Definition
A grouping of recurring instrument-flight mistakes pilots make when entering, holding, or rolling out of a turn while flying solely by reference to instruments. Typical errors include applying excessive or insufficient bank, failing to cross-check the attitude indicator with the turn coordinator and heading indicator, allowing pitch and altitude to change during the bank, using improper rudder coordination, fixating on a single instrument, and rolling out late or early on the desired heading.
Plain English
The set of mistakes pilots commonly make when turning the airplane using instruments instead of looking outside. Things like banking too steeply, losing altitude in the turn, staring at one instrument, or finishing the turn on the wrong heading.
Context Anchor
Seen in instrument training when learning how to make accurate turns using the flight instruments instead of outside visual references.
Why Pilots Care
Identifying these errors prevents loss of control, disorientation, or altitude busts during IFR flight.
Intuition Check
Do not read “common errors” as minor style preferences. In this context, they are control or instrument-use mistakes that can make the aircraft leave the intended heading, altitude, speed, or turn rate.
Example Sentence 1
During the debrief, the instructor reviewed the common errors in turns and pointed out that the student had been losing 100 feet every time he rolled into a 30-degree bank.
Example Sentence 2
Recognizing common errors in turns helped the pilot maintain altitude during the IFR lesson.
