INTEGRATED STANDBY INSTRUMENT (ON AIRPLANES 9159 AND SUBSEQUENT)
The Integrated Standby Instrument (ISI) displays standby attitude, altitude, airspeed, Mach number,
slip−skid indication, ILS deviation, corrected altitude, barometric pressure and VMO/MMO. It also
calculates the Static Source Error Correction (SSEC).
The ISI is a selfcontained
instrument which receives pitot pressure input from the standby PS and
static pressure input from PS 1 and the standby PS. It is powered by 28 VDC. The ISI also receives
inputs from the SPS to compute the SSEC.
Operation of the ISI is accomplished with the use of a BARO rotary knob and 4 push−buttons: CAGE
(gyro−caging), STD (baro−settings), + and −. The CAGE button resets the horizon line when the
button is depressed for more than 2 seconds. A warning flag appears on the display when
re−alligning. When depressed, the STD button will select the standard pressure reference of 1013
hPa or 29.92 inHg. The BARO knob can be used to adjust the baro−correction pressure. The + and −
buttons are used to control the brightness of the display.
Fault detection is achieved through the BuiltIn
Tests (BIT). When a failure is detected, the data at
fault is removed from the ISI and the applicable warning flag (ILS and SSEC) or cross (attitude,
altitude, LOC and G/S) is displayed.

CLOCK
Two digital clocks synchronized to GPS time and date from GNSSU No. 1 are installed in the cockpit.
The clocks provide time and date information for the avionics equipment. Each clock provides GPS
or internal time and date, local time, chronometer and elapsed time functions. The clock
automatically enters GPS mode when the clock receives a valid GPS signal and automatically enters
Internal mode if the GPS signal becomes invalid.
When power is initially applied to the clock and GPS is invalid, the clock enters SET mode and all
functions can be set in sequence. The clock will enter normal operation by pressing the MODE
button for 2 seconds.
After the clock has been set via GPS or manually, changing the time and date is accomplished by
entering each mode individually and pressing the MODE button for 2 seconds. When setting is
finished, press the MODE button for 2 seconds to enter normal operation.
NOTE
If GPS is valid, only local time can be changed.

decrease data during time setting.
ET RST Pushbutton
Resets the elapsed timer (only

increase data during time setting.
MODE Pushbutton
Controls selection of DT,
GPS/INT or LT mode.
Used in conjunction with the
ET SEL/RST pushbuttons to
set time and date.
CHR Pushbutton
Controls the start, stop and reset
function of the chronometer display.
ET/CHR Display
Displays elapsed time or chronometer
time. ET in hours and minutes and
CHR in minutes and seconds.

TIME SETTING
Set at Power−up
At the first application of power, the clock will be in GMT minutes adjustment if GPS is invalid and
the clock is not trans,itting on the ARINC bus. If the GPS data is valid, the clock is automatically
updated and switched in GPS mode.
In the SET function, the GMT minute’s digits are flashing. The flashing rate is 1e flash per second.
The setting is obtained by pressing the ET SEL pushbutton to decrease the data and pressing the
