About this data

The additional ASMA time is a proxy for the average arrival runway queuing time on the inbound traffic flow, during congestion periods at airports.

It is the difference between the actual ASMA time of a flight and a statistically determined unimpeded ASMA time based on ASMA times in periods of low traffic demand.

When monitoring ASMA performance at airports, it is important to note that the goal is not to reduce ASMA time to the unimpeded reference time - as this could negatively impact on runway throughput - but rather to reduce additional ASMA time and associated fuel burnt to the necessary minimum.
