Here is a good site with more in-depth information on the pitot static system:
I also agree that MX
personnel should start using bright orange or red tape, that is easier to see day and night. If you are going a night pre-flight it's next to impossible to see clear tape (what most folks use around here) over the static port. I figure that painters tape, should be water proof enough, but should also be able to come off without leaving a residue.
I should also mention that some older general aviation planes uses a flap over the pitot tube that automatically comes up as the aircraft accelerates, it's rather interesting, but they do sometimes bend either putting the flap in a permanent up position, or in most cases (well the ones that are noticed by pilots at least) in a permanent down position.
But since it's the pitot tube the pilot should notice that airspeed doesn't, as many of us say on our during take off flow, "Come alive," and simply abort the take off, and see what's wrong.
At worst, you screw up and die.
