We're saying the same thing, Al. The Electra on direct routings matched jet block speeds on V routings. Free flight then, now and in the future breaks down as the traffic flow approaches the terminal area. LAHSO is breaking down as small jets requiring full rwy length replace turboprops. RNP, RVSM and similar may add to the toolbox. - RWM Allan9 wrote: > > RWM, > Perhaps you are aware of something that I'm not.
