Land immediately
The urgency of landing is paramount. Primary considerations is to assure survival of the occupants. Landing in water, trees or other unsafe areas should be considered only as a last resort.
Land as soon as possible
Land without delay at nearest adequate site (ie open field) at which a safe approach and landing can be made
Land as soon as practicable
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.
