Guys, note that it IS NOT flyinh HDGs on the SID, STARS... They are TRACKS, yous hould apply correction to wind and everything in order to follow it. LNAV will correct itself but till you seat on a CRJ or B737 make sure what you are flying is a TRACK and not a HDG. For the rest is really slow but real good information. regards!
Yes, it creates a little bit confision. But when doing a breafing or reading the chart the minimums ( of Ceiling) is read in Feets while when talking about Horizontal Visibility is read in Meters, the best example for this it's a METAR, as you can see, the HV is given in meters, and the ceiling or cloud coverage it's given in Feets.
In most cases, the runway number is the course divided by 10 rounded to the nearest whole number (.5 rounds to the nearest even number). If you have two parallel runways at 195deg, they would be 20L and 20R; three parallel runways at 195deg would be 20L, 20C and 20R.
