“UNRELIABLE SPEED INDICATION / ADR CHECK”
Conclusion
The UNRELIABLE SPEED and ADR CHECK PROC are now gathered in asingle paper procedure called:
Conditions added in the procedure for :
Applying the Memory Items
Level off for troubleshooting faulty ADR / Use the Back-Up Speed Scale
Situation Awareness and procedure understanding are improved by the FCTMand the e-briefing
