munich jepp chart and atis question
Hi all,
I just operated to Munich. Have 2 questions to ask.
1. On the munich RNAV SID jepp chart, eg 10-3V7. the heading says RNAV SID(OVERLAY). What does the word OVERLAY mean? I thought we have to overlay 10-3Q5 to get all the necessary information but does not seem like the case. All the required information is already on 10-3V7
2. During departure, it was snowing. The ATIS reported medium braking action 26R 62 64 26L 53 54
What do the number 63 64 and 53 54 mean?
Me and my crew thought that it was the braking coefficient but we looked up the ICAO definition and those number represented good braking action.
And it certainly was not depth of deposits because it was only lightly snowing and the runway was only slightly contaminated and damp with de-icing fluids.
Any help would be much appreciated
