Only operate the aircraft within the loading limits and limits for the CG location.
The current operating mass and operating CG can only be calculated by
determining the useful load for the planned flight.
To determine the operating mass and operating CG graphically and/or through
calculations, use the tables and diagrams given in the following chapters:
•
6.4.1 Mass Moments and Useful load: Loading diagram
•
6.4.2 Calculation of the proper loading for flight
Perform the following steps:
1. Take the empty mass m
Empty
and the empty mass moment M
Empty
from the
current weighing report or from the weighing logsheet. Place these values
in the corresponding columns, row 1 of the table 6.4.2 ”Calculation of the
proper loading for flight“.
2. Determine the total mass in the cockpit – including the mass of the pilot,
copilot and load carried in the cockpit. From this data, determine the
corresponding mass moments by using Diagram 6.4.1 ”Mass Moments and
useful load: Loading diagram“ or calculate the mass moments
# : . Keep the negative value of the
lever in mind, if a location is infront of the RP. Use seperate columns in row
2 for the left and right seat in table 6.4.2 ”Calculation of the proper loading
for flight“.
3. Determine the load carried in the rear baggage compartment by using the
same methods as in point 2. Place these values in the corresponding
columns of row 3 of the table. Here, the lever always has a positive value.
4. Add all masses and moments from row 1 to row 3 of the table. Place these
total values in row 4 of the table. These results represent the aircraft with
empty tanks.
5. Due to constant displacement of CG backward with retraction of landing
gear in flight, an additional constant mass moment of
152.14 ft lb / 21.04 kgm has to be considered.
6. Divide the results from row 4 (incl. constant mass moment from row 5) to
determine the lever of the operating CG in flight. This must be within the
allowed limits. If this is not the case, the useful load must be adjusted.
