How to use both ARCDUs?
Hello, for a classical navigation from VOR to VOR I wanted to enter the frequency of the first VOR to the left ARCDU, using NAV 1 and intended then to switch quickly to the right ARCDU with the Frequency of the second VOR using NAV 2. My problem is now that entering a frequency to the left ARCDU, this appears also in the right ARCDU Of course I dont have the selector on "Both". How can I enter and use Frequencies independently?
