Thank you


I expect Pete Stickney will be giving you his patented thrust vs.
horsepower
lecture shortly, if he's not on vacation or otherwise occupied. If youre
in a
hurry, you could do a google search restricted to this group with
as the author and "Maximum Speed of Airliner at Low
Altitude" as the subject, and you'll get one of his recent posts which
discusses this subject in some detail.

The short version is that propeller thrust = horsepower @ 375 mph. HP is
greater than thrust below that speed, less above.
