I fly airbus on jetblue I didn’t know they had to enter proper weight in order to take off that’s crazy. If the pilot gives full throttle it should go full throttle, why put a govenor on a plane ? To save some fuel mileage ? I believe there was an earlier incident where the airbus wouldn’t let the pilot fly the plane properly and crashed. Taking control away from the pilot and giving it to greenpeace carbon counters is a bad idea.

That's not how it works. You are talking about two different things. One is the onboard (I think it's a laptop for the A320) computer that does the weight and balance calculations. The same kind of calculations that decades ago were done manually on the ground. A pilot of a 1960s Boeing 737 also gets takeoff thrust recommendations. The only difference is that today the pilot can be given the raw data (e.g. just the weight / load for aircraft sections A,B,C and you're almost done) and do the stuff onboard, which saves time.

The other thing is flight envelope protection, which is a safeguard against e.g. intentionally stalling the aircraft in mid-flight. It only prevents actions that would threaten the structural integrity of the aircraft or make the plane fall out of the sky, not going full throttle on takeoff. Programming to slow an acceleration into the autopilot can of course be overridden manually.

This could refer to Air France Flight 296 or American Airlines Flight 587
