Done in v0.30.0 (PR #61, merge commit 57cc670, deployed to https://flight.dev.kkhost.pl).

What changed:

  • Landing no longer pauses the sim — it now slows time down to 1× whenever a plane lands while any plane is on the ground (lib/sim/engine.ts tickOnce; chained planes that immediately start their next queued leg stay airborne and don't trigger the slowdown).
  • New persisted column sim_state.last_selected_time_scale (guarded ALTER + one-shot backfill from the current scale for existing installs) remembers your last manually selected speed.
  • When a dispatch takes the last grounded plane airborne, the sim resumes that last selected speed automatically (flyPlane).
  • Manually changing the speed updates the resume target (last intent wins — this is the "unless changed manually" rule; no extra flag needed). Pause remains a manual-only control and is untouched by landings.

No client changes required — the slider/label re-read timeScale from each poll, so the slowdown and resume are visible automatically. Tests: engine/actions/sim-route unit suites rewritten for the new semantics, legacy-DB backfill covered in the migration test, and e2e/pause-on-landing.spec.ts renamed to e2e/slow-on-landing.spec.ts asserting slow-to-1× on landing + resume of the last selected speed on dispatch.

Done in **v0.30.0** (PR #61, merge commit `57cc670`, deployed to https://flight.dev.kkhost.pl). What changed: - Landing no longer pauses the sim — it now **slows time down to 1×** whenever a plane lands while any plane is on the ground (`lib/sim/engine.ts` tickOnce; chained planes that immediately start their next queued leg stay airborne and don't trigger the slowdown). - New persisted column `sim_state.last_selected_time_scale` (guarded ALTER + one-shot backfill from the current scale for existing installs) remembers your last manually selected speed. - When a dispatch takes the **last grounded plane** airborne, the sim resumes that last selected speed automatically (`flyPlane`). - Manually changing the speed updates the resume target (last intent wins — this is the "unless changed manually" rule; no extra flag needed). Pause remains a manual-only control and is untouched by landings. No client changes required — the slider/label re-read `timeScale` from each poll, so the slowdown and resume are visible automatically. Tests: engine/actions/sim-route unit suites rewritten for the new semantics, legacy-DB backfill covered in the migration test, and `e2e/pause-on-landing.spec.ts` renamed to `e2e/slow-on-landing.spec.ts` asserting slow-to-1× on landing + resume of the last selected speed on dispatch.
