Title slide: • Primary header:26pt Arial, green text, Maximum length: 2 lines • Secondary header:20pt Arial, black text, Maximum length: 2 lines Runway Safety – Aerodromes Ian Witter, BAA Airside Operations, ACI Europe
Incursions – Communications and Human Factors • Occur at aerodromes – involve ANSP, aircrew, aerodrome (driver) • Occur rarely due to equipment failures (“everything is serviceable”) • Communication is key • Aircrew believe it is okay to be where they are / where they are going • High risk events are low in number • Standardised Human Factors analysis needed • Identify the contributory factors • How can they be prevented?
Current Tools • Training – aircrew, ATC, drivers • Procedures – standard phraseology, read-back. • Layout - 6 layers of protection at holding points (“safety nets”) • Paint marking, centreline, stop-bar, signage, wig-wags, runway ahead.
New tools - Examples • Paris CDG – Runway Status Lights – 2 inner runways, installation • and testing underway, commissioning expected 2013/2014. • Milan – MXP – RIPCAS • DUB – Stopbar Violation • Monitoring. • “Rumblestrips” • “Ring of red” 24/7 stopbars Runway Incursion Alerting System Schiphol
Future tools? • Technology assistance • Smart technology – one aircraft is okay, next one is an incursion • Reduce the risk from an incursion • Monitoring role – computers better than humans at repetitive monitoring • Alert display to the aircrew – how? • Consistency of function – radar? beam detection? • Consistency of display? Many ad-hoc ideas occurring • TCAS – on the ground – flight-deck based system to prevent runway collisions
Excursions • Ensure correct runway data available (to enable ROPS) • Promulgate runway lengths, changes NOTAM, ATIS, RTF etc • Reduced lengths – ensure lighting, signage, markings reflect the changes • Maintain runway friction – wet / contaminated runway • Provide up to date information if contamination conditions are changing
Conclusion • Technology – monitoring and detecting conflicts • Output of warning – will it be standardised? When? By whom? • To whom will the warning be delivered – ATC? Aircrew? • TCAS – aircraft based collision prevention – Runway Collision Avoidance System? RCAS? • Standardised Human Factors analysis – to understand and learn the lessons, to inform risk reduction strategies.
