With regards to the 5G and 737's etc, it my understanding the possible interference only effects the "Rad Alt" (Radar Altimeter) because it uses doppler waves to measure the actual height above the ground, rather then the barometric altimeter which measures air pressure.
On the way into landing the Pressure altitude will be reset from 1013.2mb (the Americans use inches but 1013.2 is the WW standard when flying above 3000') to the airport QFE (altitude corrected for field elevation, ie the airfield is X amount of feet above sea level and the air pressure is currently......so that when the aircraft lands at the touchdown point on the runway the pressure altimeter will read 0 feet or very close) but on the approach it is vital to know the ACTUAL height above ground which is the Rad Alt. It's important primarily for landing in crap weather, reaching your MDH (minimum decent height) say 400' is when you make the decision if you are going to land based on if you can see the runway!
I believe it is this factor that many are worried that the stronger 5G signals can interfere with.
So, I guess the question is, how did 5G get as far along as it has without someone realizing this a lot sooner? It seems to me that this is a huge oversight on someone's part.
Pilot hubby says there's no way they didn't know about the effects of 5G long before this.
Why am I not surprised?
There's a FAA AD flight manual supplement regarding the potential interference of 5G signals with the aircrafts radar altimeter (I believe it became mandatory March 1st). The FAA tried to fight the 5G rollout due to possible problems but it was basically ignored.
Here is the FAA response:
