Completing a Flight Plan
The diagram depicts a actual flight plan filled for the
flight ALK505 which departs from BIA(VCBI) to
London Heathrow (EGKK). The copies of the flight plan should be dispatched to
all the relevant Flight Information Centers(FIC) to make the flight possible at
the given times, routes and levels.
addition, for massagers transmitted over the AFTN, there are four characters
added to the indicator to determine the destination agency at the location. A
few of the usual ones are listed below:
