What's my fault?
I can't find a switch to activate the radio panel.

If I start all engines no radios available, I can't change the frequences of NAV or COMs.

Only if I use Ctr E they are working?
Maybe I'm blind?

Battery switch not on; top left engineers panel, black toggle cover.

Battery Switch is on. Thats not the reason.

If I connect Ground Power, the switch for this at engineer panel also can not be used. In old version I could use ground power, but now the switch can not be used.
(Parking Brake, Chocks, no difference)

And the right forward door looks open from outside few from some angles. It's closed, but disappear sometimes.

Everything else works fine. I use 2 CIVA and it would be good to get on NAV2 a sequence before starting the engines.

Don't use the 2d radio panel. It appears to freeze the ground power switch on the engineers panel. Use 3d on the console. See if that helps.

Shut down FSX and restart it and the problem goes away, as long as you don't use the 2d radio. You can shift2 BA EP and go to backup power plus have radios.

Edit:
Last night I was switching between the 737 and 727. That must of screwed something up with the gauges. Today I loaded only the 727 and the radios work regardless of ac power, ground power, or battery on or off. 3d only, never use 2d.

Ok, will try this. Battery switch I used at 3D panel, then opened the 2D panel because I use the TCAS inside this for flying online. Will try to use only the 3D panels until engines are running and report. :)

Did you get it to work?

No.
1. Start FSX
2. Load B721-200
3. Battery On, Galley Power On ... (3D Panel)
4. No com or nav available at 3D-Panel

Can only change them if use Ctr E before.

It would appear your Avionics Master is off. There's no switch for it so you'll need to create a keyboard short-cut.

Select the menu 'Options', 'Settings' then 'Controls'. Choose the 'Button/Keys' tab.

Scroll down the 'Assignment list' and select 'Avionics master (on/off)'. Now select the 'New Assignment' or 'Change Assignment' button.

In the dialog box, select the keyboard combination to use, i.e. Ctrl + Shift + A, then select the 'OK' button.

OK, maybe I need to download again.

Shift2: click EP external power and BA bleed air (bleed air switches open and packs should be off for start)

This switch can not be moved:
3. FE console: External power switch: on
The light shows External Power all time, independent from Shift 2 and EP/ BA On or off.

But dual CIVA, TCAS, everything works fine.  :)

@Paul, thanks, I really use dark and cold for all airplanes. Maybe thats the difference. I will try this.

Thanks fsxPaul, I use a shortcut for the avionics master switch and now everything works fine.  :)
