13.4.3 Pitot Tube Installation

This entry is part 1 of 67 in the series 13 - Electrical / Instruments

The pitot tube is what measures the airflow so that we know how fast the airplane is moving through the air. This sucker was pricey too. Malcolm had some steel stock with the same cross-section as the pitot tube. So I cut a length of it and drilled four mounting holes in it.

The manual calls out the location of the pitot tube as 6.75 inches below the canard and 18 inches forward of the door.

+ marks the spot.


And the hole is cut out.

The sleeve and pitot tube dry fitted.

Then the structural adhesive is mixed and the sleeve is permanently installed. The alignment is important to insure a correct airspeed indication.

Forward alignment is accomplished using a framing square clamped to the canard bulkhead and visually referencing the pitot tube to the framing square.

And we used a digital level to verify that it’s… level. The tripod is used to hold the position while the epoxy sets.
