SUBSECRETARIA ADJ. DE OPERACOES AEREAS

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/18, Dec/18, Jan/19, Feb/19, Mar/19, Apr/19, Jun/19, Jul/19, Sep/19, Oct/19, Nov/19, Jan/20, May/20, Jun/20, Jul/20, Sep/20, Jul/21, Aug/21, Sep/21, Dec/21, Jan/22, Feb/22, Mar/22, Apr/22, Jun/22, Aug/22, Sep/22, Oct/22, Nov/22, Dec/22, Jan/23, Feb/23, Mar/23, Apr/23, May/23, Jun/23, Jul/23, Aug/23, Sep/23, Oct/23, Dec/23, Dec/25, Jan/26, Feb/26, Mar/26, Apr/26, May/26, Jun/26, Jul 16, 26); 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 CNPJ comes from name continuity on the same registration and, where that is not enough, from the company name when it resolves to a single CNPJ in our records (tax registry and current registration). Ambiguous names or vanished companies are left out.
