Land immediately/ ASAP/ as practicable
The urgency of landing is paramount. Primary consideration is to assure survival of the occupants. Landing in water, trees or other unsafe areas should be considered only as last resort.
Land without delay at the nearest adequate site at which a safe approach and landing can be made.
The landing site and duration of flight are at the discretion of the pilot. Extended flight beyond the nearest approved landing area where appropriate assistance can be expected is not recommended.
