5G Airworthiness Directive on the Books for February 2024

New AD Demands 5G-Tolerant Radio Altimeters for Part 121 Operations Near Cell Towers

Carriers will need to equip their aircraft with 5G C-Band tolerant altimeters by February 2024 according to Airworthiness Directive AD-2022-01379. The newly issued AD supersedes 2021-23-12, which applies to all transport and commuter category aircraft equipped with a radio altimeter. The older AD requires revision of the limitation section of the aircraft's POH to incorporate limitations from operations from using radio altimeter data in the presence of 5G C-Band interference identified by NOTAM.

Graphite-Based Leading Edge Heating Element Shows Promise for Lighter, More Efficient Ice Protection

Qarbon Aerospace, finished their icing tunnel testing of the upcoming Helios Ice Protection System. The system uses a heated graphite layer embedded in a thermoplastic composite leading edge, harnessing the material's improved thermal conductivity to prevent ice buildup in flight. Thanks to the increased efficiency of graphite, the system comes up to operating temperature "significantly faster" than legacy ice protection systems, reducing wasted energy use.
