Multiple Frequencies
Whilst transiting a zone at the weekend I overhead the following conversation on the radar frequency I was using - there were 2 published:
G-XXXX: XXXX Approach request zone transit.
APPROACH: G-XX Call on 123.45,
G- XXXX: XXXX Approach G-XX, 123.45
APPROACH: G-XX transit approved, etc.
We didn't change freq but heard G-XX on both calls and the same controller answered him on both calls, but presumably G-XX changed to the other frequency as requested.
So...
When its quiet is there any point operating 2 approach frequencies - especially if the same controller is working both?
Why if we could hear both transmissions did G-XX need to change freq? Was it a case of same guy using 2 transceivers? Is so why could we hear him both times?
Similarly - why have an approach frequency and a tower frequency at small field when again the same controller is operating both.
Seems to me to be an unnecessary increase in pilot workload - especially in view of the numerous potential infringements in the area.
