front seat or 110 kg (242 lbs.) in the front seat and 90 kg (198 lbs.) in the rear

min. cockpit load in the front seat is the min. cockpit load see a) minus 40% of
the load in the rear seat. This means that 10 kg (22 lbs.) in the rear seat replaces
4 kg (8.8 lbs.) missing cockpit load in the front seat.
With these loads, the C.G. range given under 2.8 will be kept in the limits if the
empty weight C.G. is in its limits. see loading chart in sect. 6.
Either the front seat or the rear seat may designated as seat of the pilot in com-
mand.
If the rear seat is to be designated it must be assured that all necessary operating
items and instruments are installed and that the pilot in command has sufficient
training in flying safely from the rear seat.
Caution: With lower pilot weights lead ballast must be added to the seat.
Ballast put on the seat (lead ballast cushion) must be fastened at the
safety belt anchorage points. Installation for removable trim ballast
see sect. 7.16.1.
Note: For Australia the lower limit for the min. load in the cockpit should
not exceed 66 kg (146 lbs.). A provision for removable ballast see
sect. 7.16.1 is mandatory.
