1
Q

True or False. An Aircraft is generally limited by structural criteria rather than Aerodynamic considerations or by the power available?

A

True.

2
Q

When an Aircraft in flight encounters a gust, the resulting load is in addition to the Aircraft’s normal weight. What is the name of this term called?

A

Load Factor.

3
Q

True or False. Load Factor can be both positive and negative?

A

True.

4
Q

When would an Aircraft experience positive load factor (2)?

A
  • Straight and Level Flight.

- Pull-up Manoeuvres.

5
Q

When would an Aircraft experience negative load factor?

A

Lift force acts in the same direction as Weight.

6
Q

What is the load factor in Straight and Level flight?

A

1g.

7
Q

Name two factors of increasing loads acting on an Aircraft in flight?

A
  • Gust Loads (Turbulence).

- Manoeuvre Loads.

8
Q

Name three factors of increasing loads acting on an Aircraft on ground?

A
  • Taxiing.
  • Takeoff.
  • Landing.
9
Q

Define Gusts?

A

Rapid change of direction and speed of the wind.

10
Q

Horizontal Gusts increase/decrease the lift by changing the speed of what?

A

Relative Airflow.

11
Q

Vertical Gusts increase/decrease the lift by changing the what?

A

Angle of Attack.

12
Q

Define Vs (2)?

A
  • Stall Speed.

- Minimum Speed in unaccelerated flight.

13
Q

Where can the Vs be located on the ASI?

A

Lower end of the green arc.

14
Q

Define Vs1?

A

Minimum Speed in unaccelerated flight in a Specified Configuration.

15
Q

Define Vs2?

A

Minimum Speed in unaccelerated flight in a Landing Configuration.

16
Q

Where can Vs2 be located on the ASI?

A

Lower end of the white arc.

17
Q

What does Vne stand for?

A

Never Exceed Speed.

18
Q

What phenomenon can occur to the Aircraft when flying close to Vne?

A

Control Surfaces may Flutter.

19
Q

True or False. Flutter can occur only at the Vne speed (2)?

A
  • False.

- Vne speed is assumed in calm air.

20
Q

What does Vno stand for?

A

Maximum Structural Cruising Speed.

21
Q

What does Va stand for?

A

Manoeuvre Speed.

22
Q

What does Vb stand for?

A

Turbulence Penetration Speed.

23
Q

When should a Pilot use Vb?

A

When flying into moderate or greater intensity of Turbulence.

24
Q

What does Vfe stand for?

A

Maximum Flaps Extended Speed.

25
Q

What does Vfo stand for?

A

Maximum Flap Operating Speed.

26
Q

Define Vlo (2)?

A
  • Maximum Landing Gear Operating Speed.

- Maximum Speed for lowering/raising the Landing Gear.

27
Q

Define Vle (2)?

A
  • Maximum Landing Gear Extended Speed.

- Maximum Speed that applies when the Landing Gear is locked down.

28
Q

What does MTOW and MLDW stand for?

A
  • Maximum Takeoff Weight.

- Maximum Landing Weight.

29
Q

Define MRW?

A
  • Maximum Ramp Weight.

- Maximum permitted weight of an Aircraft at any time.

30
Q

True or False. MRW can be higher than MTOW why (2)?

A
  • True.

- Extra taxi allowance fuel can be added to MTOW.

31
Q

Define MZFW (2)?

A
  • Maximum Zero Fuel Weight.

- Maximum Weight of an Aircraft with Zero Fuel.

32
Q

What does MFLI stand for?

A

Maximum Floor Loading Intensity.
