Force and moment measurements on a conical body and a rectangular wing, seperately and in combination, at Mach number 1.94

A mechanical design study for a six motion, numerically controlled machine for finish grinding large wind tunnel models

This Note describes the layout of a proposed machine for finish grinding wind tunnel models up to 5 feet by 3 feet plan area. Although the design has not been carried beyond the arrangement stage fairly detailed proposals are submitted for the more difficult mechanical features.

Results of the 1965 flight-deck data collection on height keeping over the North Atlantic

In response to a recommendation of the special NATRAN meeting of I.C.A.O. at Montreal in February 1965, the International Air Transport Association has collected flight-deck records of altimeter readings on 11000 trans-Atlantic jet flights in the period April to August 1965. These data have been processed in the Mathematics Department of the...

Survey of the errors of pressure measuring instruments in relation to air traffic separation standards

A simple account is given of the accuracy of height and speed measurements in current types of aircraft. Estimates of the errors likely to be encountered at jet cruising levels are given together with an outline of the conditions which should be met before any reduction in separation standards can be justified.

Specifying the calibration of static pressure systems for the safe use of 1000ft vertical separation standard in North Atlantic jet traffic
