as <strong>the</strong> number of passenger hours saved (<strong>the</strong> product of <strong>the</strong> number of avoided diversions (% of<br />

total flights), <strong>the</strong> average passenger load (%), and <strong>the</strong> average outbound passenger waste time<br />

per diversion (mins)), monetised using CASA published estimates of passenger VoTT.<br />

Average outbound passenger waste time is calculated as <strong>the</strong> average time from scheduled<br />

departure to actual departure during bad wea<strong>the</strong>r events at SCA (in total, one hour per out-bound<br />

passenger per diversion).<br />

Growth rates are a function of a 1% real growth rate in VoTT (to reflect expected real wages<br />

growth over time) and <strong>for</strong>ecast growth in aircraft movements (and <strong>the</strong>re<strong>for</strong>e growth in <strong>the</strong> number<br />

of diversions avoided compared to <strong>the</strong> base case).<br />

This benefit category represents <strong>the</strong> reduction in travel time <strong>for</strong> passengers within <strong>the</strong> SCA<br />

catchment area who would, but <strong>for</strong> <strong>the</strong> introduction of new routes at SCA, o<strong>the</strong>rwise arrive/depart<br />

at/from Brisbane <strong>airport</strong>. It is a function of <strong>the</strong> total number of flights on new routes (including both<br />

international and domestic), average passenger load, and <strong>the</strong> average time taken to travel to<br />

Brisbane <strong>airport</strong> to arrive at <strong>the</strong> total passenger time now avoided by <strong>the</strong> implementation of <strong>the</strong><br />

new runway. CASAs published passenger VoTT per hour is applied to quantify <strong>the</strong> total value of<br />

time avoided.<br />

Growth in benefits is derived from a 1% increase in VoTT over time and <strong>the</strong> incremental growth in<br />

<strong>the</strong> number of new services at SCA.<br />
