Do you have a ground elevation map for the location? Quoting from <code>resources/elev/Notice</code>: "''When no elevation map is found for an airport, the field elevation value is used everywhere on the ground. This should be OK for a rough approximation on flat terrain, but ground traffic will not follow any slopes, thus may appear as floating above the ground, or digging into it.''" | |||
Read the full | Read the full notice for instructions on how to build your elevation map. Once you have one or decide that your field is flat enough, the next focus is on the FlightGear aircraft models. Each model has its own coordinate system chosen at developer's discretion. ATC-pie must be given the height difference between each model's origin and the aircraft touch-down point (gear wheels) to position aircraft more accurately. You can do this on a per-model basis with ":height" specifications in <code>resources/acft/icao2fgfs</code>. Read the associated <code>Notice</code> file for more information. | ||
A last possible altitude adjustment is available from the location options: "Altitude adjustment for FlightGear views". It applies the given offset to all traffic rendered by the views. | |||

You do not. You can however set the transition altitude in the location settings. | You do not. You can however set the transition altitude in the location settings if your airport specification file does not already include one. | ||
The transition level displayed in the weather analysis is the lowest flight level that is still above the transition altitude. This does not mean the lowest to be expected in ATC clearances, which may be higher, e.g. for more vertical separation on either side of the transition layer or due to coordination with neighbouring zones and fields. | The transition level displayed in the weather analysis is the lowest flight level that is still above the transition altitude.
