For whatever reason, at some airports, contacting the tower.. meets with no response from PF3
This is undoubtedly the 'fault' of the aircraft I am flying - one or two of which do not respond properly to the PF3 VCP. The Flight Factor B777 for example: if you enable the 'radio plugin' for that aircraft, then the VCP will autotune the radios for you, but with the plugin active, you cannot manually adjust them. So when I get to a runway and hear nothing (original question) and press my usual shortkey, all I get is a radio check. And I can't retune the radio to the tower frequency myself: that only happens automatically (VCP) if I find the trigger spot.
Well, I guess this is all 'X-Plane stuff', but one way around it would be to move the trigger point to the end of the taxiway, rather than a runoff point at the far end of the runway. But I am not sure what PF3 is looking for within the XP11 files which will initiate the 'contact tower' instruction.
Key 6 cancels the TGS, requests permission to take-off, and instructs you to "position and hold" and clears you for take-off as soon as you are facing the correct direction. The latter is conveniently clever, it allows you to start your take-off from where you are, if you so choose, if you feel you have enough runway to do that.
Thanks. But presumably, if I am still forcibly tuned to Ground, as per the above, rather than Tower, it's not going to be available.
