CDU Remote — Boeing 737-800 IDENT page

Built for solo virtual pilots

Anyone who flies the 737 from home and wants a real CDU experience without buying hardware.

Tablet pilots

Mount an iPad or any touchscreen next to your monitor. Tap LSKs and clear messages without leaving the cockpit view.

Budget cockpit builders

A hardware CDU costs $1,500–$3,000. CDU Remote runs on the second-hand tablet you already own.

Long-haul SimPilots

Punch in waypoints from the couch, monitor PROG pages while your pizza arrives. The view in your sim stays clean.

How it works

Three steps. Most pilots are flying within five minutes.

  1. 1

    Enable X-Plane Web API

    Inside X-Plane 12, enable the built-in Web API (it's already there — no plugin to install).

  2. 2

    Open CDU Remote

    Sign in on aerosim.ca, launch CDU Remote, point it at your sim's IP. The browser connects via WebSocket on port 8086.

  3. 3

    Fly

    Type, tap LSKs, watch the CDU display update in real time. Every keystroke goes straight to the Zibo's FMC.

What's under the hood

Built like a real CDU — pixel coordinates, hitboxes, datarefs.

Pixel-perfect bezel

Every key, LED and screen pixel matches the Zibo CDU. Hitboxes scale with your screen so taps land where they should.

Real-time WebSocket

Direct WebSocket to X-Plane v3 API. Push updates instead of polling — no input lag.

86 datarefs wired

All LSKs (6 left + 6 right), the full alpha-numeric keypad, EXEC, MENU, NEXT PAGE, PREV PAGE, and the LED indicators (MSG, OFST, FAIL, EXEC).

Responsive

Phone, tablet, ultrawide. The CDU centers itself and keeps its proportions on every form factor.

Saved layouts

Your preferred IP, scale, and position are stored in your account — no re-typing on each session.

Same-network setup

No tunnel, no port-forward. Your tablet and your sim talk directly over your home Wi-Fi.

Your sim data never reaches our servers

  • The CDU connects directly from your browser to your X-Plane on your home network.
  • Position, altitude, speed, FMC inputs — none of it is logged or transmitted to aerosim.ca.
  • We only store your account, your saved layouts and the auth token your browser uses to log in.
