Requirements for Interference-Tolerant Radio Altimeter Systems
Summary
The Federal Aviation Administration is proposing new rules to make airplane altitude measurement systems more resistant to radio interference, which could come from wireless networks or other electronic devices. This helps ensure planes can accurately measure their height above the ground, especially during landing, which is critical for flight safety.
Key Points
- 1Airlines and aircraft manufacturers must upgrade radio altimeter systems to withstand interference from 5G wireless networks and other radio signals
- 2Radio altimeters measure how high a plane is above the ground and are especially important during landings and bad weather
- 3The FAA is concerned that interference could cause these systems to give wrong altitude readings, creating safety risks
- 4Airlines and manufacturers have until the deadline to submit comments on whether these requirements are practical and cost-effective
- 5This is a proposed rule, meaning the final requirements may change based on public feedback before the FAA makes it official
