  4. MCQ's for flight mechanics by priya malani


  5. CONTROLS


  6. Spoiler deflection causes? a)An increase in lift only b)Decrease in left & drag An increase in drag & decrease in lift d)An increase in lift & drag


  7. Spoiler deflection causes? a)An increase in lift only b)Decrease in left & drag clAn increase in dragn in decrease in ift


  8. ANSWERS: X Spoilers are flat panels xed to the upper surta ces of airplane wings.They are hinged in the front & can be extended into the airflow to reduce lift & increase drag.When extended into the airflow,they cause the airflow to separate & become turbulent behind the spoilers.So it reduce lift & increase drag


  9. The positive manoeuvering limit load factor for a light aeroplane in the utility category in the clean configuration is? a)4.4 b)2.5 c)3.8 d)6.0


  10. The positive manoeuvering limit load factor for a light aeroplane in the utility category in the clean configuration is? a)4.4 b)2.5 C)3.8 d)6.0


  11. hieh statement is correct for a side slip condition at constant speed & side slip angle,where the geometric dihedral of an aeroplane is increased? a)The required lateral control force increase e required lateral control force decreases c)The required lateral control force does not change d)The stick force per g decrease .


  12. ANSWERS: x The lateral stability refers to the tendency of an aircraft to roll away from sideslipThe geometric dihedral, refers to the degree to which the wings of an aircraft are angled upwards relative to its lateral axis.The purpose of geometric dihedral is to increase the lateral stability.The greater the geometric dihedral & the lateral stability,the greater will be the sideways stick force that is required to hold the aircraft in constant speed side slipping flight.


  13. ANSWERS: An adjustable horizontal stabiliser is a tailplane in which the pitch attitude can be altered in flight.This is achieved by fixing the tailplane to a pivot then using a hydraulic or electrical actuator to vary its pitch angle.This provides very powerful trimming.Thus the reason to use such system is that they provide a more powerful means of trimming
