Advisory Circular on Nontowered Airport Operations
Airport Flight Operations
March of 2018 the FAA
released a revision to the Advisory Circular on Nontowered Airport
AC 90-66B. The revisionstandardizes traffic pattern altitudes,
of way authority for straight in final approaches and reinforces
procedures. Some pilots have not reviewed this updated AC so here are
the key takeaways from the document:
patterns altitudes at most nontowered airports are now standardized at
AC clarifies that airplanes ternating an instrument procedure with a
straight-in approach do not have the right of way over VFR
the pattern, and when circling to land, left-hand turns are standard,
unless the approach procedure explicitly states otherwise.This has been
by prior FAA legal interpretations of § 91.126(b).
any practice instrument approach, regardless of its direction relative
airport operations, does not take priority over other VFR aircraft.
should be ready to communicate on CTAF, discontinue the approach, and
traffic pattern as needed, based on the traffic saturation of the
and/or the current runway in use, to maintain aircraft separation and
a point of interest, it should be noted that the FAA does not regulate
pattern entry, only traffic pattern flow. In other words, all turns in

straight in approach.
are occasions where a pilot can choose to execute a straight-in
landing when not intending to enter the traffic pattern, such as a
approach executed as part of the termination of an instrument approach.
should clearly communicate on the CTAF and coordinate maneuvering for
execution of the landing with other traffic so as not to disrupt
the flow of
other aircraft. Pilots operating in the traffic pattern should be
