Streamlining NASA Task Load Index for Simulated Fighter Missions

Key Points

The research aims to enhance the NASA-TLX by simplifying its dimensions for evaluating workload in fighter pilot simulations.
Evaluated the NASA-TLX dimensions for relevance in simulated fighter missions.
Focused on omitting the physical demand dimension.
Tested the validity of a three-dimensional approach (mental, temporal, frustration).
Omitting the physical demand dimension did not significantly impact validity.
Using three dimensions reduces pilot burden in training contexts.
Streamlined assessment supports efficient workload evaluation.

Abstract

The findings indicate that the NASA-TLX can be streamlined for simulated fighter missions by omitting the physical demand dimension and, when brevity is essential, by using three dimensions (mental, temporal, frustration) without substantial loss of validity. This approach reduces pilot burden and simplifies administration, supporting efficient MWL assessment in training contexts. Mansikka H, Virtanen K.
