General Remarks
 
  • The flight plan MUST contain valid departure and arrival airports. If runways are defined then they MUST belong to the airport as read from the database
  • Empty lines in the file format must be present
  • SID/STAR/APP type waypoints are not to be used.
Specific Fields
  1. Waypoint name : MUST exist in the database
  2. Waypoint type there are two values 1 (Airport type) and 5 (Ordinary waypoint type)
  3. Position entries take the following form: 1 N 40.6398 W 73.7789 13 where the first number 1 means a valid position followed by latitude, longitude followed by the position altitude. For ordinary waypoints altitude is naturally not required and thus a value of zero is commonly entered. Airports only should have an altitude value.
  4. Restriction phase can be 0 (none), 1 (CLB), 2 (CRZ) and 3 (DES). It is important to set a non zero value for airports so that the remainder of restriction information can be read.
  5. Restriction altitude type can be "-" or A (at or above) or B (at or below) or W (at or above this altitude at or below the next entry). "-" for airports.
  6. Restriction speed (not required for flight planning)
As a general convention a value of -1000000 in any numerical entry signifies NO DATA (e.g. not restricted) and a value of '-' or '----' (any number of dashes) in a string entry means also NO DATA (e.g. runway id)
