C172-style flaps lever

The 172's flap lever on its black plate: drag the white handle through its gated slot to a detent and the simulator's flaps follow. A white pointer shows where the flaps really are, beside a speed placard from the aircraft profile.

Features
- Gated slot that steps over at each notch past the first; detents at the 172's spacing (3 positions), else even
- Click and haptic tap at each detent while dragging
- White pointer in its own slot showing the real flap position as it moves
- Scale 0, 10, 20, 30 degrees (40 degrees full for more than three positions)
- Speed placard: blue band with the first-notch limit (Vfe1) and white with the full-flap limit (Vfe), in KIAS, from the profile (numbers left out on a generic profile)
- WING FLAPS lettering; plate and lever lit by the red flood at night; the glareshield's warm light falls on the faceplate too when its dimmer is up (Settings > Dimmers > Glareshield, off by default)
Your aircraft: Number of detents from the simulator's flap positions; placard speeds (Vfe1, Vfe) from the profile's V-speeds (blue band hidden if Vfe1 is unknown). A generic profile (speeds not known) leaves the placard's numbers out.
On the iPad
- Drag the handle up or down along its slot; release at a detent to send the flaps there
- Long press to change or move the module

Simulator data
What the Hub reads from the simulator for this instrument, and what the instrument sends back. Names are the simulators' own: MSFS SimVars and events, X-Plane datarefs and commands.
Reads
| Value | MSFS | X-Plane |
|---|---|---|
| Flap handle position, 0 = up (index) | FLAPS HANDLE INDEX (number) | sim/cockpit2/controls/flap_handle_deploy_ratiosim/aircraft/controls/acf_flap_detents |
| Number of flap handle positions (count) | FLAPS NUM HANDLE POSITIONS (number) | sim/aircraft/controls/acf_flap_detents |

| Releasing the handle at a new detent (the difference in positions), or mapped 'Flaps +' / 'Flaps -' | FLAPS_SET | sim/cockpit2/controls/flap_ratio |
Add-on aircraft with their own systems may use other variables; the Hub reads the standard ones.
Changes
The instrument's version counts what its faces share (the case, the mechanism, the data, the sounds); a face's own version counts that face alone.
