Mass Theory Flashcards
Stall Speeds
Determined with least favourable CG position
Forward position
Minimum control speeds are determined with the CG at
The aft limit
CG outside forward limit will give a
Increase in drag
Advantage of trim tanks in horizontal stabiliser
Allows crew to keep CG at the aft position
Provide extra fuel capacity
Improved manoeuvrability
AFT CG
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
FWD CG
Higher stall speed
Decreased range
Fuel mileage vs CG
Fuel mileage decrease (Lower) with a forward CG
Fuel mileage increase (Higher) with a aft CG
Regulated Take Off Mass
Lowest of the performance limited and structural limited TOM
PLTOM > STOM = RTOM
PLTOM < STOM = RTOM
How long is a load sheet document archived for
3 months
Ops Manual CG must be
More restricted or equal to the manufacturers master flight manuals
What causes the most bending moment at wing root
High ZFM and low fuel
Maximum Running Load
The maximum load per unit of fuselage length
CG of aeroplane is situation at a distance from…
The mean aerodynamic chord in relation to the leading edge
Total Moment =
Mass x station
Add individual moments together
