Ampere interrupting current (AIC) is for short circuit faults. They are meant to protect a device from _______ while trying to clear a fault.
Ampere interrupting current (AIC) is a critical rating that indicates the maximum amount of electrical current that a device, such as a circuit breaker or a fuse, can safely interrupt in the event of a short circuit fault.
A short circuit is a typical kind of electrical fault that develops when two conductors are connected in a low-resistance channel, which results in an excessive flow of electrical current.
By halting the flow of current, AIC serves to safeguard both the device and the electrical system, avoiding additional harm or risk.
Since a normal kernel mode action has a higher priority than a user mode activity during a trap interrupt, system activities are suspended. It transitions to user mode after the conclusion of the interruption.
The processor is immediately brought to attention by a hardware interrupt, which might come from peripheral devices, storage, or input/output devices.

5210-1 - To maintain a standard rate turn as the airspeed increases, the bank angle of the aircraft will need to:- remain constant-increase-decrease
In order to maintain a standard rate turn as airspeed increases, the bank angle of the aircraft will need to decrease. This is because as airspeed increases, the aircraft generates more lift and requires less bank angle to maintain a constant turn rate.
Conversely, as airspeed decreases, the aircraft generates less lift and requires more bank angle to maintain a constant turn rate. Therefore, to maintain a standard rate turn, pilots must adjust the bank angle based on the current airspeed of the aircraft.
.
A standard rate turn is a 360-degree turn completed in 2 minutes, resulting in a turn rate of 3 degrees per second. As airspeed increases, the aircraft's radius of turn also increases. To maintain the same turn rate (standard rate) while the airspeed is increasing, the bank angle must increase to compensate for the larger radius of the turn. This ensures that the aircraft continues to turn at 3 degrees per second, maintaining the standard rate of turn.
