4.7 Taxi and Run-up
During taxi do not exceed 15 km/h (10mph) which is approximately jogging speed and steer
with careful pedal input. Use wheel brake carefully, if needed, but not before throttle lever
has been completely pulled to idle. Control stick should always be maintained in forward
centre position. When taxiing on uneven ground, use particular caution and hold control
stick so as to avoid the blades or control system hitting their mechanical stops.
Carry out engine run-up in an area with least risk to individuals and other airport ground
traffic, preferably headed into the wind.
