E) LKMT EXCHANGES INFORMATION FOR DEPARTURE FLIGHTS BY APPLYING THE
ADVANCED ATC TWR PROCEDURES. MESSAGE EXCHANGE FROM THE LOCAL SYSTEM
TO THE ATM NETWORK COMPLIES WITH THE EUROPEAN STANDARD FOR A-CDM
AIRPORTS, USING THE FOLLOWING MESSAGE TYPES: 
A-DPI: ATC DEPARTURE PLANNING INFORMATION MESSAGE, FOR ALL
INSTRUMENTAL DEPARTURE FLIGHTS.
C-DPI: CANCEL DPI, CANCELLATION OF DEPARTURE PLANNING INFORMATION,
WHEN REQUIRED.
WHEN PUSH-BACK APPROVAL HAS BEEN GIVEN AND THE AIRCRAFT STARTS TO
EXIT THE STAND, THE TTOT IS CALCULATED AND TRANSMITTED TO NMOC VIA AN
A-DPI MESSAGE. THE USE OF THE VARIABLE TAXIING TIME INCREASES THE
PRECISION OF THE TTOT. 
AFTER RECEPTION OF THE A-DPI, DLA OR CHG MESSAGES THAT CHANGE THE
FLIGHT PLAN DATA SHALL NOT BE ACCEPTED. IF REGULATED, THE CTOT
ASSIGNED BEFORE RECEIVING THE A-DPI SHALL BE MAINTAINED. 
IF AN AIRCRAFT HAS TO ABORT TAXIING FOR TECHNICAL REASONS, THE TWR
WILL SEND A C-DPI MESSAGE TO THE NMOC. THE RESULT OF THE C-DPI IS
THAT THE FLIGHT SHALL BE SUSPENDED BY INFORMING THE OPERATOR VIA AN
FLS (FLIGHT SUSPENSION MESSAGE) WITH THE COMMENT 'SUSPENDED BY
DEPARTURE AIRPORT'. THE FLIGHT PLAN CAN BE ACTIVATED AGAIN BY
UPDATING THE EOBT WITH A DLA OR CHG MESSAGE.
