Speed Specific Combat Trim

[100Coogn]

To me, it sounds like a wish for cruise-control.

I dislike the idea of being able to dial up various specific trim settings via the command line, doesnt seem very realistic to me.

I can't seem to find the combat trim button in the few photos I reviewed of WWII aircraft cockpits.  If we follow the realism logic, there is a lot that would need to be removed from this sim.

I understand your desire, but I can see multiple ways to implement it.

1. Save trim mode, this is just push a button and it locks trim into the current settings from the auto pilot.
    Then when you go out of auto pilot, trim will always return to these settings like the return to combat trim position now.

2. Similar to above , but is set from the .trim command like your request.

3.  Set with either of the 2 methods, but instead of always going to these settings when turning auto pilot off, it only goes to that position when a button is pressed.


I don't think I would implement 3 , because I believe it's major use would be a get out of jail free card with planes like the 109 in high speed dives.
I sorta like the idea of having both 1 & 2, I.E. the .trim command just overrides the position set by mode 1. Also I don't think they would move instantly , but take a few seconds to move from auto pilot to preset position.

I like option #1 as I can just program the toggle into my Pro Throttle as opposed to having to type it the dot command like in option #2.

I like both the idea of a Save Trim and a dot command together

I don't mind that it may take time to set the trim as the 109 had a wheel with a chain attached to set the trim, and that took about as much time as it does now to set.

Are you talking about the "trim set" command we already have?  It's key-mapped, & can be seen here: options > controls > keyboard commands > flight

Trim Set - KEY_DOT

I don't seem to be able to find any description for this one. Does it force an instant CT trim setting when you are in manual trim mode? Like when you move the stick to level out of auto climb and your pitch and ailerons are set too extream for level flight?

What it does is trim your plane to maintain your current orientation. For instance, if you steady up into a climbing turn and hit the period key, your trim will be adjusted to maintain the climbing turn with your stick centered.

What everyone here is wanting is a way to preset the trim to maintain level flight with zero stick input at a given speed, even if you're not currently flying at that speed.

Ok thats why I got better results tapping CT occasionaly. The best set with Trim Set was around 300 and it averaged for above and below in combat. As I tested dives above 350 hitting it got truely bizare results. CT dialed in the trim for the speed then I toggled it off.

What everyone here is wanting is a way to preset the trim to maintain level flight with zero stick input at a given speed, even if you're not currently flying at that speed.

But that's just not possible without automatic throttle management. Lets say when level and at full throttle you aircraft maintains 300kts. Now you trim it to maintain 250kts. It will maintain 250kts, but it will do that by initiating a climb. If you want to maintain 250kts, at the same flight level, you need to back up off the throttle.

I believe whats actually being asked for is an ability to preset a particular speed value and instantly trim to that particular speed. I do something similar to this at the moment. I use the speed mode of the AP (Shift X on my setup cant remember the default) with my speed set to 260 kts (what I believe is the ideal cornering speed in my P38) right before I enter the combat area. I back off on power to stay level or more often just allow it to enter the shallow climb just before I engage. Because my CT is off, when I exit autopilot it maintains that 260kts trim throughout the flight. Its not some super duper magic trick, just helps me set a reference.

Ofc, this is possible only with CT off. As soon as u set CT back on, it will readjust the trims to whatever speed range you are in. Cant remember the exact values, but I think CT trims within the nearest 25mph?

Hazard: I had to read it multiple times to understand that what he is saying is.

A way to have the trim set to a preset position say 300mph. Even if you are flying at 200 at the moment.

To expand upon "what we think the OP is asking"  ...

The ability would be to have a trim position programmed and ready to use at the push of a button. So he's climbing out at 200, expects to enter his fight at 350 so pre-programs a trim setting for a speed of 350 (but doesn't actually have the trim set for 350 yet). He uses combat trim or auto-speed autopilot or whatever for the climbout and transit to the combat area.

Now he's on station and looking for a fight, sees a bad guy so throttles up to 350 and engages his preset trim and off he goes to fight. His trim stays where it is the whole time, instead of constantly changing like when using combat trim.

I personally don't see the ROI for this feature, since you can engage combat trim for a couple of seconds and fine-tune it manually, and then it's set until you change it.

Dot you are just complicating and confusing. It's just as simple as what HiTech stated above your post;

HiTech

The little red lines with no markers on them in the Cpits currently are not good enough for trimming efficiently before entering combat.
Not to mention in many cases using the Combat Trim on and off trick does not save it's position but often causes a nose down attitude.
You might not see a use, but I do and it's a faster way having a dot command than having ask HTC to go through all of the current aircraft and asking for the trim to have makers for airspeed on the trim indicator.
And I have not asked for the trim to be applied instantly because that would be overly gamey.

[bustr]

The idea is sound. Can't be anymore gamey than toggling CT but, more exacting on your attention span in the cockpit.

Still think if it's implemented you get at least 3 speeds(zones) to set.

Tmode1 - 120ta
Tmode2 - 250ta
Tmode3 - 350ta

Then you can either toggel CT to account for anything else if it dosen't feel right. Or use manual trim to tweek. Even allow for each aircraft a calibration and set procedure.

3 Buttons to select 3 trim states. Or a Dot command (.trim 1, 2 or 3)

1. - While flying auto level at your speed choice enter(.TrCap 1, 2, or 3). Your trim settings at that speed will be captured.
2. - Will need a dot command(.Trdump 1, 2, 3 or all) to clear calibration choices.
3. - When your trim mode has been set you are free to tweek it with trim buttons or turn off with Auto Level or CT.

This has the makings of some interesting abuse of reality during our sycronised airshow aerobatics and Quake Tourny spin jumping we call furballing and deuling.
