Author Topic: Cougar throttle and WEP (Read 329 times)

I'm expecting my Cougar to arrive on Friday, and I have begun to think about how I'd like to program it. One thing I'd like to do is have WEP engage and disengage when I move the throttle into and out of the range beyond the upper detent.

My initial thought is to use CCP to define a deadband that extends from the top of the throttle range to just below the second detent. Thus, when anywhere in that range, the throttle should send 100% input to AH. I would also like the throttle to send the WEP key command ("P"?) to AH once I move beyond the second detent. I think that I can accomplish that with the following type-5 axis statement:

THR 5 2 (0 95 100) ^ (/P wep /R wep)

(I don't know whether the detent begins just after 95% yet. I am just using that number as an approximation at this point.)

The reason for the deadband is that I want WEP to be engaged once I move beyond the detent, no matter where the throttle is, and I think that AH requires a 100% input for WEP or at least an input very close to 100%. By creating a "flat" input range beyond the detent, we can "decouple" the WEP control from the throttle input (i.e., we can be at 100% throttle without engaging WEP and we can move the throttle while on the high side of the upper detent without disengaging WEP).

Does anyone have any thoughts about this or has anyone programmed a different method that works well?

Thanks in advance for you thoughts!

Take a look at this thread on Cougar World.

The way I had my AH profile was this way:

THR 5 1 (97 100) WEP

The macro for WEP in AH would be as follows:

WEP = /P p /R p

Got this from James Hallows in another thread. The throttle stil lgive full input up to the 97% mark and then engages WEP. I could'nt be bothered to open up the throttle though and move the detents which I find more useful set at 25% and 75%.

Revvin:

Thanks for the reply. It seems to me that your approach will work just fine, if you don't mind about WEP engagement/disengagement not corresponding with the detent position.

If you want some idea's or a macro file to cannibalise to save you some time you can find my AH profile here

I ended up taking WEP off the throttle axis and mapped it to the speedbrake button.

Thanks, Revvin. I looked at your profile. Nice work!

By the way, the idea I proposed earlier in this thread about deadbands won't work. In a thread on another board, James Hollows confirmed that setting up deadbands using CCP does affect throttle ranges in digital type statements. In other words, for a statement like THR 5,2 (0 95 100) ^ eng:wep, the (0 95 100) range gets mapped into the non-dead zone portion of the throttle axis.

Thanks again!

Good question and answers here. I am wanting to put the WEP on the throttle as well but I was thinking along the same lines as Revvin and using a button/switch to do it there. I intend to use the speedbrake switch for brakes on the ground and the dive brakes on some aircraft.
