Airbus A321 Joystick for Infinite Flight

The longest member of the A320 family was designed around a sidestick — so fly it with one. SkyYoke turns your iPhone into an A321 joystick for Infinite Flight, complete with a gated Airbus thrust lever, all over your own Wi-Fi.

An Airbus A321 joystick for Infinite Flight is a wireless controller that flies the simulator's A321 from a device you hold — and SkyYoke builds one out of your iPhone. Connect over Wi-Fi, tilt the phone like a sidestick or drag an on-screen joystick, and command roll, pitch, rudder and a gated Airbus thrust quadrant in real time, with no hardware to buy.

Stretch an A320 until the cabin seats roughly 220 and you get an airplane with its own temperament. The A321 is the heavy-lifter of its family — more passengers, higher operating weights, the jet an airline sends down its densest trunk routes — and flying it well in Infinite Flight means respecting that extra mass on every rotation and every flare. The right Airbus A321 joystick for Infinite Flight is the difference between wrestling the airplane and guiding it, which is why SkyYoke's answer is the device already in your pocket: an iPhone that becomes a wireless sidestick, gated thrust quadrant, rudder bar and control panel for the simulator running on your other screen.

SkyYoke turns an iPhone into a yoke, throttle and glass cockpit with live traffic radar for the Airbus A321
Your phone is the cockpit. A yoke, throttle and full glass cockpit on your iPhone — with live traffic radar.

There is a neat symmetry here. The real A321 is flown one-handed from a compact sidestick, small inputs with fly-by-wire doing the bookkeeping — and a phone held in one hand is very nearly the same gesture. Nothing to mount and nothing to pair: both devices join the same Wi-Fi, and SkyYoke discovers the simulator on the network by itself.

Within the A320 family, the A321 carries the longest fuselage, with room for up to about 220 passengers — the most of any of its siblings. Crews like it because the flight deck is the same sidestick fly-by-wire cockpit shared across the family; airlines like it because it hauls the biggest single-aisle loads on routes where every seat sells. Two wing-mounted turbofans move those higher operating weights, and the stretch shapes the airplane's manners: all that length behind the main gear means rotation deserves patience, and the extra weight keeps your energy planning honest on descent. In Infinite Flight's fleet those traits carry over, producing an airliner that rewards smooth, deliberate inputs — exactly the kind a well-tuned stick delivers. If you fly the whole lineup, the Real Airbus for Infinite Flight overview maps every model SkyYoke covers.

Your iPhone as an A321 joystick for Infinite Flight

  1. Hold & centreOne tap captures your grip as wings-level neutral.
  2. Tilt leftRoll the phone left and the aircraft banks left.
  3. Tilt rightRoll the other way to bank right — 1:1, smoothly.
  4. Tilt backEase the top toward you to pitch up and climb.

Pick the control style that matches how you sit. Motion Yoke reads the gravity vector against a neutral point you set, so your grip does not matter: the phone can lie flat on your lap or stand upright in your fist like a sidestick, and there is no gimbal lock in either pose. A configurable tilt range — anywhere from 15 to 60 degrees — decides how far you lean for full deflection, and a one-tap recenter captures a fresh neutral whenever you shift in your seat. Touch Joystick trades motion for a self-centering on-screen pad that tracks your thumb 1:1 and snaps back to center the moment you let go.

Talk to your copilot. Speak a natural command — like “landing gear up” — and the on-device AI flies it.

Whichever you choose, every axis runs through its own conditioning chain:

  • Sensitivity sets how much aircraft you get per degree of lean — dial it down for a heavy stretch.
  • Dead zone keeps a calm center without sacrificing full travel at the stops.
  • Expo curve softens the response around neutral while preserving authority at the edges — the closest a phone gets to Airbus stick feel.
  • Inversion, trim and smoothing fit the response to your hand and filter out jitter.

On an airplane this long, a touch of expo on the pitch axis is the difference between chasing the flight path and nudging it.

Thrust through the gates: the Airbus detent lever

AIRBUS DETENTS
TOGAFLX / MCTCLBIDLEREV
  1. TOGAFull takeoff / go-around thrust at the top gate.
  2. FLX / MCTReduced-thrust takeoff and maximum continuous.
  3. CLBThe climb detent — set it and leave it.
  4. IDLEBack to idle; every gate buzzes a haptic click.
  5. REVPull past idle for reverse thrust on the runway.

