5.
Launching occurs normally and all missile functions are norml,
xcept pitch programming, which fails completely.
In this situation the missile will travel essentially vertically
ad return to earth in the vicinity of How and Nan Island. All normal
ignals from the missile will be received by the safing and arming devices
xcept the guidance check. ‘
A dangerous detonation can occur if the warhead arms normally,
ails to fire, and fails to disarm when the disarm signal is supplied from
1e re-entry deceleration.
6, Launching occurs normally and all missile functions are normal
ccept pitch programming, which operates erratically.
In this situation, the missile will travel normally in the azimuth
rection, but pitch will be programmed erratically, hence impact with the
irth may occur anywhere along a line through How island extending in both
In this as well as in the following situation the assumption is
de that, with thrust and cutoff normal, the limits of operation of control
id guidance are such that with any possible degree of pitch the missile
11 still be at an altitude greater than 90,000 feet at the time set for ~
‘tonation.
In addition, the differences in horizontal position would be very small
and difficult to detect by ground control during the period when conmand
cutoff would be effective,
