RVSM Static Port Height Inspection
The Gauging Assembly p/n SPF-4 (A1M-BCH-GE) is available from Hawker Beechcraft. Any alternate
tool authorized in the Super King Air 300 or B300 Maintenance Manual for RVSM static port
measurements may be substituted for this tool. Initialize the tool as follows:
1.
Make sure the dial indicator reads negative when the plunger is pressed and positive when the
plunger is free.
2.
Place the gauging assembly on a flat surface (gauge block or equivalent.)
3.
Ensure the smaller needle is at approximately (.1).
4.
Rotate the dial indicator to set the large needle at (0) as shown in Figure 7-12.

The static port measurements are obtained at four locations on each static port as shown in Figure 7-14.
These measurements are used to find an AVERAGE and ANGLE for each of the four static ports. The
AVERAGE is calculated by adding the four measurements and dividing the total by 4. The ANGLE is
calculated by subtracting the minimum measurement from the maximum measurement. The calculated
AVERAGE and ANGLE for each static port must fall within the ranges shown in Figure 7-15.
Perform the static port measurement as follows:
1.
Wipe the surface of static ports clean with isopropyl alcohol.
2.
Place the gauging assembly onto the static port surface as shown in Figure 7-13.
