Divergent Phugoid
While in the circuit I once had a wasp come out a C150 wing root airvent. Another time a student puked all over the instrument panel obscuring most of the instruments
. Because of those incidents I did not subsequently add to my prelanding checklist
Wing air vents -------- close
or
Puke Bag -------------- give to student
So why would I put something on the checklist that has NEVER in 5000 hrs, happened to me. I think you have to be carefull about invoking the " safety " word. Safety does not come from mindlessly following a printed list , it comes from fully understanding the relavance of each checklist item and always maintaining the correct priority of actions at any given time throughout the flight.
