Unit 2aa on an RT321. Had to strip the set down to a shell to do it.
Frequency illumination bulbs on an RT353.
Anything on an RT351.
Anything involving a cricket bat soldering iron usually didn’t end well.
Powering up a Ptarmigan SCRA(C) that hadn’t been used for months. Manually starting the 6.5KVA diesel genes inside Zetra Stadium in -20C temps was not my idea of fun. Nobody had ever seen it done before, let alone in that place.
What bother me though, is RAF/RN types working on aircraft in such ridiculous circumstances. Why do it in the dark/rain/snow etc, if a) it wasn’t war, and b) flight safety depends on a job well done. And what kind of poor design requires a job to be done blind? How do you know you’ve done it right?
