You’re Not Authorized For That Approach

Gemini Sparkle

Key Takeaways:

  • Pilots bear the sole responsibility for verifying instrument approach chart limitations ("NA" notations) and must decline unauthorized clearances, as air traffic control primarily manages traffic separation and does not relieve pilots of this duty.
  • Thoroughly read all notes on instrument approach charts to identify various restrictions, including "NA at night" for approaches or circling, Baro-VNAV temperature limitations, and specific arrival constraints, which often relate to obstacles or terrain.
  • Ignoring these critical chart notations, which define conditions under which a procedure is unsafe or unauthorized, can lead to hazardous situations or accidents.

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.
