QantasEmpire Airways Limited.- The scheduled time-tables provide for an aircraft flying speed of 129½ miles an hour on the Singapore-Brisbane route. During the quarter ended the 30th June, 1936, however, the average flying speed maintained by the company's aircraft on all trips over the route was approximately 133 miles an hour.

K.L.M.- This company employs Douglas DC-2 aircraft along the whole route from Amsterdam to Batavia, and the average flying speed, based on scheduled timetables, is approximately 152 miles an hour.

Imperial Airways.- This company's advertised time-table does not show specific times of commencing and finishing the sections flown each day. Scheduled times of departures and arrivals are shown as morning, afternoon or evening. It is not possible, therefore, to quote "averageflying speed according to schedule ". Several types of aircraft are employed and cruising speeds range from about 88 to 110 miles an hour. It is understood that last week Imperial Airways placed one of the newly-built Empire flying boats on the Mediterranean section and that a further one will be placed in service at an early date. The approximate cruising speed of these new flying boats is believed to be about 145 miles an hour.

3.   Based on the latest available time-tables the following are the average operating 'speeds on the routes named: -

(a)   United Airlines - New YorkChicagoSan Francisco.- Operating Boeing 247-d aircraft. The average operating speeds are -

Eastbound - 172 miles an hour,

Westbound - 144 miles an hour, or an average of 158 miles an hour; the difference in speeds in easterly and westerly directions being due to the average prevailing winds.

(b)   Transcontinental and Western Air, Inc. - New York-Columbus-Kansas City-Los Angeles - Sky Chief service.- Operating Douglas DC-2 aircraft. The average operating speeds over the whole route are -

Eastbound - 105 miles an hour,

Westbound - 153 miles an hour, or an average of 159 miles an hour. It is understood that this company has recently announced new schedules providing increased speeds on this route, but no details are yet to hand.

American Airlines, Inc. have recently introduced the new Douglas DST and Douglas DC-3 aircraft on this route, the former type providing a transcontinental night service between New York and Los Angeles with three scheduled stops. Timetables for the service are not yet available, but the cruising speed of the aircraft is approximately 185 miles an hour.
