* Fit 1 metre of rolled up surgical tubing to the brass static tube connector under the panel.
Watch the pressure instruments while slowly unrolling the tubing. The altimeter should start
to show an increase in altitude. The vertical speed indicator should start to show a positive
rate of climb and the airspeed indicator may show a small positive indication.
When the altimeter shows 2000 feet pinch off the tubing. There will be some initial decrease
in altitude and the vertical speed indicator will read zero. The altimeter should then hold the
indicated altitude for at least one minute. If altitude is lost then look for leaks.
Note: NEVER apply suction orally or mechanically to a static line - it can damage the
instruments.
