The white squares are aircraft - it's course is indicated by a line. Then there is a datablock showing Callsign "FWA170C", its altitude F053 = Flighlevel 53 = 5300ft, climbing to an assigned flightlevel 190 = 19000ft. A = altitude - below a defined transition level F = flightlevel (steps of 100ft) - above a defined transition altitude

Transition altitude and level depend on the location and weather.

Then you have the airports, navaids, nav-fixes and the control zones showing.

  • $\begingroup$ I believe the C in FWA170 C (there is a space, I believe) might be transponder mode being Mode-C. $\endgroup$ Oct 1, 2019 at 14:07
  • $\begingroup$ @tsg thanks and how could the ATC know the aircraft is climbing to FL190? Is that reported by the aircraft? $\endgroup$

    $\begingroup$ @SentryRaven C is an indication of the current sector ("Center"). $\endgroup$ Oct 1, 2019 at 17:00

    $\begingroup$ @Jan, yes, and the short line coming out of the centre of the square is the current movement vector. I think its length is 5 min of flight, but I don't remember exactly now. $\endgroup$
