Hi Pilots,

So, as you can see by my nickname, I am not a pilot. However, I have a very specific question about EFVS, EVS, and landing with such technology.

I've read some articles about EFVS, so these are my current assumptions (please let me know if I am wrong):
So there have been several airplane manufacturers like Bombardier, Gulfstream, and Dassault that equipped their newest airplanes with HUDs and EVS from Collins or Elbit. As I've understood it, HUD and EFVS are very common in military aircraft, but up until a couple of years ago, it was not common for a Gulfstream to be equipped with such a system. The benefits are enhanced vision in CAT3 weather (I hope that's the correct category for bad weather; I mean, like really bad weather with minimum RVR). I understand that it may make sense to equip private jets with such technology as they may land in airports that don't have other safe landing infrastructure.
I found that EFVS is part of the FAA regulation: https://drs.faa.gov/browse/excelExte...dalOpened=true
However, I don't understand if EFVS will be mandatory for big commercial airplanes like the 737NG or 737 Max. Unfortunately, I could not find any information on whether 737s are already equipped with EFVS.

My questions:
Is EFVS mandatory in the States or in Europe?
Do you find any benefit in using EFVS while landing?
Are there other systems onboard that provide you with the same safety and information as an EFVS? (Like, do you really need it or is it just a gimmick for bad weather if you are about to land at a local Chilean airport?)
Do you think airlines see a benefit in EFVS?
Would retrofitting a 737NG fleet with EFVS even make sense?


Thank you in advance for your support!
Nick
