Steam-style vertical speed indicator (VSI): needle rotation from a piecewise-linear ±2000 fpm calibration table; face is a prerendered SVG layer, needle is inline vector paths.

Installation

npm install @openattitude/steam-verticalspeedindicator-generic @openattitude/core vue

Peers: vue ^3.5.

Important: Call installPanelMath() once at application startup (import { installPanelMath } from '@openattitude/core'). The component uses Math.interpolate on the knot table.

Export

VerticalSpeedIndicator

Props

| Prop | Type | Description | |------|------|-------------| | verticalSpeedFpm | number \| null \| undefined | Vertical speed (ft/min). Treated as 0 when missing. |

Interpolation is defined internally for knots from −2000 to +2000 fpm; values outside the table clamp to the end angles.

Usage

<script setup lang="ts">
import { VerticalSpeedIndicator } from '@openattitude/steam-verticalspeedindicator-generic';
</script>

<template>
  <VerticalSpeedIndicator :vertical-speed-fpm="vsiFpm" />
