Flight plan, flight following, or nothing: what to file and say
New pilots mix up the VFR flight plan and flight following constantly — they are two different things that do two different jobs. Here is which to use, and the words for each.
They are not the same thing
A VFR flight plan is a search-and-rescue safety net you file and open. Flight following is real-time traffic advisories from ATC. You can use one, both, or neither on any flight.
The VFR flight plan
You file it ahead of time, then open it with Flight Service after takeoff and close it when you land. If you forget to close it, they will start a search for you — closing it is not optional.
Flight following
You request it from approach or center in the air. They assign you a squawk code and call out nearby traffic. You cancel it when you no longer want it or are landing where they cannot follow you.
The radio call for flight following
“Approach, Cessna One Two Three Four Five, request flight following.” When they answer, give your position, altitude, and destination. Read back the squawk code they assign.
When to use which
A flight plan is the safety net for remote, mountainous, or over-water legs where a search would matter. Flight following is worth requesting almost any time you want another set of eyes on traffic. Doing both is common.
The mistake to avoid
Thinking flight following replaces closing your flight plan. They are separate systems — if you filed and opened a flight plan, you still have to close it, no matter who you were talking to.
