Runway Wheel HUD

📢 - INFO

The runway wheel HUD is the small set of circular buttons that pops up under a waypoint when you hover or tap it on the map. It lets you quickly adjust a waypoint's runway length and heading without opening any dialog.

When It Appears

• Hover a waypoint pin on the map (desktop) or tap it (phone).
• The HUD appears anchored to the waypoint, just below the marker.
• It disappears when you hover away for a moment or when you open another dialog (waypoint edit, share, etc.).

The Buttons

Button	Action
Ruler	Scroll wheel over it adjusts runway length — 10 m per click, 50 m with Shift held.
Compass	Scroll wheel over it adjusts runway heading (true) — 1° per click, 5° with Shift held.
Trending-up / Trending-down	Scroll wheel adjusts the required climb gradient — 0.5 % per click, 2.5 % with Shift held. Clamped 0 – 50 %. 0 hides the cones. Click to toggle the cone plot on or off without losing the gradient value: when cones are visible the icon is a sky-blue trending-up; when they are hidden it switches to a grey trending-down. Scrolling the gradient on a hidden waypoint automatically re-enables its cones.
Pencil	Open the full waypoint edit dialog.
Share	Share this waypoint (owner only).
Trash	Delete this waypoint, with confirmation (owner only).

Info Pill

Above the buttons, a small info pill shows:

• Runway length in your chosen unit (m or ft).
• Runway pair in standard aviation notation (e.g. RW12/RW30) based on the true heading plus local magnetic variation.
• Elevation — the terrain elevation at the waypoint coordinates.

If a runway is defined, a small amber line underneath shows the runway slope — the average absolute grade between the two runway thresholds, computed live from the 3D terrain heights sampled at each end (e.g. slope 1.25 %). It refreshes automatically as higher-resolution terrain tiles stream in when you zoom closer. The sign and which end is uphill are not displayed; the value is the magnitude only.

If a climb gradient is set, a further line shows it in your selected unit (percent or ft/NM). When the cones are toggled off via the climb-gradient button, that line is greyed out and struck through with (hidden) appended, so you can still see the stored gradient value. See the Tools menu for the gradient unit toggle (also mirrored in the mobile menu sheet).

If the waypoint has no runway info yet, the pill just shows elevation.

Approach & Escape-Path Cones

Setting a climb gradient draws two translucent sky-blue inverted cones on the 3D map — one with its apex at each end of the runway. The apex sits at ground level and the cone opens upward and outward at the chosen angle, so any terrain that pokes through the cone is an obstacle above your required climb path.

• Cones are circular, so they represent a required climb gradient in any direction from each runway end — handy for picking the best approach/departure bearing when terrain is asymmetric around the strip.
• The cone extends to ~450 m (1500 ft) above the terrain at the threshold; a shallower gradient makes the cone flatter and wider, a steeper gradient makes it narrower and taller.
• Requires a runway length > 0 — cones are anchored to the two runway endpoints, not to the waypoint center.
• Toggling visibility: click the gradient button on the wheel HUD to hide or show the cones for the current waypoint without changing the stored gradient. The setting is remembered per browser (not synced to the cloud or to users you shared the waypoint with), so shared viewers always see the cones until they hide them on their own device.

Owner vs Read-Only

If the waypoint was shared to you rather than owned by you:

• Length, heading, and climb-gradient wheels are locked — disabled and greyed out.
• The edit, share, and delete buttons are hidden.
• You can still see the info pill (including any climb gradient) and use the waypoint for the flight-path measure tool and for planning.

Setting a Runway From Scratch

1. Hover or tap a waypoint with no runway data yet.
2. Scroll the wheel over the ruler button a few times — the length climbs from 0 m up. As soon as a non-zero length is set, StolWRX initializes a zero-degree heading.
3. Scroll over the compass button to rotate the runway to the correct orientation. The live runway rectangle on the map updates in real time so you can align it with the visible strip on the satellite imagery.

Removing a Runway

Scroll the length down to 0 — StolWRX clears both the length and heading, returning the waypoint to a plain point.

Keyboard Tips

The wheel HUD is mouse/touch only. For precise values (e.g. a runway length from the FAA chart), use the Edit button to open the dialog and type the numbers directly.
