Issue with waypoints after full INS alignment

[VTJS17_Fire]

Hi,

 

I don't know if it's a bug or if we did a big mistake with the ILS alignment and waypoint selection.

 

Four of us did the full alignment, as described:

+ battery: on

+ ground power: on

+ PCN operational mode selector: STS

+ INS/ PCN mode selector: ALN

+ VAL button: push(ed)

... waiting 8 minutes for the class 1 aligment, until pret glows (not flashing)

+ set DEST: insert 01

 

My comrades did the same and we all got the same LAT/ LONG coordinates, with the parameter selector set to L/G.

 

1. But we all got different ranges on the HSI to our waypoint 1 (which is also set to bullseye), from 20,9 NM, to 32NM and 41NM. The bearing is same for all of us. The waypoint 01 is the same for all of us in the missioneditor.

 

2. If I switch to CP/PD I should get the heading and range in the INS display, but only got "-- - ---".

 

 

I attached the screens from three of us, the mission and my trackfile. Maybe you can help us or confirm this bug.

PS: After a few tests, my comrade got other ranges everytime he choosed a slot or restarted the mission.

Have you corrected the WP00(aircraft position) coordinates?

Make sure your waypoint(WP01) is selected by PREP.

Did you select the PCN mode to Normal (N)?

 

Have you put the INS/PCN to Nav mode?

1. See Cantiga's answer, you forgot a mandatory step.

 

2. No you should not. CP/PD is not to display heading/range. See Razbam's manual ;)

Have you corrected the WP00(aircraft position) coordinates?

No, thanks. Is this a real step or just an WIP issue which will be solved in the future?

 

Make sure your waypoint(WP01) is selected by PREP.

Yep, it was.

 

Did you select the PCN mode to Normal (N)?

Yes.

 

Have you put the INS/PCN to Nav mode?

Yes. Forgot to mention these two steps above.

 

2. No you should not. CP/PD is not to display heading/range. See Razbam's manual ;)

Thank you. I thought, I saw that in the previous versions.

AFAIK it is.

 

According to the manual you need to check wether WP00 has the correct coordinates prior to the alignment:

 

3. Check that the Aircraft position in Latitude, Longitude and Altitude indicated by the

PCN are correct. Change them as needed (see Data Entry for more information).

 

INS Alignment is covered from page 90 onwards
