5.3 Before Starting Engine
Safety is everyone’s business. Included are only some important safety tips. Keep a good lookout, be thoughtful
and always show your intentions prior to starting.
Prior to flight a thorough pre flight inspection of the ultralight should be carried out. Details of the pre flight
inspection are shown earlier in this section. Make sure all engine controls are operative and you
understand the on/off positions of the throttle and ignition. These controls are readily accessible and you
must be able to operate them instinctively without hesitation.
The primary throttle control is foot-operated and complemented by the hand throttle (rearward for full
power and forward for power off). The ignition switches are for the:
- front sit – on the bottom of the instrument dashboard (upward for on and downward for off), and for the:
- rear seat –(if it’s mounted) on the right hand side of the cockpit (forward for on and rearward for off).
