ACROWRX - Judge View

📢 - INFO

This page provides detailed information about how to use the Judge view in ACROWRX.

Judge View

Probably the most important feature of ACROWRX is the Judge View. The Judge View allows you to visualize your flight from the Judge perspective, without the need for a person sitting on the ground, critiquing or filming you. There are some useful features to learn about the Judge View.

On-Screen Button Cluster

On the right side of the Judge View, a vertical button cluster provides quick access to the most common toggles without needing keyboard shortcuts:

• Axis toggle — show or hide the reference axis (same as X key)
• Box toggle — show or hide the aerobatic box (same as B key)
• Free-look toggle — enable or disable manual judge head movement (same as H key)
• Additional info toggle — show or hide the telemetry HUD overlay (same as I key)
• Flight controls toggle — show or hide the stick position display (same as K key)
• Clear markers — remove all dropped markers (same as C key)

When a video is loaded, two additional buttons appear:

• Mark sync frame — marks the current data position for video synchronization (same as V key)
• Sync video — synchronizes the video to the current position using the marked frame (same as Ctrl+V)

Judge Head Control

The Judge head position is, by default, always pointing at the aircraft - like a perfect camera that tracks the airplane all the time. To control the zoom, you can use the scroll wheel on your mouse or a pinch gesture on Mac computers. A vertical FoV slider on the side of the Judge View also allows you to adjust the field of view.

Using the keyboard key H, you can set the Judge head position manually, using your mouse to click and drag. This is especially useful to have an overall view of a maneuver, such as how round a loop is. The on-screen button cluster on the right side of the Judge View also has a toggle for this free-look mode.

Airplane Trajectory

In the Judge View, the airplane displays a short trailing trajectory line. Think of this trajectory line as a smoke trace. The length of this trailing line can be adjusted using the vertical Trace Size slider on the side of the view.

Using the keyboard key Z, you can toggle the display of the full trajectory from the beginning of the flight. This persistent trajectory is useful for checking the consistency of arcs and the position of roll elements in lines. In conjunction with the manual judge head position, the persistent trajectory is a great tool for visualizing how round your loops are.

📌 - TIP

This video shows how the combination of Persistent Trajectory and Manual Judge Head Movement can help visualize a loop. Notice on the keyboard shortcuts map that for the left video, the option H is marked - automatic Judge head movement.

Reference Axis

The reference axis is an orthogonal axis that always moves with the airplane, allowing the judge to precisely identify the alignment of the airplane with the aerobatic box. Toggle with the keyboard key X or the on-screen button.

• X - red line
• Y - blue line
• Z - green line

Box

The aerobatic box is displayed (in green) in the Judge View. You can toggle it using the keyboard key B or the on-screen box button.

Acting like line judges, there are two flag displays to indicate the position of the airplane in relation to the box: one for lateral position and one for vertical position. The color of these flags has the following significance:

	Lateral Position	Vertical Position
🟢	Inside	Inside
🟠	Buffer	Above
🔴	Outside	Lower

Additional Info Overlay

Pressing the keyboard key I or the button on the on-screen button cluster toggles an additional information HUD overlay on the Judge View. This overlay shows real-time telemetry data such as speed, altitude, load factor, and heading directly on screen, allowing quick reference without switching to the time history chart.

Flight Controls Display

Pressing the keyboard key K toggles a stick position display that shows the control inputs during the flight. This is useful for understanding how the pilot is managing the controls during each maneuver.

Full-Screen Mode

The Judge View can be expanded to fill the entire window using the full-screen button. This maximizes the viewing area for detailed analysis. Press the button again or use Esc to return to the normal layout.

VR Mode

For subscribers with the VR add-on, the Judge View supports a virtual reality mode that provides an immersive judge perspective. Enter VR mode using the VR button in the on-screen controls.

Judge Location

Another very useful feature of ACROWRX is that you can place the judge at any location you want. This is great for aerobatic training when you can't fly over your preferred aerobatic boxes, or you want to fly higher for safety. It is also useful for airshow analysis, where you want to see what different locations of the public will perceive from your airshow routine.

The horizontal location of the judge is set by Ctrl+clicking (or Cmd+clicking on Mac) on the map. The green dot indicates the Judge position. The map has a feature where you can display data in 3D or 2D - keyboard key F. For setting the Judge location on the map, it is better to have the data displayed in 2D over the map to avoid parallax effects.

The location of the box in relation to the judge is set in the left menu. Three controls are available:

• Judge height - height where the judge is located in relation to the ground level of the Judge position over the map.
• Judge heading - the true heading of the box Y-axis
• Judge distance - the Judge distance to the edge of the box.

📌 - TIP

The height of the box in relation to the Judge location is determined by the category selection inside the left menu of the Analysis Window.

Saving Box's Location

The last position you set for your judge and box will be the default every time you open the Analysis Window. However, if you prefer, you can also save your box and judge location using the Save Location button on the left menu.

📌 - TIP

You can manage your saved boxes in your Personal Profile page.
