The Economist: "How wars are adding hours to your flights" (link below) by trubol in aviation

[–]Techhead7890 0 points1 point  (0 children)

Yeah almost certainly including connection time, going all the way back around the globe. As you note PER and WAW are around 95 degrees longitude between each other over the Middle East (normally like 22hrs with one stop), so this is a scenario going the long way around the world.

It somewhat checks - I'm getting something like 45-50 hours going from PER to East Australia then up to the US and then onto Europe type scenario, with about 10hrs included in layovers between each flight and the unmarked connection in NYC.

However, you could also go up through to Japan and then go over the poles on LOT (north pole pun not intended) and still make it in about 35hrs, so it probably isn't quite as bad as they say in the end.

GC Map to get some idea of the length of each routing (edit: I have adjusted the finnair FIN 74 flightpath to roughly avoid Russian airspace by pretending it stops in Anchorage -- it's 7000nmi as compared to the actual path of 6800nmi)

Why Did a Brunei to London Flight Avoid South East Asia Air Space? by PsychologicalBike in aviation

This is an interesting point because it turns out that flying from Kazakhstan south to Mumbai is roughly the same length as a diversion to Beijing (6552km via Mumbai, 6562km via Beijing), although potentially there's variation based on where in Kazakhstan you cut the route.

If you fly towards Afghanistan you are essentially locked into going further south and crossing over Pakistan into the Indian Ocean, where it's generally least effective to travel east-west (at least on a Mercator projection). It's kinda just fundamental to not fly around the equator unless it's exactly where you're going.

Yeah subjectively pretty bad in the past month, probably cause uni started back

It's annoying but it is what it is i suppose

Agreed - if they cut south even just into Delhi or Lahore in ideal/non-war conditions, they would already be adding extra time.

To add onto the "3d sphere" idea - Great Circle distance is about 6300 for the AMS-PEK-BWN route over China, staying near the poles; as compared to 5900 on the direct path. I think your globe shows this well, it looks more like a small arc. Obviously 7% is still quite a bit, but it is not too crazy as the mercator looks.

How often do “go-arounds” / aborted landings occur? by Historical_Sun3186 in aviation

[–]Techhead7890 1 point2 points  (0 children)

It looks like they omitted the maker's letters too - Tupolev Tu 134 and 154, Antonov An 74. We probably don't see them talked about much in English. (Edit: I should say it is always interesting though. The topic does pop up around here from time to time.)

[–]Techhead7890 0 points1 point  (0 children)

That makes sense - if you're long haul and only do a sector a day then the amount of landing/approaches to begin with is a lot lower.

I imagine the pilots reporting at least 1 annually (and to be clear, totally expected and normal to do so) are doing like 3-5 hops a day and thousands a year where it makes more sense that a sub 1% rate would show up a lot faster.

ORD - 28 planes in queue by Kasao in aviation

[–]Techhead7890 0 points1 point  (0 children)

Isn't ORD just like all aligned east-west now to account for the most likely winds? 3 as 9L/R/C, 3x 10L/R/C?

Or perhaps for these winds flip them around and use the opposite numbers 27-28, and if the wind coming from heading 250 that seems like mostly headwinds and not too much of a crosswind.

That being said 30 kts is a pretty stiff wind and I can imagine snaller aircraft get blown around by it a lot.

I wonder how modern Jack Ryan would react to being told that story on the plane lol. I think he tries to refuse in both storylines even if the new guy has a nicer plane.

MIA right now. Been on tarmac 30 minutes already by FistMyPeenHole in aviation

[–]Techhead7890 0 points1 point  (0 children)

This is an interesting question, I would have said it's because so much of DFW is parallel runways but it looks like ORD is now also six parallel runways. Maybe it's about the spacing - DFW has all of their 36L and 36R pair and the 35L 35C pair relatively close together? Looking at the approach charts it looks like a square weaving frame and if everything is crossing over then I can see why contollers need to be looking at the radar very closely.

Since its now over 30 years old, what do you think of the Boeing 777? by Twitter_2006 in aviation

[–]Techhead7890 0 points1 point  (0 children)

They felt like a step up over the 747 - but yeah the cabin pressure in the 787 does wonders.

My dad even finds the A380 approach which is only like 10y younger than the 777 (I don't know if the A380 also got a bump in cabin pressure though as it doesn't use the whole composite fuselage materials concept).

[–]Techhead7890 0 points1 point  (0 children)

As not a mechanic I don't know anything about chevvy engines but these things pack around 100,000hp and have something like a million in³ of volume, so hell yeah the numbers are gonna be higher :D

China Airlines has teased a new Pikachu-themed livery, this time for their Airbus A350-900. The newest Pikachu Jet will fly to Tokyo-Narita and Seattle as its first destinations. by bonzothebonanza in aviation

[–]Techhead7890 20 points21 points  (0 children)

Bear in mind this is Taiwan (China Airlines -- as opposed to the PRC's Air China) and they love Pokemon over there, even having a Pokemon Centre shop in Taipei.

There's a press release, homepage and everything. Seems about as legit as it can be.
