Auto pilot dont work
hey the autopilot dont work it is only me ? when i turn it on for follow the planed rout its just turn around in a cirkel if i use the radio fx 112,50 the same happens only follow HDG is ok.
Have you turned knob to NAV ?
Have you clicked on the GPS and set it to GPS and not VLOC ?
It is also advisable to manually trim the aircraft and be on course, before activating the autopilot.
....and don't forget.... AKAIK, it only maintains altitude using pitch, so be prepared to adjust throttle manually when turning using the AP, as it may become unstable otherwise.
Simply activating the AP, with no mode selected -- for example during climb out -- should maintain current bank and pitch... but if I'm wrong I'm sure someone will correct me.
@gabe777 yes i have set it to GPS i do what i all ways have don but the aircraft start to turn left or right and if i set it to follow the HDG its dive
Hmmm... a while since I flew it.
I remember it being a bit temperamental though.
I'll give it another look over the weekend and maybe if there are issues support may help out.
@gabe777 ok thx a lot i have the new Hawk T1/A trainer i can use this in the weekend and i love it
Haha ... me too ... so it will be a busy weekend.
I will fly the Arrow from my home base at EGCK ... Caernarfon.. to RAF Valley, and test the AP... then I can jump into a Hawk and try the Mach Loop.
After much testing I can confirm the AP is very dangerous.
Sometimes bank control works, other times it goes haywire.
Switching from bank mode to heading mode again, causes massive instability.
Given JF insist on tickets one is on its way !
@gabe777 Do you fly the stock planes at all? I wonder if this is an MSFS problem, I've had the AP on both the stock planes and add-ons try to kill me numerous times.
@walterbeech Glad I'm not flying with you then ...
It appears that it has to be used very carefully.
It is important that the AP Heading mode is only activated once the heading bug is centred to current heading.
THEN activate Heading mode.... THEN adjust heading bug slowly...... to desired heading.
If you set the heading bug first .... say to turn right 120 degrees... and then activate Heading Mode.... the aircraft sometimes turns the wrong way.... and violently loses control and it drops out of the sky.
It prolly says this in the manual somewhere
Also switching between modes like bank and heading, can be dodgy, unless the aircraft is trimmed, stabilised and then AP 'disconnected' and then reactivated first.
So Tldr; fly trimmed and stable, activate AP, then select a mode. Ensure heading bug is centred, BEFORE activating Heading Mode.
Altitude hold seems fine. Also activating AP on climb once trimmed for steady climb rate, seems to keep wings level.
So, all good, once you know the rules !
fly trimmed and stable, activate AP, then select a mode. Ensure heading bug is centred, BEFORE activating Heading Mode
Gabe, this is the normal and correct procedure for any autopilot on any airplane. And it is the only proper procedure. You engage the AP from a stabilised flight regime and into a stabilised regime, only then you apply changes. Some autopilots can cope with incorrect activations, but then nothing is guaranteed. So if you've started to follow this procedure only now, it's no surprise you had experienced trouble. And then it is nothing wrong with the autopilot.
Regarding flying with me don't be scared. What I meant to say was that simmers are used to perfectly working aircraft and they expect them to be such. In the real world it is not always the case. It is sometimes a shock for a simmer that something doesn't work in an airplane and everyone is okay about it. AP is not mandatory equipment and it can be malfunctioning and nobody would ground the airplane because of that, because it's easier and cheaper to wait till the next periodic check. I once flew a DA-20 for about 40 hrs before it got its vacuum pump replaced. It was working fine in flight, but on the ground with the engine idling it couldn't provide enough pressure and the gyros would tumble. Everyone was aware. Nobody was creating support tickets or writing on forums about that , because the a/c was VFR only anyway. I'm not saying you shouldn't, I just suggest to take it easier. In my JF Warrior autopilot does weird things sometimes, I just disengage it and don't bother. It only adds some reality flavour to it.
Well it makes sense. I'm used to A2A GAs which -- possibly incorrectly -- let you do what you want.
The Arrow is the first and only addon which goes haywire if you don't do things in a very precise order.
Others have noticed it too, as they too are prolly used to 'over simplified' or forgiving APs.... but clearly if it is actually more realistic, then I'm good with it.
As I said above, I now have it tamed and have been flying around NYC for few hours without incident... well until I realised jyst how high the Empire State building is
...I then disengaged altitude hold, trimmed up to 1500 ft, and re-engaged, levelling out at a 'safe' altitude to enjoy the sights at sunset.
Now I'm getting into the Hawk and will buzz the hills of Snowdonia... and probably wonder why it even HAS an autopilot .
@gabe777 Personally, I'm more inclined to trust that A2A above anybody else would make sure they got the AP on their GA aircraft correct.
I've also found in the Arrow that if you don't do things in a precise order with the AP (switching it on AND switching it off) it throws a wobbly and you're screwed for using the AP for the rest of the flight. I guess this accounts for the numerous posts about AP problems. I've got used to that precise order but it would be nice to have it working correctly without the glitches.
Well I posted a ticket to JF and Mark said they'll be looking at it.
So if it is a bit twitchy and inconsistent hopefully it nay be improved.
But for now it's usable if, as you said, you treat it really carefully.
