6.4 Operational Weight and Balance Computation
An important part of preflight planning is to determine that the
aircraft is loaded so its weight and CG location are within the
allowable limits.
This is possible by using hereafter explained Loading graph
method, using weights, arms, and moment indexes.
6.4.1 Computational Procedure
1. Record into the
Airplane Loading Schedule Chart
current
empty weight and static moment of the airplane, which you read
from the table 6.2 Weight and Balance Record.
2. Record the weight of crew, fuel, and baggage into the
Airplane
Loading Schedule Chart.
3. See the
Table of Static Moments
or
Airplane Loading Graph
to read static moments for given weights of crew, fuel, and
baggage
4. Record found moments into the
Airplane Loading Schedule
Chart
5. Determine Take-off weight of the airplane
–
add together the
airplane empty weight, crew, fuel, and baggage and record the
result into the
Loading Schedule Chart
.
6. Check, whether the calculated Take-off weight does not exceed
Airplane Maximum Take-off Weight 1320 lb.
If yes, then it is necessary to reduce weight of some of the useful
load items (fuel, baggage).
WARNING
EXCEEDING MTOW MAY LEAD TO
DETERIORATION OF SAFETY OF FLIGHT!
7. Determine Total Static Moment of loaded airplane
–
add together
the static moment of empty airplane, crew, fuel, and baggage
and record the result into the
Loading Schedule Chart
.
8. Plot Takeoff Weight and Total Static Moment into the
HARMONY
LSA CG Moment Envelope
.
9. Check, whether the intersection of Take-off weight horizontal line
and Total Static Moment vertical line is inside the envelope.
If
YES
, then the flight may be safely performed as regards weight
and balance.
If
NOT
, then it is necessary to change weight of some of the
