the climbing rate gauge should have HUGE variations caused by atmosphere

[raaaid]

thanks

from your link:

The K.B.B. Rate of Climb Indicator
Mark IB* is a simple means of measuring
the rate of change of atmospheric pressure
due to change in altitude of the
aircraft in which the instrument is fitted

as i predicted this scienpriests went for the obvious path

do you know what turbulences are?

sub and overpresures, they happen all the time so the climbing indicator goes crazy

the elemental way to fix this flaw is to link airspeed and angle of climb to have a precise climbing rate reading

edit:

its an edicated guess wflying really low the altitude gauge can even read negative :O

[gabuzomeu]

Absolutely,
except perhaps if IAS <>TAS and the air itself does move up and down very fast (let's say we could call this phenomenon.... wind?)

[raaaid]

oh but the vertical wind maybe a maxium of 20 kph while the horizoantal whcih measures the plane +-400 so the error is much less than with the flawed transformed barometer

You could use your radar altimeter? Might be more accurate but would be dependant on the terrain beneath you, or a GPS, or inertal navigation system, or one of those laser gyroscope dodads. It would just be a data gathering and programming issue.


Hmmmm! What did they teach in the BAK syllabus? "High to low lookout below?"

However the ASI is part of the same Pitot Static system and thus prone to the same errors

[raaaid]

well but at least you agree with me that altitude needles in the game should oscilate and the climbing rate one a lot

Was there not German method where the needles didnt jump around? - electrical gauges or something? In clod V1 the red sides needle used to jump around but the reds whined till it was fixed. Even though as you say it was realistic........... So it was there but they took it out because a vocal part of the red side didnt want that realistic factor.

pitot-static VVI´s do not oscilate a lot, but they have LAG and they are somehow sluggish.

and can you tell me how would you build a VVI gauge based on these with WWII technology???

because to get a "highly acurate" verical angle of climb/descent you need an INS or a pretty good attitude indicator and they did not have neither of these back then

on the other hand your "inquietudes científicas" generate pretty interesting posts

As a pilot I can say I haven't really noticed any wobbly oscillations of a VSI ... ever. Atmospheric pressure variances do not occur with the great horizontal or vertical rapidity that would be required to make it do so. Remember, it's just a bourdon tube with a calibrated leak.

Just totally ignore me...

I guess you guys were not there.........................................


mazex - what about that radar / command fighter thing your too busy to work on? any news?
