I'm not sure where the figure of 134 Apache pilots comes from
The maths don't add up, or do they?
Plan A. Each Attack Squadron manned with 24 Apache pilots (though the most that any one Squadron had was 19). So 24 pilots and 6 Squadrons equals 144. Add the RHQ element (times 2) that must be at least 3 each Regiment adds up to 150 pilots, then the training Squadron at Middle Wallop, IIRC should be 24 QHIs, so 174 Apache drivers if we were to be fully manned.
Plan B. Each Squadron should now be 20 pilots, 6 Squadrons equals 120 pilots, so that leaves 14 pilots/QHIs for AH Training at Wallop.
The Corps are failing in their attempt to retain AH pilots. In 2006 9 Regt had 36 LCR Apache pilots, 3 Regt had a dozen or so as did AH Training. So two years later we're up to 93. At this rate we'll never fill the manning plot.
