Description (last modified by smoser)

Today (2013-04-01), I have seen several landings that were not recorded correctly. Especially tow-planes that lost connectivity on the runway make troubles. Investigate in that.

There is currently not much we can do about that. The landing is not recorded if transition AIRBORNE -> TAXI,PARKED is not recorded. That can happen e.g. in the following scenario:

  • The plane disappears before the landing is recorded. This can happen when the antenna is not optimal placed (radio deadspot, ...)
  • The plane re-appears, but it is now taxing on the ground.

Once that we introduce the concept of a "Flight" this will become better.

As a workaround: The visible devices are removed after a long time (default 16h). If we loose connection before the landing is recorded, the landing will be recorded as soon as the device re-appears. At least the book-keeping is correct, even if we cannot determine the flight time exactly.

Note: See TracTickets for help on using tickets.
