4.33.4 Point Target Weapons System.
WARNING
When firing Hellfire missile AGM–114A at
temperatures below –10 C, severe ice
fog can be formed by the missile exhaust
plume. The ice fog can obscure crew vis-
ibility and also interfere with autono-
mous designation.
1. MSL switch – ON, observe BIT IN PROGRESS
message on high action display and AND. When
message disappears any failed BIT status will
be displayed on AND.
NOTE
If BIT failure indicates MSL failure, and
that missile is required to complete the
mission, another BIT cycle may be initi-
ated. If additional BIT indicates a go, then
missile is considered functional and may
be launched. If missile fails second Built–
In–Test (BIT) then missiles shall be re-
jected.
BIT may be overridden at any time by
placing the MSL MODE switch in any
mode other than STBY.
