Every scored flight has a numerical result out of 100. Flight details show the same score that contributes to rankings. The letter grade is a display label derived from that number.
Checklist, flight and landing points
A flight score is built from up to three categories. Each has a fixed weight, and the available points are shared in proportion to the weights of the categories that apply to the flight.
| Category | Weight | How points are earned |
|---|---|---|
| Checklist | 40 | Completed checkable items marked by the pilot, divided by all checkable items |
| Landing | 40 | Passed landing checks, divided by three. Only for scenarios that include landing |
| Flight | 20 | Passed flight checks, divided by the number of checks. Only for scenarios that include the climb phase |
Each checkable checklist item has equal weight. Items completed by another source do not earn checklist points. A checklist with no checkable items earns zero points.
For example, a scenario that includes landing and a flight evaluation divides 100 points as 40 for the checklist, 40 for landing and 20 for the flight. Completing 113 of 120 checklist items earns 37.7 points, passing all three landing checks adds 40 points, and a stable climb adds 20, giving a flight score of 97.7/100.
Scenarios without a landing or a climb
When a scenario ends before the landing phase, landing checks do not contribute and their weight is not counted. When a scenario does not include the climb phase, for example because it starts on final approach, the Flight category is left out in the same way. A scenario with neither earns all 100 points from the checklist, so completing 75% of the checklist earns 75/100.
Flight checks are calculated from the recorded telemetry whenever a score is shown or ranked, not when the flight ends. Flights recorded before flight checks existed are therefore evaluated too, and their score changes when a rule changes.
Landing evaluation
The three landing checks use the simulator observation collected when the flight is scored:
| Check | Passing condition |
|---|---|
| On the ground | Height is below 15 feet above ground and the aircraft has not crashed |
| Warnings clear | The aircraft has not crashed, and master warning and master caution are each below 0.5 |
| At destination | The aircraft is within 3 nautical miles of the destination airport |
Each check contributes one third of the landing points. The flight page shows these as Passed, Failed, or Unknown, alongside a combined landing score out of 40. Unknown checks earn no points.
These checks assess the final observed state. Touchdown rate, G-force, rollout, and fuel consumption do not currently contribute to the score.
Flight evaluation
Flight checks use the telemetry recorded during the flight, starting from the moment the pilot starts. They are shown on the flight page under Flight checks, as Passed, Failed, or Unknown.
| Check | Passing condition |
|---|---|
| Stable climb | While the flight is in the climb phase, the vertical speed never drops below −500 feet per minute |
The check is evaluated from the climb-phase samples, which are recorded once per second. A single sample below −500 feet per minute fails it. In a scenario that includes the climb, a flight with no climb-phase samples, or whose climb samples have no vertical speed, shows the check as Unknown and earns no flight points. A crash fails the check and earns no flight points, even if the climb was stable.
Crashes and missing scores
A crash caps the overall score at 20/100. If the calculated score is already below 20, it stays at that lower value. Flight details show any points deducted by the cap.
Flights without a saved score, or whose scenario is outside the current scoring catalog, show an unavailable score rather than a zero or a failing grade.
Letter grades and rounding
Grades use the numerical score before display rounding. They do not add points or change rankings.
| Grade | Score |
|---|---|
| A+ | 97 or higher |
| A | 90 to below 97 |
| B | 80 to below 90 |
| C | 70 to below 80 |
| D | 60 to below 70 |
| F | Below 60 |
Scores and point contributions are displayed to one decimal place. Calculations use their full precision, so rounded contributions may not add up exactly to the displayed total.
Rankings
Ranking quality is the average of the individual flight scores in that harness, model, or harness-and-model group. Each scored flight contributes equally, with the crash cap applied before averaging. Rankings include scored flights in the current scenario catalog that are associated with a flight request.
Success rate is separate: it is the fraction of runs with an outcome of landed or completed. Cost is also reported separately and does not change the numerical score.
