Three airplanes I could and still can always tell :
- Piaggio Avanti
- MU2
- DA42 with Thielert engines.
As far as music to your ears, it’s nothing like a big piston engine going at full bore.
Not a big fan of jet engines unless it’s an afterburner take off although some sound better then others with full A/B.
As a ramp worker always enjoyed the pushback and engine start of the last of Delta’s L-1011.
The spooling up followed by the clicking of the igniters then the WHOOSH when the burners lit and it truly came alive.
Modern jet engines seem to lack that.
