“broke their avia.

[YelenaPestereva]

Those who’ve
made mistakes usually say they got
into trouble when they “broke their
scan.” The scan is the routine way pilots
learn to watch the round gauges in
front of them and keep their bearings:
They look at the artificial horizon, then
at the airspeed, then back to the artificial
horizon, then at the altitude, then
back to the artificial horizon, then at
the heading – and back to the beginning.
That constant reference back to
the artificial horizon is necessary because
it’s the only way to know which
way is up when the natural horizon is
not visible. If some distraction in the
cockpit (maybe as minor as having to
fiddle with radio knobs) makes you
break the scan, you can easily become
very disoriented.
