9.1.7
Placards
There are no placards associated with the constant speed controller, noting that the engine
rpm limits are engraved on the instrument panel under the propeller controller (which
displays engine rpm).
9.1.8
Manifold Absolute Pressure Indications
The analogue manifold absolute pressure gauge (MAP) has perimeter markings to show
normal, warning and limit values in the conventional colours
9.1.9
Circuit protection
The propeller controller is supplied from the propeller power supply (C/B F5 16A). Manually
pulling this circuit breaker (to the “off” condition) will result in loss of controller display
together with the propeller remaining at its last pitch setting. Continued flight should be
made expeditiously (see 9.1.13 Coping with Malfunctions)
9.1.10
Pilot Training & Experience
These notes assume that the pilot already has some experience of operating a variable
pitch propeller. The UK CAA strongly recommend pilots to undergo ’differences training’
before they are allowed to operate aircraft with variable pitch propellers.
