The ATC pre-departure delay is a proxy for ATC induced delays at the departure stand to avoid queuing at the departure runway.
The data is based on IATA delay code 89 [see (IATA 2012) ] which, besides delays caused by local ATC constraints, also includes delays due to late push-back approval and some other reasons which may introduce a certain level of bias. Work is in progress to allow for a better identification of the different causal factors.
