Question 35-12 : 20 kg 25 kg 15 kg 30 kg

exemple 79 20 kg.20 kg.

Choose the statement that best describes the stability concept of an aircraft ?

Question 35-13 : A stable aircraft tends to naturally resume its attitude after a disturbance a stable aircraft is very manoeuvrable and requires dynamic compensation an aircraft is stable when the forces acting on it are equal a stable aircraft is difficult to turn climb or descent

Stability is the inherent quality of an aircraft to correct for conditions that may disturb its equilibrium and to return to or to continue on the original flightpath it is primarily an aircraft design characteristic the flightpaths and attitudes an aircraft flies are limited by the aerodynamic characteristics of the aircraft its propulsion system and its structural strength these limitations indicate the maximum performance and maneuverability of the aircraft if the aircraft is to provide maximum utility it must be safely controllable to the full extent of these limits without exceeding the pilot's strength or requiring exceptional flying ability if an aircraft is to fly straight and steady along any arbitrary flightpath the forces acting on it must be in static equilibrium the reaction of any body when its equilibrium is disturbed is referred to as stability .positive static stability the initial tendency of the aircraft to return to the original state of equilibrium after being disturbed exemple 83 A stable aircraft tends to naturally resume its attitude after a disturbance.A stable aircraft tends to naturally resume its attitude after a disturbance.

The load factor on the wings may be increased anytime ?

Question 35-14 : The aircraft is subjected to maneuvers other than straight and level flight the centre of gravity cg is shifted rearward to the aft cg limit the gross weight is reduced the aircraft is turned off

In aerodynamics the maximum load factor at given bank angle is a proportion between lift and weight and has a trigonometric relationship the load factor is measured in gs acceleration of gravity a unit of force equal to the force exerted by gravity on a body at rest and indicates the force to which a body is subjected when it is accelerated any force applied to an aircraft to deflect its flight from a straight line produces a stress on its structure the amount of this force is the load factor while a course in aerodynamics is not a prerequisite for obtaining a remote pilot certificate the competent pilot should have a solid understanding of the forces that act on the aircraft the advantageous use of these forces and the operating limitations of the aircraft being flown .for example a load factor of 3 means the total load on an aircraft's structure is three times its weight since load factors are expressed in terms of gs a load factor of 3 may be spoken of as 3 gs or a load factor of 4 as 4 gs .with the structural design of aircraft planned to withstand only a certain amount of overload a knowledge of load factors has become essential for all pilots .load factors are important for two reasons .1 it is possible for a pilot to impose a dangerous overload on the aircraft structures .2 an increased load factor increases the stalling speed and makes stalls possible at seemingly safe flight speeds exemple 87 The aircraft is subjected to maneuvers other than straight and level flight.The aircraft is subjected to maneuvers other than straight and level flight.
