the climbrate gauge...what does it mark?

feets/minute?

Feets/Second?

I ask this because I just was ina P47, Climbrate gauge at the "3" and in one minute I climbed 2300feet

I think its Feet per min, but im not sure.

Supposed to indicate 1000ft per minute. At 3 it should of been 3000ft per minute. It wouldn't be feet per seconds because 3 ft per second is a very slow climbrate. 3ft*60seconds= 180ft in a minute. Definitely isn't that! ;-)

EDIT: It could be 100ft per second is way to fast. And 10ft per second is still to slow. 10ft*60seconds= 600ft in a minute. 30ft*60seconds=1800ft in a minute. Hmmm that sounds possible..... <shrug> I'm all confused now.

3 = 3000 Ft Per Min. And just timed both p47's and it's accurate.

was a D30, in the Main arena.

Tried it again, at the same altitude (the time I posted this thread, I started at some 7K feet, in 1 minute climbed out to 9.3K).

This time the plane climbed to 10K from 7K in one minute.

Dunno, maybe wep kicked out and the gauge didnt move?. I did the test with clock, and I can assure that 2300 feet in one minute is what I measured.

So is it possible to get the VSI to work more like a real one? (IE based on pitot system -- pressure)

Happen to go threw a wind layer online?

Obviously some of you already know this. The Vertical Speed Indicator, or VSI, measures a change in pressure and is usually calibrated in hundreds of feet per minute. The measure of accuracy is usually no better then + or - 50ft/min

I searched the web in vain for a good site. There is alot of good information, places to test your knowledge, examples, and some bad stuff too but nothing in detail. Sorry.

hitech got a lil question for you

How would you reccomend a climb rate test be done? Should i use the autoclimb feature?
Basically what i have in mind is to do some time to climb tests for 5k 10k 20k etc.

thanks GRUNHERZ

Here is another newbie question....
Is enemy plane distance feet or is it yard?

unless there is one between 7K and 9.5K, no...and there is none.

and the second time I tested it, it gave 3K feet of climb exactly...its really weird.

I am guessing that the best way to test climb rates is to trim for various air speeds? I would like to know if the best speed varies with altitude. Is there an easy way to set airspeed or do you use manual trims somehow?

I do not want to dispute anyone but I think the VSI does not always? use the pitot tube. Without going into the differences of static pressure, case pressure, and the current bellows state; does not the vent just have to be open to outside air? Not that it matters for this line of questions.

The VSI in the Lanc is a calander.

Enemy plane distance is in yards Mitsu.

Hola RAM:

El variómetro indica pies/minuto y debería ser preciso. Prueba a efectuar un ascenso cronometrada a una altura donde no encuentres viento, que te haga variar el régimen de ascenso. Recomiendo el piloto automático, en modo ATTITUDE, u con el compensador haz un ajuste fino si es necesario.

El problema que encontrará, como en el anemómetro, es que el centro de la aguja no señala la cantidad correcta, si no uno de los extremos, por lo que puedes contar un pequeño error.

Now for Hitech.

See how wind layers prodeuce windshear, and affect climbs, as well as other phases of flight and cotrolability. Please turn Windshear off HT.

On the other hand, this post reminds me about the units in the instruments. Please, we want the original units... I am tired of using my calculator to find equivalences.

Japanese, Rusian and German instruments work with METERS and KM/H. NAVY planes work with KNOTS, and british and USAAC planes work in MILES/H. Where is the problem with including this in AH?... You did wonderfully in WB.

We want the original instruments and windshear off.
