The free chapter.

Each measure against all 620 tracked GIVs. Every dot is one aircraft; the gold one is 4K-LAR.

Chapter 1

Fatigue

Typical for its type

How short were its legs?

Utilization isn’t graded for 4K-LAR: too few of its flights were tracked to count its use fairly, in the full report too. So its free chapter here is Fatigue, which doesn’t depend on catching every flight.

It lands about as often for its hours as most of the fleet, so cycles have built up at a normal pace.

Harsher means harder on the aircraft than three quarters of GIVs; typical is the middle half. Percentiles compare this aircraft with every tracked GIV, over its record since 1 Jan 2025.
