Nobody Is Perfect?
“Nobody Was Flying”
Taking advantage of poor cockpit communication is one of
the most common ways for Nobody to take control.
Nobody’s “Got It”
Pilots Get Relief- Nobody
Takes Over
While this B757 crew was busy playing musical chairs, at
least the autopilot stayed on the job. Nobody was at the
controls.
■ During cruise flight, I needed to leave my seat and go
to the forward lavatory.... I exited the cockpit as a flight
attendant entered to secure the cockpit door behind me, per
company policy. [When I returned], I cleared the area and
knocked on the cockpit door for re-entry. Instead of the
flight attendant opening the door, I was very surprised to
see the First Officer at the cockpit door. We passed each
other as he let me in and exited to use the facility himself. I
knew instantly that nobody was “flying” the plane (of
course, the autopilot was on and we were in level flight). I
quickly jumped into my seat. Nobody was at the controls
for maybe 5-10 seconds.... In his zest to be efficient and
minimize the opening of the cockpit door (for security
reasons), the First Officer forgot he was leaving the
airplane unattended when he got up to let me in and
himself out.... To make matters worse, when the First
Officer opened the cockpit door, we were both in the
doorway at the same time in view of the first class
passengers. Additionally, since the flight attendant had
apparently retreated momentarily to the Captain’s seat to
let the First Officer get by her (the jump seat was folded
up), she may have been perceived by passengers to be “at
the controls” when the door was opened. This was an
embarrassing and misleading situation.
Nobody Busts an Altitude
This Falcon 50 crew learned that Nobody takes over when
both pilots are busy doing other things.
■ After receiving a clearance to FL280, we left our
assigned altitude. During the descent, we were doing some
HF radio checks, and forgot to arm the altitude select
mode on the flight director. As a result, we descended
through our altitude.... We promptly returned to FL280.
As a crew, we are very diligent and disciplined about
altitude assignments. But in this case, because our
attention was diverted from the task at hand, we flew
through our assigned altitude. It was that classic trap:
both crew members distracted by something and nobody
flying the airplane.
■ As I was attempting to dial in the ATIS, I was having
trouble clearing the current frequency on the radio and
[my passenger] said he would fly the airplane while I
tuned the radio. After entering the frequency, the ATIS
came on and I said, “Got it.” As I continued to listen to the
ATIS, I noticed that we had begun a shallow, descending
turn to the right. The airplane began to pick up speed and
I told [my passenger] that we were getting a little fast.
There was a stand of trees coming up quickly and I said,
■ This was a test flight and proficiency check after a
condition inspection. A pilot-rated A&P mechanic was in
the back seat (two-place, tandem). When I was finished
with the test maneuvers, I asked the other pilot if he
wanted to fly. I misunderstood him and relinquished
control. The airplane flew a random sight-seeing track, but
then descended to approximately 500 feet AGL over a golf
course. I asked the other pilot to climb. He replied that he
thought I was flying. Nobody was flying.
In this report, Nobody did a little sight-seeing and then
headed for the golf course... with two pilots along for the
ride.
“We need to pull up.” He pulled the plane out of the
shallow dive.... We had a long discussion afterward and it
was clear that he misunderstood “got it” to mean that I
had control of the airplane. We each thought that the other
was flying when actually nobody was flying the plane. We
agreed that we would be more certain of cockpit
communications in the future.
Reports to ASRS often confirm the popular wisdom,
“Nobody is perfect.” However, in the following
reports it would appear that “Nobody” is not
perfect. Things can go wrong when Nobody takes
over.
