PRECAUTIONS AND SAFETY MEASURES
CAUTION: Instruments can easily be damaged if test is performed improperly. Manipulate test equipment
slowly and carefully. Monitor indicators and make sure that indication is always within normal indication
range!
PROCEDURES
Pitot System Test
1
Pull-out plunger of test equipment for the pitot nozzle (long silicone tube) to read 2 ml.
2
Attach test equipment to pitot nozzle.
3
Slowly depress plunger to read 1 ml. Airspeed indication must increase significantly.
NOTE: The actual value will depend on the length and cross-section of the pipework
installed.
4
Leave set-up unchanged and check decay over 10 seconds. Decay should be less than 10% per 10
seconds.
5
Gently ease tube off the pitot nozzle. Airspeed indicator(s) must return to zero.
6
If any of the preceding tests has failed, have system inspected and repaired.
Static System Test (if installed)
7
Block one static port with a strip of tape.
NOTE: Do not use transparent tape as this may be overlooked and forgotten. It is
recommended to use red insulating tape with a relatively large extending end.
8
Press in plunger of test equipment for the static port (short silicone adapter) completely.
9
Press and hold test equipment to the open static port tight to the hole.
10 Pull plunger slowly about 3 ml.
11 Indicated altitude and airspeed indication must increase.
12 If installed, VSI indication must increase momentarily and will slowly fade to zero.
13 Leave set-up unchanged and check decay over 10 seconds. There shall be no noticeable decay (except
VSI).
14 Remove silicone adapter from static port. Altitude must return to initial indication.
15 If any of the preceding tests has failed, have system inspected and repaired.
