criteria listed in early access guide ATT Hold works, ALT Hold does not?

[AngryViper.101]

Hi

I can get Attitude Hold (AT) to work and it shows up on the console.
However, Altitude Hold (AL) does not appear on the console and does not appear to engage?

What parameters must I be flying for (AL) Altitude Hold to engage?

Please reference the FMC section of the DCS AH-64D Early Access Guide starting on page 186.

ALT Hold will not engage if you are pulling too much torque.  Without more info on what you were trying to do, it's hard to say what the issue was.  If the Guide doesn't help explain the parameters, post a track file and someone can take a look at what is going on.

Hi thank you!
I noticed around 50% torque (assuming you mean) collective?
when I push up the collective to around 60% + it disengages!
thanks! very new to learning the AH 64 ...

mmm does not seem to be purely a case that when my collective is 50% < that it will engage...

 

it is engaging (the ALT hold) more frequently now that I use lower collective, but does not seem to be purely related to collective %?

Of course not. Collective position within the axis has no bearing on the altitude hold engagement criteria, as described in the Early Access Guide location that I stated above.

You got to disable/enable ALT hold again. do not exceed [99] torque. try reducing it slightly and keep trying the ALT hold, you will get the "feel" for it. %.

Whenever you are heavy /light make, the % of torque will be higher /less, pay attention to the "Ground Effect vs Out of Ground Effect" and make sure you are not that heavy and not too high where the aircraft loses lift. in this case you got to fly in circles so you don't lose "lift". If you are flying at lower altitudes where the air is denser, sure, try to stabilize the " I>"  icon on the right for the altitude. then hit ALT HOLD and refrain from pulling /pushing the collective unless you need to. (for masking/un-masking) ( bob-up/bob-down)

if you want to stay in hover those are my advices, but you can test the limits later, after you get the hang of it and plan accordingly.!

 

I wish you all the best on your safe training and safe flights! have fun!
