PLI - Peak Load Index

The Peak Load Index (PLI) and the Basic Load Index (BLI) were defined as indicators that enable to compare airport capacity utilisation.

Schinwald/Hornung (2014) describe a procedure to quantify the level of capacity utilisation comparing two characteristic throughput values. The PLI is a measure for the time the airport operates traffic peaks. The BLI measures how much of the available capacity is used across the majority of the operating conditions.
