when deceleration reaches approximately ____ Gs. Air travel to arm is
, approximately ______ meters with the fuze being completely armed in about ____
seconds - ANSWER: WDU-4A/A. My 149 MOD 0. 17.5Gs. 11Gs. 400-600m. 1.2s

5/110, 4/90 (5, 4, 3, 2, 1.5km)
What are the ceiling considerations for an APKWS? What will an APKWS do if it does
not receive LASER energy after launch? - ANSWER: 1000' cloud clearance above
launch. Enter attitude hold and land long (up to 9km)
The photocathode in NVGs are responsive to what spectrum of energy? - ANSWER:
400-950nm. Peak at 600-900nm.
Name the BSBII FOV available in IR mode. Which ones are available in CCDTV? -

the minimum mission or transit requirements for that leg, landing at required
minimums.
Joker Fuel - ANSWER: Fuel state above Bingo at which separation, bugout or event
termination should begin.
Bingo Fuel - ANSWER: Fuel state needed for recovery either to a primary or divert
