The research behind the horizon.
From the first 100-route notebook to the Round 22 airport evidence programme. Neither a nominal range chart nor a preliminary runway record proves the feasibility of a flight.
Current research questions
2016–2025 upper-air wind cases: 0. Validated IFR trajectories in both directions: 0. OEM fuel/performance mission datasets: 0. Aircraft/operator route permissions: 0. All routes remain preliminary research—not approved operations or bookable flights.
What changed in Round 22
14 national-AIP updates in Round 22, increasing records with physical runway length to 74 of 188. Directional TORA and LDA, rescue and firefighting provision, handling, permissions, meteorology, safety and airspace still require route-by-route verification.
Source lineage
The original 100-route snapshot remains unchanged and checksum-pinned. Round 22 is imported from its separately hashed 188-row source file. The updated Bishkek airport code BSZ replaces FRU for current display while the historical code is retained as an alias.
