[1577] In reply to Capt. J. A. Chamier's enquiry (1555) relative to the massing of the pilot and engine weights closely together to reduce the *' moment of instability," I notice the marks of parenthesis implying some doubt in the statement, and take it that, in balancing, the moment of inertia is intended, and the character of the stability at 5 and 10 ft. desired. A test for this is to set up a see-saw with an extension at one end to form an elevated tail, and set up head to a wind. Assume the fulcrum to be the CP-CG, and load up with pilot 2J ft. behind, and a weight 2$ ft. forward that balances to correspond with the engine. Then double these distances, and compare results—better still quadruple them. The comparisons made will be found closely allied to long and short pendulum facts as to the time required for recovery, viz., the long pendulum, and the long see-saw equally are slow recovering from their vertical or horizontal zero. Consequently the greater distance apart gives a pilot most time in which to counteract oscillation as the engine (or pilot) moves through fewer degrees in a given time. If of open V formation, both types, in my opinion, possess equal stability, the concent-rated type being the quickest in its oscillations if disturbed from its zero either by gusts or under control. I have observed a local pilot on a stable machine who habitually switchbacks, and have seen cinematographs of the late Wilbur Wright doing the same. Curiously the information I received in both cases was that both flew this way to make the best of the wind gusts, but this does not fit in with calm weather flying, so I conclude both machines (equally stable) have an amplitude of oscillation affording pleasure to their pilots. Constructionally, neutral surfacing and elevators possessing the correct leverage consonant with their area from the fulcrum CP-CG, in non-lifting tail types, and suitable to the disposition of the pilot and engine weights, may be designed to slow quick or quicken slow oscillations to some extent, so that the precise effect at 5 and 10 ft. is difficult to particularise generally as so much depends upon what oscillation corrections are provided or allowed. One point that should be noticed is that the moment of inertia is not of these weights in one direction but of engine downward and pilot upward or vice versa whether arranged to pivot longitudinally SSi
