Pattern Entry Procedures - FAA Guidance

During a recent discussion of pattern entry procedures I mentioned that I
had submitted the question to the O'Hare FSDO. After being forwarded about
five times in the FAA beauracracy, my email eventually reached Inspector
Sandra Boerman, who responded thursly:

The FAA guidance for traffic pattern entry procedures comes from the AIM,
AC 90-66A (Recommended Standard Traffic Patterns and Practices for
Aeronautical Operations at Airports without Operating Control Towers), and
14 CFR Part 91. Also, there is a video called "Operations at a Non-Towered
Airport" by AOPA that is very helpful. 14 CFR Section 91.126 does not
prohibit 45 degree pattern entries. When you are on the 45 degree entry, you
are not in the traffic pattern; therefore, a right turn to downwind is not
violating 91.126. The traffic pattern is upwind, crosswind, downwind, base
and final as defined in the AIM. 14 CFR Section 91.126 states that all turns
must be made to the left unless the airport displays approved light signals
or visual markings indicating that turns should be made to the right.

According to the above guidance a 45 degree pattern entry is the recommended
procedure for entering a traffic pattern at a non-towered airport. However,
for those pilots who choose to execute a straight-in approach, maneuvering
for and execution of the approach should be completed so as not to disrupt
the flow of arriving and departing traffic. Disruption of the flow of
traffic could be consider careless and reckless behavior.

NO FAIR Bill!!!
You know that one is prohibited from posting the facts in

This is probably true, at least as the "traffic pattern" is
defined in the AIM.

; therefore, a right turn to downwind is not
violating 91.126.

But this does not follow. 91.126 says you have to turn left
when "approaching to land," not when you're in the traffic
pattern. It sure looks like a pilot flying a 45 leg
directly towards the airport runway is "approaching" the
airport with the intent "to land."

The FSDO's comments are interesting, but certainly not
unexpected. They know that the Chief Counsel handles
interpreting the FAR's. Unless he tells them otherwise,
they can only repeat what the FAA officially recommends (45
entry) and ignore the FAR that "seems" to make that
recommendation illegal.

And, once again, the traffic pattern IS the approach at a non-towered field.

Steve, why are you posting under Todd's name?????

The traffic pattern may be "the approach," but,a gain,
that's not the language in the FAR. It's hard to say that
you're not "approaching to land" when you're less than a
mile away, your aircraft is headed directly at the runway
center, and you're following a prescribed track over the
ground that should only be followed by those intending to
land.

I just find it very hard to conclude that airplanes entering
the 45 leg are not "approaching to land," while those who've
turned parallel to the runway on downwind are. I just don't
see any good distinction. Usually, you're supposed to use
the plain words of the FAR, and give those words their most
common meaning, when interpreting the FAR. Would you argue
the same thing if the FAA did not recommend the 45? Would
you make the same distinction if these words were used in
some other FAR?

The only way out of the plain words that I see is for us or
the Chief Counsel to "interpret" the words to mean something
other than their ordinary meaning. I suspect that's what
the Chief Counsel would do if forced. I've got no problem
with that, and I certainly don't think this interesting
curiosity should prevent anyone from flying the 45. However,
to date, I'm not aware of any interpretation from the Chief
Counsel on this issue. Until there is, there's always the
chance that he'd adopt the plain meaning interpretation. I
suspect that the hot place would freeze over long before
anyone would be violated for flying the 45.

When have the facts ever settled anything around here?

Personally, I think she missed the boat. She should have said that the right
turn resulting from a 45 degree entry falls under the "otherwise authorized"
clause of the FAR.

To me, "approaching to land" means a plane on final. Otherwise you're
approaching to get into the pattern, not to land.

You fly around the pattern without intending to land? Pretty wierd.
