    CHAPTER 3. OPERATION 1. THEORY OF OPERATION The 1811HA / GA Pitot-Static Test Sets (T/S) test the aircraft Pitot and Static Systems for leaks. The Tester is also used to operate and calibrate airspeed, altimeter, rate of climb, engine pressure ratio, manifold pressure indicators, and other vacuum or low pressure units. Panel mounted hand pumps are equipped with reservoir tanks to supply pressure and vacuum.

  • Page 26: Power Supply Circuits

    C. Power Supply Circuits The 1811HA can be powered from 100 - 240VAC / 50 - 60 Hz. The internal power supply automatically detects input voltage applied of 100 - 240VAC. 2. 1811GA PNEUMATIC SCHEMATIC DIAGRAM The 1811GA internal pneumatic connections are shown in Figure 6.

  • Page 28: Preliminary General

    4. PRELIMINARY A. General The 1811HA / GA consists of a hand-operated vacuum pump and a hand-operated pressure pump. The pressure pump is single action developing pressure on the down stroke only while the vacuum pump is double action developing vacuum on both the up and down stroke.

  • Page 29: Pretests

    The VACUUM GAUGE (#9) will show the available vacuum (minimum 25 inHg) for the static vacuum source. After completing the test, return the internal electric PUMP SWITCH (#24) to OFF. 5. PRETESTS Note: To avoid incorrect results or damage to the aircraft or Test Set (T/S) instruments, the manufacturer recommends that the user pay particular attention to the following preliminary procedures.

  • Page 30: Applying Leak Correction

    C. Applying Leak Correction If the leak rate does not exceed 2 knots or 100 feet in 1 minute, determine the actual aircraft system leak rate by adding the observed rate obtained from a previous aircraft leak test to the recorded rate. D.

  • Page 31: Static System Test

    Note: The user may compare the aircraft airspeed with the T/S airspeed for calibration by applying T/S calibration card corrections when applicable. Close PITOT CONTROL (#19) fully CW. After the instrument indications stabilize, monitor the airspeed (#2) for one minute. The airspeed (value shown on the indicator) must not decrease by a value greater than 2 kts plus the leak rate (determined previously in the Pitot Pretest) of the Test Set.

  • Page 32: Static Leak Test For Non-Pressurized Aircraft

    B. Static Leak Test (for non-pressurized aircraft only) Note: When performing the Static Leak Test or if the aircraft airspeed indicator has a range of 150 knots (175 MPH) or less, do not exceed 1,000 ft increase above field level ambient. (During the test, both the aircraft and the T/S airspeed indicators increase as the altitude increases.) Caution:...

  • Page 33: Negative Altitude Tests

    Close the STATIC VENT (#10) fully (CW). Caution: If one of the following steps fails, close the STATIC CONTROL (#7) fully (CW). Gently, open the PITOT VENT (#17) to return system to ambient before disconnecting the T/S. Caution: If the T/S is used outside of the aircraft, monitor the VERTICAL SPEED INDICATOR (VSI) so that the aircraft VSI range is not exceeded.

  • Page 34: Vertical Speed Indicator (Vsi) Operation

    Note: If the airspeed pointer indication increases, the leak is in the pitot system. If the pointer decreases, the leak is in the static system. (3) After the test completes, gradually open CROSSBLEED CONTROL (#8) CCW fully. (4) Return system to ambient, by gradually opening the PITOT VENT (#17). Take care not to exceed vertical speed indicator range.

  • Page 35: Combined Pitot / Static Test

    When the vertical speed reference is no longer needed, close the VERTICAL SPEED (#3) control fully (CW). Note: Isolating the VSI at a pressure other than ambient, causes pressure to be “trapped”. As a result in later tests the T/S VSI (#4) could show descent (when paired with the Static System) even though the altitude is actually increasing.

  • Page 36: Above Field Elevation Tests

    If an airspeed test point is accidentally, exceeded do the following: Gently open the CROSSBLEED (#8) valve until the airspeed is 10 knots below the desired test value. (Some altitude change occurs.) Gently open the STATIC CONTROL (#7) valve to restore the altitude (#5) to a correct test point.

