ACTION TO BE TAKEN WHEN FLIGHT INSPECTION INTERVAL HAS BEEN EXCEEDED If an inspection is not conducted at the appropriate time, different types of action can be considered: Due date is extended after engineering evaluation and/or ground maintenanc e reinforcem ent Degrading of the category of ILS (Cat III down to Cat I). This could be a solution in the counties where intervals vary according to the category of ILS The navigation aid is removed from service In France if the flight inspection interval and due date window is exceeded a commissioning

inspection is required to return the navigation aid into service. Removing an operational navigation aid from service may appear to be a drastic measure; however there comes a point where its continued use can no longer be justified in terms of safety. It is essential that airport authorities are aware of the consequences of postponing flight inspections. CONCLUSIONS Doc 8071[1] provides guidance for setting a flight inspection interval. Where possible in this paper, further depth has been added to the Doc 8071[1] guidance to assist in the selection of an appropriate flight inspection interval for a particular navigation aid. No formula exists to determine the correct flight inspection interval; therefore engineering judgement plays an important role. Engineering judgement should take into account all the relevant information pertaining to the navigation aid. Whilst Doc 8071 [1] does not include a due date window many states have chosen to adopt this concept. This window should be considered as part of the overall flight inspection interval and should not be so long as to significantly increase the risk of the signal in space drifting out of tolerance. A review of the ICASC member states identified that the majority of these states use a 180 day flight inspection interval as specified in the schedules of Doc 8701 [1]. France, after a thorough case study determined that they had sufficient policy and historical data to extend the flight inspection interval to 360-days. RECOMMENDAT IONS The following recommendations are made for the benefit of organisations setting flight inspection intervals. Recommendation one. The organisation should have a clear documented policy and process for determining and recording the flight inspection interval. Recommendation two. The organisation should have robust safeguarding procedures to protect the navigation aid signals from unwanted reflections. Recommendation three Visual inspection of the local environment should conducted by trained engineers to prevent reflecting object inadvertently encroaching close to the navigation aid. FUTURE WORK More specific guidance with practical examples will be prepared to assist organisations assessing flight inspection interval.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
