3 Section 1 MALMS Photometric Measurement Systems Introduction The has been developed specifically to accurately measure the performance of High Intensity Lighting on airfield runways. MALMS provides information for both regulatory authorities and airfield operators in a fast and efficient manner and has been developed by Tailor Made Systems Ltd following an extensive research program, commissioned by the Civil Aviation Authority, into the performance of high intensity lighting as installed at major airfields. The MALMS Mobile Standard system comprises: Trailer mounted MALMS Mobile Data Collection System. PC based MALMS Data Analysis System for data storage, analysis and output. MALMS Workshop Tester (optional), for testing fittings prior to return to service. MALMS measures both inset and elevated runway and taxiway fittings. It has been designed to measure performance against the criteria for beam intensity and orientation defined in ICAO Annex 14, using the test methodology that Annex 14 specifies. MALMS is therefore suitable to confirm compliance with National and International Standards. It also provides information to identify problems, develop maintenance strategies and produce work schedules / maintenance reports. Extended trials on operational airfields have proved that the MALMS Differential Maintenance strategy, which targets maintenance when and where required, enables system performance to be improved without additional resources. If required the MALMS system can be extended to provide an integrated maintenance system to close the maintenance loop and ensure that maximum benefit is obtained from finite resources and limited runway access time.

In use around the World - By airfields, Civil Aviation Authority and Ministry of Defence Issue: 10.2 September 2008 Page 4 of 50

5 Section 1 MALMS Photometric Measurement Systems The Benefits Enables compliance with ICAO Standards CAA research has shown that only by regular measurement and targeted work can AGL lighting be brought up to, and maintained at, the ICAO standard. MALMS identifies individual units that are under-performing thereby enabling maintenance to be focused on them. MALMS can then measure the effectiveness of maintenance undertaken and schedule further work on any units that still fail to meet the standard. Identification of Major Contamination Problems Occasionally (such as following construction work or application of ant-icing fluid) performance of the complete runway may be degraded. MALMS provides a fast way to establish the extent that performance has been affected by such activities and establish the priority of cleaning. Reduce Maintenance Costs Targeting work when and where required means that standards are maintained with minimum effort. MALMS ensures that resources are not wasted on fittings that are performing acceptably. Prioritise Maintenance Work Often the resources available do not match the work load. MALMS can prioritise work such that it can be scheduled efficiently. Minimise Runway Time Access time on runways is very restricted. MALMS is fast - data collection speed is normally limited by driving quality. Speeds in excess of 65 km/h are practical. Issue: 10.2 September 2008 Page 5 of 50

6 Section 1 MALMS Photometric Measurement Systems Confirm RVR Values RVR (Runway Visual Range) is normally calculated from measured visibility, assumed light intensity and other factors. MALMS can confirm that the assumed light intensity is maintained and thus the quoted RVR values are valid. Monitor Maintenance It has traditionally proved difficult to monitor maintenance work. MALMS provides a detailed Isocandela Diagram of every fitting on each survey run, which can be used to monitor maintenance work. Commissioning / Acceptance Tests Undertaking a detailed survey of system performance is impractical with existing techniques. MALMS quickly measures both beam intensity and orientation, so that correct installation and alignment can be confirmed. Issue: 10.2 September 2008 Page 6 of 50

7 Section 1 MALMS Photometric Measurement Systems Effectiveness Extended trials on operational airfields have demonstrated that the use of MALMS based Differential Maintenance enables system performance to be improved without additional resources. With Differential Maintenance - measuring performance on a regular basis and targeting maintenance on the under-performing fittings - the performance of an installation can be brought up to standard quickly. Targeting work on those fittings that are under-performing ensures that maximum benefit can be obtained from maintenance activity thereby minimising wastage and enabling maintenance expenditure to be optimised. The MALMS Performance Charts below show the benefit achieved by the application of MALMS to control maintenance at a UK airfield: Pre MALMS In the charts each vertical bar represents the main beam intensity (as % of ICAO Standard) of an individual fitting and is colour coded to provide a visual indication of status (green=pass, blue=unclassified, red=fail). MALMS identified a deterioration in optical performance that could not be measured with traditional techniques and which had prevented the required standards being met. Post MALMS MALMS information enabled improvements to maintenance techniques, supervision and quality control. These resulted in a significant improvement in overall performance.

