[ARC5] AN/APR-9B and AN/APA-70C question

[zakariya.abu at yandex.com]

Hi Brooke,

Thank you for your reply.

The AGM-45 cross-needle ADI is a novelty to me.

While I thought that there must have been some sort of DF indicator eg. 
on the F-105 SEAD variants in Nam, I did not suspect it could have been 
integrated with an ADI.

Enclosed please find the pages from the F-105D flight manual, which 
depict the ARU-2B/A ADI with the said needles. The manual is from ca. 
1969/1970, and it was silent on the details on Shrike aiming and 
launching. However, it can be safely assumed that the Shrike targeting 
mode using the ADI was simply added later.

73,

Jan SP5XZG
