Initialization

At first, you need to assign avionics.js to html element:

var avionics = new Avionics(nodeElement);

After initialization, you can set values:

avionics.pitch = 10;

API

Here is the list of available setter-methods:

Available setter-methods
airspeed
altitude
roll

// You can run it in browser console to see current available methods
Object.getOwnPropertyNames(avionics.__proto__).filter(i => !i.startsWith('_') && i !== 'constructor')

Roll

Roll value of the aircraft, deg. Increase roll value to proceed counter clockwise rotation, negative for clockwise. Acceptable values from -180 to 180 deg. Setter name: roll.

Pitch

Pitch values of the aircraft, def. Nose up is for upper semisphere, down for lower. Acceptable values from -180 to 180 deg. Setter name: roll.

Airspeed

Indicates airspeed, knots, m/h or km/h. Can show values from 0 to 500. Setter name: airspeed.

Altitude

Shows altitude, feet or m. Can show values from -10000 to 10000 (but scale only starts from 0). Values below zero is possible with different settings of qnh. Setter name: altitude.

Vertical speed (VSI)

Gives rate information for the climb or descent, m/s. Usually in the range −30 to +30 m/s (-6000 to +6000 fpm). Setter name: verticalSpeed.

Heading

Shows heading of the aircraft, similar to a magnetic compass, deg. North direction corresponds to zero angle. Setter name: heading.

Ground speed

Indicates ground speed, knots, m/h or km/h. Can show values from 0 to 500 (why???). Setter name: groundSpeed.

Selected altitude

Shows selected altitude, feet or m. Can show values from -10000 to 10000 (but scale only starts from 0). Values below zero is possible with different settings of qnh. Setter name: selected Altitude.

QNH

Shows QNH: the pressure measured at station then reduced down to mean sea level pressure; mmHg, inHg, hPA. Can show values from -900 to 1200 (hPa). Setter name: qnh.
