[303rd-Talk] Twelve O'Clock High

[wargroom at localvertical.com]

POSITION DATA INDICATOR,

It is an instrument that in the B-17's case was (I believe) driven by the 
bombsight to keep the airplane on the correct heading towards the target.
  I believe it was a fly-to indication - meaning a deflection to the right 
means a correction to the right . The pilot was to keep it centered as best 
he could to arrive at the target after leveling out at the IP ( Initial 
point - the start of the bomb run)

    My favorite television program from 1964-1965 was Twelve O´clock High
    with Robert Lansing.
    As a pilot, he speaks to the bombardier with a throat microphone and
    says:
    "Center your PDI"

    What was the PDI?
    What was the IP?

    Thanks for any help you can provide.
