  • Page 7: Introduction

    SECTION 1 INTRODUCTION The 6150 Digital Air Data and Leak Tester is a high accuracy Pitot Static Tester which can be used for performing leak checks on the Pitot and Static systems of all aircraft. It can also be used to perform accuracy checks on altimeters, airspeed indicators, air data computers and other air data related equipment on-board aircraft.
  • Page 9 6. VENT metering valve This valve is used to vent-to-ambient, pressure or vacuum from the Pitot output. With the Cross-bleed valve open, the Vent valve can also vent-to-ambient, pressure or vacuum from the Static system. CAUTION : This metering valve seals before it reaches its STOP. Do Not tighten at all past this STOP.
  • Page 10 Leak-test mode, both of these solenoid-valves are automatically closed to isolate the aircraft from the metering valves of the 6150. The 6150 can still monitor the altitude and airspeed on the Static and Pitot ports. However, once the solenoid-valves are closed, none of the metering valves will have any effect on the pressure (or vacuum) on the Static or Pitot outputs.

  • Page 11: Functional Details

    This section explains all the different screens and functions of the 6150. 2.1 Power On. When power is turned ON to the 6150, the display shows the sign-on screen for 3 seconds. The pumps remain OFF. After the sign-on screen, the display shows the Limits and Leak-times screen.
  • Page 12 1000 feet higher than the maximum altitude that will normally be generated with the 6150 for the user’s typical aircraft. For example, if the user will normally perform tests up to 30,000 ft. then the limit should be set at 31,000 ft..

    decrement in steps of 1 minute. The minimum value for leak-time 1 is 1 minute and the maximum is 18 minutes. When GO is pressed, the displayed value is accepted and the screen changes as shown below: Leak-time 1= 3 min.
  • Page 14 In this screen, (the values displayed on your screen will likely be different), 425 feet is the altitude being measured at the Static output of the 6150 and 6.5 knots is the airspeed being measured at the Pitot output. There is no change of altitude so the VSI is indicated as 0 ft/min.
  • Page 15 constantly make changes to the Vacuum valve. Slowly close the Vacuum valve as you approach the desired altitude. Decrease altitude: Close the Vacuum valve completely, then slowly open the Vent valve while watching the VSI. This will allow you to achieve altitudes all the way down to Ground.
  • Page 16 -30 knots. This relief-valve is active even when the 6150 is powered-off. There are two conditions during the operation of the 6150 when the internal relief-valve will NOT protect against negative airspeed.
  • Page 17 b. During Calibration Mode, the Leak Test Shutoff solenoids are closed. This prevents the relief-valve from providing the negative airspeed protection. However, this protection is normally not required during Calibration Mode. 2.3.7 Warnings While in the Main Screen, several warning messages are displayed to alert the user to existing or potential error conditions.

  • Page 18: Leak Check Mode

    Pitot and Static outputs from the pumps and the metering valves. In Leak Check mode the aircraft is not protected against negative airspeed. If a negative airspeed condition exists, the 6150 will automatically trip out of Leak Check mode to prevent excessive negative airspeed. See section 2.3.6 above.
  • Page 19 The start of the second, third and fourth lines show “1m:”, “2m:” and “3m:” which indicates that the leak times have been programmed for 1, 2 and 3 minutes. For changing leak-time values please see Section 2.2. At the end of 1 minute of elapsed time, the display appears as below: 4995 feet 0 ft/min.

  • Page 20: Functions

    Main Screen. Please see Section 2.3.7 above. There is one exception. If airspeed goes more negative than -20 knots while in the Leak Check mode, the 6150 will automatically trip out of Leak Check mode and return to the Main Screen. The Leak Test Shutoff solenoids will be opened to allow the internal relief-valve to protect the aircraft against excessive negative airspeed.

  • Page 24: Typical Use

    SECTION 3 TYPICAL USE This section outlines the typical method of using the 6150. 3.1 Setup 1. Turn ON the 6150. 2. Check the limits and leak times to see if they are acceptable. Change them if required using the steps outlined in Section 2.2. Once these values are acceptable, press GO. You are now in the Main Screen.

    7. Slowly open the Vent valve while watching the VSI. Altitude will reduce. Once altitude is close to Ground level, open the Vent valve completely to ensure that the system is completely vented. 8. Turn OFF the 6150. 9. Disconnect from the aircraft. 10. Close all valves.

    +15 and -15 knots. 6. If an altimeter accuracy check needs to be performed, skip to Section 3.5 7. Turn OFF the 6150. 8. Disconnect from the aircraft. 9. Close all valves.
  • Page 27 8. Continue to open the Vent valve (while watching VSI) until the system is completely vented. 9. Turn OFF the 6150. 10. Disconnect from the aircraft 11. Close all valves.

  • Page 28: Calibration

    CALIBRATION Equipment The calibration procedure for the 6150 requires the following equipment: 1. Pressure controller (Standard) with an accuracy of at least 0.004 inHg between 1 and 60 inHg absolute. The controller must be able to achieve pressures between 1.0 inHg (abs) and 60 inHg (abs).
  • Page 29 3. Using the Standard, generate exactly 1.000 inHg on both outputs. Allow the pressure to be stable for 1 minute to eliminate any temperature effects. 4. Note the actual readings on the 6150. These will be noted as the “As Found” Vacuum values in the calibration report. (Figure 4.1) 5.
  • Page 30 Allow the pressure to be stable for 1 minute to eliminate any temperature effects. 2. Note the actual Static value on the 6150. This will be noted as the “As Found” full- scale Static value in the calibration report (figure 4.1) 3.
  • Page 31 This error indicates that either the Standard did not actually generate 60.000 inHg when GO was pressed in step 4 above or there is large difference in accuracy between the Standard and the 6150. Unless this discrepancy can be resolved, calibration cannot proceed further.

  • Page 32: Calibration Report

    1. Using the Standard, generate the following pressures on the Static output of the 6150 in units of inHg : 1.000, 3.200, 6.400, 9.600, 12.800, 16.000, 19.200, 22.400, 25.600, 28.800 and 32.000. Note the Static readings on the 6150 at each pressure.
