The flight UI or HUD of Pioneer is made of several different parts:

(Notice: this article contains elements from an upcoming release. The curious could try building master until that :) )

Parts of the flight UI

 

Central reticule

02 01 deltaV.png
Along with the crosshair, the central reticule shows vital flight related information. With the help of them, you can navigate around, performe transits to anywhere without an autopilot.

 

DeltaV bar

The bars on the left side of the reticule are displaying the deltaV reserves of your ship. You could consider it as a "fuel" display, since deltaV is the capability of your ship to change speed.

There are two bars there. The left one is your current speed. The right one is the deltaV capacity of your ship. Beneath it the fainter bar shows the maximum deltaV capacity.

As your speed increases, the left bar will start to build up, which shows the speed of the ship proportional to it's deltaV reserves. Practically if the speed bar is bigger than the deltaV bar, you will not be able to slow down and stop, because you don't have enough propellant (fuel). Usually it's wise to keep some in reserve, so you have room for corrections if something goes unexpected. The autopilot uses about 1/3rd of it for acceleration, another 1/3rd for deceleration, and the remainder is saved.

 

 

Orientation displays

Orientation displays

There are three orientation displays on the central reticule. There are toggleable numerical displays available for each.

  1. Compass: Shows your orientation in relation to the cardinal directions of North, East, South, West. Useful if you need to navigate to a downed ship in distress for example.
  2. Pitch indicator: Shows your pitch relative to the ground. The central tick means you are parallel to the ground, the upper and lower are 90°: looking directly up or down respectively, and the smaller inbetween ones are 45°.
  3. Roll indicator: Shows your roll (bank) relative to the ground. The shorter half of the "L"s always point towards the ground. That can come in handy in space too, they always point towards the planet or target, so you can easily feel where you need to rotate to find it.

 

 

Flight data 

02 03 data.png
RTENOTITLE

Flight related data are displayed on the sides of the reticule. If the frame of reference data isn't shown on the right side, a compact version is shown on the left.

  1. Name of the object for the displayed data.
  2. Closing speed. The speed you are approaching your target, which might not be the same as your speed relative to it. If negative, then you are getting closer to your target, if positive, you are getting further away from it.
  3. Distance to the target and relative speed. Measured to their surface.
  4. Approximate braking distance, measured in the same unit as your speed. An approximation of the distance you will need to slow down to a full stop relative to the target or frame respectively. It's a helpful navigation aid, since you will see, how far from your target you need to start decelerating in order to stop close to your target. It is based on the thrust of your main thrusters, so you need to turn your ship around, and decelerate with them. If your distance is smaller than the braking distance, you will not be able to stop in time, so you will overshoot your target (or hit it).
  5. Display selector: allows switching the display to show data related to your current frame, navigation target or combat target.
  6. Braking distance bar, complementing the braking distance readout. A visual display of your braking distance in relation to your distance to your target. There are two bars on top of each other that fill up as you are getting close to your target: a gray one for your retro thrusters and a white one for your mains. If the bar is filled up, it's 100%, if it starts to fill up from above with a red bar, then you will overshoot.  Only shows if you are getting closer to your target (closing speed is negative). Note that the bar will fill up as you are getting closer to your target, even if you aren't accelerating.
  7. Reference frame: The object you are measuring your speed against. (Since without this speed is meaningless)
  8. Closing speed towards the surface of the reference frame.
  9. Distance to surface of the reference body.

Indicators

There are several indicators visible on the flight display to aid navigation and orientation: Some of these are also displayed on the inside of the central reticule, to show their direction, if out of view.

 

Vector indicators:

  • Prograde.png Prograde: The direction of flight. There's a white one for the current frame of reference and also a yellow one for the navigation target if it is moving, when you are not in its frame (like an orbiting space station or planet).
  • Retrograde.pngRetrograde: The opposite of the direction of flight. There could be a yellow one of this too.
  • Maneuver.pngManeuver direction if there's a maneuver planned in the orbital map. You need to accelerate in this direction to complete the maneuver. The central reticule will also display the time of burn at the bottom.
  • Zenit.pngZenit: The direction away from the center of your reference frame. Useful for blastoff for example.
  • Target.pngTarget: Displayed on the center of the selected navigation (yellow) and combat (red) target.

Direction indicators:

These are essentially the crosshairs for each viewing direction (Numpad 8,4,6,2,9,3), and they also show up when you rotate the view using the middle mouse button.

