An aircraft has indicated that he wants you to change course and follow him. You cannot comply because of an emergency on board. Which signal should you make?

A Make a round turn
B B
C C
D D
AI Explanation

The correct answer is D) D. The signal you should make in this situation is the "D" signal, which is the international signal for "I am unable to comply". This signal is used when a vessel or aircraft is requesting you to take an action that you cannot comply with, such as in the case of an emergency on board your vessel. The other answer choices are incorrect because: A) Making a round turn would not communicate your inability to comply with the request. B) "B" is not an international signal that has a defined meaning. C) "C" is also not an international signal that has a defined meaning.
