Can Collins Proline II controls such as the CTL-62 be used with Proline I units such as the ADF-60A?
Yes, with the use of the CAD-31 and CAD-62 Control Adapters. The CAD-31 allows Proline II controls such as CTL-22 and CTL-32 to be used with the VHF-20A /VHF-20B and VIR-30A avionics units respectively. The CAD-62 allows Proline II controls such as CTL-62 and CTL-92 to be used with the ADF-60A and TDR-90 avionics units respectively.
