Altitude hold - not working anymore

[Goa]

Hi,

 

is it the altitue hold bugged with the latest open beta patch or am I having problems?

It looks to me that after I bind a switch on my TM warthog throtle for both AFC and altitude hold now only AFC is working.

I unbind the altitude and set it to default which is H but the altitude hold autopilot does not engage anymore nor the switch in the cockpit is moving, even if I click it with the mouse it doesnt move....

I run cleanup and repair but the problem is still there, the altitude hold switch does not engage....

Could someone please check whether its working or not?

 

 

Thanks in advance:thumbup:

Hi Goa,

 

It is working for me and I have both bound to buttons on my X55 throttle :thumbup:

"The AFC switch must be engaged with the INS switch in NAV or IFA in order to engage the ALT HOLD switch."

 

It works at my end, on 2.5.2*

it is so strange, I've runned a repair and a cleanup, now both altitude and AFC are set to default key binding A and H but the altitude hold does nothing....even if I click it with the mouse.....

THE AFC is working, it is the altitude HOLD whid does nothing, I click on it but it doesnt move, it remains in off position.

I move the swith to NAV as alwys ;)

Yeah I just threw the manual quote in there in-case of an INS switch oversight or other. I think others have had binds issues too, I recall reading a hackish fix of removing the binds to default and then rebinding them, YMMV.

I solved it, AFC must be on otherwise altitude hold is not working, furthermore altiude hold will engage only if properly trimmed.

Not so much trim, though that'll certainly help, here's a relevant part of the Flight Manual;

 

2.16.2.2 AFC Mode -- AFC and ALT HOLD Switches Engaged

 

The ALT HOLD switch permits selection of altitude hold in place pitch attitude hold in the AFC mode. The AFC switch must be engaged in order for the ALT HOLD switch to be engaged. In addition, the airspeed must be greater than 160 knots and the climb or descent rate must be less than 2,000 feet per minute for the ALT HOLD switch to be engaged. Altitude hold may be manually disengaged by “clicking” the pitch manual trim button as well as by turning the panel switch off. The operation of the roll attitude hold, heading hold and automatic pitch and roll trim is identical that with the AFC switch only engaged. If either the pitch attitude limits of ±30° or the roll attitude limits of ±60° are exceeded, the ALT HOLD switch will be disengaged and reversion to the AFC mode without altitude hold will occur. The ALT HOLD and AFC switches will also disengage if the displayed AOA exceeds +16° ±1°. Altitude hold is also monitored by logic which will disengage the ALT HOLD switch and revert to AFC without altitude hold if any of the following events occur:

1. The altitude hold does not lock on to an altitude reference within ±250 feet following manual engagement of the trim switch or following interruption of altitude hold by longitudinal stick forces exceeding 1 pound. An altitude reference is established when the altitude rate is driven below 500 feet per minute by the altitude hold synchronization.
   
2. An excursion in altitude which differs by more than ±250 feet from the altitude reference.
   
3. The altitude changes due to stick or trim inputs by a cumulative total of more than ±250 feet following establishment of an altitude reference.
   
4. The altitude rate exceeds 2,000 feet per minute or the airspeed falls below 160 knots.
