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. However, such

accuracy checks must be limited only to aircraft that are not RVSM compliant. The 6150 is

NOT RVSM compliant. However, the relatively high accuracy (see specifications) of the

6150 makes it suitable for use to perform only leak-checks even on RVSM compliant

aircraft.

The 6150 has powerful built-in pumps for vacuum and pressure. Altitudes and Airspeeds

can be simulated on the Static and Pitot outputs by using the metering valves provide on

the unit. There is no maintenance required on the 6150, other than the annual calibration.

The top panel of the 6150 is shown in Figure 1. The different components on the top

panel, indicated by numbers in Figure 1, are explained below.

1. Static output port

This #4-AN port is normally connected to the Static port of the aircraft. As an option, this

port can also be fitted with a #6-AN fitting.

2. Pitot output port

This #4-AN port is normally connected to the Pitot port of the aircraft.

3. AC input connector

This 3-pin circular connector accepts AC input power for the unit. AC power between 90-

260 VAC and 47-440 Hz is suitable for the unit. Nominal power consumption is 70 VA.

4. AC Fuse

The AC input power is fused with a 1 amp slow-blow, 20 mm fuse.

5. ON /OFF switch

This is used to turn power to the unit, ON or OFF.

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. Not even finger-tight. Any tightening past the STOP may cause

permanent damage to the valve and it will constantly leak.

7. PRESSURE or AIRSPEED metering valve

This valve is used for increasing airspeed or pressure at the Pitot output. With the Cross-

bleed valve open, it can also be used to create pressure on the Static port for altitudes

below field elevation (like -1000 feet) .

CAUTION : This metering valve seals before it reaches its STOP. Do Not tighten at all

past this STOP. Not even finger-tight. Any tightening past the STOP may cause

permanent damage to the valve and it will constantly leak.

8. CROSS-BLEED valve

When this valve is open it equalizes pressure between the Pitot and Static outputs and

provides Zero airspeed.. When this valve is closed it isolates the Pitot and Static outputs

and allows the user to create a specific airspeed, either by opening the Vent valve or the

Pressure valve.

CAUTION : This metering valve seals before it reaches its STOP. Do Not tighten at all

past this STOP. Not even finger-tight. Any tightening past the STOP may cause

permanent damage to the valve and it will constantly leak.

9. VACUUM or ALTITUDE valve

Opening this valve increases altitude or vacuum on the Static output. If the Cross-bleed

valve is closed while altitude (vacuum) is increased on the Static output, this will cause

airspeed to increase automatically on the Pitot output, even if the Vent valve is open, since

the difference between Pitot pressure and Static pressure increases. If the Cross-bleed

valve is open and the Vent valve and Pressure valve are closed, opening the Vacuum

valve will increase altitude on the Static output but maintain close to Zero airspeed on the

Pitot output.

CAUTION : This metering valve seals before it reaches its STOP. Do Not tighten at all

past this STOP. Not even finger-tight. Any tightening past the STOP may cause

permanent damage to the valve and it will constantly leak.

10. Keypad

There are four keys:

The LEAK CHECK key is used to enter the Leak-test mode, and also for some other

functions.

The FUNCTIONS key is used to scroll through several functions (detailed later). It is also

used for some other actions.

The GO key is used to execute certain commands or options.

The CANCEL key is used to cancel certain commands or functions. This key is also used

to return to the Main Screen on the display.

11. Display

All indicators and readings are shown on this 40-character by 4-line LCD display. The

display is backlit for easy viewing in all lighting conditions. The various screens shown on

the display are explained in detailed in Section 2.

12. LEAK-TEST SHUTOFF solenoid-valves

There are two valves, one on the Static output and one on the Pitot output. During the

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.
