Six hundred hectares of table-mounted string and a fleet of 3.6 MW machines, surveyed at the rate they were built: thermal across every string while the array is under load, an orbit around every blade, and the defects ranked before the O&M crew leaves the depot.
The sheet above is a drawing of this. 12 capture waypoints, and every finding called as the aircraft reaches it — scroll sets the target, the mission keeps its own pace, and the page waits for it.

SUN AND WIND, ON ONE RECORD.
One governed pass over a hybrid plant: a hundred and forty tracker tables read row by row at fifteen metres, the skids and the collector yard, then the unit walks under Array C and measures the twelve-kelvin anomaly the air pass flagged — and the tour climbs the ridge to take blade 03 tip-close and watch the third blade go up on the yoke.
A string drops out in March and nobody notices until the August reconciliation. From the access track, a failed diode and a clean panel look exactly alike.
Faults found under load
A heat pass flown while the array is generating separates them. Three strings in Array C came back at ΔT 12 K, located to the row and the table, on the record the same afternoon.
Leading-edge erosion is graded by whoever is on rope that week. Two technicians, two answers, and a repair schedule the asset manager does not trust.
One severity scale for 612 blades
Every blade is orbited at the same standoff and graded against the same structured template, so a category 3 on WTG 04 means what it means on WTG 41 — and the repair list sorts itself by severity, not by who wrote it up.

The array sits 140 km from the depot down a gravel track. A pilot, a truck and a day, for forty minutes of flying.
Nobody drives to the far site
A docked aircraft flies the array to schedule and the data is processed before the shift meeting. Twelve sites captured on the same morning with nobody on the road.

The program runs on the fleet's two clocks — the irradiance window over the arrays and the O&M calendar across the machines. Nothing on this list needs a rope, a truck or a curtailment; everything on it lands on the same record.

01
Dock flight
2×/day, processed before the shift meeting
A docked aircraft flies each array to schedule — including the one 140 km down the gravel track — and the data is on the record before the crew is assigned. All thirty-four sites captured to the same clock, with nobody on the road.

String heat pass
Each season, inside the irradiance window
The serpentine run is flown while the array is under load, because a failed diode and a clean panel look exactly alike de-energized. A fault comes back located to the row and the table, on the record the same afternoon.
Every blade is orbited at the same 42 m standoff and graded 1–5 against the same structured template, so a category 3 on WTG 04 means what it means on WTG 41 — and the repair list sorts itself by severity.

No — the opposite. The heat pass runs while the array is generating at 940 W/m², because a thermal fault only shows under load. The window opened at 11:40 and closed at 12:52: 44,000 strings scanned in 72 minutes of generation, none of it curtailed.
Can you really find one bad string in forty-four thousand?
Pass 3 came back at 12:06 with ΔT 12 K at row 14, tables 22–24 — three strings out in Array C, located to the row and the table. The trace ended at combiner 3C, and the swap was done before sunset the same day.
Who grades the blades — and do two techs give two answers?
The template does the grading. All 612 blades are orbited at the same standoff and graded 1–5 against the same structured template, so the leading-edge erosion on WTG 04's blade 03 carries the category it would carry on WTG 41. The repair schedule sorts by severity, not by who wrote it up.

Q04
Do we still send a crew 140 km down the track?
No. The dock flies the far array to schedule, twice a day with no pilot in a truck, and the data is processed before the shift meeting. What used to be a pilot, a truck and a day for forty minutes of flying is now nobody on the road.
2.4 cm detail from the 42 m orbit — sharp enough to grade leading-edge erosion with every technician on the ground. On the arrays, the heat pass resolves temperature differences of 0.1 °C.

Q06
Can one record hold the whole fleet, not one site?
Thirty-four sites and 1.2 GW on one record: 44,000 strings scanned each season, 612 blades graded on one scale, every defect ranked before a crew is dispatched. The asset manager and the O&M planner read the same ledger, cut to their own morning.

Q07
What does a buyer or a lender get when the plant changes hands?
The account of how it was actually built: every string, table, tracker and blade on file with the date it was placed and the state it was accepted in, graded on the one scale that runs across all thirty-four sites. Diligence reads the plant's own record instead of a folder of photographs taken by whoever had a phone.

Who reads it
Read overnight on a fleet like this one: the season's heat pass, the blade orbits, the fault ledger and the dispatch list at its current state. Three of the 27 profiles wake up to it.
Array C holds the morning: three strings out at ΔT 12 K, row 14, tables 22–24, and the trace ends at combiner 3C. Put the swap at the top of the board — the next irradiance window proves the fix.

Nobody goes on rope to grade a blade: all 612 were closed from the 42 m orbit, and the erosion on WTG 04's blade 03 was found, graded and scheduled with every technician on the ground.
