22. 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. Fixture Alignment – UEL
Standard Alignment Device

24. Fixture Alignment – UEL Standard Alignment Device
Procedure
Step
Description 1
Remove the optical cartridge and install the levelling device in its place.
Tighten the securing screw. 2
Set the elevation angle on the setting device and the azimuth (toe-in)
angle on the sighting device. 3
Level the light approximately to allow the azimuth orientation of the light. 4
Set 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. Fixture Alignment – UEL Standard Alignment Device
Procedure
Step
Description 5
Secure the bracing clamp of the light. 6
Use 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. 7
Remove the device. Put the optical cartridge back in place, without
forgetting to connect the lamp.

26. 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. Fixture Alignment – UEL
Electronic Alignment Device

28. Fixture Alignment – UEL Electronic Alignment Device
Step
Description 1
Lower the mast. 2
If 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. 3
Remove the optical cartridge and install the levelling device in its place.
Tighten the securing screw. 4
Raise the mast. Operate the switch to take a measurement.

29. Fixture Alignment – UEL Electronic Alignment Device
Step
Description 5
Lower the mast and read the angle indicated on the digital display.
Calculate the difference between the real angle and the required one. 6
If 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). 7
Raise the mast and repeat the operation 6 until the adjustment is correct. 8
Lower the mast and remove the device. Put the optical cartridge back in
place, without forgetting to connect the lamp.

30. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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.

40. Fixture Alignment – FAE

41. Fixture Alignment – FAE Standard Mounting Device

42. Fixture Alignment – FAE Standard Mounting Device
3. Level the light approximately to allow the azimuth orientation of the light.
4. Orient the light in the correct position (generally parallel to the runway axis) using the sighting device.
If there is no light in the same alignment, use a reference pole. Otherwise, use another light (installed at the same distance of the axis).

43. Fixture Alignment – FAE Standard Mounting Device
5. Secure the three light fastening screws to the support.
6. Use the spirit level to set the light at the correct elevation by unscrewing/screwing slightly the two opposite screws.
7. Remove the device.

44. Fixture Alignment – FAE Electronic Mounting Device
The system consists of a support similar to the one used with the standard simplified mounting device.
However, the support is equipped with a sensor connected to a remote digital display through a 10 m long cable. The operator can then read the angle setting from the
ground.

45. Fixture Alignment – FAE
Electronic Mounting Device
Lower the mast.
Set the device to the light body.
Raise the mast.
Read the angle indicated on the digital display.
If necessary, correct and repeat the operation.

46. Fixture Alignment – FAE
Electronic Mounting Device
During the approach installation, another method consists to use a platform for an easy initial adjustment with the operator at the light level.
A flight check shall be performed to detect gross misalignment in the approach and runway threshold lighting system.
Errors shall be corrected and the system shall not be put in operation until it has
been found satisfactory during the flight test.

50. Elevated Fixture Alignment (LED EREX)
L-880/L-881 PAPI Training Instructor Notes
The fixture is aligned in azimuth by looking at a reference mark through the alignment tool.
Depending on the position of the fixture, the reference mark may be another light in the same row
or a stick installed for this purpose. Usually, for runway edge lights another light of the same row
is used.
For threshold / runway end lights, a stick can be installed in the prolongation of the line of
the threshold / runway end lights

69. In-pavement Light Training
Transport Canada CASA
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.
Always use a two-part locking washer assembly with in-pavement light fixtures.
Always use new bolts and washer assemblies. Never reuse bolts.
Copyright © 2010 by ADB Airfield Solutions. All rights reserved.

70. In-pavement Light Training
Transport Canada CASA
Never leave a fixture with a bolt missing. Missing bolts place additional stress on the fixture as well as the remaining bolts.
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.
