Airplane with 150 liter tanks should be operated from the front seat,
during the solo flight, if there is more than 100 l of fuel in the tanks.
ATTENTION:
Heavier pilot ALWAYS sits on the front seat!
Note:
The table of CG limits shown on the following pages is based on an
analysis of all permitted occupancy of the airplane in both versions = UL
and ELSA, including items that can change during the flight.
Emptying a full 100 liter tank shifts the center of gravity 1% forward.
Emptying a full 150 liter tank shifts the center of gravity 1.5% forward.
By retracting of landing gear, the center of gravity shifts between 0.5 - 1%
backward, but it does not affect the given limits.
ATTENTION:
If the airplane is fully occupied, the maximum take-off weight and CG
limit must be checked and maintained, depending on the weight of
the pilot, passenger, fuel and luggage.
If special equipment is installed, the current CG needs to be
determined by a separate calculation or by weighing the take-off
weight, including crew, fuel and special equipment. It must be within
the permitted range of 16 - 34%.
