My pleasure fellow simmer!

hey I did a similar polar route this week which took me within 200 nm of the n pole and at aroud that point the aircraft started to gradually veer off lnav a number of times I had to correct using hdg select each time and as soon as the track started to lead away from the pole this stopped.

 

my routing

nearly 17 hours with mostly head wind

 

 

also magnetic heading selected automatically after 70 n and on the subject of true heading I noticed that real wourd 777 routes across oceans also switch to true whilst over the ocean ive seen this in 777 flightdeck dvds im not entirely sure why they would do this though........... anyone?

On thing I've observed is an odd phenomenom with regards to the fuel system: On polar routes, when the fuel temp drops low enough that the fuel freezes and the engines seize, I've noticed that the cold fuel actual causes the pilots and pax to begin sweating profusely.

 

I'll never understand it.

It's pretty obvious.

 

When the engines stop, they stop feeding the Packs with pressurized air.

 

The Packs need pressurized air to make the Air Conditioning work.

 

Even in cold areas, the inside of the cabin heats up rather quickly as there is no airflow. Indeed, over a very reflective surface like ice, the amount of light entering  the cabin windows will be increased, and with no airflow to remove any heat, a greenhouse type of effect begins happening, and the inside of the cabin warms up. Add several hundred warm blooded mammals breathing and moving around, and you have a rather warm cabin.

 

Standard mammalian physiology will cause sweating.

Radiation,

good luck. 

 

... and polar bears!

I've done about 4 or 5 polar route since the 777X released.  

 

Now not that it matters but I also check space weather as they do in real life.

Everything within that page can shows graphs or explains the info within the graphs and even has a calculator provided by the FAA to see how much radiation one might have over the course of a flight.

They misspelt Auckland as "Aukland" in one picture...

LOL, they sure did.  I'm always looking on the northern hemisphere, or really just other links within that page.

Tomorrow's galactic forecast: cloudy with a chance of meatballs...

I did that route just yesterday. PFPX said it would be 15:42h and it took me 15:40h (i got an visual approach...) and the fuel burn was within 100kg (!) of the calculated amount. AMazing combination of two awesome products!

btw, here an pilot of EK in a presentation about polar ops and what to do for preparation:

 

 

Have fun!

 

Just watched this video... Very interesting. I'll be saving this and I'm sure that I'll be watching it again.

I'm pretty sure if you don't have bleed air for pressurization then you would have bigger problems than cabin temps

I was just explaining the sweating, not the passing out unconscious. lol.
