anxiety. But eventually spring
arrives, better weather prevails,
and forecasts feature a more benign vocabulary. Clear.
Light and variable. High pressure. CAVU. Welcome
words signal that it’s time to relax. Up to a point. If
there are any benefits associated with flight operations
in hazardous weather, one might be that a certain
amount of “adversity” tends to sharpen one’s focus, to
bring an added level of attention to otherwise “routine”
operations. As the following ASRS reports show, clear
weather can sometimes have the opposite effect.
Both of these B737 crews were relaxed and “cruising down
easy street.” Without the need to stay alert due to weather
or traffic, they discovered that a clear, open road can lead
to complacency.
■ Beautiful day. Very relaxed; easy approach; no traffic.
On initial contact…Tower said that we could land on
Runway 2L if we had the airport in sight. Sure, we’ve got
the airport. There’s Runway 2R dead ahead, the center
field buildings, and the runway on the left. VASI (Visual
Approach Slope Indicator) has us high; nose over a little;
final flaps; on speed; on glide path. Hmm, I don’t
remember this power station on final…. On glide path; on
speed, lined up; really nice touchdown 1200 feet down the
runway. Turn off here at Taxiway T4. T4? The Airport
Diagram (10-9 page) shows T4 is on Runway 2C…. Years
of flying military and civilian and this is the first time I’ve
done this…. Ground control told us of our mistake but said
it was OK because there was no one around! Lucky for us.
Nice day. Maybe too relaxed?
■ We were climbing out on an absolutely beautiful day
with very little traffic, pretty quiet on the radio, smooth air,
enjoying the flying. We did not reset the altimeter from
30.22 to 29.92 passing through FL180. After being level at
FL290 for some time, the center controller said, “I’ve had
you 300 feet low for quite a while. Check your altimeter.”
Oops! We got complacent. It pays to remain vigilant, even
on the “easy” days.
Fair Weather Excursion
Spring fever can affect anyone’s ability to stay alert and
focused. This C172 pilot was just a little out of “sync” and
missed a clear opportunity to prevent an expensive
mishap.
■ It was a beautiful day after 22 rainy days. I went out to
enjoy the sun and upon return, I decided to make a
straight-in approach instead of a full pattern. [My]
■ Approaching for a landing, I determined the active
runway from broadcasts by a Learjet preparing to depart.
On downwind and base, I observed the Lear’s departure
and did a mental landing checklist. I did not use the
physical checklists available to me in the aircraft. I know
of no mechanical malfunction. I either skipped the landing
gear item on my checklist, or if I did check, I did not lower
the gear and confirm it. The oversight was brought to light
by the sound of the airframe impacting the runway.
The short duration flight and nice weather may have made
my attitude more casual than it should have been. The
beautiful, low sun with the Learjet departing out over the
ocean may have interrupted or distracted me from my
mental checklist…. I will always use physical checklists in
the future and triple-check gear down. I became more
involved in enjoying the view than attending to the
business at hand.
landing checklist for the C172N doesn’t say “flaps” and
because of the lack of normal pattern procedure, I landed
with only 20 degrees of flaps. I was wondering why speed
did not decrease. I floated and made a long touchdown. I
immediately applied brakes but could not stop in the
remaining runway. I ran off the runway and the airplane
sustained some damage…. I could not understand why I
was floating. I could have, and should have, gone around,
but somehow I didn’t. It was a beautiful day. I was not
mentally alert.
Visual Flight Reverie
Scenic vistas are one of the benefits of the aviation
profession, but as this pilot of a light aircraft learned,
they can also be a distraction. There is no substitute for a
physical checklist, even on the picture perfect days.
Unrestricted visibility led this MD80 Captain to believe
that everyone could see what he could see.
Visual Mindset Challenge
■ We were cleared to taxi down Runway 18R, exit at
Taxiway W6 and give way to another aircraft on Taxiway
W. As we cleared the runway…tower cleared a commuter
for takeoff from Runway 18R. I realized at that time that
