The free chapter.

Each measure against all 836 tracked Challenger 300s. Every dot is one aircraft; the gold one is N357CZ.

Chapter 1

Fatigue

Gentler than its type

How short were its legs?

Utilization isn’t graded for N357CZ: 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.

More hours for each landing, so fewer pressurization cycles for its time in the air.
