An evacuation checklist that takes 50 seconds to complete with a wing full of fuel on fire...???Pilots must complete evacuation checklists, these often take 30/40/50 seconds or more to complete before an evacuation order is given
Even the most complicated checklist doesn’t take 50 seconds to read.
You’re not honestly suggesting people are going to wait calmly in their seats waiting for an instruction to evacuate a burning aircraft? Normal rules of engagement don’t apply in a fire situation, you have to act fast and take control of the situation before panic sets in and passengers take matters into their own hands.0 -

The flight deck crew need to gather information, assess the risk and whether that of an evacuation is greater or lower than keeping everyone onboard (an evacuation is going to lead to injuries and dumping people on an active taxiway with aircraft moving around is a huge threat to safety when people start running around randomly). Assessing the situation in the cabin and from the viewpoint of the cabin crew is of course part of this and you can hear a call from the flight deck to the cabin in one of the videos.
Once the decision to evacuate is made then the checklist is actioned, and while I haven't ever timed it, it takes an age for the flaps to go to 40 (the fully extended configuration) which is a part of the evacuation checklist on a 737 as the flaps are required to enable safe use of the overwing exits as they effectively create a slide rather than a 10ft drop. Only after the aircraft is configured for an evacuation will the crew then initiate it.0 -

Your instinct, while perfectly normal, is dangerous and could result in more injury and death than the fire itself. There's a reason why flight crew are trained on evacuations and why passengers are expected to follow their instructions instead of panicking and doing whatever comes into their head.
Left to their own devices, people would evacuate into the fire (people do the damnedest things when they panic), in front of a running engine, into the path of approaching fire engines, climb all over each other, freak out because the person opening the door is taking too long, freak out because someone is collecting their overhead luggage, freak out because they can't find their own overhead luggage, slide down the side on top of someone else, slide down with high heels and a plethora of other dangerous things. In an emergency, the last thing you want is people panicking and thinking for themselves.0 -

No im not suggesting people will wait calmly in their seats while the plane is on fire, they won't!And I know that! But that doesn't change the fact checklist for excavations can take up to a minute to complete. As has been explained above0 -
