HUD

Introduction

One of the first features you will notice is the HUD:

The HUD is made up of multiple displays, each of which can be configured or disabled individually.

This screenshot shows a player with an active flight plan and all automation features enabled. Some indicators only appear under specific circumstances.

There are three HUD layouts:

1. Not flying (without elytra)
2. Not flying (with elytra equipped)
3. Flying

For each layout, you can customize the HUD size, colors, and which displays are enabled.

Displays

Airspeed display

Shows the current airspeed. Because Minecraft does not simulate actual airflow, the mod assumes the air direction is opposite of the player's velocity, so this display represents forward speed.
When autothrust is enabled, the number above the scale shows the target airspeed.

Automation modes display

Shows the currently active automation modes. From left to right:

1. Thrust mode - e.g. SPEED, meaning autothrust is maintaining a specific airspeed.
2. Vertical mode - e.g. CLIMB, meaning the autopilot is climbing toward a target altitude.
3. Lateral (horizontal) mode - e.g. TRK NAV, meaning the autopilot is following a predefined track.
4. Automation status - shows which systems are active, e.g. FD (flight directors), A/THR (autothrust), AP (autopilot).

Alert display

Shows active alerts sorted by importance. Alerts are grouped by category. In this example, alerts come from the AUTO FLT (autoflight), THRUST, and F/CTL (flight control) categories.

Below the main alert text, advisory messages may appear:

• Text starting with a dash (-) indicates an action the player should take.
  Example: For THRUST LOCKED, the suggested action is THR CTRL KEYS: USE.

• Text without a dash provides additional information or guidance.
  Example: For F/CTL PROTECT LOST, the guideline is MANEUVER WITH CARE.

Full list of alerts and their meanings

Coordinates display

Shows the current coordinates. A + or - in parentheses indicates whether each coordinate will increase or decrease when moving in the current direction.
The numbers to the right represent the target coordinates.

Elytra durability display

Shows the current elytra durability. The display units can be changed in the config screen to one of the following:

• Percentage
• Time (approximate)
• Minecraft units (raw durability as shown in advanced tooltips)

If the equipped elytra is unbreakable, the display shows INFN.

Attitude display

Shows an artificial horizon and pitch lines to help orient the player. Negative pitch lines are dashed.
If a roll mod is installed, the display rotates accordingly.

Reference pitch marks (shown as paired dashes on each side):

1. 47.5° - maximum safe pitch with no thrust
2. -2.2° - optimum glide pitch
3. -38.5° - maximum safe negative pitch

Flight path display

Shows the player’s true movement path using an aircraft-style symbol, indicating trajectory and drift.

Flight directors display

Shows one or two guidance bars depending on the active automation modes.
Align your crosshair with the intersection of the bars to follow the commanded direction

Course deviation display

Shows deviation from the target course while flying under a flight plan.

• The horizontal bar shows lateral deviation.
• The vertical bar shows vertical deviation.
• The purple rectangle marks the target.
  • If it is left of center, turn left.
  • If it is above center, pitch up.

Heading display

Shows the current heading.
Below the scale, a symbol indicates the heading axis.
Above the scale, the target heading is displayed if available.

Status display

Shows contextual flight information. Example:

• CLIMB - current flight phase
• WP DIST: 423 - distance to the next waypoint (423 blocks)
• WP TIME: 0:15 - estimated time to the waypoint (15 seconds)
• FRWK CNT: 415 - number of usable fireworks in the inventory
• THR: 18.5% - current thrust setting

Ground speed & vertical speed display

Shows the current ground (horizontal) speed and vertical speed.
Negative vertical speed indicates descent.

Altitude display

Shows the current altitude.
A vertical line to the left of the scale visually represents vertical speed.
The number above the scale is the target altitude.

Radar altitude display

Shows the current radar altitude - height above terrain or void.

• If only void is below, GRND is replaced with VOID.
• If radar altitude cannot be computed (chunk unloaded or altitude too high), the flag R/ALT is shown.
