I can pretty much guarantee that somewhere above the Earth there are 2 pilots discussing cicadas, Biden (for sure), global warming, Covid, and pretty much every other subject you can imagine. After the initial pre-screening process:
How long you been here?
Where were you before?
How was training? Who’d you have?
Where do you live? (How’s that commute?)
How’s your schedule this month?
There a new bid coming out, you staying here?
Did you hear what happened with Capt Smith over the weekend?
Do you believe the airline is planning…? Mgmt doesn’t have a clue and the Union isn’t doing anything about it!
Inevitably the conversation will turn to just about anything and everything. We’re told not to talk about religion, politics and sex but people will. Most are fairly innocuous but always be wary of the preface “I’m super laid back”, they’re not. If they say “well I didn’t vote for… BUT, “I’m not a Liberal (or Conservative) BUT…”, I’m not sayin’…BUT…” they’re lying and be ready for a LENGTHY conversation on the subject.
Now that I’ve cleared that up I personally have never had or heard of any cicadas caused delays. However, when we first got our A330s (over a decade ago) we did have a mud wasp issue. A crew started their takeoff roll. Now during the roll the pilot monitoring will call out certain target speeds and the flying pilot will respond “check”. When the the PM called X speed the PF saw no speed indicated. This is obviously a red flag and the takeoff was aborted. It was discovered there’s a certain variety of mud wasp that can build a nest fairly quickly (within a few hours) and the A330 pitot tube is pretty much the exact diameter and height off the ground that this particular mud wasp finds absolutely irresistible to build their nest. The solution was rather than remove the pitot covers early in the day, they’re left on until the final walk around. I also have a story from when I was at the Regionals and a Capt (who had read a story that morning about a West Nile outbreak in Montrose CO, we were departing from MTJ) going nuts on T/O trying to kill a very large mosquito in the cockpit. So yes insects can be a problem.
