6.1
Introduction
This section contains the payload range within which the sailplane may be safely
operated.
A procedure for calculating the in-flight C.G. is also provided.
A comprehensive list of all equipment available for this sailplane is contained in
the maintenance manual.
6.2
Weighing procedures
See maintenance manual DG-1000S.
Datum:
Wing leading edge at the rootrib.
Reference line:
aft fuselage centre line horizontal.
The weighing is to be executed with all tanks emptied, without ballast in the
trim ballast boxes in the fin and in the cockpit (optional), but with fin battery
Z110.
6.3
Weighing record
The result of each C.G. weighing is to be entered on page 6.7. If the min.
cockpit load has changed this data is to be entered in the cockpit placard as well.
When altering the equipment, the new data can be gathered by a C.G.
calculation (see section 6.9).
The actual equipment list is enclosed in the maintenance manual.
6.4
Basic empty mass and C.G.
Actual data see page 6.7. With the empty weight C.G. and the cockpit loads in
the limits of the diagram on page 6.8, the in-flight C.G. limits will not be
exceeded.
