One "g" is a quantity of acceleration equal to that of
earth's gravity.
Demonstrated Crosswind Velocity is the velocity of
the crosswind component for which adequate control
of the airplane during taxi, takeoff, and landing was
demonstrated during certification testing.
Demonstrated crosswind is not considered to be
limiting.
Service Ceiling is the maximum altitude at which the
aircraft at maximum weight has the capability of
climbing at a rate of 100 feet per minute.
Gallons Per Hour is the amount of fuel (in gallons)
consumed by the aircraft per hour.
Nautical Miles Per Gallon is the distance (in nautical
miles) which can be expected per gallon of fuel
consumed at a specific engine power setting and/or
flight configuration.
Unusable Fuel is the quantity of fuel that cannot be
safely used in flight.
Usable Fuel is the fuel available for flight planning.
