HUD

Overview

The Head-Up Display or HUD is a transparent display (typically located in front of the aircraft's windscreen) used to present information to the pilot without them having to look a their instruments. The design, layout, and functionality of different HUDs varies significantly. Most HUDs have multiple modes, these can be switched between by pressing the "Switch sight mode in cockpit" keybind. This article will provide an overview of each HUD design in the game. Some HUD designs are used by multiple aircraft.

HUD controls

To activate CCRP mode on HUDs you need to have placed your target point before pressing the "Switch sight mode in cockpit" key.

There are only two controls which affect the HUD, these are shown below.

Ballistic Computer Controls
Control name	Default Keybind (PC keyboard & mouse)	Description
Toggle Cockpit Sight	'	Turns the gunsight reticle (in this case the entire HUD) on / off.
Switch sight mode in cockpit	Unbound	Switches the HUD mode (typically between the standard mode and various ground attack modes)

Buccaneer HUD

The Buccaneer S.2 has it's own unique HUD design. The HUD is fairly basic and has four modes:

• Standard
• Rockets
• Bombs
• Bombs (auto)

Standard Symbology

The standard Buccaneer HUD symbology.

The standard HUD symbology is shown when the HUD is in "standard" mode, much of this symbology carries over into the other HUD modes. The standard symbology can be seen in the image to the right; in this mode the HUD is fairly basic showing only the speed and roll angle of the aircraft. A summary of the standard HUD symbology can be seen below.

Symbology	Explanation
Aircraft symbol	The aircraft symbol shows where the aircraft's nose is pointing and the "wings" on the side always remain parallel to the aircraft's wings.
Roll bar	The roll bars remain parallel with the ground, the provide a reference point from which the roll of the aircraft symbol (and thus the aircraft) can be determined.
Quadrantal marks	The four quadrantal marks remain locked in position relevant to the aircraft symbol, helping determine roll angle (relevant to the roll bar). They have no additional functionality in this mode.
Target spot	In his mode the target spot is either locked to the centre of the aircraft symbol, or behaves like a gyroscopic gunsight if rockets are carried.
Speed scale	The speed scale shows the aircraft's Indicated Air Speed (IAS) from 300 - 600 knots. When read left to right the four dots represent 300, 400, 500 , and 600 kts; the position of the line relative to the dots shows the aircraft's speed (in the image it reads ~475 kts).

In flight the two roll bars stay parallel to the ground. As the aircraft symbol (and four Quadrantal marks) stay parallel with the aircraft wings this allows the HUD to show the roll of the aircraft relevant to the ground. The speed scale shows the aircraft's Indicated Air Speed (IAS) from 300 - 600 knots.

CCIP Symbology

The standard Buccaneer HUD symbology.

The CCIP symbology is shown when the HUD is in either "rockets" or "bombs" mode. The symbology in this mode is largely identical to the standard symbology, with the exception of the target spot now showing the computed impact point of bombs or rockets. The CCIP symbology can be seen in the image to the right; a summary of the symbology can be seen below.

Symbology	Explanation
Aircraft symbol	Same as standard mode.
Roll bar	Same as standard mode.
Quadrantal marks	Same as standard mode.
Target spot	The target spot shows the computed impact point of the bombs or rockets (depending on which mode the HUD is in).
Speed scale	Same as standard mode.

When the HUD is in either "rockets" or "bombs" mode the target spot will move to display the computed impact point of the selected ordnance type. It may appear as if the target spot has completely disappeared, in the case of bombs this probably means the target spot if off the bottom of the HUD, so you need to enter a dive to be able to see it. In the case of rockets it could be either the aforementioned issue, or that you are too far away for the impact point to show.

CCIP on the HUD shows at the same range as the 3rd person CCIP marker would. This varies between different weapons. See Ballistic Computer for details.

CCRP Symbology

The standard Buccaneer HUD symbology.

The CCRP symbology is shown when the HUD is in "bombs (auto)" mode. The basic symbology is largely unchanged from the standard symbology, however quite a bit of addition CCRP symbology is added. The CCIP symbology can be seen in the image to the right; a summary of the symbology can be seen below.

Symbology	Explanation
Aircraft symbol	Same as standard mode.
Roll bar	Same as standard mode.
Quadrantal marks	The quadrantal marks function the same as in "standard mode", however they also provide increments for the range circle.
Target spot	The target spot over the CCRP target point.
Speed scale	Same as standard mode.
Range circle	The range circle appears when you are flying towards the CCRP target. It starts as an al;most complete circle and decreases anti-clockwise as you approach.
Acceptance mark	This symbol appears when a target point has been placed to indicate that you are in CCRP mode. If the target point is removed, or you are not flying towards it this symbol disappears.
3 second event mark	This symbol appears on the HUD 3 seconds before the bombs are automatically released.

To use CCRP you should place your target point (see Ballistic Computer for details) then switch the HUD into "bombs (auto)" mode. You will see the acceptance mark and range circle appear on the HUD (if you are flying towards the target). The target spot on the HUD will also move to sit on top of the CCRP target, you should manoeuvre the aircraft such that the target spot is horizontally centred within the HUD (meaning you are flying directly towards it). As you approach the target the range ring will begin to decrease, this is generally a good time to begin holing the bomb release button. Once you are three seconds away from the computed bomb release point the 3 second event mark will appear, and once the range circle completely disappears the bombs will release, hitting the marked target.

Excellent additions to the article would be video guides, screenshots from the game, and photos.
