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.
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 processes, which are to be done following BarfieldÂapproved procedures. 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.

SECTION 1: DESCRIPTION
1. GENERAL DESCRIPTION
The Barfield 1811D Pitot Static Test Set (Fig. 3), housed in a plastic carrying case, is a
portable, self-contained field tester designed to test aircraft pitot and static systems for leaks
as well as the operation and calibration of airspeed, altimeter, 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.
Metering valves provide control of all pneumatic functions. External pressure ports supply the
necessary pressure and vacuum needed for on-board testing. The 1811D has a 50 to 650 knot
sensitive airspeed and is available with a 35, 000 or 50,000 ft altimeter.
The tester consists of a hand-operated vacuum pump, a hand-operated pressure pump vacuum
and pressure gauges, 5 control valves, an altimeter and an airspeed indicator. The package
accessories include two 25-foot hoses, a pitot mast adapter, and a static port adapter kit which
enable the user to connect the aircraft pitot and static lines.
Different alternatives are available for the altimeter and airspeed indicators that are installed
in the tester, so the three-digit code that follows the basic part number of the 101-00164,
identifies which combination of them is provided with a particular tester. The first digit
indicates the airspeed range; the last digit in the code identifies the altimeter range (the
middle digit is always zero). Possible

knot airspeed indicator and a 35,000 feet altimeter. (The 1811D is also available with the
Barfield DAS650 digital airspeed and DALT55 digital altimeter.)
