Chapter 9 - Adjusting the CG Position

Question 1

What options do we have when we need to change the CG?

Answer 1

Remove mass Add ballast Shift load

Question 2

Which way will the CG move when adding/removing a mass?

Answer 2

It will move towards the point a mass is being added or away from the point a mass is being removed.

Question 3

What is the load shift equation?

Answer 3

m = (M x c)/D

m = load being added

M = Mass of aircraft with everything in it

c = change in CG

D = Distance of movement of mass

Question 4

What is the load change equation and how is it used?

Answer 4

m = (M x c)/D

m = Mass of load added/removed

M = Mass of aircraft (Old/new (depending on New/old CG))

c = Change in CG

D = Distance between load change point and new/old CG

If you know old CG use new mass.

If you know new CG use old mass.
