RPM gauge backwards in crewed multiplayer

[Hammer1-1]

Last night during an autorotation training session with another player, I noticed that the main rotor RPM gauge and the tail rotor RPM gauge were swapped with each other. Basically, we had to follow the little needle on the RPM gauge to gauge main rotor RPM while the large needle swayed out of bounds. https://www.dropbox.com/s/s4dnixupxlsg7sf/autorotation.rar?dl=0

Haven't watched your track, but from your description the Nr indication seems correct.

 

The dual tachometer indicates both the Nr (main rotor RPM) on the inner scale with the short needle, and the N2 (Power Turbine RPM) on the outer scale with the long needle.

 

In DCS during an auto with the engine running and the throttle at idle the N2 indicates incorrectly, it should fall to around 5400 RPM. This issue has been reported for years.

 

In DCS during an auto with the engine off the N2 indicates correctly.

 

There's no gauge for tail rotor RPM.

Now are you sure the big needle is the N2 gauge? Ive been flying the huey since day 1 and I seem to recall using the big needle for controlling disk speed in autorotations all this time. Ill double check my videos and whatnot, but I honestly think thats backwards. Whether or not it has a tail rotor indicator is kind of a moot point as thats what I was lead to believe was the small needle on the tach.

I'm sure.

 

It's even written on the face of the gauge, the inner ring has 'ROTOR' and the outer has 'ENGINE'.

 

The reason you've been using the big needle in auto is because ED/BST modelled it incorrectly. In auto the N2 shouldn't rise to match the Nr, it should fall to around 5400.

 

Next time you practice an auto, Instead of winding the throttle back to idle, shut off your fuel valve to actually shut down your engine, then you'll see the correct needle indications.

I usually click the fuel shutoff switch next to the governor. Ill give it a whirl again to confirm tomorrow, but that coincides with what I saw yesterday. When did they implement this change?

[HuggyBear]

Been like that the whole time.

 

Reported back in 2014, or maybe earlier.

Well, looks like you are correct. Guess I have to change my way of thinking in the cockpit now, so thanks for the heads up.