  • Crosshair fwd.pngForward crosshair: Points to the front direction.
  • Crosshair bwd.pngBackward crosshair: Points to the rear direction.
  • Direction.pngView direction crosshairs: Down, Right, Up, Left. Practically little arrows that are pointing towards forward direction. (eg: if the arrow points up, you have to look up for forward view.)
  • Crosshair dir.pngDirection to front: This is only visible if the view is rotated, and it always points towards the crosshair, so the pilot always knows where forward is.

In-space Indicators

Indicator-pluto-opened.jpg
Bodies in space are shown with an icon and a name. If multiple bodies are close together, they are collapsed, and only the most "important" one is shown, with a "+" after its name, to show that it represents multiple bodies.

If you click on a body, you will select it as your nav target (or combat target in case of a ship). You can de-select it by Ctrl-clicking on it. If you click on a body that represents multiple collapsed bodies, you will get a pop-up menu that lets you pick which one you actually want to target.

Icons:

  • Icon sun.png Star
  • Icon gasgiant.png Gas giant
  • Icon planet.png Planet
  • Icon moon.png Moon
  • Icon asteroid.png Asteroid
  • Icon orbital.pngOrbital station
  • Icon surfaceport.pngSurface starport
  • Icons ships.png Different types of spaceships (Fighter, Courier, Shuttle, Transport, Cargo shuttle, Freighter)

Time controls

It shows the current time and date, and provides time acceleration controls.

Time acceleration levels are:

  • || Pause - Pressing it twice will open the Settings window.
  • > 1x
  • >> 10x
  • >>> 100x
  • >>>> 1 000x
  • >>>>> 10 000x

Depending on the location of the ship, available time acceleration levels can be limited. Near planets for example. You can still force higher levels pressing their button while holding [Ctrl]. But be aware that forcing time acceleration can be dangerous. And it won't switch back to 1x when the autopilot has arrived at its destination.

 

Screens

These are controls for the internal and external views, and additional screens like maps, data access and communications.

  • F1: Switch views: Internal, external and sideral. External is anchored to the ship orientation, sideral is anchored to the orientation of the sun.
    All views can be rotated around with the [middle mouse button], and the Numerical Pad keys can be used for view manipulation too.
  • F2: Map screens. These can be used to plot hyperspace jumps, navigation around and access information of star systems.
  • F3: InfoView screens. You can access general ship, cargo, personal, crew and mission information from here. There are some functions too, like in-flight refueling from cargo hold.
  • F4: Comms screen. While docked, it is used to communicate with the space station. While in flight, autopilot and settlement targeting functions can be accessed with it

To the right of these buttons, there is an air pressure (atmosphere density) display, measuring in Earth atmospheres.

Above these buttons, one can also find weapon information and heat bars, if applicable.

 

 

Radar

If the Radar equipment is installed on the ship, a disc shaped planar radar is shown. Useful to judge the position of other ships and station relative to the pilot's ship.

There are two kinds of radar display in the game. You can switch between them by pressing [right mouse button] on them.

  • 3D Planar: The classical Elite style radar display.

    Azimuthal.png

The plane of it shows the plane of the ship, as if it was viewed from up top and behind. The ship is in center, and contacts are shown as small dots. If they are above or bellow the plane of the ship, these dots will have a thin line above or bellow them, indicating their height to this plane. 
There are two sizes available, can be swithced with the Compact scanner option in the Settings window.
There are some keyboard shortcuts available:

    • \: Toggle scanner mode. Auto will put the furthermost contact on the edge, and dynamically adjust the range based on that. In manual mode, a specific range can be selected.
    • ]: Increase scanner range
    • [: Decrease scanner range
  • 2D Azimuthal: Projecting the globe onto a 2D plane. Doesn't really show distance data directly, only directional, but it's omnidirectional.
    The range can be adjusted with the [mouse wheel]. The dots fade out as they are getting out of the set range.
    • The inner circle shows what's in front of the ship.
    • Then four segmented ring shows what's to each side of the ship
    • The outter circle shows what's behind the ship. The circle itself is what's exactly behind.

 

Ship functions

These buttons can be used to access ship functions like Equipment window (Missiles, ECM), Rotation damping, Alert states, Flight modes, Landing gear, Hyperdrive and Limited thrust options. More info about them can be found in the manual.

Above the buttons are the indicator of the Flight mode (Manual, Set Speed, Autpilot), and the geographical coordinates for the current frame of reference object.
