Speed of an Aircraft

Speed of an aircraft noted in terms of Mach number.

1 Mach = Speed of the Sound

But the speed of the sound will change according to the atmospheric condition, For example speed of the sound at sea level atmospheric conditions is 340 km/h at 10000 m is Continue reading “Speed of an Aircraft”


Primary Control Surfaces of an Aircraft

To drive (fly) the aircraft to the desired location we need control surfaces and also to recover the aircraft from disturbed position to stable position we need stabilizers and control surfaces,

The primary control surfaces of the aircraft are:



Ailerons are placed near the edge of the wings  (the longitudinal stabilizer). Both ailerons have counter motions to say if the right aileron goes up then the left one will go down and Continue reading “Primary Control Surfaces of an Aircraft”
