On #14 I mentioned a Google reference to "Fuel Economist"
The Flight article (from 1975) was entitled "Precision Precedes Profits" ( which sounds a little over the top !). In the article it was stated that flying more economically increased flight times by 1 minute 23 seconds for each hour of flight for one fleet. (IE. not really noticeable in scheduling)
Yesterday Ryanair said that they were ordering their B737NG fleet to reduce their cruising speed to "save 15% of their fuel cost", thus increasing flight times by 2 minutes per hour.
Pprune has a wide readership. Congratulations !
Or was this just a coincidence ?
