Hold Simulator

Read the clearance, fly the entry, complete one lap of the racetrack. Autopilot via two rotary dials — no window view, just instruments like real IFR.

How to fly it — controls & tips

You get a clearance and an instrument panel — no outside view, like real IFR. Work out the entry, fly it on the dials, then fly the racetrack. One lap by default.

The two dials

Spin
Drag around the knob like a real bezel, or scroll the wheel over it. Flick it to move fast.
Type a value
Double-click the number in the middle.
Long-press CRS
Hold it for half a second and the course snaps to your bearing to the fix — the needle centres and you're pointed direct. The quickest way to get established when you've drifted.
Long-press HDG
Syncs the bug to the heading you're already flying, so switching to HDG mode doesn't start a turn.

Modes

HDG
Flies the heading bug. Use it for the entry turns and the outbound leg.
CRS
Intercepts and tracks the course you've dialled, correcting for wind. Use it for the inbound leg — it will cut across at up to 45° and roll out on the centreline.
AP ON / OFF
Off is wings level. The aeroplane keeps flying; it just stops turning.

Timing

STOPWATCH
Click to start, again to stop, again to reset. Start it wings-level outbound — that's where the one minute is measured from, not from over the fix.
T+
Time since the scenario started.
REMAIN
Hard stop for the scenario. It's four minutes until you reach the fix, then opens up to fit the entry and the laps your clearance calls for.
1× / 2× / 4×
Time multiplier. Worth using on a five-mile leg.
⏩
Hold for 8×. Let go and you're back to normal.

Reading the HSI

Needle & CDI
Deviation from the dialled course, in degrees like a real VOR. It swings hard and reverses as you pass overhead — that's the cone of confusion, not a glitch.
Magenta diamond
Your ground track. With wind, that's where you're actually going, as opposed to where the nose points.
DIST & pointer
Distance and bearing to the fix. Both the diamond and this can be switched off in settings if you want it harder.

How it's scored

Entry flown
The tool works out which entry you actually flew from your track, and marks it against the one the clearance called for.
Course tracking
Only on the inbound leg. The outbound leg is offset by design, so flying it properly costs nothing.
Leg timing
Against the legs in your clearance — one minute, or four or five miles. Timed from the start of the racetrack, so the entry itself isn't held against you.
Completion
Ending early, or running out of time, costs you. The verdict tells you which.

Worth knowing

  • Fly the entry in HDG, then switch to CRS once you're turning back toward the inbound course.
  • The map is hidden on purpose — instruments only is the realistic mode. It's there when you need it, and your results note whether you used it.
  • Wind is off by default. Turn it up once the geometry is automatic; that's when the outbound timing and drift get interesting.
  • Found something wrong? The 🐛 button attaches the scenario, your flight path and a debug log, so it can be replayed exactly.

Tip: the map view (top-down) is hidden by default — flying on instruments alone is the realistic mode. Show the map only as a training aid when you need it.
