Why do test pilots wear the full gear, helmet, parachute and all even inside something like a B787? Has there ever even been an incident where test pilots had to abandon an airliner (and lived)?

Test frames can have emergency hatches built into them just in case, since jumping out of a normal airliner door isn't really feasible - https://www.heritageconcorde.com/escape-hatches

The helmet probably doubles up as having an attachment for an oxygen mask (In case the airliner's brand new cabin air system fails) and stopping them from getting hurt on what will presumably be a rough exit through the hatch.

Oh, I see. That's interesting.

Airliner doors close from the inside like a plug going into a drain. If the door simply closed from the outside then the pressure differential of the low pressure outside and the increased pressure inside could blow the door off if there were any problems. With it closing from the inside and all that pressure bearing on it, that pressure differential works in the aircraft's favour and forces the door to stay closed, it should realistically be impossible for an average person to open the door whilst the aircraft is pressurised at altitude.

Can you explain what you mean by closing from the inside? All Planes I've flown closes from the outside and there have been instances where the doors have been opened midair. I'm just asking Im sure im just not picturing what you said properly

It's opened to outside, but you need to take it a bit inside to open i think.

 

[Picanha]

There are different door systems. Some swivel a bit inside so you can open it. Thats why you can open it to the outside.

An other concept is the door which moves upwards. Transport planes often have them for paratroopers to jump out.

Actually, that's a valid point - I've no idea about things like Dash 8s where the stairs are built into the door and sing open from the bottom. What I was trying to describe is what's in the opening 15 seconds of this video. Although the door swings in from outside, it then comes entirely into the aircraft and gets pushed out against the doorframe from inside - that's what I meant by closing from the inside.

Ah and the doors are centrally locked by the cockpit crew too...so even superman can't open the door

 

[Picanha]

I think he means the doors move from the inside to fit tight. Their inner diameter is larger than the door cut out from the ouside. Hence the swivel mechanism or the slide up mechanism.

 

[Gaz]

Yeah, badly and incorrectly written on my part - should have clarified that not all airliner doors work that way, but some them or a lot of them work that way.

 

[Junglejim]

Im looking at the Airbus and as far as i can remember its out and flush into the body, but it never actually goes into the body like the one in the first plane on your video. I guess thats where the confusion came from on my end. I saw other vids and it seems like a Boeing thing.

Airbus and Dash has no cockpit controls for the cabin doors. Only reason why they wait for the PA for "Cabin Crew you may now open doors and welcome to XXX" is because of safety knowing that the engines are all off, the ground personel are there and there are stairs or tubes ready to receive them

Genuinely don't know, though at the three minute mark in this video when the internal handle goes upwards, the whole interior side of the door moves up within the frame as well, before it starts to move outwards - makes me wonder if something is going on there in regards to getting in position to act as a plug door.

EDIT - I guess this is what Picanha alluded to earlier on when he said some doors move up.

 

[Picanha]

If you take a close look, you can see them move slightly inwards and upwards when releasing the locking hnadle.

I stand corected then. Just saw the doors page on the ECAM and thought you could lock them somehow. Ist just an indication then. But after looking a bit into it, it seems only emergency exits are lockable or non plug type doors.

What about the electrically operated doors?

Bell is pitching its Bell 525 Relentless super-medium-twin helicopter for an upcoming German Federal Police tender to replace the agency's Airbus H155 and H215 helicopters. Bell's programme manager Jonathan Castorena has told aviation magazine Fʟᴜɢᴇʀᴇᴠᴜᴇ that former members of elite unit GSG9 were brought in to help Bell design a cabin layout and mission deck ideally suited for law enforcement operations.

Taking on top dog Airbus, Bell says their product is more modern, more affordable and quieter than anything their rival has to offer. Relentless is also one of the fastest civil helicopters ever built, capable of reaching speeds of up to 370 kph (230 kph). Bell hopes to score a contract for fourty-odd aircraft. With a fleet of more than 90 helicopters, Germany's federal police is one of the largest civil helicopter operators in the world.

That's a nice looking chopper! ?

This triggers my OCD in ways I cannot possibly begin to describe.
