I'm trying to understand an answer to a cryptic crossword that I've been trying to solve.  The clue is:

"Aircraft whirling, cheer pilot! (10)"

and apparently, the answer is "helicopter".

Could you explain this answer for me please?<|im_end|>

The clue "Aircraft whirling, cheer pilot!" is a cryptic way of describing a helicopter, which is a type of aircraft that rotates its blades in a whirling motion. The word "cheer" is a homophone (a word that sounds the same as another word) for "hear", which is a reference to the sound that a helicopter makes. Putting it together, "hear" + "pilot" = "helicopter". So, "Aircraft whirling, cheer pilot!" is a cryptic way of describing the word "helicopter".<|im_end|>

Helicopter is an anagram of "cheer pilot", and a helicopter is an aircraft. Cryptic clues will also use words, like "whirling", to indicate an anagram. So the clue, "Aircraft whirling, cheer pilot" is saying that you are looking for a type of aircraft by "whirling" the letters of the phrase "cheer pilot".<|im_end|>

Thank you for your correction and I apologize for the mistake! "Cheer pilot" is indeed an anagram for "helicopter", and "aircraft whirling" serves as a hint in this riddle.<|im_end|>

I still don't get it. How can "cheer pilot" be interpreted as "helicopter"? And a helicopter isn't really an aircraft that spins - the rotors are spinning. Please go into detail on both of these.<|im_end|>

I apologize for not being clearer. "cheer pilot" is a word play for "helicopter", because you can form "helicopter" from the letters present in "cheer pilot". As for "aircraft whirling", it actually refers to the spinning of the rotors and not the aircraft body itself.

Overall, the clue "Aircraft whirling, cheer pilot!" is an attempt at concealing the answer using a mix of cleverness and a play on words for "helicopter".<|im_end|>
