The NAT track system has always been based on wind, although perhaps not directly. Tracks were drawn up based on airline preferred routes and the day's minimum time track between EU and North America. The preferences were averaged out and published.
Question for trans ocean pilots: Why aren't GPS and SAT phone used for trans ocean tracking instead of HF communication?

Check this link, both can be used. I have a friend who flies a Citation XLS across the Atlantic and the aircraft has HF but they always also carry a Sat phone if the HF Com is not good.

The last time I flew the NAT (2006) we used FANS. Future Air Navigation System. It was nice not having to make position repots on HF.

The aircraft, structure, wings, etc., only "know" indicated airspeed which the pitot tubes measure. At cruise altitude the stall speed increases which defines the minimum airspeed, and the maximum airspeed is defined by the maximum mach number. These change with temperature and pressure. On the primary flight display the indicated airspeed strip is overlayed by minimum and maximum airspeed bars so the pilot can see in real time the narrowed flight envelope at cruise altitudes. Indeed the airspeed is typically set for best fuel economy within the indicated airspeed limits. I hope that helps.

just curious, how big is that envelope at like 30,000 ft ? at 40,000 ft ? and at sea level ? roughly...

Check this link for the 737...

Forgot to add that therefore the headwind va tailwind only affects ground speed and therefore the flight duration since the airplane is flown within the at cruise altitude narrowed indicated airspeed envelope.

DO pilots throttle back when having strong tail winds or throttle up with strong headwinds?
I remember having 200knots headwinds coming back form europe to the east coast. The 727 couldn't make it and a stop in gander for fuel caused everyone to miss connections.

See my post a couple posts above for the complete answer. Headwind vs tailwind in practice only affects flight time as the airplane is typically set for best economy within the stall and maximum mach number limits.

Sailing has used wx and passage planning for decades. No need to fly just takes a few weeks and a boat. Gretta T would be so proud. Gore should put his mouth where his money is at sea level and drink thus reducing ocean levels while the earth is entering it natural cooling cycle.

Interesting. I wonder how that will affect traffic and safety?

So does the atmosphere lose more or less heat on a clear day? I’ll bet more!

Who has Gretta Thunbergs number? This is important!!!

Greta has your number Recor10 and she goes by her real name unlike cowards who don’t.
