In a 747 it feels like the plane is dropping?

shortly after takeoff in a 747 , im guessing the first 500 ft climb , it feels asif the plane is dropping , why ?|||I just got through asking why so much B.S. on this topic and here I am surrounded by it! Air pockets?.... Stalls?.... Ground effect?.... Retracting the flaps at 500 feet?......NONSENSE!!........c'mon boys and girls......stop the guessing and the B.S....the man has asked a serious question!.......as a matter of fact, people sitting in the aft part of a 747 WILL normally feel as if the airplane is dropping, because as the airplane is rotated, on takeoff, the tail section DOES drop (and the nose section RISES!)|||i agree with MR.cool , because whenever I play FSX , my 747 seems to stall shortly after take-off , the 747 is designed like this way , there's no fault of mine








thank you


alaqmar|||It is not dropping. Its climb path gets a little shallower as the flaps are retracted and as it accelerates to climb speed. The engine power is also brought back just after takeoff for noise abatement.|||after take off pilots pull up to aboutt 15-20 degrees bank and the plane has to captuer the lift just after take of and ur not just traviling forwards in the plane for split second after take off b4 the plane has the upwards lift the pland is still traviling leval to the ground even though the plane is pitched up so it feels like the plane is traviling downwards which it is in relation to the wind


hope this makes sense|||It is probably a combination of two things. Retracting the flaps shortly after takeoff can leave you with a brief sinking feeling. The most probable cause for this feeling is something called "ground effect". Ground effect makes the aircraft more efficent in regards to lift when it is within about 1 wingspan of the ground. The ground deflects the lift which makes a kind of airpocket. Pilots who take off in ground effect and do not have enough speed can stall the plane. Ground effect also has a tendency to make an aircraft float just above the runway when landing, ecspecially if their approach is too fast.|||It's when the pilots retract the flaps. You can feel this in other planes too.|||Ok... That is because the pilot is pulling the nose up to fast and the aircraft is stalling. During a stall the airplane is not going fast enough and begins to stall until it regains speed. Stalls are very common on 747s.|||Probably an air pocket. That's why they have seat belts.
