Theory Q Flashcards
Domestic flight with 19 pax seats how is mass for passengers baggage determined
Individual weighing technique - standard masses cannot be used
What is a index
Represent a large number to simplify calculations
Non dimensional figure that is scaled down value of a moment
When must a individual aircraft be reweighed
Every 4 year period
If any modification and repairs without weighing the equipment added/removed
Or if modification change DOM by more than 0.5% or CG shifts by more than 0.5% of the MAC
When must a fleets mass be measured
Every nine years
Who is responsible for producing mass and balance documentation before each flight
The operator so the commander can determine mass and balance limits are not exceeded
What happens in the last minute changes to the load (LMC) are exceeded
If in exceed of pre determined maximum value, the new mass and balance documentation must be prepared.
AFT CG =
Decreases longitudinal static stability and reduces pitch control forces = easier stall
Reduced fuel consumption due to less trim drag
FWD CG =
More longitudinal stability
Higher control forces
More trim drag = more fuel consumption
What axis is the centre of gravity location normally computed
Longitudinal axis
Advantages of using the index method
Reduces the magnitude of moments less time consuming to compute
On very short legs with minimum take off fuel the traffic load is normally limited by
Maximum zero fuel mass
When converting volumes to masses the value of SG to be used are
Actual values or if not known those calculated in accordance with method specified and approved in ops manual
For passengers to be classified as a child they must be
Before their twelfth birthday but older than two years
