(calls are 80kts/60kts/40kts).
Are all these calls mandated by the aircraft manufacturer? If not what is the point of the calls and what action does the PF take if the calls are not made. Seems like an overkill to me although I have never operated the aircraft. Boeing have a 60 knot call as reminder for slowly coming out of reverse but it is not clear whether this is an indicated airspeed or ground speed call.
