22 Slide Header 1 Presentation Title TrebuchetBold 20pt 09/29/ Fixture Alignment – UEL Standard Alignment Device This system is suited for ground mounted lights or pole mounted lights up to 2 m. It consists of a support, which is secured on the light unit, in the place of the optical cartridge, and which is equipped with a elevation angle setting device, a sighting device (both with a graduated scale) and a spirit level. The elevation angle setting device is graduated from 0 to 25 degrees. For the azimuthal setting, the system can be rotated around a vertical axis, and has 4 set positions that allow aiming at reference points (generally other lights) in a direction parallel or perpendicular to the centre line. The sighting device is graduated from -4 to +4 to allow for toe-in angles.

23 Slide Header 1 Presentation Title TrebuchetBold 20pt 09/29/ Fixture Alignment – UEL Standard Alignment Device

24 Slide Header 1 Presentation Title TrebuchetBold 20pt 09/29/ Fixture Alignment – UEL Standard Alignment Device Procedure StepDescription 1Remove the optical cartridge and install the levelling device in its place. Tighten the securing screw. 2Set the elevation angle on the setting device and the azimuth (toe-in) angle on the sighting device. 3Level the light approximately to allow the azimuth orientation of the light. 4Set the light in the correct direction using the sighting device, aiming at the next or former light in the same alignment. For lights in a barrette, a side row or a wing bar, aiming laterally at another light is possible. For this purpose release the two locking levers, turn the system by 90° until a distinct click can be felt, and retighten the locking levers. If there is no light in the same alignment, use a reference pole.

25 Slide Header 1 Presentation Title TrebuchetBold 20pt 09/29/ Fixture Alignment – UEL Standard Alignment Device Procedure StepDescription 5Secure the bracing clamp of the light. 6Use the spirit level to set the light at the correct elevation by unscrewing/ tightening slightly the two opposite screws. Tighten the screws sufficiently to avoid any play, but do not overtighten them. Once this is done, secure the two counter-nuts. 7Remove the device. Put the optical cartridge back in place, without forgetting to connect the lamp.

26 Slide Header 1 Presentation Title TrebuchetBold 20pt 09/29/ Fixture Alignment – UEL Electronic Alignment Device This system is suited for fittings mounted on safety approach masts, when it is not possible to get access to the top of the mast in its standing position. The system consists of a support similar to the one used with the standard simplified leveling device. However, the support is equipped with a sensor activated with a switch, with a 10 m long cable. The operator can then operate the sensor from the ground, and read the elevation angle measurement when the mast is tilted to the ground. Note: During the installation of the approach line, a quicker method is to use a platform at the light level for an easy initial adjustment.

27 Slide Header 1 Presentation Title TrebuchetBold 20pt 09/29/ Fixture Alignment – UEL Electronic Alignment Device

28 Slide Header 1 Presentation Title TrebuchetBold 20pt 09/29/ Fixture Alignment – UEL Electronic Alignment Device StepDescription 1Lower the mast. 2If the mast has been correctly installed, i.e. its tilting axis is perpendicular to the centre line, a light with 0° toe-in will have its front surface fully horizontal when the mast is tilted over 90° (down to the horizontal). With the mast in this position, adjust the light by turning it around the tube, and then tighten the bracing clamp. For lights with a toe-in, first adjust the light for 0° toe-in. Make a reference mark on the tube just below the zero mark at the bottom of the slip fitter. Using the graduated scale, turn the light around the tube to the desired toe-in, and tighten the bracing clamp. 3Remove the optical cartridge and install the levelling device in its place. Tighten the securing screw. 4Raise the mast. Operate the switch to take a measurement.

29 Slide Header 1 Presentation Title TrebuchetBold 20pt 09/29/ Fixture Alignment – UEL Electronic Alignment Device StepDescription 5Lower the mast and read the angle indicated on the digital display. Calculate the difference between the real angle and the required one. 6If necessary, adjust the elevation angle by unscrewing/tightening slightly the two opposite screws. Tighten the screws sufficiently to avoid any play, but do not overtighten them. Once this is done, secure the two counternuts. While doing the correction, two measurements means are useable: - The elevation scale on the side of the light body (coarse measurement); - The levelling device itself, by taking a measurement before and after correction (fine measurement). 7Raise the mast and repeat the operation 6 until the adjustment is correct. 8Lower the mast and remove the device. Put the optical cartridge back in place, without forgetting to connect the lamp.

30 Slide Header 1 Presentation Title TrebuchetBold 20pt 09/29/ Fixture Alignment – UELC Electronic Alignment Device Calibration Procedures To calibrate electronic level, turn level on and place the level on a clean smooth, flat surface. Wait ten seconds. Push and hold the CALIBRATE button for 2 seconds. “CAL1” will appear briefly on the display.

31 Slide Header 1 Presentation Title TrebuchetBold 20pt 09/29/ Fixture Alignment – UELC Electronic Alignment Device Rotate the level end for end. Wait 10 seconds Push the CALIBRATE button again. “CAL2” will appear briefly on the display. The electronic level has been calibrated for level.

