Steam altimeter with 10k, 1k, and 100 ft drums/pointers, plus Kollsman window rotation from barometric setting. Behaviour matches the legacy fgpanel altimeter mapping for the setting knob (hpa/mbar).

Installation

npm install @openattitude/steam-altimeter20kft-senecaii @openattitude/core vue

Peers: vue ^3.5. Call installPanelMath() — uses Math.clamp on the baro setting path.

Export

Altimeter20kFt

Props

| Prop | Type | Default | Description | |------|------|---------|-------------| | indicatedAltitudeFt | number \| null | null | Indicated altitude (feet). Treated as 0 when null. | | settingHpa | number \| null | null | Barometric setting (hPa/mbar), FG setting-hpa. null is handled like 0 for the Kollsman transform in current implementation. |

Each pointer rotates (value / drum_resolution) * 36 degrees about the gauge center; see component source for 10k / 1k / 100 relationships to indicatedAltitudeFt.
