Fly like the wind: Pilots are about to cross the Atlantic in a whole new way

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?

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.

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.

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?
