standards FAA and ICAO.
Theprecautionsprovidedinthemanualarealwaysprecededbyasymbolasillustratedbelow:
Indicates the warnings, the notes, the suggestions and other points on which is intended to
draw the attention of the reader.
Indicates the operations to be carried out mandatorily or the information which should be
carefully read to avoid possible risks.
Indicates particular risks connected with the power supply. It reports the operations to be
carried out mandatorily or the information which should be carefully read to avoid possible
risks.
Theseprecautionssafeguardthepersonalsecurityofeveryonewhoworkonand/orareinproximityoftheequipment
andoftherelativesupplycircuits.
The failure to comply with the instructions (in particular those preceded by danger, warning, caution
precautions) can cause serious injury or death.
1.3 Safety instructions
CAREFULLY READ THIS DOCUMENT.
The improper use of the equipment or the failure to comply all the precautions indicated
implies life danger and serious injury to persons and damages to things.
HAZARD OF ELECTRICAL SHOCK, EXPLOSION OR ELECTRIC ARC
Carefully read the enclosed documentation before installing or starting to use the equipment.
Do not install the equipment until the completion of all construction works required to carry
out the work.
DO NOT OPERATE ON POWERED CIRCUITS
Do not carry out any operation on powered circuits.
Beforeeveryaccess,inspectionorinterventionontheequipment,ensuretohaveswitchedo󰀨the
equipmentbyopeningthemainpowerswitchandbyremovingthesupplyfromtheunit(openthe
powerswitchatthebeginningofthelineorswitcho󰀨theconstantcurrentregulator).
The failure to comply all the precautions indicated implies life danger and serious injury to

2.4 Method of calculation of the installation parameter
ToproperlyinstallthePAPI401systemthefollowingparametersmustbeassessed:
●DX: actualdistanceofthefrontleginrelationtothethreshold
●QC: elevationoftheconcreteplatforminrelationtothethreshold
2.3 Wiring
ThePAPI401systemmustbepoweredbyacircuitairportseries(6.6A).
In case of double PAPI system, installed both right and left of the landing runway (or of the
helipad), each branch should be powered by a di󰀨erent series circuit. Thus congured, the
failure of a power supply circuit causes the failure to function on only one of the two blocks.
In case of single PAPI system, installed only on the right and on the left of the landing runway
(or in front of the helipad), is appropriate to use a single circuit to power the unit.
Using two di󰀨erent circuits to power the lamps of a single unit, the fault of a circuit can
generate a misreading of the xture inducing the pilot into error.

Thesignallingdevices,incombinationwithhorizontalandverticalxtures,provideinformationtothepilotsand
thereforerepresentafundamentaldrivingaid.
Thesedevicesmustalwaysbeinoperatingconditionandmustbeclean,maintainedand,ifnecessary,replaced
assoonastheirvisibilityisa󰀨ected.
Thelightsourcesmustbepositionedaccordingtothelegislativeprovisionsneartherunwayorientedtowardsthe
approachdirectiontothelandingrunway.Theopticalaxisoftheunitmustbeparalleltotherunwayedge.The
positioningofthelightunitsoftherunwaymustbeincompliancewithcurrentregulations.
For the positioning of the xtures always refer to the requirements of the relevant Standards:
