Help! How to effectively use Su-25T autopilot

[uboats]

These days, I started to learn Su-25T autopilot.

 

However, I was totally confused about the autopilot disengage and trim reset.

After disengaged the autopilot (alt+9), I used (Lctrl+T) to reset the trim. However, it did not work at all. So every time disengaging the autopilot, I had to manually reset the trim by Rctrl+,;./ which made the flight poor efficient.

So what's the connection between autopilot and trim here if trim reset does not work after autopilot disengaged? (For su27, disengage autopilot, the trim reset does reset the trim)

 

 

Another problem is that do I need to frequently engage the autopilot once the flight condition has been changed (roll, alt, level...) like what we always do in Ka50? Since the flight condition is quite sensitive to the weight load (unbalanced)

The Su-25T doesn't have a reset trim function; you need to reset it manually. The alternative is to use a level flight autopilot mode (i.e. barometric altimeter) and turn off the autopilot once you are established. This has the effect of automatically trimming your aircraft for that airspeed.

As stated above the Su-25t does not have a functional trim reset button. Other than using the autopilot trick mentioned to get level flight trim you can just adjust your trim until the trim lights indicate neutral position.

As others said, trim reset options are either manual, or using the level flight mode.

 

Do you NEED to re-trim frequently? Not if you keep a hand on the stick most of the time. On the other hand if you want to keep the stick at a neutral position you'll need to trim, and I suspect that most 25T pilots trim with the autopilot rather than doing it manually. It usually takes 5 to 10 seconds to get really well balanced if you're not maneuvering too much to begin with.

 

Learn all the auto-pilot modes well if you have the time. They can be very useful in setting up ground attack and bombing runs once you've mastered them.
