AIM ¶ 6-2-1 — Radar Service VFR Difficulty
AIM 6-2-1 explains how ATC radar assists VFR pilots in trouble, pilot responsibilities, and what to do if facing IFR conditions without an instrument rating.
AIM 6-2-1 explains the radar assistance and navigation service (vectors) that ATC can provide to VFR aircraft in difficulty, provided the pilot can communicate with the controller and the aircraft is within radar coverage.
Key points to remember:
- Radar vectors are advisory only — they do not authorize you to violate the CFRs. The pilot remains responsible for safe flight.
- Controllers may not know whether their instructions will lead you into IMC. Keep ATC informed of current and forecast weather along your route.
- Many non-instrument-rated pilots lose control when entering clouds or reduced visibility — this is why proactive communication matters.
Recommended pilot actions when in difficulty:
- If a VFR course of action exists that allows a safe landing, choose VFR over a vector or approach into IFR.
- If continued VFR is not possible and you are not instrument rated, advise the controller, state your lack of rating, and declare a distress condition.
- If you are instrument rated and current in an instrument-equipped aircraft, request an IFR clearance so assistance can be provided accordingly.
This guidance is advisory (not regulatory) but reflects best practice for pilot survival in deteriorating weather.
