This is due to the large range of different approach speeds that IDO encompasses. Such a development will present a challenge for airports, which are already operating at or near their capacity limit. An alternative routing towards an intercept point at a late stage of the final approach can provide two approach options with relatively low interference for subsequent traffic. With the help of recorded traffic data from London Heathrow, this study evaluates the performance in terms of capacity for different constellations of this procedure. Moreover, the biphasic evaluation, conducted through theoretical calculations for a constant separation distance and a fast-time simulation for a constant separation time, yielded key findings that facilitated the development of an optimized procedure for a traffic mix with significant speed differences to compensate IDO-related capacity losses as far as possible. air transport system efficiency approach procedure time-based separation increasing diverse operations final approach Full Text Additional Declarations No competing interests reported.
