Runway 26/08- runway strip width discrepancies in published Operational Data.
The AFAP believes that all pilots operating to and from Essendon Airport should be aware of this discrepancy.
Current operational data published for runway 26/08 at Melbourne’s Essendon Airport states the width of the runway strip (RWS) as 300 metres (or 150 metres each side of the runway centreline). This is the required RWS for a precision and non-precision approach for Code 3 or 4 runways.
Under the definitions of RWS published in CASR Part 139 Manual of Standards, any obstacles with in the RWS must be ‘of low mass and frangibly mounted’ in order to ensure minimal damage to an aeroplane in the event of a runway excursion.
ICAO Annex 14 provides a similar definition of RWS.
Currently to the south of the Essendon RWY 26/08 centreline there is a security fence, light poles, two very large steel water tanks and associated building approximately 112 metres from the centreline and the DFO building approximately 130 metres from the centreline.
As these structures are neither of low mass nor frangibly mounted they effectively reduce the actual RWS to approximately 230 metres rather than the 300 metres published.
CASA, Airservices and the ATSB were notified of our concerns in November 2017.
