1811 SERIES
PITOT-STATIC TEST SET
INFORMATIONAL LETTER
The Barfield 1811 series Pitot-Static Testers are not advertised for use to comply with
FAR 91.411. The Test Sets do fully meet the requirements of DOT Advisory Circular 43-203B
for performing Altimeter and Static System Tests and Inspections. However, the personnel
requirements and some of the technical aspects of actual testing put a sizeable burden on the
person or persons performing the test.
Barfield advertises its 1811 series Test Sets as general-purpose trouble-shooting testers. With
respect to compliance with FAR 91.411, we feel that the customer should first be aware of all
requirements for performing test tests in the field. With this in mind, Barfield stands ready to
offer advice and assistance to its customers for accomplishing the required tests.
In conclusion, the Barfield 1811 Series Pitot-Static Testers meet the requirements for
compliance with FAR 91.411, but it is important that the customer be sure that the use of the
test set will be in compliance with the regulations.
Please note that a Barfield Altimeter and Static Test Procedure (Document number 60-101-
00150) is available to use in compliance with FAR 91.411.

B. Each new or re-certified unit is delivered with a Certificate that shows the date when the
unit was tested by the manufacturer, its serial number, and when the next certification is
due. This certificate confirms that the unit performed according to its design
specifications.
C. The one year limited warranty for this unit (Figure 2).
3. RECERTIFICATION
The Test Sets P/N 101-00184 and P/N 101-00185 have a 6-month recertification period
when analog instruments are installed. However, when digital instruments are installed the
recertification period is typically one year. For complete specifications on digital
instruments, refer to documents 61-101-02184 and 61-101-02194.
It is strongly recommended that the manufacturer, Barfield Inc., service the Test Set. This
will ensure that all applicable engineering change orders are incorporated during the
required maintenance or recertification procedure. Additionally, at this time only Barfield
technicians are qualified to service the digital instruments.
Note: It is important that the customer ensures the Test Set is in compliance with the
Recertification requirement.
Note: If the Test Set is to be used in compliance with F.A.R. 91.170 and Part 43, Appendix
E, "Altimeter System Tests and Inspections," refer to FAA Advisory Circular AC43-6B
(or subsequent) for approved inspection intervals and procedures.

CHAPTER 1: GENERAL INFORMATION
1. TEST SETS DESCRIPTION
The BARFIELD INC. 1811HA /GA (Figure 3) is a Pitot-Static Test Set, intended to test
aircraft Pitot and Static Systems for leaks and to test the operation and calibration of
airspeed, altimeter, rate of climb, and other vacuum or low pressure units. The Test Set is a
portable unit enclosed in a fiberglass carrying case.
Note: The pitot and static port adapters fit many aircraft universally but, in some cases, these
adapters are not recommended or are inadequate. Barfield Inc. distributes high quality
custom-made pitot and static adapters for use on all general aviation, airline, helicopter
and military aircraft. Visit our web site at www.barfieldinc.com or contact the Barfield
GSTE – Sales Department at [phone] for more information.
1811HA Test Set (P/N 101-00184-SERIES) 1811GA Test Set (P/N 101-00185-SERIES)
Figure 3 Overview of the Test Sets
The 1811HA
/ GA Test Set is equipped with reference master instruments with
appropriate correction cards. (See Appendixes). Panel mounted hand pumps are
equipped with reservoir tanks to supply pressure and vacuum. Metering valves are
provided for control of all pneumatic functions. Ports are provided for external
connections. The 1811HA model also contains an integral electric pressure / vacuum
pump.

2. PHYSICAL DESCRIPTION
A. Carrying Case
The Tester comes with a fiberglass carrying case that contains upper and lower
sections: The lower section supports the panel assembly. The upper section has sliding
pin hinges for easy removal and is fitted with a shelf suitable for storing the manual,
hoses and the power cable.
B. Part Number Variations
There are two basic model numbers: 1811GA which has manually operated pumps, and
the 1811HA, which has all the features of the 1811GA in addition to an internal electrical
pump to supply vacuum or pressure. The three-character code at the end of the part
number identifies the various indicator combinations which are available. The three-
character code at the end of 101-00184-635, for example, specifies the Airspeed
indicator range, Vertical Speed indicator range, and the Altimeter range. The “6”
indicates an Airspeed indicator with a 20-250 knot range. The “3” indicates a Vertical
Speed indicator with a 3000 ft / min range. The “5” indicates an altimeter with a 3
pointer, 35,000 ft, in-Hg / mb Baro Scale. Refer to Table 1 for available indicator
combinations.
