STANDARD WEIGHT OF GASOLINE
6 LBS PER GALLON
BASIC EMPTY WEIGHT
UNUSEABLE FUEL AND UNDRAINABLE OIL
CG
TOTAL MOMENT DIVIDED BY TOTAL WEIGHT
DATUM
VERTICAL PLANE IN AIRCRAFT FROM WHICH WEIGHT AND BALANCE DISTANCES ARE MEASURED
ARM
THE DISTANCE FROM A DATUM OF A PARTICULAR STATION OR PLACE IN THE AIRCRAFT
CALCULATE MOMENT
WEIGHT OF STATION X WEIGHT OF ARM
AFT OF DATUM CG VALUES ARE
POSITIVE
FORWARD OF CG VALUES ARE
NEGATIVE
WEIGHT SHIFT FORMULA
WGT MOVED / WGT OF AIRPLANE =
DIST BETWEEN ARMS
WHICH ARE ITEMS INCLUDED IN THE EMPTY WEIGHT OF AN AIRCRAFT
A- UNUSEABLE FUEL AND UNDRAINABLE OIL
AN AIRCRAFT IS LOADED 110 LBS OVER THE MAX CERTIFIED GROSS WGT. IF FUEL ( GAS) IS DRAINED TO BRING THE AIRCRAFT WEIGHT WITHIN LIMITS, HOW MUCH FUEL SHOULD BE DRAINED?
C-
- CONVERT WGT OF FUEL TO GALLONS
- DIVIDE 110 LBS BY 6 LBS/GAL= 18.3 (CLOSE ENOUGH)
