Transcript of Modern Cockpit
Balancing between tasks
monitoring multiple different sources of information of varying relation
Advances in the Cockpit
Human information processing
John Schaefer, Matt Hurley, Bryan Gagnon, and Cory Grady
FAA AC 20-175
- Increased traffic congestion
- Complexity of transport aircraft
- To increase safety
- 1979 in the MD-80
Flight Deck Modernization & Touch Screen Technology
- Boeing 757, 767
- 2-crew glass cockpit
- Commercial aviation: Boeing 767 in September 1982
Finger Size & Icons
- Liquid crystal display panel
- Found in most commercial airliner cockpits today
"the input device is physically part of the display area"
- 2005, glass cockpit was introduced into general aviation
- Models include Piper Arrow, Cirrus SR22, and Diamond DA-40
Three Touch Screen Requirements:
1. finger positioning
2. scratch, wear, water
3. predictable & obvious
Improved performance BUT Created new challenges
So what's the problem?
Challenges to overcome:
greatest amount of information in a limited amount of space
critical information = minimal visual scan.
On the Defensive
Touch and Hold
Human Factors to Overcome
perception, attention, and memory.
learning new systems
Too much information over wide viewing area = detrimental to flight
grouping relevant information together prevents processing stress caused by memory overload
Ex: VSI next to altimeter on PFD
