The free chapter.

Each measure against all 353 tracked Citation SIIs. Every dot is one aircraft; the gold one is N721GK.

Chapter 1

Fatigue

Typical for its type

How short were its legs?

Utilization isn’t graded for N721GK: 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.
