Nah.. with the autopilot-mod the AP intercepts and holds the radials of a VOR like a charm. But there are no amber (armed) conditions.
Say I fly with HDG and ALT HOLD and like to intercept a radial of a VOR station tuned on NAV1. So I select VOR/LOC on both FD and AP, and the AP indicators immediately turn green (they should only do when capturing the radial!). Also the HDG mode is not cancelled when getting in capturing range, this has to be done manually (same with glideslope intercept when on ALT HOLD).
