2.7 Interpretation of System Terminology
2.7.1 Elevation
The beam centers of all lighting fixtures in the PAPI system aim at the approach
slope according to the defined subtle deviation and the elevation means the included
angle of the beam center of the lighting fixtures and the horizontal plane.

2.7.2 Key Buttons and Plug-ins
The general framework of the PAPI control panel is shown in Figure below and
definitions of the key buttons and plug-ins are as follows:
SW1: Setting state switching jumper cap (switching between “Factory Mode”and
“User Mode”);
SW2: Mode switching button (switching between “Operation” and “Calibrate
Flight”);
J3: Main power source and light source receptacle;
J5: CAN adapter plate receptacle;
DS1: Four-digit Nixie tube.
SW1: Setting state switching jumper cap, which is used for switching between
“Factory Mode” and “User Mode”;
SW2: Mode switching button, which is used for switching between different state
modes under “User Mode”;
Rightmost J5 on the control panel is an interface reserved for CAN adapter plate,
through which the data of the control panel may be transmitted to the monitoring
system. J3 near the middle is a key connector, through which all power cables, power
source cables and buses are connected with the external cables.

After this system is powered on, the panel control will automatically enter
“Operation”and have the function to automatically recover “Operation” with
unmanned operation under “Calibrate Flight” to prevent misoperation by the airport
personnel.
Four-digit Nixie tube: There is a four-digit Nixie tube embedded on the PAPI
control panel (as shown in Figure DS1 below), which timely displays the current
mode and elevation of PAPI. The angle displayed by the Nixie tube has four
characters, with the first character of a letter, showing the state of PAPI and the last
three characters showing the “current angle”.

2.7.3 Two Working Conditions and Four Modes
This PAPI system has two working conditions and four modes, whose relations
are shown in Figure below:
“Factory Mode” and “User Mode” of PAPI are switched through SW1.
(1) “Factory Mode”:
When PAPI is in “Factory Mode”, the Nixie tube only displays the current angle.
“Factory Mode” is only used for the standard calibration of PAPI when it leaves the
factory, or clearing the angle when the control panel of PAPI is replaced. During daily
normal use, the user shall not enter “Factory Mode”. Otherwise, the Nixie tube will
reset and “Memory Angle” of the system will be automatically cleared, as shown in
Figure below:
Display under “Factory Mode”
■ Switching SW1 randomly is strictly prohibited.
※To enter the Factory Mode may cause loss of data in the PAPI
system.
■ Metal articles close to SW1 is strictly prohibited.
※Otherwise it may cause automatic trigger of SW1, resulting in loss
of data in the PAPI system.

(2) “User Mode”:
When PAPI leaves the factory, the system is in “User Mode” and PAPI executes
various operations.
“User Mode” includes “Calibrate Flight” and “Operation”, which are fixed
programs of the lighting fixtures. Under “User Mode”, SW2 is used for switching of
various modes and the user may switch “Calibrate Flight” and “Operation” through
SW2.
Under “User Mode”, the PAPI system may have “Error” under certain state. After
PAPI enters “Error”, the system will automatically turn off the lamp.
Under “User Mode”, the PAPI system support stores the current angle into the
system and displays the “Memory Angle” through the Nixie tube.
During daily use, the user shall not switch the jumper cap of SW1. SW1 shall be
switched only when the user replaces the control panel and the system shall be set to
“Factory Mode”.

(3) “Calibrate Flight”
During flight calibration or daily maintenance, the system shall set PAPI to
“Calibrate Flight”. Under this mode, PAPI will not have “Error”, but turn off the lamp
to ensure normal on-going flight calibration or maintenance. The display method of the
four-digit Nixie tube is 4 characters initiated by the letter C (the Nixie tube displays
“C+ value of the current elevation”), with the display shown in Figure below:
Display under “Calibrate Flight”
The above-mentioned Nixie tube information means that PAPI is in “Calibrate
Flight” and the current angle is 2.58.
Under this mode, the angle displayed by the Nixie tube is immediate. When the
real angle of PAPI has any subtle change, the angle of the Nixie tube will be changed
accordingly.
“Calibrate Flight” will automatically recover to Operation after 8h with unmanned
operation to prevent misoperation by the airport personnel.

Advanced Airport Lighting System
19
(4) “Operation”
After this system is powered on, the control panel will automatically enter
“Operation”.
Under “Operation”, PAPI works normally and achieves control of various states,
including such preset functions as error alarm. Therefore, after the flight calibration or
daily maintenance is completed, PAPI is switched to “Operation” from “Calibrate
Flight” through the SW2 button. The display method of the four-digit Nixie tube is 4
characters initiated by the letter A (the Nixie tube displays “A+ value of the current
elevation”), with the display shown in Figure below:
Display under “Operation”
The above-mentioned Nixie tube information means that PAPI is in “Operation”
and the current angle is 2.58.
Under this mode, the angle displayed by the Nixie tube is immediate. When the
real angle of PAPI has any subtle change, the angle of the Nixie tube will be changed
accordingly.
■ PAPI must be set to “Operation” for work.
※PAPI cannot achieve error alarm.
It must be recorded and the user shall record this value in the relevant document
according to the provisions.

(5) “Memory Angle”:
Press the SW2 button for longer than 5s to store the current angle confirmed
through flight calibration into the PAPI system. We call the angle stored into the
system “MemoryAngle”.
The expression form of “Memory Angle” is four characters initiated by the letter
F displayed by the four-digit Nixie tube (the Nixie tube displays “F+ currently memory
angle”):
Display under “Memory Angle”
The above-mentioned Nixie tube information displays “Memory Angle” and the
angle recorded into the system is 2.50.
When the PAPI under “Operation”, the Nixie tube alternately displays the current
angle and memory angle with 5s as a circle. It displays the “Memory Angle” at 2s and
“Current Angle” at 3s. The user may understand the difference between the current
real angle of PAPI and previously memory angle of the flight calibration.
For example, the current operating angle is “A2.58”. When the current “Memory
Angle” (design angle) is “F2.50”, the Nixie tube will display the following two legends
alternately:
Display at 2s
Display at 3s
These two data are displayed alternately under “Operation”.
Take the above-mentioned Figures as examples, although the difference between
the current operating angle and the current memory angle is 0.08°, it is still within the
allowable range and PAPI will not have any action.
■ As an important datum, the “Memory Angle” shall not be
changed randomly.
※Otherwise it may cause PAPI have no standard, so as to
generate misoperation.
