Definition
To keep one's hands and feet lightly hovering near, but not touching, the flight controls so that the pilot flying retains full authority while the other pilot is ready to take over instantly if needed.
Plain English
Hands and feet stay close to the controls, ready to grab them if something goes wrong, but not actually holding them while the other pilot is flying.
Context Anchor
Used during flight instruction, especially when a student is practicing a maneuver and the instructor is monitoring closely.
Derivation
From 'guard,' meaning to watch over and be ready to protect. The word implies readiness to act, not active control — a guard stands by, alert, but does not interfere unless needed.
Why Pilots Care
Maintains continuous positive control of the aircraft and prevents momentary loss of control during handovers.
Intuition Check
Do not read this as physically blocking someone from using the controls. In this context, it means staying ready near the controls so you can act quickly if needed.
Example Sentence 1
After the student took the controls, the instructor guarded the controls during the first few takeoffs in case a sudden correction was needed.
Example Sentence 2
Always guard the controls during the handover until the receiving pilot demonstrates positive control of the aircraft.
