What are the odds of spearing a bee with pitot
There have been several discussions about insects clogging vents and airspeed plumbing but what are the odds of hitting a critter so as to plug the pitot in flight?
This afternoon on takeoff at rotation speed I had an airspeed fluctuation. Compared to the other indicators it didn't agree. Soon Followed by FADEC warnings along with a list of other system malfunctions.
Just under max landing weight, we returned to find this bumble bee tail first in the pitot tube with it's head too large to enter.
I have to say, never saw that before.

What are the odds of hitting a bee (or some other bug) on takeoff from Oshkosh? Thankfully, it worked its way back so as not to completely block things after a few minutes, but it happened to me five years ago. Look at your windscreen are leading edges. You hit a LOT of bugs!

Count me in as having a pitot hit by a bug just after rotation leaving Fredricksburg Texas. Lost all airspeed, the bug was so big I saw it out of the corner of my eye just before the airspeed went dead.

My former 182 partner lost airspeed data just after rotation at Johnson Creek ID. Bug in the pitot. He said he was glad it wasn't IMC.

Obviously the pitot tube was mounted .5 inches to high on the fuselage. haha!
I like the drop down door on your 8 too!

Come on, what are the chances.
I mean really.

Not to worry...bugs don't fly in IMC, do they?
