Research challenges examining normal operations Joris Field, NLR

Research Challenges

• Confirming underlying theories • Putting workgroup conclusions to the test • Developing & testing new practices

Why research?

• Realistic responses • Non-normal responses

Normal operations – easy?

Research supports Operational Expertise

• 99.9% • 0.1%

What is the perceived chance of a Go-Around...

Research Challenges

What is the problem?

Where does this come

from?

What can we do about it?

Manual Operations of 4th Generation Airliners

This research is funded as part of the FP7 2012 Aeronautics and Air Transport programme under EC contract ACP2-GA-2012-314765-Man4Gen

Where does this come from?

Normal Ops: Go-Around

Weather forecast – showers in the area

From 1000 ft: 30 kt tailwind introduced • Visible on ND • Unstable airspeed • A/T compensates

Heavy rain at Decision Height • Visibility reduces • Lose runway visual

ICAO LOC-I Symposium, May 2014 8

What do you measure?

• Instructor observers • Airbus Assessment & Grading System • ICAO Airline Pilot Competencies

Crew behaviour

• Actions • Eyetracking • Heart rate

Data Measures

• Interviews • Observations

Debriefing & Analysis

What happened?

Aware of the weather risk

• Updates • Diversion

Monitoring weather

• Until short final

G/A decision

• Loss of visual • Unstabilised • Tailwind

Crew behaviour Captain – Pilot Flying • Flight Path • Commander? • Overview?

First Officer – Pilot Monitoring • Communications • Flight Path? • Weather? • Aircraft Systems?
