THE RULES BEHIND EVERY FLIGHT

HOW IT SCORES.

By Matt Scobel, developer of Vector Tango · Updated

In Vector Tango you draw a line from each plane, and the plane flies it. The game judges every flight, and the results give your star rating. Each figure below plays on a loop. Swipe across it to try the rule yourself, or focus it and use the arrow keys. Press Space to pause.

The basics

A plane flies the line you draw, but only as its physics allow: no turn is tighter than its turn radius. Match the aircraft’s assigned colour to its runway or pad: RED, BLUE or YELLOW. Arrivals land, departures leave, and overflights cross to an assigned exit. A circuit must pass its marked rings before landing or leaving. Pass the wide hoop and then the small threshold hoop in order. Cutting into the cone from the side does not complete an approach. An outbound flight leaves through its assigned handoff area. Each landing and each correct exit is one safe flight. In Competitive your score is your safe flights, and only a crash ends the run.

Route efficiency

Route efficiency compares your controllable flight time with the game’s estimated efficient route, including any required circuit rings. The allowance is that estimate, at least 1 second, plus 2 seconds. Stay within the allowance for 100 %. Beyond it, efficiency is 100 × allowance ÷ actual time, rounded to a whole percent. Automatic taxi and takeoff time is added to both sides. Leaving a ready departure waiting when its runway is clear adds only to your time. Airborne planes keep flying while you draw. The diagram pauses them during drawing so you can compare the routes.

Landing accuracy

Accuracy is measured when the game captures the aircraft for automatic landing, near the small threshold hoop. The game compares its distance from the centre line with the radius of the small hoop at the runway. Inside the green ring, 0.2 of that radius, is 100 %. The white ring, half of it, is 90 %. The red ring, the full radius, or more is 50 %. These coloured rings explain the measurement. Emergency and planned low-fuel landings do not contribute an accuracy sample.

Near misses

Two airborne aircraft that come too close inside controlled airspace make a near miss. The gold ring shows that distance, which is 1.8 times the crash distance shown by the white ring. Inside the white ring the planes crash. A pair counts once per encounter and must separate beyond 1.15 times the warning distance before another near miss can count. Ground collisions and scenery can also end a run. A crash ends Competitive and fails a Campaign shift.

Missed handoffs

On a tabletop airport, each outbound flight has an assigned handoff area: one bay of the wall, 26° wide and one level high. The jet here must leave through 030/3, lit on the wall. A correct outward crossing is accepted from 92 % of the wall radius. Leaving through the wrong area is a missed handoff, not a safe flight. The aircraft blinks green for a correct exit or red for a miss. In room-scale play, handoffs use the marked room portals instead of this circular grid.

How it all comes together

The rating calculation starts at five stars. Four things can each cost up to one star. Route efficiency and landing accuracy are averaged over the run: 90 % and up costs nothing, 70 to 89 % costs half a star, and under 70 % costs one star. Near misses and missed handoffs each cost half a star per 10 resolved flights. Resolved flights means safe flights plus missed handoffs, with a minimum of 10 for the calculation. The total rounds to the nearest half star, with a minimum rating of one star. Redrawing a route has no direct penalty. Campaign uses this rating only for a passed shift. A failed Campaign shift gets zero. Competitive still rates the safe flights completed before a crash, but a run with no safe flights gets zero. Try it.

The calculator shows the rating for a passed Campaign shift or a Competitive run with at least one safe flight.

In the Campaign, each shift keeps your best rating. In Competitive, the stars show how cleanly you flew, and the leaderboard ranks runs by safe flights. For what a shift feels like and what is real about air traffic control, read How it plays.

Vector Tango is a mixed reality air traffic control game for the Meta Quest, coming to the Meta Horizon Store in October 2026. Wishlist it on Meta Quest and follow the Flight Log for release updates.

Checked against Beta 37.1015.1803. The diagrams illustrate the scoring rules on a simplified airport. Routes, timing and aircraft are examples, not a full physics simulation. Actual aircraft have different turn and climb limits. Planes are drawn larger than their collision size so you can see them.
