stowed in elevation (-10, pg. 4-106)
In the event of __________________with gun selected and the HMD as the selected sight, the gun will remain at its last commanded position. Gun firing is _____________. When the gun is de-actioned, it will ________________________________.

In the event of a power loss the gun is spring driven to _____ degrees in elevation to prevent ________ during landing.
+11; dig-in (-10 pg. 4-105)
If the gun system is actioned and the WP has detected a NO GO status, a “_____________” weapon status field message will be displayed and the _______________________ anytime ________________________________.
gun fail; LOS reticule will flash; the trigger is pulled (-10, pg. 4-22, 26; ATM, pg. 4-159)
Fixed Gun may be utilized during degraded systems operations, such as when the M-TADS or FCR are not available or unsuitable. Helmet sights are inherently inaccurate at long range due to aircraft vibration and therefore have a low probability of hit against targets beyond 1,000 meters. When engaging point targets _______________________(without the use of the M-TADS or FCR) the crew should select Fixed Gun.
beyond 1,000 meters (ATM, pg. 4-160)
When the AWS is in the Fixed Gun position, the WP will command the turret to _______ degrees in elevation and ___________ forward in azimuth to the aircraft centerline.
+.87 ; 0 degrees (ATM, pg. 4-161)
The AWS will / will not (circle one) continue to follow IHADSS LOS when operating in the NVS FIXED mode.
will (-10, pg. 4-105)
There is no indication in the cockpit when the SQUAT ORIDE switch is in the AIR position. What is the hazard associated with the SQUAT ORIDE switch being in the AIR position with the aircraft on the ground?
The possibility exists that the AWS could inadvertently be driven into the ground. (-10, pg. 4-106)
The maximum effective range of the 30mm is __________________.
1500 to 1700 meters (ATM, pg. 4-160; .45, B-15)
What is the time of flight for a 3Km 30mm shot?
12.2 sec (ATM, pg. 4-12; .45, B-17)
