CHAPTER 14: FLIGHT AND GROUND LIMITATIONS

Representative PPL - type questions to test your theoretical knowledge of Flight and Ground Limitations.

1.If an aircraft is fown at its design manoeuvring speed VA :

a.it is possible to subject the aircraft to a load greater than its limit load during high ‘g’ manoeuvres

b.it is not possible to exceed the limit load because the aircraft will stall before this is reached.

c.it is only possible to subject the aircraft to a load greater than its limit load during violent increases in incidence, i.e. when using excessive stick force to pull-out of a dive

d.it must be immediately slowed down if turbulence is encountered

2.VNE is:

a.the airspeed which must not be exceeded except in a dive

b.the maximum airspeed at which manoeuvres approaching the stall may be carried out

c.the maximum airspeed at which the aircraft may be fown

d.the maximum speed above which faps should not be extended

3.The maximum allowable airspeed with faps extended ( VFE ) is lower than cruising speed because:

a.faps are used only when preparing to land

b.too much drag is induced

c.faps will stall if they are deployed at too high an airspeed

d.the additional lift and drag created would overload the wing and fap structure at higher speeds

4.What is the signifcance of the speed known as VNO?

a.It is the maximum speed at which abrupt movements of the controls will result in a stall, before the aircraft’s positive load limit is exceeded

b.It is the speed beyond which structural failure of the airframe will occur

c.It signifes the upper limit of the normal operating speed range

d.It signifes the airspeed which must never be exceeded

5.The stalling speed in a turn or in the pull-out from a dive is increased because:

a.the angle of attack must be increased

b.the load factor increases

c.the aircraft’s speed increases

d.the pitch angle increases

CHAPTER 14: FLIGHT AND GROUND LIMITATIONS

6.VS is:

9.The top end of the yellow arc on the Airspeed Indicator marks:

a.the maximum manoeuvring speed

b.the maximum normal operating speed

c.the design dive speed

d.the velocity never-to-exceed

10.Above VA:

a.the aircraft may stall before the positive limit load factor has been reached

b.when the aircraft stalls, the positive limit load factor will have been exceeded

c.structural damage to the airframe is highly likely at any speed

d.the aircraft may be fown in smooth air only

CHAPTER 14: FLIGHT AND GROUND LIMITATIONS

11.The inertial forces acting on an aircraft is a function of:

a.The square of the aircraft’s indicated airspeed, its mass and the manoeuvre radius

b.The aircraft’s altitude

c.The square of the aircraft’s true airspeed, its mass and the manoeuvre radius

d.The rate of turn only

12.An aircraft’s stall speed during a positive g manoeuvre is equal to the product of its straight fight, 1g, stall speed and:

a.The square root of the load factor

b.The cosine of the angle of bank

c.The sine of the bank angle

d.The number of g pulled in the manoeuvre

13.In a steady, level turn, the load factor acting on an aircraft is equal to:

a.The indicated airspeed divided by 10, plus 7

b.The Cosine of the bank angle

c.1 divided by the Cosine of the bank angle.

d.The true airspeed multiplied by the square root of the straight fight stall speed

PRINCIPLES OF FLIGHT SYLLABUS

JAR-FCL PPL THEORETICAL KNOWLEDGE SYLLABUS

PRINCIPLES OF FLIGHT

The table below contains the principal topics and subtopics from the current outline syllabus for the theoretical examination in Principles of Flight for the Private Pilot’s Licence, as published in JAR-FCL 1.

Syllabuses may be modifed, so always check the latest examination documentation from your national civil aviation authority, or from JAR-FCL/EASA. In the United Kingdom, Principles of Flight is examined in the same paper as Aircraft (General). In this series of volumes, Aircraft (General) is covered by the section on Aeroplanes in Volume 6.

 

PRINCIPLES OF FLIGHT

The stall:

development; aeroplane characteristics at the stall; factors affecting stall

speed and aeroplane behaviour at the stall; stalling from level, climbing,

structural considerations; manoeuvring and gust envelope; limiting load

factors, with and without faps; changes in load factor in turns and pull-

manoeuvres:
