Marker's Feedback

2018/JUL ? Answers lacked depth and in part c) a sketch would have shown exactly what was needed, but all but one answer tried to explain a graphical solution with text; this is poor technique

2022/JUL ? Part(a) produced some complex answers and a number of candidates drifted off into areas not concerned with starting air. A simple way of tackling this part of the question would have been in tabular form and that would have avoided candidates repeating items and allowed them to stay on the topic as asked.

Part(b) confused many candidates. It clearly asks for Three causes of an engine failing to fire on fuel but many candidates ignored the fuel bit and returned to an engine starting air system; clearly they did not read the question accurately.

Part (c). Some answers were very good but many were poor, indicating that candidates did not know how to transfer engine control even though all ships on which they had sailed must have had such an arrangement. Probably indicative of lack of awareness during qualifying sea time.
