Airspace Dialog

Dear All
May I request that in the next release the airspace query dialog only shows what is in the OpenAir file regards top and base? The last few releases have had a mixture of metres/feet/flight level. This is very difficult to interpret in the air on a dim PDA screen. If the airspace has TOP FL195, BASE 5500' I would find it much easier if that was all that was displayed. Thanks Keith |

Thirded Andy. Especially in the UK it is important that the heights are shown in the way that they are on the chart and in no other. This is because the height you need to avoid them is going to depend on the pressure setting and that is dependant on the expression of height, alt or fl.
And yes, Andy, here in Swindon it is chucking it down with a vengance. I think the next 5 to 7 days are ratsh£££t. Robin ds007a0057@... wrote: > Yes, I second that.

OK, in the next version it will not display altitude in meters unless
that is your altitude units. But it still will display altitudes for flight level airspace. Same will apply for both the airspace query dialog and the airspace warning dialog. I think the reason why meters and feet were displayed was because that code was originally programmed by a European where presumably they fly with meters but may have airspace defined in feet. Also in the next version, you can scroll the lists by touching the scrollbar. Johnny On Wed, 2008-07-09 at 12:33 +0100, robinb@... wrote: > Thirded Andy.

"But it still will display altitudes for flight level airspace." May I ask why? FL195 unambiguously means, well.. FL195. Having this also written as 19500ft just adds clutter to the screen. If it is written as 19500ft ALT then it is also wrong (except when QNH=1013). What's the rationale? Cheers Keith |

The rationale is that FL is based on QNH=1013. When your QNH is set to something else, it is useful to know what that altitude that FL corresponds to. Because otherwise you'd only be able to navigate with respect to FL by resetting the QNH to 1013..

So the flight level is automatically converted into the correct alt based on the selected QNH. Didn't know it did that. Just had a play with Sim and I now see what it does. Makes sense now. However, I've noticed that the correction is not consistent across all alts. e.g. picking a QNH at random (1000.0) gives the following FL55=5076' diff 424' FL65=6063' diff 437' FL85=8036' diff 464' FL195=18840 diff 660' Keith The rationale is that FL is based on QNH=1013.

Keith -
Atmospheric pressure does not drop off in a linear fashion as you go up in altitude. Look at a SKEW-T that's labelled in both millibars and feet (sorry for those on the metric system; I'm a dumb American)... Under standard conditions, you'll see that 900mb corresponds to roughly 3200 feet, 800mb corresponds to roughly 6500 feet, and 700mb is close to 10000 feet; the altitude differences (per 100mb) get larger as the overall pressure drops. This is also why you're above "1/2 of the atmosphere" (i.e. 500mb) above 18,000 feet - the atmosphere extends all the way out into space some 600 miles (1000km), but the air molecules are so spread out in these upper layers that if you were to count them all, you would find that over half of the molecules are crammed together down in the bottom 15000 - 20000 feet. So if you get to 1/2 pressure in only the first 15000 - 20000 feet of altitude, that leaves some 594 _miles_ (give or take a few) for the other 1/2 of the pressure gradient. Obviously that's not an even split, and it can't be a "straight line" drop-off in pressure. Although Wikipedia isn't *always* accurate, the entry on the atmosphere is pretty good. If you scroll down about 1/3rd of the way on this page, there's a section titled "Pressure and Thickness" that explains some of this really well: http://en.wikipedia.org/wiki/Earth%27s_atmosphere Take care, --Noel Wed, Jul 16, 2008 at 6:34 AM, kabmorgan <kabmorgan@...> wrote:

Keith's right on this one, due to the way that altimeters work.
We had used QNH as a static pressure offset, but in fact that's not the way they work; the altimeter setting is actually an adjustment to the reference pressure at MSL (normally 1013.25 hPa). So changing the altimeter setting is like generating a modified ISA atmosphere curve (pressure variation with height). I've just finished fixing the code. It's not committed to CVS yet. Strangely enough, it was rather hard to find definitive sources on this stuff. Various sites/documents report that a QNH adjustment will adjust the altitude by a constant amount across the troposphere, but I couldn't be sure that they weren't oversimplifying things (for pilots, ya know). So, yes, if you have a QNH which produces, say, FL50 = 5050', then FL100 should = 10100'. Seems like magic to me but that is the way the equations work out. See here: http://www.av8n.com/physics/altimetry.htm (especially the note saying "an amusing thing" near equation 16). Good spotting Keith!

Ayup
Altimeters are already calibrated taking into account the non-linear pressure gradient etc. By changing the subscale all you are doing is moving the reference point. All that happens is that the needle is mechanically shifted round a bit. This shift then stays constant regardless of the altitude. If you try to apply a further correction for the nature of the atmosphere you are doing a second, unecessary, and erroneous calibration. Cheers Keith p.s. personally I'll always stick with setting 1013. The corrected QNH way is entirely dependent on knowing the local QNH. Not always possible when 200k and 5hrs from home.

Hang on, can I just ask a question here. Johnny, are you not applying a rigid shift, are you are magnifying the change as you get higher?
I'm with Keith on this, all the altimeter does is effectively wind the atmosphere up and down with the subscale setting and this is as described in the article you quote. Making the reading equivalent to some theoretical model of the atmosphere is not what you want to do as the heights are all intended to be read by an altimeter which has the simple zeroth order mechanism as quoted in the article and so they need to match that. If however this is what you are doing and I am talking bo***cks then just ignore me - most people do :-) Robin kabmorgan@... wrote: > > Ayup > > Altimeters are already calibrated taking into account the non-linear > pressure gradient etc. By changing the subscale all you are doing is moving > the reference point.
