1.
In aeronautical units (kts, km/h), this key selects a rate of change of airspeed (Rate
CAS) display. The following rates are available in aeronautical units:
2.
In pressure units (mbar, inHg etc.), this key selects a rate of change of pressure (Rate
Qc, Rate Pt or Rate EPR) display. The actual display depends on the parameter
selected before pressing
