Airbus drivers query

[Check Airman]

Having used the 0-9 keypad on another airplane, I prefer the tuning knobs. Airbus may have a better design interface though.

I did not express myself clearly. Let’s say the active frequency is 123.8 on VHF1 and CM1 has communication. If CM2 takes communication and changes frequency on RMP2 instead of RMP1, then 123.8 is lost.

123.8 would then be in the 2nd window of RMP2.

So it would appear that the non-use of SEL mode is due to fear of losing the last frequency which comes from a lack of understanding of how the RMPs work? Is that the only reason?

My bad Goldenrivett. I take it back. You are 100% right. I got confused as I never use the SEL mode for VHF1 and was trying to picture the scenario in my head. xD

Well not only. There is less chance of messing up and confusion if you dedicate only one RMP to one VHF. But I'm sure with proper training and understanding, the use of the SEL mode is a great tool. I'm just not using it for VHF1 as we are not supposed to by our SOP.

In a previous company we were supposed to always switch back to the onsite VHF after using SEL mode on RMP 2 to set VHF 1. That did indeed create more confusion than not. Now i work in a company where the SOP is to have both RMPs on VHF 1 at all times and it is far less confusion. One just has to remember to switch back immediately after using VHF 2 or 3.

Keep the lights in a line. Can't mess up!

The first part of the sentence is correct, making it more of VHF1 would be more accurate. RMP is basically a tuner and it's very purpose is to prevent hands crossing all over. I have not seen any other Asian carrier do it
