2. OBJECTIVES

Título de la presentación Arial Negrita

| |27/06/201812

OBJECTIVES

❑ To Support Airport Operations Management by

developing a SIMPLIFLIED A-CDM for medium/small

airports.

❑ To allow the integration of these airports into the ATM

network

| |

Levels of integration

• Currently there are 3 levels of integration of airports with the ATM Network :

Problem statement :

“Can we create an additional category where full set of DPI messages is

manner” ?

A continuation from SESAR1

Concept initially tested in 2016 in ALC.

• “Results highly encouraging but more work needed”.

For SESAR2020 / PJ04.01

• Inclusion of concept as operational improvement step in the integrated

roadmap

• Robustness of platform significantly enhanced and User interface

improved

• Simplified pre-departure sequence

• All elements of milestone calculations re-visited conceptually and in

terms of inclusion in the platform

• Longer testing period

• Longer simulation period

• ‘Twin’ approach for both coordinated and non-coordinated airports

3. CONCEPT DEFINITION &

DIFFERENCES WITH CURRENT A-

CDM

Título de la presentación Arial Negrita

| |27/06/201817

WHAT’S A-CDM?

A-CDM is about collaboration between the different partners/stakeholders with a role

in the whole Turnaround Process of an aircraft at the airport. This involves ATC,

airlines, handling agents and the Airport Operator.

Focusing on:•Monitoring the whole process, the arrival to the airport, the turnaround process and

the departure.

•Sharing the most accurate information, at the right moment, with the right people to

act accordingly.

•Improve the data exchange between the airport and the ATFM Network (NMOC).

| |27/06/201818

A-CDM MILESTONES

| |27/06/201819

MAIN A-CDM CONCEPTS

• TOBT: It is the target time at which the company or the handling agent will have the

aircraft with doors closed, airbridge disconnected and ready for push-back.

• TSAT: It is the target time assigned by the local ATC at which the aircraft will be

authorized for start-up. This target time will have into considerartion the TOBT

ATFCM measures.

| |27/06/201820

A-CDM CONCEPTS

CONFIRMATION/UPDATE OF TOBT

• The company or the Handling Agent as a delegated task, will have to confirm the

TOBT 30 minutes before the departure.

• The company or the Handling Agente will have to update the TOBT when the

target time will be out of the +/- 5 minutes tolerance window

• The EOBT of the Flight Plan must be updated within a tolerance of TOBT +/- 10

minutes.

• In case the TOBT does not meet the those criterias, will be invalidated and the

aircraft will be removed from the sequence (invalid TSAT) and a new

TOBT/EOBT will be needed.

❑ THREE MAIN IMPROVEMENTS:

2. Optimise A-CDM Algorithm for Middle size Airports

➢ Move from Predictions based on “Time to” (Time driven) to Predictions based

on Aircraft Situation (Status: Event driven)

➢ Reduce number of milestones, eliminating those which add little value

- Boarding Type

❑ TWO MAIN IMPROVEMENTS:

3. Increase Automation to better Support Handling by using a

Statistical Model (Sensitivity analysis) to assess and calculate

the impact of different variables in taxi and boarding times:

➢ Typical Boarding Times

based on:

✓ Type of Aircraft

✓ Handling Agent

✓ Stand Type (Contact;

Remote)

➢ Typical Taxi Times based on:

✓ Stand and RWY in Use

❑ THREE MAIN IMPROVEMENTS:

3. Increase Automation to better Support Handling by using:

➢ Automatic TOBT Updates in case of:

✓ Boarding Alarms

▪ Add 5 minutes to TOBT if Boarding is delayed

✓ TSAT (Target Start-up Time) Alarms

▪ Move Flight from sequence if aircraft is not ready at Start-up Time

▪ Re-calculate TOBT and TSAT to the best possible departure slot

SUMMARIZING

- No need to update the FPL to the TOBT +/- 10 minutes

window

- Automatic TOBT calculations since FPL filed.

- TOBT updated manually by the handling agent just in

out of regular operations and/or when aircraft

removed from the sequence.→ Low handling agent

workload

- Improved departure sequence and TWR workload.

RESULTS

| |27/06/201834

When a TOBT value was automatically updated, was easy to

understand why?

| |27/06/201835

The anticipated knowledge of TOBT helps my reallocation of

resources?

| |27/06/201836

Knowing the departure sequence (TSAT) helps me in task

coordination?

| |27/06/201837

A-CDM does not increase the workload singnificantly

| |27/06/201838

I consider taht this concept is a step foward compared to the manual

entry of all TOBTs

| |27/06/201839

DMAN does not increase ATC workload

| |27/06/201840

TSAT data assigned by DMAN do no penalize with delays operations

due to incompatibility, or others, that could be solved by the

controller
