“Flights get longer as planes get faster,”

BBC News reports

• air traffic is growing, that the airport resources cannot keep up with the demand;

• airports are becoming the bottleneck of the air transport network;

• with the increase in traffic, the workload of operators and planners is increasing

as well making their task of ensuring safety and efficiency harder every year;

• consequently, passengers start complaining, because their flights take longer

and delays are more frequent than ever.

Situation:

Problems:

• problems are related to the inefficiency

of daily airport operations and the non-

availability of reliable information;

Up-to-date information

All airport partners lack up-to-date global situational awareness due to

inadequate por fragmented information flows.

Reasons:

• Most relevant information exists somewhere around the airport in

various systems, but is not readily available to all partners;

• The information systems of the various partners have been developed

and built independently;

• Certain partners are reluctant to share information which they consider

“commercially sensitive”, therefore restricting information sharing.

Solution:

A-CDM – Airport Collaborative Decision Making:

What is CDM

A-CDM is a concept, which

encourages involved partners to

practice a more efficient and transparent

cooperation to enhance the Air Traffic

Flow and the capacity management at

an airport and en-route.

CDM elements and milestones

First elements of A-CDM

Target Off-Block Time (TOBT):

The TOBT represents the estimated time, when the aircraft is expected to be fully ready for push-back and/or

start-up upon reception of the according clearance.

This time is issued by the Handling Agent or Aircraft Operator and can be considered as a sort of agreement

for the ready time that all partners aim to achieve.

It plays an important role for the ongoing departure planning of the flight.

Target Start Up Approval Time (TSAT):

The TSAT is a calculated time considered by ATC planning systems, at which a flight might expect push-

back and/or start-up clearance, in order to achieve an optimized over all departure sequence.

Therefore all contributing factors from the airport (OPS concept, demand, deicing, Variable Taxi Time, etc.)

and restrictions

from ATC are considered and taken into account.

Agree on Information sharing and the way it will be delivered

• GAP analysis;

• WEB platform;

• internal systems (AMAN, AODB…);

• ……..

First elements:

TOBT & TSAT can solve queuing

Average aircraft consumption during taxi 20 kg/minute

55 minutes * 20 kg = 1100 kg

Optimistic JET A1 price is $1000/tonn

This morning AIRBALTIC

lost approximately $1100

Just taxiing…..

Annual rough

Rough calculation:

• 60 minutes * 365 days = 21 900 minutes;

or

• 21 900 minutes * 15 kg fuel = 328,5 tonns of fuel;

or

• 328,5 tonns * $ 1 000 = $ 328 500

• Only in pre-departure queuing

Daily observations show that 3 - 6 aircraft are

waiting in queue 4 - 5 times a day. Which give

us estimate of 60 minutes waiting time

everyday.
