This Wishlist may suit you more:
The reason I made this Wishlist topic is because in real life, someone may not see that you turned your beacon lights on and/or they may not be facing the aircraft, and/or you may not see them. “Clear prop” is a safety item, and unfortunately, yelling it in your living room won’t help.
That being said, I’ve also voted for the above item, too. Once the engine is running, I hope that any AI ground personnel will be smart enough to back away.
