NASA Software Promotes Airline Fuel Efficiency
Is this really new? As a professional pilot for 40 years (1958-1998)
I was flying wind-favourable tracks across the Atlantic as long ago as the early 1970s. Alcock and Brown (1919) took advantage of favourable winds to make the first non-stop crossing. Jack |

No clue really, just taking a wild guess. rick jones -- I don't interest myself in "why". I think more often in terms of "when", sometimes "where"; always "how much." - Joubert these opinions are mine, all mine; HP might not want them anyway... feel free to post, OR email to rick.jones2 in hp.com but NOT BOTH... |

The winds certainly help; when I flew from JFK to Moscow on a Il-62 back in 1978, we were able to make the flight non-stop (they originally thought we were going to land at Shannon, Ireland, to refuel - but they caught a very favorable jet stream wind instead... more's the pity; that would have probably been the only chance I'll ever get to set foot in the home country) On the way back, we refueled at Gander, Newfoundland.

No clue really, just taking a wild guess. My wild guess is that this is the NASA PAO trying to justify their existence again, by hyping something as new that really isn't...like their forward-swept wing...and their scissors wing...and their ion engined spacecraft. |

Back in the early 90s I was on a nonstop from Seattle to Dulles on a 757 (which I generally loathe) and the pilot was chattering the whole way about the major winds aloft. IIRC, we made the trip, wheels up to wheels down, in about four hours or maybe a little more, so I guess he was right. |

Elsewhere I've heard it said that the 757 is "overpowered" - I guess something of a hot-rod of airliners. IIRC it was the 727 replacement, which if I recall correctly was not exactly pokey. Wikipedia says the cruise speed for the 757 is 530 MPH, and probably for for some time on either side of that ATC probably has them lower than cruise, so yeah, they probably got a good shove from winds. Just be glad you weren't travelling in the other direction rick jones -- Process shall set you free from the need for rational thought. these opinions are mine, all mine; HP might not want them anyway... feel free to post, OR email to rick.jones2 in hp.com but NOT BOTH... |
