Runway 29 at which point I aborted my takeoff. As I came
to a stop, I noticed that he was starting his takeoff roll. I
made an immediate 180-degree turn on the runway and
exited at the nearest taxiway…. He passed approximately
100 feet above me and about 50 feet laterally. I asked him
on the CTAF if he had seen me or heard my radio
transmissions. His response was that he had not. When I
informed him that he had created a conflict, he seemed
indignant, as though he had not done anything wrong. I
also suggested that taking off downwind was not a safe
procedure. His response was that it was his prerogative….
I believe that by choosing to takeoff downwind, he created
a potential collision conflict by opposing the prevailing
flow of traffic.
Non-Towered Airport Operations—
A Cooperative Effort
By following the FAA
recommended procedures for
operations at nontowered
airports, pilots help to ensure
that traffic flows in an orderly
and safe pattern. Aircraft without radios have to be
especially careful to adhere to published
procedures so that all aircraft in the pattern can
effectively employ the “see and be seen” concept.
For aircraft with radios, communication enhances
traffic pattern safety and involves not only
transmitting one’s intentions, but also listening
attentively. The following ASRS reports deal with
radio communication issues at nontowered
airports.
In this report, an aircraft taking off at a non-towered
airport conflicted with an aircraft landing on the opposite
runway. Among the lessons learned: a little gremlin in the
cockpit can cause a big problem.
■ I looked for activity to indicate the active runway. The
radio was quiet. Wind was calm…. Runway 5 was
downhill, out of the sun, and also in the direction of the
wind tee. I decided to use Runway 5…. I made a “…takeoff
Runway 5, north departure…” announcement on CTAF,
looked and listened for traffic, pulled onto the runway, and
Airport layout and terrain features may also be factors
that affect departures from nontowered airports. The
following report addresses a takeoff situation in which it
is imperative that pilots be especially vigilant and take
the time to ensure that other aircraft are aware of their
presence and intended action.
■ The wind was light and variable…. After broadcasting
on the UNICOM frequency that I was taking Runway 1
and departing to the north, I entered the runway and
proceeded with a normal takeoff. Just after lifting off, I
noted an aircraft on takeoff roll on the same runway, but
in the opposite direction (Runway 19). I immediately
began evasive action by turning right and continuing to
climb. The other aircraft continued a straight-ahead
takeoff. I had been monitoring the UNICOM frequency and
heard the transmissions of other aircraft, but nothing from
the aircraft on Runway 19. The primary contributing
factor to this event is that the terrain is such that aircraft
in the run-up and initial sections of both runways
(Runway 01-19) cannot see one another. Under conditions
of light and variable winds, plus light traffic, there can be
ambiguity about the runway in use, leaving it to the pilots
to communicate on UNICOM. In the event of no
transmission by one or both aircraft or simultaneous
transmissions by the aircraft about to takeoff, you have to
rely on see-and-be-seen. This can only apply when you see
the full runway, which is not always possible.
Takeoff vs. Landing
accelerated…. As the wheels got light, I saw a landing
aircraft directly opposite on Runway 23. He was rolling
out about 2,000-3,000 feet ahead of me. Since I was almost
airborne, I continued the takeoff, lifted off as soon as
possible and tracked well right of the runway. I passed the
other aircraft as it turned off the runway and radioed an
apology. There was no reply. I continued on, wondering all
the while how I missed the landing traffic. Radio switches
and indications were correct, yet I heard nothing. Then I
noticed a small toggle switch at my left knee, the speaker
“On-Off” switch that I never use. I toggled it on and heard
transmissions.
I did not expect landing traffic and I saw what I expected,
a clear path. Later I asked my three year old if he had
touched anything. “Yes,” he said, “a little switch.”
