I have not been able to find information on this scenario: If I have an EFIS unit and an EM unit installed, and the EFIS unit goes black, can I revert the ADI display to the EM screen as a backup in IMC?
I suppose this means I should scrap plans for a King KN-53 nav receiver? Is there a list of nav receivers that will work? How about NARCO products? I thought one of the major advantages of the HS-34 was to increase interface flexibility?
