Mass Theory

Question 1

Stall Speeds

Answer 1

Determined with least favourable CG position

Forward position

Question 2

Minimum control speeds are determined with the CG at

Answer 2

The aft limit

Question 3

CG outside forward limit will give a

Answer 3

Increase in drag

Question 4

Advantage of trim tanks in horizontal stabiliser

Answer 4

Allows crew to keep CG at the aft position

Provide extra fuel capacity
Improved manoeuvrability

Question 5

AFT CG

Answer 5

Increases the rate of climb and climb gradient
Decreases TODR/ASDR
MTOM increased
Less stick force required
Rotation is easier
Stall speed decreases
Range and endurance increases

• ## lower stability

Question 6

FWD CG

Answer 6

Higher stall speed
Decreased range

Question 7

Fuel mileage vs CG

Answer 7

Fuel mileage decrease (Lower) with a forward CG
Fuel mileage increase (Higher) with a aft CG

Question 8

Regulated Take Off Mass

Answer 8

Lowest of the performance limited and structural limited TOM

PLTOM > STOM = RTOM
PLTOM < STOM = RTOM

Question 9

How long is a load sheet document archived for

Answer 9

3 months

Question 10

Ops Manual CG must be

Answer 10

More restricted or equal to the manufacturers master flight manuals

Question 11

What causes the most bending moment at wing root

Answer 11

High ZFM and low fuel

Question 12

Maximum Running Load

Answer 12

The maximum load per unit of fuselage length

Question 13

CG of aeroplane is situation at a distance from…

Answer 13

The mean aerodynamic chord in relation to the leading edge

Question 14

Total Moment =

Answer 14

Mass x station

Add individual moments together
