Observed Improvements
Fitment of an Airmaster AP332 propeller to the aircraft will
substantially improve aircraft performance relative to the use of a
fixed pitch propeller. General improvement will be witnessed, where
the aircraft is fitted with a Rotax 912 ULS or 912 iS engine, in relation
to:
Reference should be made to the Operators Manual for the Airmaster
AP332 Propeller operational guidelines and instructions. These should
be incorporated into the normal and emergency procedure for the
aircraft as applicable.
Improvements
1 V
h
will be increased from 116 KIAS to 120 KIAS
2 The aircraft service ceiling will increase to 14,000 ft.
3 Take-off distance on concrete and grass will improve from 120m
(395ft.) and 140m (460ft.), to 100m (328ft.) and 120m (394ft.)
respectively with the AP332 propeller.
