95.2.2.6 Slowly open pressure vent valve.
Check that airspeed indication returns to a
minimum limit.
CAUTION
DO NOT DISCONNECT A LINE OR
REMOVE A FITTING TO VENT
SYSTEM WHILE UNDER TEST AS
DAMAGE TO INSTRUMENTS MAY
OCCUR.
95.2.2.7
Pump vacuum side until sufficient
vacuum for test is indicated on the vacuum dial.
Vacuum in the tank may be replenished as
required during the test.
95.2.2.8
Slowly and gradually open vacuum
source valve. Check that both altimeter and
airspeed indicator readings increase and that
vertical speed indicator shows a positive rate of
climb.
CAUTION
VALVES ON TEST SET ARE
SENSITIVE AND SHOULD BE
OPERATED SLOWLY AND WITH
CARE TO AVOID POSSIBLE
DAMAGE TO INSTRUMENTS.
CLOSELY MONITOR BOTH
HELICOPTER AND TEST SET
INSTRUMENTS TO ENSURE THAT
NO INDICATOR MAXIMUM
LIMIT IS EXCEEDED.
95.2.2.9 Slowly increase airspeed to
approximately 80 knots and close vacuum
source valve and pressure vent valve. Hold
airspeed at around 80 knots and increase altitude
by manipulating the crossfeed and vacuum
source valves. At approximately 2000 feet above
current indication close both the crossfeed and
vacuum source valves. Verify pilots altimeter
reads with +/- 20 feet of test set indicator, and
that after 1 minute, indicated loss of altitude shall
not exceed 100 feet. Check that vertical speed
indication is zero or negative, not exceeding 100
fpm.
CAUTION
DO NOT DISCONNECT A LINE OR
REMOVE A FITTING TO VENT
SYSTEM WHILE UNDER TEST AS
DAMAGE TO INSTRUMENTS MAY
OCCUR.
95.2.2.10 Slowly open vacuum vent valve and
observe pilots altimeter and test set altimeter
returns to previous indicated altitude.
95.2.2.11 Slowly open pressure vent valve and
observe pilots airspeed and test set indicator
returns to minimum limit.
95.2.2.12 Remove hoses and tape installed in
step 95.2.2.1.
95.2.2.13 Repeat above steps 95.2.2.1 through
95.2.2.12 for copilots airspeed indicator and
altimeter.
