My PFD air speed display resets....

Hi

It is the only reason when the Speed tape fails.
Just check it is in FS really set to ON, may be pmSystems doesn't switch it correct in FS to ON.

Thanks Thomas - this is what I thought too yesterday, so I will load a default a/c and ensure the pitot heat and master switch is set to ON - then load the a/c I use (POSKY) and see if this fixes the problem.

Best,

Hi

Best is when you run already pmSystems to see if pmSystems logic reflects correct to the default AC and its Pitot heat switch in FS panel.

Hi

You can also limit the icing to zero in FSUIPC (no ice 0 / 1 / 2 / 3 options) - this is another work around if you don't have pmSystems or other means to control PITOT. Check the options in FSUIPC.

Hi to all,

It happened again today

I have selected icing to zero in FSUIPC (clouds tab) already. I thought that was the solution, but from the today's incident I see it was not....

Something else I noticed is that when the air speed tape resets, PMsounds stops working too !!!! I closed PMsounds just to check if that is the problem, but nothing happened.

Below 5000 ft usualy the speed tape comes back again. I suppose because of the rise of temperature, right ?

Any hint ?

Hi

It is still the same problem and nothing else than that, Pitotheat is OFF.
The reason that pmSounds suddenly doesn't give you wind sounds is that pmSounds reads as well the speed from FS and in the case that FS doesn't give any speed info (frozen Pitot) it will not give any wind sounds depending on speed, is at the moment zero(0).
Just momitor the Pitiot with FSUIPC logging in Adventure display,
0x029C , 1 Byte , Pitot Heat switch (0=off, 1=on)

So you can make sure it is really ON.

Hi Thomas,

Thanks for the reply,

I would appreciate if you could give me more info on the above.

FSUIPC / Logging tab / there is a tick box AdvDisplay indeed. What should I do after that ?

Thanks but I am not so good in programming and I am now starting to learn FSUIPC.

Hi

Pic "Log1" shows how to do in FSUIPC
Pic "Log2" shows what you will see in FS screen
The switch by side is the Pitiot switch from default B737. In the pic Log2 you see the value "1" that means the Pitot heat is ON, value "0" would show Pitot heat is OFF.
Simple than that to make sure it is in FS on, and not only a guess because of a switch or what ever.

Thanks Thomas for the hint,

I will try it this afternoon, and let you know

Thanks again,

Hi again,

Just tried and it is zero ( 0 )

SHIFT + H is the shortcut for PITOT HEAT ON/OFF in FS9

That was a great help Thomas,

I really appreciate it
