In an embodiment, an ice-prevention dam for a pitot tube includes a body and a head. The body includes a notch having a substantially planar back, and the head extends from the body and has a substantially planar side that is substantially parallel to the back of the notch. Such a dam can prevent ice accumulation in a pitot tube, and can facilitate proper positioning of the dam. For example, during manufacture of a pitot tube, an assembler inserts the dam into a hole in a side of a pitot-tube body having a front opening such that the head of the dam is located outside of the pitot-tube body and a body of the dam is located inside of the pitot-tube body. Next, the assembler positions the dam by causing the substantially planar side of the dam head to be substantially parallel with the front opening of the pitot-tube body.
