You’re Not Authorized For That Approach

Gemini Sparkle

Key Takeaways:

  • Pilots are solely responsible for determining if an instrument approach is authorized by carefully reading all "NA" (Not Authorized) notations on approach charts, even if ATC issues a clearance.
  • Common "NA" restrictions include procedures not authorized at night (due to unlighted obstacles or insufficient lighting), limitations on circling maneuvers, specific runway landing restrictions, and Baro-VNAV temperature limitations.
  • Air Traffic Control clearances are based on known traffic and do not absolve the pilot of the responsibility to comply with all published restrictions and FAA regulations for a given approach.

turboprop-conversion Beech Bonanza crashed during an attempted night approach in IMC, killing the pilot and two passengers. Forget for a moment that the NTSB’s investigation revealed the pilot was using unapproved medications and was not even instrument-rated. Lost in the details of the accident report is that even if the pilot was IFR-rated and current, he should not have been flying that approach. Yet controllers cleared him to fly it anyway. Why should even a qualified pilot not have flown the approach? Because it was after dark, and the approach was marked “NA at night.”

As pilot in command, it’s your responsibility to determine whether an approach is authorized. It’s your job to avoid asking for an unauthorized approach, and to refuse a clearance if it includes a procedure that’s not authorized. The FAA’s guidance to controllers is to clear you for any procedure you request as long as there is no conflict with other IFR aircraft.