8 Section 1 MALMS Photometric Measurement Systems Background AGL systems are installed to enable suitably equipped aircraft to operate safely under low visibility conditions. Since RVR (Runway Visual Range) is based on an assumed value for light intensity the performance of lighting equipment is an important factor in maintaining safety and Landing Success Rates. In the past airfield and regulatory authorities have had to rely on visual observations or spot readings with a light meter to determine the performance of High Intensity Lighting. These have been proven to give an inaccurate measurement of beam intensity and cannot identify beam orientation. The has been developed specifically to accurately measure the performance of High Intensity Lighting on operational airfield runways and taxiways. It has been developed by Tailor Made Systems Ltd following an extensive research programme, commissioned by the UK Civil Aviation Authority / Ministry of Defence, into the performance of high intensity lighting under service conditions. MALMS has been designed to measure AGL system performance against the criteria for beam intensity and orientation defined in ICAO Annex 14, using the test methodology Annex 14 defines. It is accurate and repeatable and has been assessed by the UK Defence Evaluation and Research Agency on behalf of the Civil Aviation Authority. MALMS is therefore suitable to confirm compliance with National and International Standards. MALMS also produces routine reports and detailed graphical information for use by airfield engineering staff. This enables AGL systems to be kept up to standard with minimum resource allocation. The use of MALMS Differential Maintenance Strategy to target maintenance when and where required enables system performance to be improved without additional resources. This has been proven through extended trials on operational airfields in the UK. Issue: 10.2 September 2008 Page 8 of 50

10 Section 1 MALMS Photometric Measurement Systems Mobile Data Collection System The MALMS Mobile Data Collection System comprises: Trailer: The trailer is designed to mount sensor array in the required positions for measurement of both inset fittings (with / without toe-in) and elevated fittings (optional). The trailer has storage facilities to house sensor array(s) when in storage or transit and is equipped with full road lighting and can be supplied with optional warning indication for use airside. Light Sensor Array: The Light Sensor Array (LSA) is to facilitate the measurement of both sides of elevated fittings in a single run. The LSA comprises multiple Light Sensors and a Colour Sensor. The high accuracy light sensors include photopic response filters and are calibrated on a photometric bench against a NPL (UK National Physical Laboratory) photometer. The light meters each have 3 measurement ranges (with automatic range selection) and are designed to collect the illuminance data from which beam intensity is calculated. The colour sensor is used to confirm the colour coding of lighting and to check data validity. There are two such colour sensors fitted as standard. Position Sensor Array: An array of position sensors are positioned such that they can determine when the vehicle passes over a lamp and the offset of the sensor array (relative to the axis of the lamp) at this point. This information is used to determine the location each light sensor in the light beam during data collection and hence which data is used in the calculation of Average Beam Intensity. Power Supply: The sensor network is powered from a dedicated intelligent power supply unit. This unit takes 12V from the vehicle power supply or dedicated 12V battery. The power supply unit continuously monitors system operation and ambient external temperature. Issue: 10.2 September 2008 Page 10 of 50

11 Section 1 MALMS Photometric Measurement Systems GPS receiver: GPS (Global Positioning System) receiver determines vehicle position from the satellite radio navigation system developed by the US Department of Defence. The standard 12 channel receiver (non-differential) locates the position of the vehicle to within 100m and is used to determine which runway lighting section is being measured. The system is configured to accept differential correction factors when available which provide the added accuracy required to improve data verification and assist the location of specified fittings. Distance Transducer: The Distance Transducer is mounted on the wheel of the trailer and measures distance travelled to a resolution of 100mm. DR Positioning system: The high-precision sensor detecting changes in vehicle direction combined with data from the distance transducer it is used to calculate position and validate the course driven. Sensor network: A high speed communications network connects the sensors to the datalogger. The network provides reliable, high speed communications over the wide range of environment conditions such as those experienced on airfields and improves data quality and system reliability. Datalogger: A PC tablet compatible system for data collection and analysis. The data logger used Windows XP and is man portable with a built in GPS system allowing individual use for locating Unserviceable fixtures, without the need of the MALMS trailer. Operator Interface: A touch screen which enables the operator to select the lighting section to be monitored, control data collection and the analysis / transfer of data to the office PC. Test Facilities: Initiated either automatically or by the operator this takes the system through a detailed test sequence to confirm system operation prior to operation. The results of tests are automatically logged to enable subsequent analysis by TMS if required. Internal diagnostics: Advanced diagnostic routines enable remote support from TMS via modem link.

These are normally uni- / bi-directional fittings which are positioned in a line alone the direction of travel of the survey vehicle and whose main is orientated along the runway / taxiway. Before starting a survey run the operator should select the type of service from the list available. The system will then check the hardware configuration, if it matches that required for data collection on the specified service it will then check GPS position when the GPS fix matches that for a survey route the operator will be allowed to start a survey run. At the end of a survey run the quality of data collection is automatically assessed and the operator informed if a further survey run is required. Issue: 10.2 September 2008

26 Page 25 of 50 Section 3 MALMS Mobile Static Mode Enables photometric measurements to be taken with the Light Array (from the MALMS Mobile System) positioned statically in front of an AGL fitting. This can be utilised in 2 ways: o To test individual fittings that are included on a MALMS Mobile inspection courses useful for diagnostic work and when adjusting alignment o Test fittings on services (such as Threshold) which are off the paved area, or the beam is not on the axis of the runway and cannot be driven in the normal manner. Before starting a survey sequence the operator should select the type of service from the list available. The system will then check the GPS position and the operator can select the fitting location from the list of locations in the vicinity. Note: in Static Mode data collected is not subjected to the same automatic quality checks as with MALMS Mobile but the results are reviewed in the standard manner, both on the MALMS Data Logger and MALMS Office.
