is it a bug?

[vaccaro]

Hi,
With the new client 1.1.4 I made my first flight. Everything was OK until my descend to CYVR where I was pinged for overspeeding below 10000 feet.


Not a big deal. Just wanted to make you know.

Cheers,
ARslan

Hello,

Based on the screenshot you have posted, the client 'pinged' you correctly. The 250kt speed limit applies from FL100, not Altitude 10,000 feet. As you already know, to fly at Flight Levels you need to set the standard 1013 or 29.92 pressure setting on your altimeters. You appear to have 30.53 set in that image. I work with millibars and unfortunately I don't have any conversion tables for inches of mercury to hand, but if you were to roll it down to 29.92 to show the flight level you were at, you might find you were actually below FL100.

While I am aware that the transition altitude / level is much higher in those parts (around 18,000 I believe), in most other places, including the UK and the rest of Europe, it is much lower between 3000 - 6000 on average.

Regards,

James

OK THanks.
I just wanted to make sure it is not a bug

If his altimeter was set correctly to the weather... it shouldn't have been a problem becuase you would be showing more truer information on your instuments then had you been set at 29.92

I'll bet you forgot to change the alitmeter from a previous destination, or have it set wrong for your arrival airport.

Must be something related to ASA. Because that value on altimeter made me curious and I have hit "B" several times to see if it was correct .

Hello again,

The local pressure setting has no influence on flight levels as far as this issue is concerned. No matter what the local pressure is, whether it is 998mb, 1008mb, 1024mb and so on (or the equivelent in inches of mercury), your actual flight level will always be shown with 1013 set (or 29.92), therefore there is nothing wrong with ASA as it probably did set the correct pressure, which you then set on your altimeter by pressing 'B', but the point is the 250kt limit is from FL100. Pressing 'B' to set the local pressure would not display your 'flight level' on your instrumentation (unless the local pressure happens to be 1013mb or 29.92), it would display your 'altitude' above sea level instead.

The only difference the local pressure will make will be on the transition level, which affects the minimum available flight level at which you can fly at, while the transition altitude remains constant - but that is going into too much detail and doesn't affect this issue so I will leave it there.

I hope that clears it up for you.

Arslan's guages might have been more accurate than the standard 29.92 mmHg, but FSAirlines records it from the 29.92 mmHg reading. No matter how accurate his instruments are to the real altitude, they will be wrongly detected at FL100.

I think it was ASA. Because today I have flown with good old AS6.5 and everything went perfect
