AIM ¶ 5-5-3 — Contact Approach
Master the AIM 5-5-3 contact approach: pilot requests, 1-mile visibility, clear of clouds, and ATC separation rules for IFR checkride prep.
A contact approach is an IFR procedure a pilot can use in lieu of a standard or special instrument approach when weather is below VFR but the pilot can navigate visually to the destination. Per AIM 5-5-3, this approach is pilot-initiated — ATC will never offer it; you must request it.
To request and fly a contact approach, you must:
- Be operating clear of clouds
- Have at least 1 statute mile flight visibility
- Reasonably expect to continue to the destination in those conditions
- Accept responsibility for obstruction clearance
- Notify ATC immediately if you cannot continue or visibility drops below 1 mile
The controller will only issue the clearance if reported ground visibility at the destination is at least 1 mile, and will provide IFR separation — typically vertical separation at least 1,000 feet below other IFR traffic, but never below the minimum safe altitudes of 14 CFR 91.119. ATC may issue alternative instructions if weather makes the approach impracticable. Also, radar service may automatically terminate when told to contact the tower.
