Why don’t we fly DC-10’s anymore?

the Douglas DeCompression-10 was a mistake

ETOPS.

Anything with more than two engines is haram

>>2051321
We've become too good at building engines, it would've been cool to see modern trijets, but we're doomed to see twinjets for the rest of time, at least until someone manages to cheat physics/engineering/economics.

>>2051315
Death Cruiser 10, followed by More Death II

>>2051317
This. As impressive as the death cruisers and tristars were close up in the hangar, or lined up together waiting to go on stand, they were always on a countdown.
I suppose they're like looking at photos of those old steam ships that also had full canvas rigging, in a way. Not as obviously technologically transitional, but definitely of a particular timeframe.

Love this livery. I think the first flight I took was Airtours Airbus of some type (although the internet doesn't seem to think they had Airbuses in the 90s) to Spain. Think I was 5 or 6.

I wish we had gone with the original Trijet 777 design.

>>2051378
They did very late 90s, partly courtesy of spotters sites and also because I started there around 2000 and there were some early msn A320's and 21's there already (looking at some of those registrations is a trip down memory lane) to say nothing of the lower-deck-lav A330s (who were global fleet FH leaders up to TCX going bang; the old girls were still trucking away happily)
An anecdote in the spirit of the thread. Pull up a toolbox, lad.
The 3 DC10s were all due to go out of service on the same day. One last set of flights, and then adios. BYDA, TDTW (aka Tinky Winky) and DPSP (Dipsy) had other ideas. They effectively downed tools that day. "Get rid of us, will you? Right. Sod you.". All three went tech before their early morning flights, had maintrol and flight ops both tearing their hair out as they tried to sort out the consequences of three sulking widebodies all day, and they didn't move till I saw them taxi out as I pulled out the car park myself to go home late afternoon. Full day of delays. Ouch. Fortunately I don't THINK we had EU261 at the time. Now in fairness, the reliability of those old jets was partly the reason they were getting offloaded, but I did find it darkly amusing they'd gone for collective action.

Is it less fuel efficient?

>>2051326
I want to see a unijet with an extra-wide-bypass turbofan the diameter of the fuselage, feeding from ducts to the top/side and discharging from the rear + limited thrust vectoring

>>2051525
and I want every plane in passenger service to continue to have minimum two engines.

>>2051314 (OP)
tri engines are dangerous as fuck

>>2051314 (OP)
The youngest one(s) are 36 years old. The company that made them went tits up. There were a couple of high-profile vehicle failures that led to a massive loss of orders and payouts to the estates of lives lost. I'm not even a pilot or aviation enthusiast and I know this. Let someone who can tell you how shitty they were give a more detailed explanation.

>>2051367
so many memories of being delayed for hours and hours with these glorious bastards

>>2051525
NIMBYs always whine when new aircraft types appear.

Would the rotodyne have been successful if it had the main rotor driven by another set of turboshafts instead of tip jets?

>>2051801
Probably not because someone from Lockheed would have bribed people to buy their sh1t instead.

>>2051741
I like this thing because it looks so spiteful towards nature and the laws of physics. It's lifting straight up with that rotor because fuck gravity and fuck being a plane, and it's going straight forwards with those propellers because fuck being a helicopter.

>>2051525
ducts won't do on a modern high bypass engine, it needs that big cavernous intake to have efficiency

>>2051895
file fell off

>>2051314 (OP)

You only need two engines to fly over the ocean now.

(Despite the early problems, the DC-10 is rock solid. They're still flying for FedEx.)

>>2052023
Inverted occasionally with a madman loose in the cockpit.
Take care airplane dudes.

>>2051314 (OP)
no concordes left to kill

>>2051314 (OP)
Humans cannot compete with AI when it comes to engine placement design. You only need 1 engine.

>>2051326
you one need 1 engine

>>2052023
FDX retired their DC-10 fleet (converted to MD-10s) in December 2022

>>2052220
Nyet, comrade. More engines better.

I have a random question to ask, so I’ve been watching videos about cascading failures that lead to crashes in commercial jets. It has me wondering, does the aspect of having so many automated systems inhibit pilots ability to respond to situations where flying the plane manually and technically is demanded?

>>2055272
>inhibit
As in, preventing them from flying the plane? None I think except for the MAX crashes. But the fact that they get less time flying manually probably makes them less capable of responding to emergencies.
In the end, all of those systems are in place to prevent the plane from entering in one of those situations in the first place; preventive rather than corrective. Safer to not let a plane get out of it's flight envelop.
Think about it like this: Does a car with a bunch of safety features prevents a driver from responding in case of an accident? You could say that a professional driver could get out of a bad situation without ABS for example, but it's better to just never let a vehicle be in that sort of situation to start with. Cascading failures are rare, they do happen of course, but having so many systems is what makes the average flight safe.

>>2055272
There was a notorious crash in the late '10s of an Air France Airbus that crashed because the pilots lacked basic flying skills due to the high degree of automation. I think it stalled and crashed from a high altitude.
I believe training has been altered to put more focus on fundamental skills.

>>2055288
>Does a car with a bunch of safety features prevents a driver from responding in case of an accident?
Funny you mention this; there was a video circulating of a car stopped on train tracks that couldnt get moving because the door had been opened and modern cars with fully electronic/"fly-by-wire" gear selectors refuse to engage 'Drive' if the door is open

>>2055272
half the brown skin thirdworld pilots dont even know how to fly, big commerical planes opperate almost exclusively on auto pilot and the 'pilot' is just there to take the blame when a system fails and everyone dies.

>>2051315
Elaborate

>>2055333
>and modern cars with fully electronic/"fly-by-wire" gear selectors refuse to engage 'Drive' if the door is open
Depends on the vehicle. My C8 will go into gear with the doors open. But I suppose it's also a 500hp sports car and lacks modern driver assistance features to begin with.
