Proline 21 RT Frequency lost or missing
Hi All
My company has had some issues lately with our Proline 21 equipped Kingair. I was wondering if anyone else had experienced anything similar.
On more than one occasion crew have found themselves on the wrong frequency or on a dead frequency, with the assigned frequency nowhere to be found (i.e. not in standby). This is after having checked in on the correct frequency.
As I understand it the RTU is the primary tuning unit although I know some crew prefer to use the CDU and there are gotchas with that. So although, "finger trouble" would seem like an obvious place to look, has anyone experienced any technical bugs in the system that could cause this?
Cheers
