| Summary: | Purpose: This study hopes to suggest a proposal to install an aural warning and
automatic go-around system on Airbus aircraft to prevent controlled flight into terrain
accidents due to unstabilized approaches occurring below 1,000 ft.
Methods: It is analyzed by gathering surveys from aviation operation Airbus 320
operating flight deck experts to find the criteria for the operation of auditory warning
sounds and automatic go-around devices.
Results: Senior flight experts responded about the conditions for a warning altitude
at which an Airbus aircraft should go around by an audible warning sound, and an
autopilot system to operate during an unstabilized approach, which requires the pilot
to perform a go-around through an audible warning sound from 500 ft or lower.
Conclusion: Results are shown for the unstabilized approach warning conditions
that automatically lead to a reversal as follows: (1) Speed deviation: –5 kt/+15 kt,
(2) Descent rate deviation: 1,200 ft per minute, (3) Instrument landing system (ILS)
approach glide slope deviation: +/–1.0 dot, (4) ILS approach localizer deviation: +/–1.0
dot, (5) Bank angle deviation: 10°, (6) Thrust idle duration: 5 seconds. |
