Hi there,
Odd - but obvious to many I'm sure:)
Why are my nav radios tuning themselves automatically? In the
good old days of no PM and just PMDG I had to do everything
myself, but now my nav radios tune magically to my next
waypoint.
Can someone point me in the right direction here (no pun
intended)? When I get myself a hardware radio panel I'd like
to twiddle the knobs myself!
Thanks,
Paul
You can turn the auto tune off.. and then you can toggle the "Auto Tune
Navs"

I knew it would be simple, but didn't know where to look!
Many thanks,
Paul

Hi Paul,
Go to the menu of your CDU and push twice then select SETTINGS and change
AUTO TUNE NAVS in OFF. That's all
Have nice flights

The thing is:
most modern planes do have autotuning!
All the pilot is required to do is to check if autotune did it's job
correctly or not.
I agree that twiddling the knobs is a nice tactile addition to authenticity,
but technology moves on...

Hi from sunny Athens,
before 3 weeks i had the opportunity to be in a real 737-400, parked in the
Apron of LGAV, for about 3-4 hours. We made a video for the 4th Greek
Flightsimmers meeting and i tryed to get any information i could in this
time.
About Autotune function, the true is that is something like customer's
choice.
Olympic's aircrafts they have a 3rd NAV radio, not operational from crew,
for
autotune nav, needed for IRS check position.
Some other aircrafts, Olympic has from rental, they don't have the 3rd NAV,
so
they have the Auto/Manual option and the crew decides how to use it. So if
there is not NAV tuned, the a/c has only IRS position and not confirmed
with
NAVs.

Hi Paul,
why donīt you switch auto tune off on the CDU?
You can find it here: Index -> settings. Here itīs the LSK2 if I remember
correctly.

Thanks everybody!
I saw that the 747's CDU tunes the radios, but I didn't know
the 737NG could do the same.
Does this mean that when I add hardware radios (I have a
CPFlight MCP, so I might go for their radios as well) they'll
be able to tune themselves from the PM CDU software? I like
the idea of having a choice - leaving me to tune the comms
radio and drink coffee.

Hi Paul,
canīt tell for sure whether their radios have a push button for manual / auto
tune, since I built my own with FSBus.
But in principle it should work as the system is the same:
reading and writing to FS Offsets.
Itīs alot of fun having the choise.
BTW the autotune is on CDU -> Menu -> maintenance -> settings -> LSK2

Hi Paul,
Just for clarification.
On a real life B744, the only way to tune your nav radio's , is via the
NAVRAD page of the cdu's.
Voice radio's are tuned by one of the 3 voice radio units.
The tuning of radiobeacons is a very complicated progress.
The FMC is using a autotuning of random beacons for position calculations.
These has nothing to do with an enventually autotuning of beacons necessary
for the routing in the flightplan. Same for approach or take-off
procedures.
You also have autotuning of the ILS freq for exemple when certain parameters
are met.
Finally the crew can manually select every VOR of ADF / ILS they need or
find necessary.
So, you see, much more complex than just an autotuning of the beacons in
your flightplan.
If this is the case in a B738, I don't know, as here the technic is must
older and more related the older B737 for compatibility reasons. It's
certainly working the same way in B767 or B777.

Thanks Michel,
I'm not familiar with the 747, but will now have to get my
737FMC handbook out and clarify the situation here!
From memory, there's no radio page in the 737 FMC, and all
tuning has to be done through the NAV radio panels, but there
may be some options in there that I haven't seen.
