When did "Reheat" become "Afterburner" ?
Re #73
Anybody know if the man with the extinguisher still has a 'ringing' sound in his ears? 'Elf'n'safety, etc.
By the way, undercarriage down and locked is impossible to determine from the cockpit/flight deck! Even though there may be three greens indicated.

Confusing one for me Is LIGHT OFF call during engine start. Especially when during the start you are also monitoring warning lights that you also expect to go OFF.

Ah! You must mean the "Ration Heaters"? I remember finding a turd in one of them during an After-Flight inspection. That's about all they were fit for I reckon.
Could one utilize the Microwave Oven when operating "EMCON"....would hate for the Nav to give away the aircraft's position by heating up some Pies?

Thanks for that, Megan - an interesting piece. I would only take issue with one part (which I'm sure was an unintended "mispeaking" at the time because Ed Schmued definitely know what he was talking about!), where he says:
The energy dissipated in friction will of course be converted into heat which is included in the "30% radiated into the air" that he mentions - it can't be a separate element in this sum. I don't doubt his figure for the overall thermal efficiency (25%), but I would add the frictional losses and cylinder cooling losses together to get a ballpark number for the radiator sizing. So if it's a 1,000bhp engine I would expect the radiator and oil cooler to have to dissipate a large chunk of the 1,800bhp (~1.3MW) of heat dumped to the engine casing. Somewhere I have a piece in one of Ricardo's books which suggests that for watercooled engines like the Merlin and Sabre over half the thermal energy dissipated through the engine casing comes out as radiated heat (he was suggesting this is the only reason that aircooled engines didn't melt!), so I'd suggest that for a 1,000BHP engine the radiator and oil cooler would need to be able to dissipate at least 800BHP (~600kW) at full power - 80% of the nominal power dyno'd at the propshaft.

The distribution of power is approximately as follows: 100 percent energy in fuel is put into the engine, but about 30 percent of this has to be radiated into the air to cool the engine. Another 30 percent of the energy is lost in the exhaust heat of the engine. Then 25 percent is usually used on the propeller. This amount of power drives the airplane, overcoming the drag, so 15 percent of the fuel energy is lost in mechanical friction.

Interesting - I usually put my foot in a boot, and my bag in the trunk, but to each his own
American houses probably didn't have a boot room either
Ah, but we do leave our boots in the Mud Room.
So do we, but only on boats - and therein lies the clue. The typical american car has always had the agility, fuel-consumption and handling of a fully-laden supertanker so they feel it appropriate to apply maritime terminology to their cars...

I suppose if we had wings instead of fenders....we would have no need for mud rooms.
But how do you retain your bonnets while using wings?
