Talking about talking. Recently was astounded by the number of read and do checklist items in the Metro 227. While the number of spoken checks depend on the operator, the following is a bit overboard? This from an Australian operator of Metro aircraft.
83 challenge and response up to point of starting engines.
24 challenge and response after start drills.
19 challenge and response between after start complete and airborne.
11 challenge and response after take off checks.
11 challenge and response climb to cruise checks.
31 challenge and response from top of descent to touch down.
10 challenge and response after landing checks.
Total 189 challenge and response with many more to come for shut down checks.
Compare that little lot to the Boeing 737 manufacturer's recommended checklist of 42 challenge and response items from before start to shut down. Do more checks mean a safer operation?
