Why can the pilot shut off the fuel during takeoff?
There may be a good reason to cut fuel to one engine shortly after takeoff.
You could have a system that prevents both switches being thrown, and only in the specific window after takeoff, but you’ve also now added two additional things that can fail.
This is a rather odd comparison. You can slam the brakes, yank the steering week, and do all sorts of things to intentionally make the car crash.
Commercial airplanes have safeguards against in-flight thrust reverser deployment. That is why they only work in tandem with the ground sensing systems - like the airplane must firmly believe both main landing gears to be physically on the ground for both reversers to be operational.
Also, you don't need multiple certifications and 1500 hours of experience to drive a car.
There's no handbrake to pull, and turning the wheel so hard to lose control is next to impossible. Maybe on an oily wet or loose surface.
New designs are prone to ill decision-making from engineers, drivers and pilots alike. Every pathway of let's do it differently is the beginning of a journey of fine-tuning loops until stability.
She was mad and said she has to jam it hard ( going for 5th and missed), but it went into reverse. And the gearbox literally hit the road when she let out the clutch.
The danger of a burning engine is irrelevant if you are heading into terrain.
Not quite. When you hit the ground you do not want any fuel leaks or hot surfaces as much as possible. That is why for example engines are shutdown when doing an emergency belly landing, to try abd prevent the airplane from bursting into flames.
Putting complex and fallible restrictions on safety-critical controls like fuel cutoff is usually a bad idea overall.
Engine oil leak has drained the oil completely and the engine is about to fail catastrophically (unlikely on takeoff but you never know).
Engine is on fire (out of all of the things that can go wrong with an engine during takeoff, this is very likely).
Engine has blown up (ditto).
Engine is missing from the aircraft (not likely, but engines have fallen from planes on takeoff before).
Debris / Ash / etc is in the engine (not likely).
Severe fuel leak (not something I'd worry about during takeoff).
Probably other reasons I can't think of.
Eventually, yes. Soon? Maybe.
Engine failure during takeoff.
Engine fire.
