Q4
The DLL of a transport aircraft is
- A 1.5g
- B 2.5g
- C 3.4g
- D 3.75g
Show answer
Correct answer: B. 2.5g
The design limit load for a large transport aircraft is 2.5g, the maximum manoeuvring load factor the structure must withstand without permanent deformation, above which structural yielding could begin.
-

- A 2.0, 1.5.
- B 2.5, 2.0.
- C 2.0, 2.5.
- D 2.5, 2.5.
Show answer
Correct answer: B. 2.5, 2.0.

- A The aircraft will suffer permanent damage.
- B The aircraft cannot be damaged by control inputs.
- C The aircraft cannot be stalled before exceeding the limiting load factor.
- D Manoeuvring is not possible.
Show answer
Correct answer: B. The aircraft cannot be damaged by control inputs.

Q7
If load factor is increased beyond.. . . .. at maximum operating altitude it will cause.. .. . . . . . . . ?
- A lg, mach tuck under.
- B 1.3g, buffeting.
- C 1.5g, clear air turbulence.
- D 2.5g, overstressing of the structure.

Q8
VA is?
- A Minimum speed a t which maximum nose up control input is permitted.
- B Maximum speed at which full nose up control input is permitted.
- C Minimum control speed.
- D Maximum control speed
Show answer
Correct answer: B. Maximum speed at which full nose up control input is permitted.

Q9
In level flight, since lift equals weight, if the aircraft is performing a manoeuvre such that, twice the weight, the load factor will be:
- A 1.5
- B 4.0
- C 2.0
Show answer
Correct answer: C. 2.0
Load factor is lift divided by weight, so a manoeuvre demanding lift equal to twice the weight gives a load factor of 2.0, that is, 2 g.

- A Increased aspect ratio.
- B Increased camber.
- C Increased wing area.
- D Increased sweep back.
Show answer
Correct answer: D. Increased sweep back.

Q11
Which of the following would improve ride quality in turbulence?
- A Increased aspect ratio.
- B Increased camber.
- C Increased wing area.
- D Increased sweep back.
Show answer
Correct answer: D. Increased sweep back.

Q12
VA is?
- A The minimum speed at which it possible to attain limiting positive load factor.
- B The maximum speed at which it is possible to attain limiting positive load factor.
- C The recommended rough air flying speed.
- D The maximum operating speed.
Show answer
Correct answer: A. The minimum speed at which it possible to attain limiting positive load factor.
