Reference AC 90-66B - Non-Towered Airport Flight Operations

Please give special attention to safe operations at non-towered airports during flight planning, student through advanced pilot training, Practical Tests, WINGS/Flight Reviews, airmen currency checks; whenever a pilot is being trained and/or evaluated by a Certified Flight Instructor (CFI), Designated Pilot Examiner (DPE), Chief Pilot, Chief Flight Instructor, Check Airman, etc.

With the safety concerns at non-towered airports (the U.S. has approximately 500 airports with control towers compared to about 20,000 non-towered airports) along with temporarily reduced hours of operation for towers across the country, this is especially timely and will serve safety now and later. Thank You!

Thank you!

Please note the updated version of AC 90-66B - Non-Towered Airport Flight Operations Change: 1 dated 02/25/2019
At some airports overflying the field and performing midfield entries to the traffic pattern is unsafe. The AWOS at Marana Regional (KAVQ) announces do not overly the field and do not fly missed approach procedures for the RNAV/GPS 12 and RNAV/GPS‐E approaches during parachute operations.
Both the RNAV/GPS 12 and RNAV/GPS‐E missed approach procedures have trajectories that pass directly through the drop zone (DZ) as can overflying and midfield pattern entries.
Please consult the Chart Supplement for more information on AVQ and nearby Pinal Airpark (MZJ) Thank You!
