This subject has stirred debate for many years. How many instructors actually carry out engine out landing practice with one actually feathered? Should this be left to practice at an appropriate altitude rather than in the circuit where an error in judgement can create a greater risk factor.
The age and condition of our aircraft should also be taken into consideration as how many will actually be capable of a missed approach at Maximum Take-off Weight? A colleague put two new props on his aircraft and gained eight knots. What sought of climb out would this aircraft had at Max weight on one?
Students should be made aware of these problems because the decision to go around may not be an option in some aircraft. Even an EFATO on some aircraft should possibly be handled the same way as a single engine aircraft.
