it is different. examples:

a6m's = 146
109e4 = 150
109f4 = 155
109g2 = 160
c205 = 164
f4f = 150
190a5 = 159
190d9 = 169
i-16 = 129
hurricanes = 140
ki84 = 163
mossies = 170
p51's = 174
temp/typh = 185
spit 5 = 160
spit 14 = 175
p40's = 144
p39's = 162


why do i have these #'s handy? i was bored one day and tested every plane :)   :huh  :uhoh

are thous Vy or Vx speed? (I'm pretty sure it should be Vy but I don't know for a fact)

I am actually asking for the ability to be able to set my climb rate for autopilot (like a dot command). I understand as you increase in altitude you will stall out.

If I'm in a cruse and I want to enter a slow climb I'd be able to just type climb .1000 and start a 1000ft/min accent.

You can do this simply by setting the correct speed with the .speed xxx command and using auto-speed. You just need to take a minute to find the correct speed and note it for future reference.

I have no idea, they are the speeds HTC has coded in by default. I would guess they are a compromise between Vy at all the various weights the plane could fly at, but I'm no expert and dont have the real life documentation.

It will depend on your power setting, speed, altitude, and airplane. Would be a lot easier to just have to dot command for the climb rate.

It has nothing to do with real life documentation, just need to find out what HTC programmed.

I know what he is asking for, it's used in modern autopilots (i'm thinkin airliners), VS hold (or maybe VS select?) if i remember correctly is the name of the ap mode. I think it would be of limited usefulness in the game, since we're mostly dealing with oldschool prop planes where the performance is so different thru different alts, and we aren't dealing with air traffic control who like to see predictable vertical speeds in order to separate IFR aircraft from each other.

however, .speed (alt x) wont work to maintain a VS.  .speed commands pitch to maintain a speed.   likewise the auto-angle (ctrl x) just commands pitch to maintain the pitch attitude, wont maintain a VS or a speed -- the VS and speed will go wherever they go.

the OP's wish is to have the autopilot command pitch to maintain a vertical speed, and let the speed go wherever it goes.

exactly, thanks

P.S. The name depends on the autopilot

machfly, that's not how you started this discussion...your op makes it appear as if you want to be able to use an autopilot function for max climb rate + max climb speed in a fight...
Say you have 3+ enemy fighters on your 6 and they are all faster than you, but you are capable of outclimbing them. So you just set you autopilot to climb at 5000ft/min (or what ever your airplane can do) and you'll be safe (just make sure you don't stall).

still say you're being lazy...we can do what you're wanting to do with a keyboard + stick combination...

Yeah I started the discussion during the end of my 3 day of no sleep period, used a bad example. Sorry about that.

Sure I can do it with a stick, but what's the point of having an autopilot at all if you can do everything with a stick?

If you want easy just hit auto speed.  :D

Don't get me wrong, you can wish for whatever you like.  :aok

Why do you want this?

HiTech

Say your cruising and want to make a shallow accent or decent. You can just set it to 500ft/m or 1000ft/m (of what ever) and there you have it. Here is a more specific example: Your flying at your mil. power to a fight 50 miles away. A squady tells you that there is a con at 12K, your flying at 10K. You want to be at least as high as that con not to be at a disadvantage but you also want to get there as soon as possible. Therefore you don't want to set your speed to the best climb rate because you will loose a lot of that speed and it will take time for you to accelerate again. You know that a given speed it will take you 4 minutes to fly that distance. So you set your autopilot to climb at 500ft/m and you arrive there at the fastest time and at the right altitude. You do not really want to be keeping your airplane on manual control for thous 4 minutes.  

Also if your coming back to the airport and you know that at this distance, at approximatively this speed (your speed will change but not by much), and this decent rate you will be at the right altitude by the airport so you start your decent at that rate. (I know you know this one because your a pilot as well).



EDIT: Ignore my first explanation on the first post. It was after 3 days of no sleep and I was being retarded. It's a lot better to keep your airplane on manual control in that situation.
