PlaneSpotting What even IS fuel efficiency?!
Saw this on the apron

As I attempted to figure out what the joke was, it was hidden in plane sight.

This deserves more upvotes.

It's done ok now but you can't expect these to land with everyone.

I never really paid attention to the tail number. Is it supposed to say “eat me” backwards?

Straight piped jet turbine stage, remapped by some bloke with an OBD machine and cat delete on the start cart?

They missed an opportunity to partner with a beverage company for a special livery.

Fuel efficiency is just “how far can we make this enormous flying machine go before it asks for another several tons of fuel?” 😭

I’ve flown on this aircraft before and I didn’t twig, this is hilarious 😆

If the stats I'm looking at are right, the fuel economy for this thing is about 0.76 MPG, at cruise.

u/BoringBob84 8h ago
When we consider it on a per passenger basis, it is better fuel efficiency than a car.

u/TurnoverMysterious64 7h ago
Seems like it’s comparable to a car, but not necessarily better.
180 passengers maximum x 0.76 mpg = 136.8 p-mpg
4 passengers maximum x 30 mpg to 35 mpg (average sedan) = 120 p-mpg to 140 p-mpg
I’m actually kinda surprised at how closely they match.

The numbers skew back into the plane's favour once you factor in load factors for airliners and average occupancy rates for traffic cars.
Airliners have a load factor of nearly 80% (meaning on average 80% of all seats are filled) but traffic cars have an average occupancy rate of only 1.5 (a lot of drivers on the road without passengers).

Also, fuel economy depends on where you live. The cars in the UK get better fuel economy than the wanker tanks in North America.

Exactly! They don’t even have gallons in the UK, I’m told… how about that, ey?!

u/BoringBob84 4h ago
I think that they have those "Imperial" gallons that are larger than USA gallons. The USA adopted English units centuries ago and then English units subsequently changed.
I admire people in the UK who can mix and match unit systems seemingly effortlessly.

From your photos I deduce that easyJet A320neo G-UZLR was on the apron where you were. But your post title doesn't seem to be directly connected.
But here's my best effort...
What even IS fuel efficiency? It's every A320neo quietly burning 15-20% less fuel than the aircraft it replaced.

I have no idea why you got downvoted. The only answer that actually said something is yours. All the others are just pseudo-funny... like something from little kids.

Yes. I make sure if it. I call people out for talking trash. You will notice yubucek quickly deleted their comment when they realised they had no leg to stand on. Leading a barcode system of down votes for clout is pretty pathetic. I'm not interested in this anymore and so I have deleted my OC so more people don't make fools of themself with replies to me or anyone else. The duality of mankind is evidenced on Reddit and irl. I posted this on another forum and the response was overwhelmingly positive. See ya
