Stradishall Adv Nav Trng Cse Sep-Nov '68. I remember the nigh impossible "activity" requirement for Strad-Duxford-Wyton- 53N 01E. Compass comparison, fix, alteration of heading, revised eta. The Decca fix with oggliometers whizzin' around like good 'uns due close spacing of the red,yellow,green(?). The 3 sectors couldn't have been more than a few minutes each as I recall. Hardly time to sharpen your 4H.!!
On one Airways Navex, took a shuftee at the "cloud and clonk" (CCWR) and thought I'd avert a near catastrophy by giving an immediate 60 degree alteration of course to avoid a monstrous Cu Nim. The clonk in fact was across my shoulders as the instructor used my straight-edge to emphasise that I was looking at Istres harbour as the dish was on full downwards tilt.
Quelle Plonqueur!!
