Hughes, N.H. (author)This Report describes analogue simulation studies and full scale flight experiments into the affects on automatic landing lateral performance of interference to the I.L.S. localizer caused by reflection from an aircraft taking-off. The results show that if safety is not to be affected, interference must cease before the landing aircraft has...report 1968

Hughes, N.H. (author), Lazenby, G.P. (author)A flight experiment is described which was designed to confirm the results of an analogue computer study of the effect of initial conditions at the entry to the flare-out on the touchdown performance of au automatic landing system. The flight results generally justify the conclusions from the computer study but differences appear at high initial...report 1965

Hughes, T.L. (author)Though several instruments are available for the in-flight measurement of atmospheric ice concentration, they all have some limitations. This Note describes some early development work on an ice concentration meter employing a lithium chloride cell which appears potentially capable of overcoming these limitations. The lithium chloride ice meter...report 1964

Hughes, N.H. (author)A flight experiment is described to determine the height loss during a manual blind overshoot following a positive warning to the pilot during the late stages of an automatic approach. The loss of height was found to depend on the rate of descent at the overshoot height and the variability of pilot performance but no other factors were found to...report 1964

Hughes, J.M. (author), King-Hele, D.G. (author)A Table is given of all known artificial earth satellites, including fragments, launched before 1st January, 1962, with lifetimes, weights, dimensions and details of the orbits at specified dates. The methods used in compiling the Table and the difficulties encountered are briefly described.report 1962

Hughes, J.M. (author), Cook, G.E. (author)The formation of belts of Needle satellites, which have been proposed for long-range radio communication, is discussed. The perturbations of these belts are investigated by studying the combined effects of solar radiation pressure and the earth's gravitational potential on satellites of large area-to-mass ratio.report 1961
