Additional ASMA Time

The Additional ASMA time is the difference between the actual ASMA transit time and the unimpeded ASMA time calculated for non-congested conditions.

Unit of Measurement

Minute.

Calculation of the indicator

Let

The additional ASMA time, , is calculated for each flight f(c) as the difference between the actual ASMA transit time AcASMA(f(c)) of the flight and the unimpeded ASMA time UASMA(c):

The additional ASMA time, , for a given combination is the average of the additional ASMA time, of all the flight characterised by that combination .

The additional ASMA time, , for a given airport is the weighted average of the additional ASMA time, , for all the combinations at that airport with their probability of occurrence.
