After the installation of the different vortex generators, the wind tunnel velocity was calibrated using the pitot static tube mentioned above.
e] is the freestream static pressure at the nozzle center measured using a pitot static tube, and [P.
At 4 points of the route once expansion joints are installed, the one-time compensators can only be biased if the required static tube
biasing circuit is completed.
That means--to simple, regular maintenance--you've added complicated pitot static tube
checks and HADS leak checks.
Pay attention to the pilot static tubes
when covering the nose and windshield as you try to hook the main rotor pylon track opening.
