The preflight inspection consists of checking the aircraft for flight readiness by performing visual examinations and operational tests to discover defects and maladjustments that, if not corrected, would cause accidents or aborted missions. This inspection is conducted before each flight to ensure the integrity of the aircraft for flight and to verify proper servicing. It is valid for a period of 24 hours, provided no flight and no maintenance other than servicing occurs during this period. When all preflight requirements are contained within the daily card set, accomplishment of the daily requirements before the first flight of the day satisfies the preflight inspection requirements. - Slideshow Preflight Inspection Of The RF-4B Phantom (Currently 53 photos) Recommended Screen Resolution 1024 x 768 Enable pop-ups to fully enjoy this site.
