In the example above, crossing the orange or purple line yields single tone
alarm and brings up CTR Info Page. Crossing red line yields double tone
alarm and brings up CTR Info Page. A pilot at the blue target is inside the
400m horizontal warning distance and therefore would have received the
single tone alarm and CTR info page would be automatically displayed. Note:
since the horizontal distance is the threshold that was broken, the warning
distance is highlighted (figure at right). On the other hand, if the warning
distance in the vertical direction was broken the Low/Up parameter would
have been highlighted. The distance to the nearest Airspace can also be
seen in the user-field Dist CTR. The display is limited to distances of 50 km. If
you enter a airspace, the Dist CTR will display 0.00
In the example above, the airspace type is CTR, the following are the
available airspace designations:
D Danger Areas
AWY Airways
FIZ Flight information zone
CTR Controlled airspace
TMA TMA
R Restricted Areas
TSA Temporary segregated areas
VZ Forbidden zones
FLF Airways
HPO Heliport
GG Danger Areas
HI Obstacles (e.g., cables)
SZ Wildlife protection area
BB Cable car
7.1.1 Recalling Detailed Airspace Information
The CTR info page can be called up anytime with a short press of the i key
and the five closest airspaces are shown. To see the details of one of the
displayed airspaces, highlight the desired airspace with ▲▼ keys and short
press the OK key. The details will be shown as in the example at right.
Typically OpenAir files will only contain the name, perimeter and floor/ceiling
limits of the airspace. However the instrument is capable of displaying all of
the info shown in the example at right. You can add this additional
information into an OpenAir file with a text editor using the following tags.
After doing this, make sure you process the file with the OpenAir2faf
program so it can check your entries and give a warning if typos or mistakes
are found (see section 7.2).

If the airspace name in the OpenAir file has more than 16 characters, the last character is truncated and a serial
