How can voltage sag mislead a pilot who relies only on the displayed battery voltage?
- A.It can trigger an early low-voltage warning during a climb even though charge remains
- B.It makes the battery appear fuller than it is during heavy climbs
- C.It has no effect on any battery indication
Correct answer
A. It can trigger an early low-voltage warning during a climb even though charge remains
Why
Because the display reflects the sagging voltage under load, a hard climb can briefly look like a nearly empty battery. Pilots should interpret warnings together with throttle demand and elapsed consumption.
