FUNCTION

NO. 2 SNSR Test Point

Provides monitoring capability for signal output of No. 2 airspeed sensor.

When mode selector control is at NORM, NO. 1 SNSR test point is connected

to NO. 1 SIM test point.

NO. 2 SIM Test Point

Provides monitoring capability for No. 2 airspeed sensor simulation signal

when mode selector control is at SIM STAB 1 & 2 or SIM STAB 2. Provides

monitoring capability for 2.26 vdc (simulated signal output from airspeed sen-

sor from 0 to 30 knots of airspeed) supplied to No. 2 stabilator amplifier when

mode selector control is at SIM STAB 1. When mode selector control is at

NORM, NO. 1 SIM test point is connected to NO. 1 SNSR test point to pro-

vide monitoring capability for signal output of No. 2 airspeed sensor.

DECR/INCR Control

Supplies variable dc simulation signal, with voltage range of less than 2.0 vdc

and not greater than 15.0 vdc, through selected SIM of mode selector control,

to specific amplifiers selected. Simulation voltages, which are selected by mode

selector control and supplied through test set connector J1 to No. 1 stabilator

amplifier, can be monitored at NO. 1 SIM test point. Simulation voltages,

which are selected by mode selector control and supplied through test set con-

nector J2 to No. 2 stabilator amplifier, can be monitored at NO. 2 SIM test

point. Turning control in INCR direction increases positive voltage output from

test set. Turning control in DECR direction decreases positive voltage output

from test set. Test set variable dc signal output is equal to 75 millivolts per

knot of simulated airspeed.

Mode Selector Control

NORM position supplies output from No. 1 and No. 2 airspeed sensors

through test set connectors J1 and J2, to No. 1 and No. 2 stabilator amplifiers,

respectively. Signals from No. 1 airspeed sensor can be monitored at NO. 1

SNSR and NO. 1 SIM test points. Signals from No. 2 airspeed sensor can be

monitored at NO. 2 SNSR and NO. 2 SIM test points. OFF position opens

input to stabilator amplifier to test amplifier's auto shutdown function. SIM

STAB 1 & 2 supplies variable dc simulation signal selected by DECR/INCR

control through test set connectors J1 and J2, to No. 1 and No. 2 stabilator

amplifiers, respectively. These simulation signals can be monitored at NO. 1

and NO. 2 SIM test points. SIM STAB 1 supplies variable dc simulation signal

selected by DECR/INCR control through test set connector J1, to No. 1 stabi-

lator amplifier. This simulation signal can be monitored at NO. 1 SIM test

point. This switch position also supplies 2.26 vdc (simulated signal output

from airspeed sensor from 0 to 30 knots of airspeed) through test connector J2,

to No. 2 stabilator amplifier. This 2.26 vdc can be monitored at NO. 2 SIM

test point. SIM STAB 2 supplies variable dc simulation signal selected by

DECR/INCR control through test set connector J2, to No. 2 stabilator ampli-

fier. This simulation signal can be monitored at NO. 2 SIM test point. This

switch position also supplies 2.26 vdc (simulated signal output from airspeed

sensor from 0 to 30 knots of airspeed), through test set connector J1, to No. 1

stabilator amplifier. This 2.26 vdc can be monitored at NO. 1 SIM test point.
