Plumbing and Static Sources

Aft fuselage statics work well but can be more susceptible to clogging when dumping water ballast in certain gliders with lower-surface-of-wing outlets (e.g., my old LS 3, in which owners installed a switch to pump pitot pressure through the lines to keep them clear). Probes are vulnerable to ground handling damage and in-flight spearing of geese. Your call as to which is more likely.
