Great! Perfect analysis! Indeed text I reported above was from Hurricane Mk.IIA-B-C-D&IV manual. My thesis is that the buzzer rang only if and when wheels were not locked and NOT always when undercarriage was up and throttle less than one-third open. Anyway, the absence of any buzzer on...

So why the plaque on the instrument panel warning about buzzer, in your opinion?

You're right! Here relevant shot from manual: Oddly enough, this warning finds no link inside manual text (which does not mention any buzzer): In any case, I wonder how could the pilot tolerate a landing pattern or a descent from, say, 20000' being plagued by this horrible sound... Thanks for...

I would like to know exactly in what circumstance did this device work; according to the label on board, it should buzz just in case the wheels are not locked down, but someone states that it screams whenever throttle is below 30% and undercarriage up. Thanks in advance.

I think so, and that it was not common practice in all air forces. Below, you may see how RAF ground crew jumps into cockpit to start engine while pilot prepares himself. https://youtu.be/zBeKGNCmvWM?si=NnmmZnPYcLY-P80d Whilst Luftwaffe follows a different procedure...

During World War II, did fighter pilots generally board their planes with the engines already warmed up by mechanics, or did they do it themselves? Did these procedures vary from one air force to another? If so, what were the practices of the major forces (Luftwaffe, RAF, USAAF, VVS)?

Thanks guys for your prompt replies. If I understood correctly, in echelon formation remain liaisons of finger four, they are just deployed in a different manner in flight. So (since I was thinking at echelons with more than four elements) each wingman should cover the odd number closer before...

I think to have understood that in the famous schwarm or finger four formation number two covered the leader and number four covered number three (or element leader). In Vic formation both wingmen covered the leader. But there was also echelon formation and I wonder in this case who covered who...

Thanks! I think your guess is right!

Thanks again!:)

Thank you so much!:) This confirmed my guess. Still just curious about meaning of right box in the picture of my first post. I attempted Google translation of what highlighted in red box of your post, getting not quite meaningful statement...:confused:: <<The large ring is designed for a target...

After eight years from when I started this thread, I got an original scheme which indicates convergence for Yak-3 guns, possibly common to other VVS fighters. It looks like the vertical convergence is set at 400 meters. It would be interesting if someone could decipher what the boxes say.

Actually, it seems that the IAR engine has a fifth power, something like "erhöhte notleistung".

Great news, thanks! According to tables on page 26 and following of the "Technical note", it looks that there are four regimes (2300 RPM @ 850 mmHg, 2100/700, 2050/650, 1950/600) plus sort of boost (2300 RPM @ 935 mmHg limited to 3' - see pg. 47 of next document). They could be respectively...

Thanks, but they are, more or less, the same contradictory figures I'm founding on the internet. Moreover, they are limited to take off (or maximum rated power). Nothing about climb and combat as well as cruising.
