AutoPilot STRG SEL. Pilot Error ?

[Droning_On]

Hi guys,  this is probably just me but i cant seem to get STRG SEL A/P to work on a Cold startup. 

 

INS is all aligned (wait the 9min till its flashing RDY) changed to NAV mode then after takeof STRG A/P mode doesn't work ?  Im just using the cold quickstart options to practice my startups so all steerpoints are in by default.

 

seems to work fine on warm starts or Air Starts...Auto sequencing too!!

 

What am I doing wrong during startup?  Thanks in advance. 

 

Edit: Just noted the Distance to steerpoint on the EHSI has a red score through it ??

As you seem to be able to use it when starting in the air I won't assume you're doing anything wrong when enabling auto pilot. Most obvious thing is, are you aligning your INS correctly? If you're doing a normal alignment with the INS knob to NORM you need to at least confirm your coordinates and system altitude by pressing enter on lat, lon and SALT. If you've done this correctly and wait for the INS to align you should face no problems with the autopilot. Second this is, do you have the steerpoint. In dcs your steerpoints are missing until you've entered in the coordinates, meaning that it is essential to have selected a steerpoint with coordinates assigned to it. If you've done all these things correctly and it still doesn't work then you will just have to assume that it's a bug. Make a track file of a flight where you're showing the bug, and then post it in the bugs section. Have a safe flight!

Is heading and attitude mode working for you?

When doing alignment:

Set INS knob to ALIGN

Type in current position L/L in DED: e.g. N12 34.567' ENT E123 45.678 ENT.

Type in new system altitude (option). 123 ENT.

When at status number 10 or before takeoff set INS knot to NAV

 

You can't just ignore the L/L numbers on alignment nor can you just press enter for whatever numbers are already there.

On a related note I have found that after entering a new steerpoint on the DED the auto pilot will not recognise it until I select another steerpoint momentarily then switch back to the new one.

Also if you use the Stored position alignment it’s all done within 2 minutes. Not sure if you still need to enter the co-ords after?

True, IRL you need to re-entre the coordinates or else the alignment will be flagged as degraded, but in dcs the INS isn't modelled correctly at all so that is why I said " you need to at least confirm your coordinates"

you dont. Stored heading is the best way to fly the -16

Sounds like im not confirming coords or alt........  . I’ll try tonight  thx

Yep. Works fine

Thx frederf.

If you are going for the full align you may as well wait for the status to reach 6.

according to the manual you can go to Nav at 40 but the system will potentially have 4x the error rate that 10 would have, 20 would be 2 x the error. 10 is the best a stored heading align will give you but you’ll get to 6 on a full align (0.6 x the error of 10)

im not sure if this is even modelled but FYI

[Florence201]

Regardless of which alignment you’re doing, you MUST wait for flashing ALIGN in the HUD. That is when the INS has the information it needs. STORED, do not Enter the LL on ICP initially. Norm, then Enter displayed LL by Enter, dobber down, Enter

I've had this problem as well, and it's been caused by going with a partially complete INS alignment. You need to wait for RDY to flash, if RDY is steady it's usable but some things like autopilot steering won't work. 

 

The simple way: set INS to STOR HDG, no need to interact with the DED at all. Wait for /10 and flashing RDY, then set INS to NAV. 

 

If you want to do a full alignment, set INS to ALIGN NORM, then check both LAT and LNG on the DED (if you're doing a cold start and haven't moved they'll be correct) and confirm each with ENTR on the ICP. You have about 2 minutes to confirm the coordinates before it screws up the alignment. Now you can wait for a flashing RDY at either /10 which will be a normal alignment or /6 which will be an enhanced precision alignment. Once you're there, set INS to NAV.