32 Slide Header 1 Presentation Title TrebuchetBold 20pt 09/29/ Fixture Alignment – UELC Electronic Alignment Device Remove the existing optical/lamp assembly from the UELC fixture to be aimed. Install the aiming device on the light unit in its place as shown. On the UELC fixture, engage the latch over the pin on the aiming device to hold it secure to the unit.

33 Slide Header 1 Presentation Title TrebuchetBold 20pt 09/29/ Fixture Alignment – UELC Electronic Alignment Device Mounting Tolerance – The vertical and lateral tolerance with respect to an individual light center within a barrette of lights shall be +/- 3 cm. Prior to aiming the light units, the structures on which the fixtures are to be mounted must be leveled vertically and horizontally to ensure proper aiming of the fixtures. Mounting columns must be plumb both perpendicular and parallel to the runway centerline. Tower cross arms must be leveled horizontally. Mount the fixture securely to the mounting column but do not over tighten. Ensure that all three mounting screws are equally tight. The fixture should be able to be rotated by loosening the front screw only.

34 Slide Header 1 Presentation Title TrebuchetBold 20pt 09/29/ Fixture Alignment – UELC Electronic Alignment Device Horizontal aiming is performed by use of the rear “V” site and the front clear line site. A forward alignment point is surveyed approx. 20 – 30 m in front of the light. Alternately, a light in the preceding approach barrette can be used as an alignment point.

35 Slide Header 1 Presentation Title TrebuchetBold 20pt 09/29/ Fixture Alignment – UELC Electronic Alignment Device Install the approach light fixture on its mounting and lightly tighten the three slipfitter bolts equally to snug the fixture to the mounting. Install the aiming device on the approach light fixture and by looking through the rear site of the aiming device, rotate the fixture until the front site is aligned with the fixture or survey mark directly in front of the light unit. Rotate the fixture until the alignment point is centered on the clear line site and the vertical line sight is centered in the “V” site. If necessary, the site can be rotated vertically by loosening the knurled screw on the side plate. This is useful when the aiming mark is lower that the fixture mounting level. Ensuring that the fixture does not rotate, adjust the two side slipfitter bolts until the unit is level. Tighten the front slipfitter bolt to lock the unit to the mounting. Tighten the locking nuts on all three slipfitter bolts.

36 Slide Header 1 Presentation Title TrebuchetBold 20pt 09/29/ Fixture Alignment – UELC Electronic Alignment Device Should a specific horizontal toe-in be required, the horizontal aiming point shall be established through surveying to give the appropriate toe-in angle (typically 3º). Please see below for the method of determining toe- in angle.

37 Slide Header 1 Presentation Title TrebuchetBold 20pt 09/29/ Fixture Alignment – UELC Electronic Alignment Device Vertical Aiming Once the horizontal leveling of the fixture is completed, the vertical aiming angle can now be set. Ensure that the digital level is calibrated in accordance with the instructions above and that the level is properly installed in the aiming device. The screws securing the digital level to the aiming device must be located on the bottom of the mounting holes. While tightening the securing screws, press down lightly on the aiming device to ensure that is properly seated.

38 Slide Header 1 Presentation Title TrebuchetBold 20pt 09/29/ Fixture Alignment – UELC Electronic Alignment Device Turn on the digital level and allow a few seconds for the display to stabilize. Carefully turn the FRONT aiming bolt until the digital readout on the level indicates the correct aiming angle for the approach position. Secure the vertical aiming angle by tightening the rear aiming bolt. Confirm the aiming angle is as required and readjust if required. Tighten the locknuts on each aiming screw to secure.

39 Slide Header 1 Presentation Title TrebuchetBold 20pt 09/29/ Fixture Alignment – UELC Electronic Alignment Device Recommended Aiming Check Intervals The following are the recommended intervals for the checking of the approach aiming angles: a) After initial installation – every 3 months for the first year. b) Then every 6 months.

68 Slide Header 1 Presentation Title TrebuchetBold 20pt 09/29/ New FAA Cert Alert and Transport Canada CASA due to several incidents in which in-pavement fixtures came out of the ground Transport Canada CASA

69 Slide Header 1 Presentation Title TrebuchetBold 20pt 09/29/ Torque the bolts used with inpavement lights to the manufacturer’s recommendations. Always use a calibrated torque wrench. Never use an impact driver because this could cause over-torque of the bolts. Installed bolts require periodic checks to ensure they remain at the required torque. 2.Always use a two-part locking washer assembly with in-pavement light fixtures. 3.Always use new bolts and washer assemblies. Never reuse bolts. Transport Canada CASA

70 Slide Header 1 Presentation Title TrebuchetBold 20pt 09/29/ Never leave a fixture with a bolt missing. Missing bolts place additional stress on the fixture as well as the remaining bolts. 5.When maintenance other than simple cleaning is required, removal of the light fixture and replacement with a refurbished unit is necessary. Although AC offers a recommended schedule for periodic checks, they should be tailored to the facility based on local conditions such as environmental issues and runway traffic load. Transport Canada CASA

71 Slide Header 1 Presentation Title TrebuchetBold 20pt 09/29/ In addition to conducting the required maintenance, airport operators must also ensure these maintenance activities are properly documented. If you are responsible for a Part 3 certificated airport and have any questions about documentation requirements, contact your assigned Airport Certification Safety Inspector. Transport Canada CASA
