Utilization

Typical than the type

How steadily it has been used: flights, flying days and estimated hours against the type.

Used about as much as most. Typical on utilization.

Used at about the rate of most of the fleet, so its maintenance intervals have been used up at a normal pace.

Flights a monthTypical
4.9

Against 6.6 for the middle Praetor 600 (35th). Used like a typical Embraer Praetor 600.

N640AF’s flying is spread across many routes. Its most-flown pair of airports carries 9% of flights, 5 of 54, counting both directions. Its top three pairs make up 26%, so about seven flights in ten go somewhere else. Of its 54 tracked flights, 3 (6%) crossed a border.

Chapters 01–03

Fatigue, corrosion, engines and brakes

01 Fatigue

Outside the middle of the fleet

How short were its legs? Airframes age by landings as well as by hours. Many short legs put more pressurization cycles on the structure for the same time in the air.

Hours per landing Lead metric

02 Corrosion

Not graded: not enough data

Where does it spend its nights? Where a jet sleeps shapes how fast it corrodes. Salt and damp overnight are what an inspector looks at first.

Salt air Lead metric

Also graded: damp air, freeze–thaw, near the coast and moisture in the air. See this chapter in the sample report →

03 Engines and brakes

Close to the type

How hard were its airfields? Short, hot and high runways ask for more thrust on every takeoff and harder braking on every landing. That wear doesn’t show in the hours.

Short runways Lead metric
Departures where the longest runway was under 1.25× the takeoff distance

We leave out airports, bases and exact dates on purpose. We show how an aircraft has been used, not where it goes.

What’s in the full TailCheck report for N640AF?

All four graded chapters (Fatigue, Corrosion, Engines and brakes, and Utilization), each against the tracked Praetor 600s, plus the operational summary and operating rhythm, as a PDF, CSV and share link. It costs $395, or $995 a month for unlimited reports and Spotlight.

Method

How this page is made

Everything here comes from N640AF’s ADS-B track, the position signal aircraft broadcast, over the 12 months to 31 Jul 2026. ADS-B misses some flights, so every count is a minimum. Flights appear seven days after they happen, by month only, and hours are estimated from time in the air; the logbook has the real totals. Airports, bases and exact dates are left out on purpose. How grades work: each graded measure is placed among the tracked Praetor 600s against the middle aircraft, the 50th percentile. Between the 25th and 75th it is typical; outside that band it is gentler or harsher. Utilization is graded here for free; for the other chapters this page shows the middle value of the fleet and whether this aircraft sits inside the middle half or outside it. Their grades and values are in the report, not on this page. Owners and operators can ask us not to publish an aircraft’s activity.
