IERW WEIght and BalancE PRactIcE Exam: QuEstIons
and ansWERs
=Where must a record be kept of the current empty weight and the current
center of gravity of an aircraft? - ANSWERIn the aircraft flight manual or
weight and balance records required by 14 CFR §23.1583.
What is meant by the datum that is used for weight and balance
computations? - ANSWERA readily identified reference chosen by the aircraft
manufacturer from which all longitudinal locations on the aircraft are
referenced.
Why are the distances of all of the items installed in an aircraft measured
from the datum when computing weight and balance? - ANSWERThis makes
it possible to find the point about which the aircraft would balance (the
center of gravity).
What are two reasons weight and balance control are important in an
aircraft? - ANSWERFor safety of flight and for most efficient performance of
the aircraft.
What is meant by moment in the computation of weight and balance? -
ANSWERA force that tends to cause rotation. It is the product of the weight
of an object in pounds and the distance of the object from the datum in
inches.
