2. TechnicalrequirementsThe signs must comply with the requirements of FAA Advisory Circular AC 150/5345-44 (latest edition) and the following requirements: 2.1. EnvironmentalRequirements

Signs and all their required components must be designed for continuous outdoor use under ambient temperature range: minus 40 degrees to plus 55 degrees Celsius (Class 2 in compliance with AC 150/5345-44).

2.2. WindRequirement2.2.1. The sign must withstand without any sustaining damage or

breakage of the frangible mounting at wind velocity of up to: Mode 2 (322 kmh), in compliance with AC 150/5345-44.

2.2.2. If any special circumstances appear (sign location poses an increased safety risk arising from jet blast), the use of Mode 3 shall be necessary. This need will be defined by IAA.

2.3. Rain&dust

Signs must have a protection class of IP54 (or better) and withstand exposure to wind-driven rain and dust storms.

2.4. SunlightSigns must withstand exposure to prolonged direct sunlight without degradation of performance.

2.5. Electromagneticcompatibility2.5.1. The system to be installed, and any related subsystems, must not

cause any disturbance to other installed and operating systems at the airport, such as: ILS, vehicles, equipment and so on.

2.5.2. The following standards must be complied: IEC 61000-6-4 (regarding emission), IEC 61000-6-2 (regarding immunity) and FAA-EB 67.

2.6. Signsconstruction

2.6.1. The sign shall be delivered fully assembled and tested, with its mounting flanges, ready for installation.

2.6.2. The signs shall be lightweight for faciliting the handling and installation (maximum by two men for the longest signs), frangible, self-supporting and mounted on a concrete base.

2.6.3. Frangible coupling elements shall be necessary in order to cleanly break in case of impact. A solution in which the equipment is mounted on mounting legs where the mounting legs have a weakening groove that serves as a breakable coupling are also permitted.

6

2.6.4. Sign tether anchor hard points must be provided on one sign mounting leg above the frangible breaking point. Tether anchor hard points must be provided so that one end of the tether attaches to the sign structure, and the other end attaches below the frangible point on the coupling to either one of the leg mounting bolts or an independent bolt in the concrete mounting pad.

2.6.5. All materials used in fabrication of the signs and mounting hardware must be suitable for their purpose and protected against corrosion.

2.6.6. Signs face. Signs must be either single face with a message on one side or double face with a message on two sides.

2.6.7. Legend panel. 2.6.7.1. The message shall be displayed by means of appropriate

processes according to the operation but paint shall not be allowed under any circumstances.

2.6.7.2. Legend panels shall comprise several layers. A main layer thickness of ≥4 mm shall be required in order to improve resistance to high winds and jet blasts and to prevent it from shattering or cracking when hit by flying objects, i.e. stones picked up in a jet blast wash.

2.6.7.3. The remaining layers shall make up the colors and characters of the sign front, all covered in an anti-vandal, non-reflective translucent fascia. The sizing of sign characters and the spacing shall be directed by the appropriate International Standards, therefore, the length of individual signs shall be directly related to the display legend.

2.6.8. Signs lengths shall be according to one of the modules as specified in appendix 6 "DATA TABLE", table 6.1.

2.6.9. Signs Height shall be in accordance with the dimensions set either in FAA Advisory Circular AC 150/5345-44K or ICAO publications; Annex 14 volume I and Aerodrome Design Manual Part 4 for the Sign Sizes as follows:

Sign Size

Type (M=Mandatory) (I=Information) (L=Location) (RD=Remain

2.7. Lightsources2.7.1. Signs must be internally illuminated using LED lamps as light

sources. 2.7.2. Individual LED light bar/strip assemblies shall be used (no LED

light tubes shall be allowed). 2.7.3. The lifetime shall not be less than 50,000 hours (nominal lifetime

at operating current) and remaining at least at 70% (L70) of the initial luminous flux.

2.7.4. LED light sources must be designed to avoid chromaticity changes >0.007 on the CIE 1976 (u’, v’) Uniform Chromaticity Diagram, after the initial 6,000 hours of operation.

2.7.5. LED signs must not cause perceptible flicker to a moving human observer (example: pilot in an aircraft) throughout the range of brightness steps (FAA-EB 67). It also necessary that signs operated in a series lighting circuit must work at any current value within the circuit current range and must not flicker after stabilization of the selected current setting step per the time specified in AC 150/5345-10.

2.7.6. To ensure the safety of maintenance personnel, there shall be low regulated DC voltage (preferably no more than 240 VDC) at every point inside the sign and the LED power supply circuit shall have a maximum output regulated current of 500 mA.

2.7.7. Multi-lamp design is necessary in order to safeguard signal legibility in the event of partial light source failure.

2.8. Luminancerequirements

2.8.1. No reflectors will be allowed in order to meet photometric requirements.

2.8.2. Signs must meet the minimum luminance requirements set out in paragraph 3.2.5.6 (AC 150/5345-44) throughout the current ranges of the associated series circuit and uniformity factors of ICAO Annex 14 Vol I for operations conducted in runway visual range less than a value of 800m.

2.8.3. The luminance level and uniformity shall be maintained across all brightness steps of the CCR. The chromaticity of signs legends shall not be subject to color shifts during operation.

2.8.4. The photometric test will include the average luminance for all brightness steps of the CCR and color. Colors must comply with “CIE: Recommendations for Surface Colors for Visual Signaling - Publication No. 39-2 (TC-106) 1983 Fig. 4”.

2.8.5. Signs must create a very uniform distribution of light over the entire surface that eliminates hot spots and shadows as well as making signs more readable and improving visibility. The sign must ensure excellent legibility even in the worst visibility conditions and the front panel must be a reflection-free surface.

8

2.9. Electricalrequirements2.9.1. Signs must operate from a series lighting circuit with a current

range of 2.8 to 6.6 A (FAA-Style 3), being supplied from an appropriately sized 50 Hz isolation transformer (FAA L-830), so a power supply assembly shall be necessary. Rated frequency: 50 Hz (±7.5%)

2.9.2. External power switch for turn off the sign. Signs must include an ON/OFF power switch (preferably with cover) that is appropriate for turning the sign on/off. This switch will bypass the isolation transformer secondary current during maintenance activities.

2.9.3. All lighted signs must be equipped with a power input disconnect cable not less than 3 meter length terminated with a Type II plug under the requirements of AC 150/5345-26 and in compliance with AC 150/5345-44.

2.9.4. The power factor shall be greater than 0.95 across all brightness steps (series circuit),

2.9.5. The true power factor for all fixtures powered by a CCR must not be less than 0.80 (0.7 is specified in FAA-EB 67) when measured at the isolation transformer primary input power leads of the fixture on all constant current regulator current steps,

2.10. SignInternalLampFailure

The design must safeguard signal availability in the event of partial lamp failure. The failure of any light source within a sign must not result in a potential miscommunication of the intended message to a pilot. If the failure of an internal lamp(s) in a sign causes a panel or any section of a panel to be dark, or have an average luminance less than the minimum required (AC 150/5345-44), sign operation must be automatically discontinued.

2.11. Nameplaterequirements

Each sign must have a nameplate showing: - Type. - Size. - Style. - Class. - Manufacturer’s name and address. - Date of manufacture. - Catalog number. - Lamp data including the lamp type and rating.

Nameplates must be fabricated from materials that will resist fading and cracking arising from exposure to weather, salt-laden air, and sunshine. The material for the nameplate should be of the same or better durability than the sign frame material. Signs must be legibly identified throughout the unit’s service life.
