Flight Plans, Chart Currency, Diversions and Getting Un-Lost

A VFR flight plan is optional but strongly recommended, because it triggers search and rescue if you go overdue. Remember that it is not a clearance and does nothing until you activate it: a VFR flight plan is filed with Flight Service and must be opened by radio, phone, or electronic means — it is not opened automatically. You must also close it when you arrive; an unclosed VFR plan can launch an unnecessary search. Plan on current charts: sectionals expire and are revised on a fixed cycle, and airspace, frequencies, and obstacles change, so an expired chart can hide a real hazard. When circumstances force a change, divert promptly — turn toward the new airport first, then estimate heading, distance, time, and fuel; a rough estimate made now beats a precise one made too late, and when the situation is urgent you go to the nearest suitable airport. If you become lost, hold a heading and fly the airplane, then try to fix your position from landmarks, navaids, and time flown. If still unsure, use the four Cs — climb, communicate, confess, and comply — and contact ATC or Flight Service for help rather than pressing on and burning fuel. Reserve squawk 7700 for a genuine emergency or urgent situation, or a code ATC assigns; otherwise stay on your assigned code and follow ATC instructions.
