Question 30

30. When would you ripple fire?

Answer 30

separate DPIs with a similar TOI. One A/C launches both and lazes the first missile; a second a/c lazes in the second. Or some HVI that we want to be sure is D.E.A.D, Dead. Or a large group that one missile isn’t enough for.

Question 31

31. Yellow on the HUD means a discrepancy between the

Answer 31

ASMS and GSMS <-just means that there is some degradation that ‘precludes normal launch’. Ref. -34 Pg. 1-4 para. 1.3.1.2.2.2
