TABLE 6.10.3.3.1.T10:
As long as the alert occurred at least once during the flight, its associated counter is incremented only once per flight no
matter how many times that event occurred during the flight.
The system is capable of storing a minimum of 100 alert history records. Once the limit on the number of alert history
records is reached, records will be over-written starting with the oldest records.
6.10.3.3.2 Alert History Records
Each time any of the events listed in table 6.10.3.3.2.T10 occurs, an alert history record will be created in non-volatile
memory. Each alert record contains a history of EGPWS signals from 20 seconds prior to the event to 10 seconds after the
event. Refer to section 6.10.14.4 for display of warning history.
