Experience with L-39 and new RSBN/PRMG objects

[gulredrel]

Hello,

first of all. Many thanks to ED for implementing the RSBN and PRMG objects. 

What is your experience with the new RSBN and PRMG units for the L-39?

Tried it on Syria placing RSBN and PRMG units for RW17 at Latakia. Works great.

One thing I need to investigate further with a clean mission in Caucasus I guess. Having the L-39 in landing / PRMG mode (forward position of RSBN switch), the needle on the HSI swung around while passing the PRMG glideslope object.

Being in navigation mode (middle position of RSBN switch), the needle swings correctly next to the RSBN car further down the runway.

 

Thanks

Jens

I now did some testing in Caucasus. At least both the map's own and manually placed RSBN/PRMG stations behave the same.

It's still not clear to me to where the HSI thin needle with the circle at the end is supposed to point when in landing mode.

Please find tracks attached. Also the following what I've found.

Being in navigation mode, the needle points to and swings around when passing RSBN station.

Here in Kobuleti with manually placed RSBN (RSBN car placed at around the 45° left position):

 

Same behaviour in Maykop with map RSBN (RSBN to right in the revetment): 

 

Now comes the weird part. Setup is the same RSBN channel tuned to RSBN and PRMG to PRMG channels.

Being in landing mode, the needle points and deflects to the left, when passing the PRMG glideslope car having it on the right front side (next the ILS(?) antenna):

Same in Maykop, needle swings left:

 

Where should the needle be pointing to when in landing mode!? Why it is swinging to the left when approaching and passing the glideslope car having it front right?

If it's a bug, feel free to move the thread to the bug section.

Thanks

Jens
