TMS has developed a unique understanding of the factors that should be closely monitored to ensure that performance meets ICAO standards. Based on this TMS can offer a Performance Audit service that can reduce the risk of an installation failing to meet the required performance standards - normally accepted to by 50% of the ICAO standard - during operation. The service is based around TMS's MALMS Mobile technology, and provides for TMS staff to undertake a complete audit of an airport's AGL system. This will include a detailed audit report, highlighting overall system performance, any specific fitting failures or general problems, priority repair work and maintenance requirements. This service can be implemented as part of / prior to the supply of a MALMS Mobile system, or it can be an independent contract to provide an airport with regular audits at agreed intervals, so enabling the establishment of effective maintenance and repair programmes. TMS Photometrics implements a policy of strict data confidentiality. Information and results are only supplied to the airport authority concerned unless specific authority has been granted to allow its release to a third party (such as the relevant Civil Aviation Authority).
