Sounds as if your (Hastings) Central Heating system would keep your "dicky" busy for the greater part of his time - indeed it's a wonder they didn't introduce a new specialty of aircrew ("Environment Master" ? - single wing with "H&C" in mixed red 'n blue wreath).
Then your faithful slave would be left free for more important tasks - like organising the Captain's coffee and bikkies, for example !
Horses for Courses - In the early days of Hastings ops AQM's (Air Quarter Masters - later ALM's Air Load Masters) made the tea to keep the captain and the rest of the crew happy and PAX as well. ISTR the AQM's station on the Hastings was a VERY small cabin on the port side behind the captains or W/Ops seat - CHUGALUG will confirm this I think.
