HERGEN S.A. MÁQUINAS E EQUIPAMENTOS

Showing 8 of 112 snapshots (the first plus the most recent); the chart and the Δ consider all of them.

Peaked at 3 aircraft (Nov/24, Dec/24, Jan/25, Feb/25, Mar/25, Apr/25, May/25, Jul/25, Aug/25); the latest snapshot shows 2. The endpoint delta alone would not show the peak.

One aircraft came and went between the endpoints: it only shows up because we look at every snapshot, not just the first and the last.

Comparison across the RAB snapshots we hold. Between two snapshots there is no reading: the change may have happened at any point in the window, and the aircraft may have passed through other operators along the way.

The 80 snapshots before Sep/24 come from ANAC's monthly file without the engine column: reserved marks are under-detected in that stretch, and at the Sep/24 seam an aircraft that starts showing as reserved may just be detection kicking in, not a change in the RAB. Every attribution starts from the CNPJ reported by ANAC. From May/18 to Dec/21 ANAC masked every document: in those snapshots the same registration inherits the CNPJ proven in neighbouring snapshots as long as the set of names does not change; anyone who entered and left entirely within that window is left out.
