RATE
• In aeronautical units (kts, km/h), this key shows the rate of change of airspeed (Rate CAS).
• In pressure units (mbar, inHg etc.), this key shows the rate of change of pressure (Rate Qc)
display.
• In leak measure mode the display shows the current rate of change. In control mode this key
selects the fixed rate of change of airspeed (Rate CAS) of 300 kts/min or the equivalent rate
(Rt Qc) in pressure units/min.
• Select [UNITS], from the main menu, to change between aeronautical and pressure units.
• Use LEAK MEASURE/CONTROL to change between Control and Leak Measure mode.
