      Take-off data from [Cassidy:2004:FE], page 156/149:

      "Take off runs and times aircraft with Pegasus XC engines at sea
      level in temperate climatic conditions were quoted as follows:"

        43 500       690    31.5        550    28

      "Lake Victoria was the highest port on the South African route
      at an altitude of 3 720 ft. Take-off times at this height could
      be as much as 100% longer than the standard sea level
      condition. At sea level in tropical conditions, the take-off
      runs were often extended by between 50% to 100% and the take-off
      times by 50% or more. Typical times at Bathurst, for example,
      were 92 and 107 seconds." ([Cassidy:2004:FE], page 156/149)

      "The normal trim angle for a standard displacement Empire 'boat
      hull at rest in the water, was 4 deg. 15min.- nose-up. Flying-boat
      hulls change their attitude as speed builds up during take-off.
      The tank tests at Rochester showed that as a standard displacement
      Empire 'boat began to move, the angle increased to 7 deg. at 15 knots,
      to 10 deg. at 25 knots, with a peak of 13 deg. at 30 knots, and then
      decreased to about 12 deg. until the 'boat left the water at about
      78 knots." ([Cassidy:2004:FE], page 28)

      "Arthur Gouge quoted a minimum 9 deg. positive angle from datum
      as the trim angle of an Empire 'boat as it was about to leave
      the water rather than the 12 deg. angle of the tank tests,
      putting the mainplanes at an angle of attack of 12 deg."
      ([Cassidy:2004:FE], page 29)

      "The variable pitch airscrews of the Empire 'boats - in FINE
      pitch for take-off - developed a thrust of 13 280 lb. (59 kN) at
      20 knots." ([Cassidy:2004:FE], page 28)
