What is the [WARNING] associated with the 30mm?
(-10)
Failure to adhere to the published gun duty cycle may result in catastrophic failure, loss of aircraft, injury or death.
[WARNING] If ___ or more rounds have been fired in the preceding __ _______, and a stoppage occurs, personnel must ______ _____ of the aircraft for __ _______. Aircraft crewmembers should remain __ ___ ________ and ________ ________________________________.
(-10)
[WARNING] If 300 or more rounds have been fired in the preceding 10 minutes, and a stoppage occurs, personnel must remain clear of the aircraft for 30 minutes. Aircraft crewmembers should remain in the aircraft and continue positive gun control.
What is the Gun Duty Cycle IAW the -10?
6, 50 round bursts w/5 seconds between bursts followed by a 10 minute cooling period. For burst limiter settings of other than 50, no more than 300 rounds within 60 seconds before allowing the gun to cool for 10 minutes, after which the cycle can be repeated.
True / False
Under NVS, the AWS will continue to follow IHADSS LOS when operating in NVS FIXED mode
TRUE
In the event of a GUN EL MISTRACK fault, what happens to the gun?
Gun is STOWED IN ELEVTION
What happens to the gun in the event of IHADSS failure when GUN is actioned and HMD is the selected sight?
Gun firing is inhibited
When gun is de-actioned, it will return to the stowed position
In the event of a power loss, what happens to the gun? Why?
The gun is spring driven to +11 degrees in elevation.
To prevent a dig-in.
What message is displayed in the HAD when the GUN is actioned and the WP detects a ‘NO GO’ status?
What happens when the trigger is pulled?
“GUN FAIL”
