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?
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.
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.
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.
