 Precautionary landing 

 
A precautionary landing is generally carried out in cases where the pilot 
may be disorientated, the aircraft has no fuel reserve or possibly in bad 
weather conditions. 
 
1.  Choose landing area, determine wind direction. 
2.  Report your intention to land and the landing location. 
3.  Perform a low altitude pass into wind, over the right-hand side of 

the selected area, with flaps extended as required and thoroughly 
inspect the landing area. 

4.  Perform a circuit pattern. 
5.  Perform approach at increased idle with flaps fully extended. 
6.  Reduce power when flying over the runway threshold and touch-

down at the very beginning of the selected area. 

7.  After stopping the aircraft switch off all switches, shut off the fuel 

selector, lock the aircraft and seek assistance. 

 
 
 
 

 

 

NOTE

 

Observe the selected area steadily during 

precautionary landing.
