Content • Human Factors • Impact on aircrews • Training Issues • Onboard Systems • Automation • Main new airborne functions • Technical Issues • Integration into Airbus Architecture • Integration of ASAS HMI into Airbus Cockpit • Evolution of Airbus Architecture for Package 1 • Research Status and Activities • Industrial Roadmap ASAS-TN 3rd Workshop - Airbus ASAS Status
ASAS - Human factors • ASAS HMI - What to present to the pilots? - What not to present? What range? - Which display? - How to correlate TCAS with ASAS? - How to process conflicts? Procedures? • Addressed in research programs • HMI & ergonomics Do Not separate traffic display from ASAS • Important impact on pilot task sharing, then procedures We are still a long way from transfer of responsibility from controller to pilot. • Could have important impacts on recurrent training for specific qualification ASAS-TN 3rd Workshop - Airbus ASAS Status
ASAS – Impact on aircrew • No ASAS application will be certified if it requires particular skills / physical condition of the crew Execution of the application should not be an issue • Crew workload should reasonably be contained by design of the applications. Even if average COM workload decreases, NAV/SURV workload shall be contained by design application and appropriate airborne automation. • The new tasks arise many and important safety questions. Crew acceptation needs: • Enough crew experience on lower level applications • A strong validation of the ASAS concepts • Possibly, a new legal frame (see below) Current procedures With ASAS Communication tasks Manoeuvring tasks Manoeuvring tasks Communication tasks ASAS-TN 3rd Workshop - Airbus ASAS Status
ASAS – Training issues • The (new) ASAS tasks will add to the existing ones, for which the type qualification requires about 5 weeks (except X-crew considerations) • Each new ASAS application will require additional training time and, sometimes, specific training means (ex : traffic simulation) • This additional time will depend on • The complexity of the application • The crew / machine task sharing (automation once again …) • The consistency between the ASAS applications and, for a given application, between the several places it can take place (this highlights the importance of a good operational concept) • The global consistency of the CNS/ATM applications ASAS-TN 3rd Workshop - Airbus ASAS Status
ASAS - Onboard Systems • ASAS shall not interfere with Safety Net (ACAS) • Media for Datalink Broadcast : Lobbying pollutes the work • 1090 ES FIRST - Promoted worldwide • VHF band not suitable for Air Transport, L-band more appropriate (UAT) • Additional sustainable link when needed • Traffic Display & Controls integration into the cockpit : Main focus on Ergonomics & Retrofit • Systems integration : Avoid changing deeply the existing aircraft architecture • Automation will be needed for spacing, then for separation applications • Begin by simplest procedures not requiring strong modifications • Standardisation : Importance of US / Europe joint work • Certification : Work early with Airworthiness Authorities ASAS-TN 3rd Workshop - Airbus ASAS Status
ASAS - Automation Most (if not all) ASAS applications involve, either repetitive, routine and / or very accurate new tasks related to guidance / navigation relative to other aircraft. Those new tasks may hardly rely on the sole crew using their CDTI Concerning the ASAS applications, the automation will address • Efficient filtering of displayed traffic information (including correlation of TCAS / ADS-B / TIS-B information) • Integration of ATC clearances (from loaded CPDLC clearances or from crew inputs) in the systems • Generation of alerts when ASAS applications are / will be impaired (in addition of possible TCAS alerts, that by design should never happen) • Generation of guidance cues (speed…) • Execution of the navigation / guidance separation clearances The automation considerations highly impact the design of airborne systems ASAS-TN 3rd Workshop - Airbus ASAS Status
ASAS – Main impacted airborne functions • ASAS applications management (including HMI) • ASAS customisation functions (incl. Custom. of HMI functions) • ADS-B data computation / reception / transmission / media management / TIS-B reception and management • TCAS / ADS-B / TIS-B data correlation • Traffic filtering and display • New Navigation / Guidance functions : • Longitudinal separation acquisition • Longitudinal separation maintaining • Predictions of lateral / longitudinal / vertical separations • Computation / implementation of overtaking offsets • Guidance for lateral crossing • Computation / implementation of overtaking step alts • Conflict resolution based on modification of 4D FMS trajectories • … • Computation of separation alerts • Reception / processing / display of dedicated CPDLC clearances ASAS-TN 3rd Workshop - Airbus ASAS Status
ASAS – Technical Issues • HMI • Display of the useful information of numerous aircraft in the selected range together with F-PLN, WX, terrain information • Definition and location of HMI controls (both dedicated and MCDU-accessed) • Consistency of design across all ASAS applications and, beyond, consistency of all CNS/ATM functions • Traffic data (TCAS, ADS-B, TIS-B) correlation • Complexity and accuracy of new functions • Criticality of new Navigation / Guidance functions • General • Latency of information (highly dependent on the architecture) • Equipment class • Software level • Compatibility with existent or future functions • Costs ASAS-TN 3rd Workshop - Airbus ASAS Status
Integration of ASAS HMI in Airbus cockpits (NUP I) specific guidance modes and parameters integrated to current controls & displays • Traffic display • Application identification • Parameters to control the current application • Surveillance & alerting Dedicated ADS-B & TIS-B controls Specific, loadable Data-link clearances Management of ASAS functions & traffic display ASAS-TN 3rd Workshop - Airbus ASAS Status

ASAS – Airbus R&D Status • Within the framework of European programmes, Airbus is exploring the operational conditions of ASAS implementation, addressing: • ASAS applications requirements and procedures, • The cockpit installation, HMI, and • The avionics architecture. A number of major human factors issues remain to be solved to enable safe operation on a routine basis . A follow-up programme (Collaborative-ATM) is expected to lead to operational trials in the 2007/8 timeframe. ASAS-TN 3rd Workshop - Airbus ASAS Status
