Frequencies reset while switching profile

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   This is a very annoying feature… Having some time to spend at FL100, I deciding to create a new profile, and did not notice that frequencies were reset to 118.00.
What the hell could justify such a function? 

The safe approach would be to keep the active and standby frequencies unchanged, as I do not see the interest to switch back to 118.00.

	I believe the Com frequencies only do this if the VHF kHz spacing is changed from 25 kHz to 8.33 kHz or vice versa.

	You are right! I just did the check with IFD trainer, and I could replicate the bug. What is the point to have the possibility for the same IFD, flying in the same airspace, to have the possibility to have a user selecting 8.33 and another one 25 KHz???

	Flipping the profile from 0833 to 250 does potentially have a valid freq reset, but not the reverse! Having the frequencies switch to 118.00 on a profile change, is much safer than having a frequency change from 125.383 to, what?, 125.375? You may not even notice that change. It is normal commercial routine to force all frequencies, on all radios, to their lowest set on shutdown, to reduce the chances of not setting the com & nav to the correct frequency. There might be some validity to forcing that on the IFD as well, at least as an option, easy to reset your usual frequencies from the presets or recent freq dialog. The other solution might have been to prevent a frequency spacing change when in the air, but then the profile definitions UI might need some work. It seems the best of the imperfect choices here, is what the IFD does, forces a low freq set when the freq spacing changes. * Orest Edited by oskrypuch - 27 Feb 2022 at 3:40pm
