Unable to Taxi, using power/collective

[flyingscotsman]

Hi I have a HOTAS and use the right thrust lever, with reverse axis as a collective, (Thrust lever in CH-47F). When trying to taxi I get no forward movement, it just starts to lift off. Even gently slowly, nothing.

I tried moving the cyclic forward or backwards, no forward or backwards movement, it wants to nose over or lift up backwards.

The brakes are OFF, so it's not that. 

What am I doing wrong?

Found it, the brakes axis is reversed, I thought as the brakes releasesd the hand brake when pressed, all was well. But then noticed the press of the pedal, got me the reverse action in the visuals. Apologies, but hope this helps someone

Also don’t lift the collective past the “ground detent” while trying to taxi. You can tell when you’ve gone too far lifting up the collective because the GND on the PFD screen will disappear. It seems like going past the ground detent kills any forward momentum you have.

You can put your throttle to FLIGHT for taxi. Just keep your stick center and raise the collective a little. Then you will move forward.

It's the Engine Condition Levers you have in flight.
You then raise the Thrust Control Lever.

Don't wanna play the smart guy here, but mixing all this terminology can confuse a lot of readers in this part of the forum.

You have to raise the Thrust Control Lever to commence rolling after releasing the brakes.
The indication in your MFD shows the status of the weight on wheels switch. If it loses contact, you start coming off the ground, which might not be what you want when intending taxi.

Just tap the toe brakes and slowly lift the collective (no cyclic!).

Not sure if this was a bug or not but in the beginning I had an issue where it would not taxi at any speed whatsoever. Even in the taxi training mission. I realized that I was releasing the brakes by clicking on the parking brake handle (which would appear to release) but the brake wasn't actually released at all. 

Then I started releasing the brakes by just pressing the pedals down fully and releasing and I never had another problem.

The parking brake can get bugged here and there. I run into this as well. Usually (but not always) it's coupled with the PARKING BRAKE ON advisory on the caution and warning display.

I have read and watched all the posts and video info on this subject, and I am still having problems trying to taxi. This is what happens:

I check brakes are OK (not wrongly inverted), Steering unlocked and on swivel,  Cyclic Trim switch on "Auto", System Select on "Both". I then release Park Brake and gently increase collective (power) remaining within ground detent. There is no forward movement except a very slow creep (it takes the Chinook about 40 seconds to travel its own length). If I increase the Power setting it stops altogether.

Can anyone please help?

Thanks,   

M.

I have the same issue.

Hovering also does not need any aft cyclic.

I might be wrong. In fact I am in danger of exposing total bollox. But I remember vaguely a chinook jockey started up and taxing still having those two control switches you are told to shut off when start up are finished and I do that together with using brakes when it act up. I can taxi with some dignity most of the time. 
BUT!!!! 
We need to remember and assume the developers know this and it is part of what we can expect being fixed.

I have the same issues! Taxing is not possible. And I find it a disgrace that, after I opened a ticket about this with ED, they wrote to me asking me to discuss it here in the forum! Helpfulness is something else!! ED shame on you!

I thought the AFCS should be off for taxi, not sure though. Agree it needs the lightest of thrust power/collective and then bit on and off the brakes to get it to roll. I also set a modifier button which I hold down and then my pedals do the swivel steering. Maybe not realistic enough for some but I don't have another axis I can use for the steering. 

Once its rolling it starts to get quicker but then it can ignore the steering so care and practice needed!

Official procedure is "AFCS off" for ground taxi, but it works with "AFCS on" though.

Had no issues with ground taxi right now...my procedure after engine start:

• both cond. levers to flight idle
• all fuel pumps on, XFER off
• GEN 1 & 2 on
• PWER XFER left/right off
• APU GEN off, APU off
• AFCS off
• steering to unlocked/swivel steering
• release parking break
• adding like 20% torque
• checking actuators in GND mode (INST page)
• GND switch/light active on MFDs

Nevertheless there are some people having trouble with ground taxi. I also checked with a buddy who has the same issues, he did everything right but he was not able to gain any forward motion...
