   a) Maximum landing weight plus unusable fuel in tanks.
   b) Maximum design zero fuel weight.
   c) Operational take off weight.
   d) Maximum Take off weight minus Fuel tanks capacity.

Answer 1

B

Question 2

2. Aircraft Center of Gravity (CG) is defined as
   a) A rotating point at the datum line while aircraft take off and landing.
   b) Point in an aircraft around which all weights are balanced or evenly distributed.
   c) Point in an aircraft around which all weight is not balanced.
   d) Aircraft center of gravity when empty.

Answer 2

B

Question 3

3. Dry operating index (DOI) is defined as the index figure which
   a) Corresponds to the center of gravity of dry operating weight.
   b) Equals the fuel weight index correction, plus load index.
   c) Is unique figure for each aircrafts type.
   d) Is based on aircraft engine type.

Answer 3

A

Question 4

4. When aircraft CG is near its AFT limit:
   a) Better Take-off performance is resulted i.e. higher RTOW and less Trip fuel is required.
   b) Worse Take-off performance i.e.lower RTOW and more Trip fuel is required.
   c) No effect on RTOW or Trip fuel.
   d) Datum line will move to its AFT limit.

Answer 4

A

Question 5

5. Which statement is false:
   Mean Aerodynamic Chord (MAC) is:
   a) Is the chord of a section of an imaginary aerofoil on the wing which would have force
   vectors throughout the flight range identical to these of the actual wing.
   b) It is used as a reference for locating the relative positions of the wings centre of lift and
   the aeroplane centre of gravity (CG).
   c) It is used to determine the aircraft envelope, through which the CG limit of the loading of
   each flight must be outside this envelope.
   d) The CG position, its forward and AFT limits are determined as a percentage of the MAC.

Answer 5

C

Question 6

6. Load Index Take off Weight (LITOW) is:
   a) Basic Weight Index + Fuel Index correction.
   b) Load Index Zero Fuel Weight (LIZFW) plus Fuel Index correction.
   c) Dry Operating Index (DOI) + Fuel Index Correction.
   d) Dry Operating Index (DOI) + Load Index.

Answer 6

B

Question 7

7. Datum line is defined as an imaginary reference line
   a) At or forward of the aircraft nose.
   b) On the leading edge.
   c) On the trailing edge.
   d) Which passes through the aircraft centre of Gravity (CG).

Answer 7

A

Question 8

8. Aircraft Center of Gravity (CG) must fall
   a) On a point along the length of the MAC.
   b) On a point along the length of the wing span.
   c) On a point in an aircraft around which all weight is not balanced.
   d) On a point along the length of the Longitudinal axis of the aircraft.
