D-CAAE · Bombardier Learjet 45 flight activity
313 tracked flights in the 12 months to 31 Jul 2026, on about 14 days a month and an estimated 542 hours in the air.
How D-CAAE has been flying
D-CAAE flies about four and a half times as often as the middle Learjet 45, well above the 4 to 10 flights a month flown by the middle half of the fleet.
Tracked by ADS-B, so a minimum.
From time in the air. The logbook has the exact total.
Against 4.4 d for the middle Learjet 45.
Last tracked in July 2026. Published seven days later, by month only.
Month by month
313 flights over 10 active monthsFlights per month · shaded band is the middle half of the fleet (3.8–9.8 a month)
D-CAAE flew more than the middle half of the fleet in 9 of 12 months. Its busiest month was June 2026, with 76 flights.
Its busiest month was June 2026, with 76 flights. It did not fly in August 2025. The record has 153 tracking gaps, so about one flight in 2 may be missing and every count is a minimum.
Utilization
How steadily it has been used: flights, flying days and estimated hours against the type.
Flown far more than most. Harsher on utilization.
Heavy use means more of its maintenance intervals have been used up. Worth checking where it sits in its inspection cycle before a pre-buy.
Against 6.3 for the middle Learjet 45 (98th). Used harder than most.

The data behind it
Against all 480 tracked Learjet 45s, over its record since 1 Jan 2025.How it travels
Its flying is spread across many routes.
6 of 313 flights, both directions.
Spread across many destinations.
253 flights crossed a border.
D-CAAE’s flying is spread across many routes. Its most-flown pair of airports carries 2% of flights, 6 of 313, counting both directions. Its top three pairs make up 4%, so about ten flights in ten go somewhere else. Of its 313 tracked flights, 253 (90%) crossed a border.
Fatigue, corrosion, engines and brakes
01 Fatigue
Outside the middle of the fleetHow 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.
D-CAAE is out here, on one side or the other
Also graded: short hops. Leg length is shown as context. See this chapter in the sample report →
02 Corrosion
Close to the typeWhere 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.
D-CAAE is in here
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 typeHow 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.
D-CAAE is in here
Also graded: hot, high takeoffs; density altitude; dust and dry climate. See this chapter in the sample report →

It was last tracked in July 2026. We publish an aircraft’s flights seven days after they happen, and show them by month only.
Why don’t you show which airports D-CAAE uses?
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 D-CAAE?
All four graded chapters (Fatigue, Corrosion, Engines and brakes, and Utilization), each against the tracked Learjet 45s, 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.
How this page is made
Everything here comes from D-CAAE’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 Learjet 45s 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.
