SESK: Stuff Everyone Should Know · sesk.info/pilot-flight-following-limits
With VFR radar traffic advisories, should you expect ATC to call every target?
No, not every aircraft appears or can be called.
- No, advisories are not guaranteed for all traffic ✔
- Yes, every airborne target
- Only aircraft below you
Why: Some traffic may not appear on radar, and controllers may have higher-priority duties. Keep scanning outside even while receiving flight following.
Huh, didn't know that: A pilot can tell ATC when radar advisory service is no longer desired.
Flight following is helpful, but it cannot follow every plot twist.
