[NO BUG]1.5.2.49392 Su25T HUD speed indicator problem

[hannibal]

on parked before startup, the HUD IAS/speed shows the plane at 80kph one i turn on electrical power, with engines off.

 

HUD speed / IAS works normal once i start to take off, and go past 80 kph.

 

i hope this is where to report!

I've noticed the exact same thing for me too!

It's not a bug, it's a feature:smilewink:

Airspeed measurement is unreliable at low speed, so 80 is the minimum shown.

[Schmidtdude]

Is there any way to measure taxi speed then?

[hannibal]

wow.. this is new to me!

all the years i played lomac/FC/FC/FC3...

 

lol. so.. some one will tell me that there is a coca cola dispenser in the right control panel?

This is just ridiculous.

Multi million rubles planes and the pitot always reads 80 km/h?

And multi million dollars planes and they also show something other than 0 knots?

And for diferent planes the value is always the same? That assumes the Russian technology is exactly the same as western technology. It also assumes the pitots are the same in every plane.

Also, if it is unreliable, shouldn't it behave randomly? I guess it has precise unreliability, because the value is always the same. Deterministic, like we usually say.

Ridiculous.

The moment you have to think about your taxi speed, you're too fast.. at least in the real world. :)

Most planes can't read low speeds. It's not about a faulty or unreliable sensor but rather about the way it gets your speed.

If the plane would have GPS, then you could probably read your speed

Its common on most jets, Below a certain speed the Airspeed Pitots are inaccurate or dont send any readgs at all.

 

Its Not a Bug, Thread Closed.
