Outside Air Temperature

[Ebodee]

So yeah, outside air temperature. I am departing up a valley ascending toward snowcaps when I get an EKRAN reminder to turn on my rotor anti-ice. Well, ok, I think I will also engage my engine anti-ice as well without verifying it is already on when I hear the all familiar sound of both my engines spooling down and rotor RPM slowing... I suppose dust protection is not as useful in temperatures below freezing.

 

Other than via the FPL in EBRIS which is an indirect measurement and inference of the temperature, is there any other method inside the office to directly measure the Outside Air Temperature (OAT)?

I suppose Opening the Cockpit Door and Sticking your Head out does'nt Count?

 

:P

Failing that, try the finger.

Look at the engine oil temps prior to startup. ;)

FPL button on the ABRIS will show temps at each waypoint. It is part of every startup routine for me.

 

If you need rotor anti-ice, you need the engine anti-ice screens, and, as you learned when it is too late, you are too late :)

 

I turn on rotor and engine anti-ice when temps are single digit. Pitot heat is always on as is the INS anti-ice.

Usually do that or look at xm box temps but bit hard to do when loading into an already started bird.

I believe that the INS heat serves not keeping the INU from freezing, but to speed up alignment when the oil is cold, at least that's how i remember somebody explaining it.

There's an outside (well, similar to Mi-8's and Mi-24's) thermometer on the cockpit ceiling, however it is not simulated. I think it should be. Does ABRIS show temps according to its FPL? If so, if I deviate from plan, either in coordinates or altitude (!), this pure thermometer would be useful. IRL, in late autumn, winter and early spring, we often take a look on it as we change altitude by hundreds of meters.

 

Cheers!

Ooooooohhhhhh so that's what it was... I was soo puzzled by a non-moving dial on my ceiling... too bad it's not simulated, it's really missing.

I always work on the basis that you lose about 2 degrees C for every 1,000ft when in Western aircraft and 6 degrees C for every 1,000m in Russian.

 

Naturally the actual lapse rate isn't 2 and 6 but this makes it easier to calculate for the rule of thumb, and sure as hell is close enough for the purposes of this sim.

 

Also I was taught to switch the Pitot Heat on whenever you are in rain and always at 10 degrees C or below.

 

You can work out the freezing level easily enough at the start of the mission with those two rules of thumb :)

I agree, it would be very nice to see that modeled, as it is something that can save your butt against icing in the mountains.

I'll put my hand up too... I've always though it was a bit odd that there was no external temp indicator... :cry: I love my KA-50 and it don't talk to me :cry:
