on the controls. Hydraulic responsiveness also.

Answer 9

I fly alot and i know what your talking about, I wouldnt say all of them do it. I think they are just heading in the right direction.