Airbus pilots do not slide thrust levers around — they snap them between detents. SkyYoke recreates that ritual automatically: select any Airbus type, the A321 included, and the throttle becomes a gated quadrant marked REV FULL / REV / IDLE / CLIMB / FLX·MCT / TOGA, with a haptic tick each time the lever crosses a gate. Set CLIMB by feel after departure; firewall to TOGA on a go-around without ever glancing down at your hand.

Underneath the gates, the smart-throttle safety logic keeps working for you. Pull into the red zone on the landing roll at 40 knots or faster and reverse thrust engages and is held on your behalf; below 40 knots the same travel becomes proportional wheel braking; in the air, reverse is blocked outright with a warning banner and a repeating haptic. The remote throttle page covers the lever in full.

Glass for the glass cockpit: instruments and aids

While you hand-fly the A321, SkyYoke keeps the essentials in front of you: live IAS, altitude, heading and vertical-speed chips, a ground/air phase chip, a spoiler annunciator, and Airbus-style PFD tapes — a speed tape with a trend arrow beside an altitude tape, both wearing cyan selected-value bugs like the real front office.

Two more aids earn their keep on a busy A321 sector. Arm the V-speed callouts from the Performance screen and the app speaks "V1", "Rotate" and "V2" during the takeoff roll, estimated from your weight and the density altitude — simulator figures only, never for real-world use. Meanwhile TCAS for Infinite Flight paints the multiplayer traffic around you, and the Violation Avoidance System watches Infinite Flight's 250-knot limit below 10,000 feet whenever the autopilot is flying — an aid, never a guarantee.

From gate to runway in five steps

  1. Join the same Wi-Fi. Your iPhone with SkyYoke and the device running Infinite Flight share one network.
  2. Enable Infinite Flight Connect in Infinite Flight's settings so the simulator accepts the link.
  3. Bind the axes once in Infinite Flight's Controllers settings — the in-app setup guide walks through roll, pitch, throttle and yaw.
  4. Load the A321 from Infinite Flight's fleet and spawn at the gate.
  5. Fly. The detented Airbus lever appears automatically; tilt or touch at 60 Hz, with a link watchdog that reconnects if your network blips.
Worth knowing: SkyYoke is an independent, unofficial app. Which aircraft exist in Infinite Flight's fleet, and what those aircraft can do, is determined entirely by Infinite Flight — SkyYoke controls what the simulator exposes. All V-speeds and performance figures are estimates for the simulator only.

Frequently asked questions

Flying the Airbus A321 in Infinite Flight with your iPhone as the joystick.

What is an Airbus A321 joystick for Infinite Flight?+

It is a controller that flies the A321 in Infinite Flight from a device you hold instead of the simulator's touchscreen. SkyYoke turns an iPhone into a wireless sidestick over your home Wi-Fi: tilt the phone or drag an on-screen joystick to bank and pitch, slide a gated Airbus thrust lever, and steer with a rudder bar — all sent to the simulator in real time, with no physical hardware.

Does SkyYoke give the A321 real Airbus thrust detents?+

Yes. When you fly an Airbus type such as the A321, SkyYoke automatically replaces the smooth throttle with a gated quadrant: REV FULL, REV, IDLE, CLIMB, FLX·MCT and TOGA. A haptic tick fires every time the lever crosses a gate, so you can set climb thrust after departure or push to TOGA on a go-around entirely by feel, without looking away from the simulator.

Should I fly the A321 with motion tilt or the touch joystick?+

Both are built in, and you can switch whenever you like. Motion Yoke reads gravity rather than raw angles, so it works with the phone flat on your lap or held upright like a sidestick, with a configurable 15–60 degree tilt range and one-tap recenter. Touch Joystick is a self-centering on-screen pad that maps 1:1 and springs back to neutral. A heavier jet like the A321 rewards a little expo on pitch for fine control.

Can SkyYoke help me avoid overspeed violations in the A321?+

It can help. The Violation Avoidance System watches Infinite Flight's 250-knot limit below 10,000 feet for Airbus and Boeing airliners while the autopilot is engaged. It arms roughly 2,000 feet above the band, then either clamps the autopilot speed target to 250 knots or manages energy during fast descents, with a colored annunciator and spoken alerts. It is an aid to your flying, never a guarantee.

Is SkyYoke an official Airbus or Infinite Flight product?+

No. SkyYoke is an independent iPhone app built on Infinite Flight's public Connect API. It is not affiliated with, sponsored by, or endorsed by Airbus or Infinite Flight LLC, and aircraft availability inside the simulator is decided entirely by Infinite Flight. The Airbus and A321 names appear here only to describe what the app is compatible with.
