Summary
High-powered handheld lasers are increasingly aimed at aircraft, posing a significant risk of retinal damage to pilots. Aviation medical specialists must recognize this growing threat to aircrew safety.
Area of Science:
- Ophthalmology
- Aerospace Medicine
- Laser Safety
Background:
- Reports indicate a global rise in laser incidents targeting aircraft.
- Affordable, high-power handheld lasers (up to several thousand mW) are readily available online, despite restrictions.
Purpose of the Study:
- To inform aviation medical specialists about the risks associated with laser attacks on aircraft.
- To highlight the potential for retinal damage in aircrew exposed to specific laser types.
Main Methods:
- Review of aviation safety reports and laser hazard data.
- Analysis of laser power output and wavelength characteristics.
Main Results:
- Lasers with power outputs of several thousand mW have a nominal ocular hazard distance of approximately 1000 ft (304.8 m).
- Exposure at low altitudes presents a direct risk of retinal injury to aircrew.
Conclusions:
- Aviation medical professionals need to be aware of the ocular hazards posed by high-power lasers.
- The accessibility of these devices necessitates increased vigilance and awareness within the aviation community.
