R (1) Drain the standby air data system (Ref. TASK 12-24-34-600-001).
R (2) Remove the slip on covers from the standby static probes and the
R standby pitot probe and connect the GENERATOR - GROUND PRESSURE MINI.
R 100 MB (1.45 PSI) TO 1400 MB (20.3 PSI) to :
R - the L or R standby static probe with the ADAPTER COVER-STATIC PORT
R (98D34003500100).
R - the standby pitot probe with the ADAPTOR-CHARGING,PITOT PROBE.
R NOTE : The ADAPTOR-CHARGING,PITOT PROBE is on the drain hole. Thus it____
R is not necessary to seal the drain hole of the pitot probe.
R (3) Seal the opposite standby static probe with the piece of plastic and
R with the STATIC PORT COVER (98D34003500103) from the ADAPTER COVER-
R STATIC PORT..
R (4) Precautions
R CAUTION : OBEY THESE PRECAUTIONS WHEN YOU DO THE TEST TO PREVENT_______
R DAMAGE TO INSTRUMENTS:
R - PRESSURE SET MUST NOT BE MORE THAN 1050 hPa (31 in Hg) OR
R LESS THAN 115 hPa (3.39 in Hg)
R - CHANGES IN PRESSURE MUST NOT BE MORE THAN 6000
R FEET/MINUTE
R - DO NOT SUDDENLY OPEN LINES TO AMBIENT AIR WHILE THE
R PRESSURE GENERATOR IS CONNECTED.
R CAUTION : THE TOTAL PRESSURE IN THE PITOT SYSTEM MUST NEVER BE LESS_______
R THAN THE STATIC PRESSURE. THE DIFFERENCE BETWEEN THE PITOT
R AND THE STATIC PRESSURE CIRCUITS MUST NEVER BE MORE THAN
R 368 hPa (10.86 in Hg).
R (5) Start the ground pressure generator.

Subtask 34-21-00-720-050

A. Test of the Standby Airspeed Indicator
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
On the ground pressure generator :
-
set a static pressure of 314.8 hPa (29,000 ft)

-
set an impact pressure of 200.1 hPa (340 Kts).

-
set a static pressure of 571.8 hPa (15,000 ft)

-
set an impact pressure of 153.5 hPa (300 Kts).

-
set a static pressure of 843 hPa (5000 ft)

-
set an impact pressure of 53.5 hPa (180 Kts).

On the standby airspeed indicator:
-
the pointer shows 340 Kts (+ or - 5Kts).

-
the pointer shows 300 Kts (+ or - 4Kts).

-
the pointer shows 180 Kts (+ or - 3Kts).
