Environmental factors-

Temperature variations have important bearings on the design of the engine cooling system. Low temperature can cause such problems as icing thecarburators of aircraft engines. High temperature on the other hand reduce the structural strength of materials. Many electronic components do not work satisfactorily in temperature 60 degree celcius.
Vibration levels and accelerations have adverse effects on almost all systems. Vibration introduces a serious problem in aircraft structures because of fatigue.
