GLIDESLOPE INTERCEPT ALTITUDE
This reproduces published FAA reference text for study. It does not replace the current official FAA publication or regulation.
The published minimum altitude to intercept the glideslope in the intermediate segment of an instrument approach. Government charts use the lightning bolt symbol to identify this intercept point. This intersection is called the Precise Final Approach fix (PFAF). ATC directs a higher altitude, the resultant intercept becomes the PFAF.
