ALAR Objectives
•
To reduce the approach-and-landing accident (ALA) rate by 50% within 5 years of issuing final recommendations in 1999.
•
To identify equipment, operational, regulatory and training measures that will improve safety for aircraft from commencement of approach through circling, landing or missed approach.
Statistics for Approach-and-landing Accidents (ALAs)
•
56% of Western-built large commercial jet accidents are ALAs.
•
Approximately 50% of fatalities are the result of Western-built large commercial jet ALAs.
•
By 2010, the task force estimates 23 Western-built large commercial jet fatal accidents will occur annually.
•
Controlled-flight-into-terrain (CFIT) accidents are not showing a downward trend.
ALAR Data-driven Strategy
•
High-level analyses of 287 accidents
•
In-depth study of 76 incidents and accidents
•
Line observations on 3,300 U.S. flights
•
All conclusions supported by data
Most Common Types of Approach-and-landing Accidents
•
CFIT
•
Loss of control
•
Landing overrun
•
Runway excursion
•
Unstabilized approach These comprised 76 percent of the sample.

Nonprecision approach procedures Go-around decision Aircraft position awareness vs. terrain ATC awareness of aircraft position (continued)
A “Golden Rule” and Risks
(continued, #2) Communicate
• • • •
Pilot-controller communication Runway incursions Knowledge of traffic Flight data availability Manage
• •
Errors in conducting checklists Complexity of automation
Inadequate Situational Awareness in ALAs
•
Inadequate situational awareness was a factor in 51% of ALAs.
•
Currently available safety equipment was not installed in 29% of the aircraft in ALAs.
Factors in Unstabilized Approaches and Missed Approaches
•
42% involved “press-on-itis.”
•
36% were low and/or slow on approach.
•
30% were high and/or fast on approach.
•
Only 17% of crews initiated go-arounds.

Terminal Area Infrastructure
•
21% of ALAs involved lack of ground aids.
•
12% of ALAs involved lack of ATC equipment (terminal approach radar, minimum safe altitude warning).
•
The risk of ALAs during nonprecision approaches is five times greater than the risk of ALAs during precision approaches.
•
The risk of ALAs in the absence of terminal approach radar is three times greater than the risk of ALAs with terminal approach radar available.
Best Solutions for Today
•
The radio altimeter is an effective tool to help prevent ALAs.
•
Education is needed to improve pilot awareness of radio-altimeter operations and benefits.
•
Develop policy and SOPs for using radio altimeter.

Best Solutions for Today
(continued, #2)
•
EGPWS/TAWS for better terrain awareness and early warning.
(continued)
Best Solutions for Today
(continued, #3)
•
Implement MSAW or equivalent on all approach radars for ATC terrain warning.
•
Install and use correctly the radio altimeter for enhanced terrain awareness.
(continued)
Best Solutions for Today
(continued, #4)
•
Use all available approach guidance (including ILS, VASI and PAPI) for better vertical position awareness.
•
Use constant-angle nonprecision approach procedures (CANPA), and eliminate step-down nonprecision approaches.
•
Use a head-up display (HUD) with a velocity vector to provide projected touchdown point.
•
Use angle of attack, for energy awareness.
(continued)
Best Solutions for Today
(continued, #5)
•
VHF radio anti-blocking devices can improve communication.
•
TCAS should be installed on freight-carrying aircraft for better traffic awareness.
•
Airport Surface Detection Equipment to prevent ground collisions.
•
Flight operational quality assurance programs can identify unsafe trends.
Best Solutions for Tomorrow
•
Vertical situational awareness display for better terrain awareness.
•
3D/4D virtual reality synthetic vision for a VMC-like display in night, IMC conditions.
•
Precision approaches to all runways with satellite navigation.
(continued)
Best Solutions for Tomorrow
(continued, #2)
•
Terrain/navigation database integrity and accuracy for better position sensing.
•
Improved position sensing and airport mapping to prevent runway incursions.
•
Harmonization of avionics, charting and database to assure that all information is accurate.
(continued)
Best Solutions for Tomorrow
(continued, #3)
•
Improve autopilot human-machine interface for intuitive system control.
•
Improve FMS human-machine interface for intuitive system control.
•
Improve quality of FMS database for better position accuracy.
•
Use common/standard terminology for charting and FMS database for enhanced understanding.
