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.
