so the sensitivity of the pedals increases with the square of the airspeed. Thesecharacteristics are illustrated in figure 8
which compares the A300-600 and A300B2/B4rudder pedal sensitivities as a function of airspeed and shows that the A300-600 is twiceas responsive to a pedal displacement at 250 knots KCAS than at 165 KCAS.Figure 8. A300-600 and A300B2/B4 Rudder Pedal Sensitivities1.6.2.3 A300-600 Rudder Control System Design ComparedWith Other AirplanesThe Safety Board compared the rudder control system design characteristics of theA300-600 with the A300B2/B4
other Airbus airplanes
and Boeing- and McDonnellDouglas-designed airplanes
as shown in table 4. Also
the Board used four metrics toquantify aspects of pedal sensitivity at 250 knots for the same airplane models
as shownin table 5. These four metrics were (1) the ratio of maximum force to breakout force
(2)the degrees of rudder commanded per pound of force above the breakout force
(3) the
