Flight Window
by sacdj
Flight Window lets players set how long the double-jump input stays open for toggling creative flight and opening an elytra glide.
What it does
The mod replaces the fixed double-jump timing in vanilla with an adjustable window. Vanilla uses a hardcoded 7-tick window, about 0.35 seconds, to toggle flight, and a double-tap that misses it does nothing, so the player falls instead of opening an elytra. A slider in the mod's menu sets a wider or narrower window, and the value is saved to options.txt like other vanilla settings.
Flight Window is client-side only, so a server does not need it and players on a server that does not run it are not flagged. The mod changes only input timing; it does not alter the flight or glide rules themselves. It is written for Fabric, Forge and NeoForge and requires Fabric API on Fabric. Files cover 1.20.1 – 26.2, with the latest Fabric build for 26.2, the latest Forge build for 1.20.6 and the latest NeoForge build for 26.2, all published 2026-07-19. The code is released under the MIT License and is not open source.
Key features
Adjustable double-jump window
A slider sets how long after the first jump a second press still counts, in place of the fixed vanilla timing.
Creative flight toggling
A wider window makes it easier to switch creative flight on and off with a double-tap of jump.
Elytra glide opening
The same double-tap that toggles flight can open an elytra glide, so falling players are less likely to drop.
Saved settings
Chosen values persist between sessions in options.txt, as other vanilla options do.
Compatibility

Use cases
Creative flight
Players flying long distances in creative mode can keep flight active without missing the second jump.
Elytra gliding
Survival players who double-tap jump to start a glide can use a longer window if the vanilla timing is too strict.
Who it’s for: Players who use creative flight or elytra and find the vanilla double-jump timing hard to hit. Because the mod runs only on the client, it suits single-player and multiplayer players alike.

What the author says
Ever try to drop out of creative flight to glide, and just... don't? You double-tap jump, nothing happens, you fall like a rock instead of opening your elytra. That's not lag — it's vanilla's hardcoded 7-tick (0.35s) double-jump window for toggling flight. Miss it and you either stay flying or fall with no elytra…
