KR87 ADF behaviour
-
Hi,
I am having a lot of fun with the Dukes and as far as I can tell the representation of the avionics is pretty much on point. I do have some small observations on the behaviour of the KR87 ADF, which I took from some testing on the real unit from my aircraft. They are small observations, but if you choose to implement them here are my two observations:
The ADF and BFO buttons on the real unit latch in the pressed position if selected. If ADF is pressed the mode will be ADF, if it is not pressed it is ANT. If BFO is pressed, the unit operates in BFO mode. The other buttons are spring loaded, as simulated.
The FLT and ET timers start counting up once the unit is powered up (for the FLT timer this is modelled correclty). If the SET/RST button is pressed, the ET timer will reset to 0 and start counting up again immediatly. This is regardless of whether the ET timer is displayed when the button is pressed. It also resets the ET timer while the STBY frequency or the FLT timer is displayed.
regards,

Wow, great information! Unlike the KX-155's, I've never had a KR87 in my aircraft, so I'm not surprised these escaped me. To tell the truth, unlike my other avionics, I only implemented my own KR87 to get the correct 7-segment font, and did not go though the process of synthesizing the manual, like I've done for other avionics. That's the real reason for the oversight. I was just trying to duplicate the behavior of the unit in default aircraft, but I should have expected that would not be accurate. Thanks for letting me know!