  • Page 37: Returning The Pitot / Static Test Set To Ambient

    Open STATIC CONTROL (#7) to raise the altitude to the next test point. (Use the CROSSBLEED CONTROL (#8) to maintain airspeed below the test point.) Once reaching the desired altitude, close both controls. (10) Repeat steps (3) through (9) until completing all airspeed tests at each desired altitude.

  • Page 38: Machmeter Test

    9. MACHMETER TEST A. Test Procedure Using the methods described in 8. COMBINED PITOT (AIRSPEED) STATIC (ALTITUDE) TEST, set an altitude (in feet) listed in the following table. Set the corresponding airspeed (in knots). Verify t`hat the MACH value obtained is the same as listed in the table for the settings.

    11. MANIFOLD PRESSURE GAUGE TEST A. Test Procedure Plug or cap PITOT PORT (#1). Connect STATIC PORT (#6) to manifold gauge to be tested. Close all T/S valves (#3, #7, #8, #10, #17, #19). Open the CROSSBLEED CONTROL (#8) fully and maintain it open. Verify that the ALTIMETER (#5) is set at 29.92 inHg (1013.3 mb).

  • Page 41: Low Pressure Tests

    12. LOW PRESSURE TESTS Note: The following test uses 0-12 PSI, 0-25 in-Hg or 1-340 in-H 0 ranges and is limited by T/S airspeed range. Refer to Table 6 for equivalent airspeed readings. A. Test Procedure (1) Connect PITOT PORT (#1) to pressure unit to be tested. (2) Close all T/S valves (#3, #7, #8, #10, #17, #19) CW.

  • Page 42: Vacuum Tests

    (4) Open PITOT CONTROL (#19) to establish desired reading on AIRSPEED (#2) for equivalent pressure as listed in Table 6. (5) Gradually open PITOT VENT (#17) CCW to lower airspeed reading or to return system to ambient. 13. VACUUM TESTS Note: The following test uses 0-12 PSI, 0-25 inHg or 1-340 inH 0 ranges and is limited by T/S airspeed and altimeter ranges.

Valve Leak Test Caution: Before performing the Valve Leak test, inspect for system or instrument leakage. (Refer to the appropriate Aircraft Maintenance Manual for information and proper procedure.) Note: Read sections “A”...

  • Page 44: Vacuum Vent Test

    Fully close the "VACUUM VENT" and monitor both AIRSPEED INDICATOR and ALTIMETER: Note: If the ALTIMETER moves down scale, the leak is located at the "CROSSBLEED" valve. If the ALTIMETER does not move but the AIRSPEED continues to decrease, the leak is located at the "PRESSURE VENT"...

  • Page 45: Resetting Needle Valve Positive Stop

    Note: An increase of altitude of more then 100 ft. means the leak is located at the "VACUUM" valve. Repair leak before continuing. 2. RESETTING NEEDLE VALVE POSITIVE STOP Note: Before performing Valve Leak Test or Resetting the Needle Valve Positive Stop, inspect the entire system for leaks at locations other than valve seats, i.e., connections, general plumbing and instruments.

    CHAPTER 5: INSPECTION RECOMMENDATIONS The manufacturer recommends that inspection be performed in the periods shown in Table 7. Table 7 Required Periodic Inspections / Recertification Intervals TIME PERIOD INSPECTION REQUIRED With Each Use Leak Test. Refer to “Pretest” Section on pages 17 and 18. For analog instrument configuration(s), refer to Analog Instrument 6 Months Specifications included in the Appendix of this manual.

  • Page 48: Chapter 6: Shipping

    CHAPTER 6: SHIPPING Use standard delicate electronic equipment packaging procedure when packing the Test Set for reshipment. To prevent damage from extreme atmospheric changes to the Test Set instruments, it is recommended that the STATIC VENT, CROSSBLEED CONTROL, AND PITOT VENT VALVES be in open position.

  • Page 49: Chapter 7: Storage

    CHAPTER 7: STORAGE A. Place a four ounce bag of desiccant inside the container B. Close and latch the cover. C. Store in a cool dry place. Note: Should the Test Set become exposed to moisture or very high humidity, dry as soon as possible and temporarily store in dehumidified area.
