So re aircraft age: does EASA have different rules? The car analogy only works so far - planes are vastly more expensive, and thus must have a longer lifespan

So re aircraft age: does EASA have different rules? The car analogy only works so far - planes are vastly more expensive, and thus must have a longer lifespan (not to mention they're also designed and maintained to this end).

I think EASA usually agrees with the FAA about what equipment is OK. The FCC on the other hand expects electronic gear to not emit interference outside of its band and also that it should not be disturbed by EM activity outside the band. The FCC can put sanctions on manufacturers for this. The 737 is a unique case of an obsolete aircraft with a few problems: (1) Obsolete mechanical control system. If the 737 were fly by wire they could have made a system like MCAS that was safe. (2) Wings too low to the ground making it hard to fit high bypass engines (3) Struggles to take off even under good conditions because of wing geometry. When you hear that it is too hot in Arizona and planes can't take off they are saying that the 737 can't take off. (4) Circular cross section that is unergonomic. It is is an amazing experience to ride in the E195 or A220 which is a smaller plane than the 737 but feels like riding in a widebody. If passengers had any choice in the matter at all they would never ride on a 737 given the choice. There are numerous structural issues in the industry that have kept these superior planes out and kept the inferior 737 going strong. Boeing probably plans to make a starship for NASA in 2070 but they have no plan to replace the 737 and that's a problem.

  >> When you hear that it is too hot in Arizona and planes can't take off they are saying that the 737 can't take off. The CRJs and ERJs are usually first to hit operational temperature limits, not the 737. Edit: Also Boeing did have a 737 replacement project, but airlines did not sign on to that project and instead wanted another 737, so thats what Boeing gave them. https://en.wikipedia.org/wiki/Boeing_Yellowstone_Project https://en.wikipedia.org/wiki/Boeing_Yellowstone_Project
