Aviation and 5G interference

    I know there are some very knowledgeable people here, so I thought I’d ask about this, since I can’t make much of it

    There are many headlines from the US about this issue today (and yesterday)

    Top US phone firms agree delay of 5G rollout

    “Plane makers have warned that C-Band spectrum 5G wireless signals may interfere with sensitive aircraft electronics and could disrupt flights.”

    It’s summarised well by Ben Schlappig here:

    Airline 5G drama?

    and Charlie Page is a Senior First Officer on the Boeing 787 Dreamliner. He has a very detailed piece on it, but it doesn’t address why this might be a problem in the US but not here – unless it’s a different 5g?

    5G signals are having an unexpected side effect on aircraft operations – here’s how pilots are dealing with it

    … or is this really just a difference between the US and Europe with regards to regulation, like with certain drugs?

    Interesting update from our US edition

    FAA Announces 5G ‘Buffer Zones’ Around 50 US Airports

    Sometimes some people try to create a problem, most without any bad intention, but some are from vested interest.

    If any onboard passenger phone 5G signal could interfere with cabin electronics, that can be easily mitigated by a shield at cockpit door.

    Problem could arise from a phone uses by pilots.

    I understand even the latest fly by wire airplanes can be flown manually as long as the engines are running and hydraulic system for radar is good.

    I will be rather worried about increasingly high number of drone and laser uses that could affect during takeoff or landing.

    It’s not just the equipment inside the cockpit where signals could be picked up. Aircraft have various communications and navigational antennae located at various points around the exterior hull of the aircraft. As well as that, there are cables carrying control signals which run under and above the passenger cabin. While these are shielded, it’s theoretically possible that a strong signal from a radio transmitter close by could cause some degree of interference, although I think the risk is minimal.
