Arrange these steps of determining an aeroplane's centre of gravity limits:

1. Compute the neutral point from the component contributions

2. Subtract the minimum acceptable static margin to fix the aft limit

3. Assess the elevator power available at low speed

4. Fix the forward limit where the elevator can still flare the aeroplane

5. Publish the permitted range in the loading manual

Select the correct sequence.

  • A.1, 2, 4, 3, 5
  • B.1, 2, 3, 4, 5
  • C.2, 1, 3, 4, 5
  • D.1, 3, 2, 4, 5

Answer: B

The two limits arise from entirely different physics, one from stability and the other from control authority. Both must be respected throughout the flight, which is why fuel burn is considered in the loading schedule.
