An He177 equipment part to identify, please
 

Numbering starts at 930 and goes to 1040.

What is it ?? ....

Thanks , as usual

Great,

merci Nicolas.

Strange scale for an altimeter

Re: An He177 equipment part to identify, please
 

So?.....

is it some other equipment ?

Guess we do have a match here:
https://www.deutscheluftwaffe.de/fl-...barometer-1940

By the way this is a FANTASTIC site and we (members here) must give full credit to its owner...

Since the WEKUSTA 2 was active on Weather Recon...probably the WX man on board did have his own Barometer !?!?!?!?

I do agree with Snautzer...not a scale for LW altimeters (meters/Km) as shown here:

Bien vu, Adrian,

It is a scale of barometric pressure adjustment, which was part of any altimeter. When adjusted to the local pressure at the airfield the altimeter will show altitude from the airfield level. When adjusted to 1013,25 mb the altimeter will show so called standard altitude, which is used for separating higher flying aircraft safely from each others (every aircraft uses altitude indication based on the same reference level).
Same procedure is used still today with all aircraft flying in controlled airspace.

found it. Thanks Matti (it the small scale top of the meter)

Millibar (mb) = is today HectoPascal (inces of Mercury in USA - 29,92 in / 1013.25 mb at + 15 Deg C = ICAO Standard Pressure <Average>,

Standard is used for cruising, i.e. Flight Levels (ie. FL300 or above) are cruising level of todays Airliners at 29,92 in or 1013.25 mb.
Change from Local Pressure to Standard usually was about 5000 - 7000 feet, or when max deviation from normal no longer need be taken into account.
3000 feet cange used in old days resulted in accidents, because high winds blowing over mountain ranges create (often) huge deviations from true altitude.


QNH or QFE. Q code can be found in Lw flying missions reports.

CQFD Gilles

Re: An He177 equipment part to identify, please
 

Snautzer and Matti,

Bien vu! (Well see)...from the diameter yes, certainly related to the Altimeter rather to an inboard Barometer taken or used by some WX man, whilst flying...Congratulations!

hello , this is the same part from altimeter Fl22320 or 22322,Mat
