NAV1 and/or NAV2 tune 0.00

Recommended Posts

FSX SP2 

WIN7 64Bit

CRJ Installed version: 1.2.2.0
AIRAC: Navigraph 1809

 

I have noticed that my NAV1/ and or NAV2  radios autotune to 0.00 and even if I select 'MAN in FMS, I'm unable to re-tune either by using the FMS keypad or the   RTUs. The frequency is reflected also in the backup tuning unit. 

 

I need to do some a test flight to figure out whet this happens I have noticed this with some add-on airports even without ILS. 

 

Does it make sense to enable LOG in CRJ manager and to what level ? 

 

Regards

To be quite honest: I don't have the slightest idea why this could happen. Do you have any hardware connected that controls the Avionics Master switch?

 

Logging won't help here. None of the radio tuning stuff is being logged.

No tuning hardware. 

I will try to investigate further and I will come back

Removed LGHI freeware scenery and flown LGMT LSV H59 MES LGHI

I got again 0.00. I gat also scratchpad message 'LOC WILL BE TUNED' 

I selected VOR01 arival via MES vor. No ILS on both dep or dest airports.

I will remove LGMT add-on tonight and try again.

no freeware airport bat 0.00 on active frequency is here..

I manually tuned LSV vor on NAV1 just after departure. 

Though NAV1 shows 0.00 LSV VOR is still tuned when selecting VOR/LOC1 source. 

I will try a route between airports in Germany or France next time.

 At 1500 AGL GEAR DOWN FLAPS 20 selected VOR/LOC1 and I was able to tune HOS VOR 110.80

I don;t understand what is happening...

Default FSX Scenery.

EDDF rwy18 -EDDM ILS08L

EDDF RID AMTIX AKONI Z74 T104 ANORA ANORA3A EDDM - (via MIQ MAGAT - ILS 08L IMNE 109.50)

 

Here is the catch: ILS 08L IMNE 109.50 nowdawy but FSX default scenery with 'ancient' navaids: ILS 08L IMNE 110.30

I never got  ILS tuned. Having NAV in MANual trying to tune 110.30 it was reverted back to 109.50 either via FMS or RTU

There has no 0.00 in FMS or RTU but I got red LOC1 in red box and red 0.0NM.

Looks like it autotunes to FMS database frequency once arrival RWY is selected.

 

See here, in my dropbox a relevant video and screenshots of my findings. I hope it helps.

That's the problem if scenery doesn't match navdata. The only choice you have is to either get a scenery that implements the 109.50 or change the navdata to the frequency of the FS scenery (110.30). The CRJ itself doesn't have much to do with all this. The next update will allow to change the frequency after NAV-to-NAV transfer has happened though. That will help to work around the actual problem.

Good to be able to change frequency, as if Flight simulation platform in use does not allow navaid update the simulated aircraft need to adapt for platform short-comings.

Thanks for having problem solved.

Experimental 1.2.2.3 Solved the Issue 

Thanks

 

I'm 100% sure it doesn't.... Nothing was changed in the radio system.

I believe, the following solved my problem:

v 1.2.2.2/ Rev 358

 [Fixed] NAV-to-NAV transfer doesn't block manual frequency tuning any longer

Checked with EDDM ILS 08L 110.30 (FSX default scenery) I was able to tune and follow ILS

Many Thanks !
