Is this chart units in meters or feet? Does the ’ next to the number mean it uses meters or feet?
They all use feet.
Airport charts are typically in feet
what does it mean when the number has an m next to it?
Those are minimums based on the aircraft you’re flying (in this case Class Charlie or Delta).
What is that app?
Altitudes normally I feet and distances in Nautical Miles (NM).
Some altitudes on this chart seem to be in meters (those marked with a m).
Nonetheless some countries use meters for the altitudes (e.g. China). I am not sure how the units are written on their charts.
Looks like it’s telling you the minimum visibility in meters. China and a couple others use metric system in aviation.
Thats a approach of some sorts Im not very good at reading maps but that’s a nice program you got there. Have a link to that site?
