technique is for safety reasons as engines are susceptible to stopping, no matter how reliably 
manufactured or maintained. 

Keep a good lookout for other ultralight, always be thoughtful and show your intentions.  

Remember that the manufacturer cannot foresee all conceivable circumstances. Particular circumstances 

such as multiple or unanticipated emergencies, adverse weather etc may require modification to these 
procedures. A thorough knowledge of the ultralight and its systems is required to analyze the situation 

correctly and to determine the best course of action. 

 
Maximum maneuvering speed is 70 km/h. 

Best glide speed (with maximum load) is 50 km/h.

 

 

9.2 Engine Failure on Take Off 

 

10.2.1 Engine Failure on Take Off Run 

If the engine fails on take off run before the ultralight has lifted off proceed as follows: 
- pull the control bar in to prevent the ultralight lifting from the ground; 

- use pedals to maintain the ground run direction, avoid direct collision with obstacles; 

- switch off the ignition.  
 

10.2.2 Engine Failure on Climb Out 

If your engine fails on climb out before you have reached 5 meters altitude, land straight ahead. Proceed 

as follows: 
- pull the control bar in further than the trim position to prevent the ultralight from loosing airspeed; 

- Land in accordance with section 6.7 of the Manual. Avoid direct collision with obstacles. 

- switch the ignition off. 
 

9.3 Engine Failure at Height 

 
If the engine stops while operating at cruise or full power when the ultralight is well clear of the ground, 

make sure that ignition is on. 

If your engine fails in flight, do not attempt to restart the engine unless one of these items is found to be 

incorrect and is able to be rectified. Relax and maintain control whilst concentrating on correct forced 
landing techniques. 

 

9.4 Full Power Engine Shutdown (In Flight) 

 

If the throttle should jam full open in flight proceed as follows: 

Maintain Control. 
Get height with engine at full power, adjust height and ground position to improve the outcome of 

forced landing. 

Increase airspeed to keep the climb angle less than 30 degrees above the horizontal. 

Switch off ignition. 
Prepare for forced landing, section 9.5. 

 

9.5 Forced Landing 

 

Proceed as follows: 

Maintain control and airspeed - nominated approach speed. 
Close the throttle. 

Switch the ignition off. 

Tighten the seat belts.  

Carry out final approach and landing as closely as possible to normal power off landing procedure. 
 

9.6 In Air Engine Fire 

 
For fire occurring whilst in flight, the initial procedure would be to maintain control of the ultralight and 

evaluate the extent of the fire. This emergency is unlikely to occur but to avoid any further problems, use 

common sense and land the ultralight safely. Proceed as follows:
