# UI¶

In this menu, the user can manage operation elements and system variables.

## Operation elements¶

In this section, the user can rename operation elements. These are variables that have no value until an operation is performed, e.g. cruise speed and altitudes, marks to initiate landing, the route, etc.

In addition, they must first be renamed in this section, so that they can then be referenced in the setup, as in Automations (see Automations section), and then defined in the operation, in **Veronte Ops** (visit Veront Ops manual).

Operation elements are divided into 9 different types:

**Custom Points**: An operation custom point is a waypoint, a position variable (x,y,z) that can be used as a reference.**Patches**: A patch establishes a path that the UAV can fly to, they make up the route. Therefore patches include waypoints, segments, arcs and orbits.**Marks**: A mark is a reference that is placed in a patch and when the uav reaches it, an action takes place.**Prisms**: A prism is a detection area.**Cylinders**: A cylinder is a circular prism.**Runways**: These are the runways used during the take-off and landing phases.**Spots**: A spot is a kind of runway with an initial point, direction and azimuth.**Spheres**: A sphere is a detection area.**Operation Variables**: An operation guidance point is a value of the operation, such as the cruise speed.In addition to assigning a specific name, the user can also select the unit of this variable as well as its maximum and minimum values (in SI units).

## Variables¶

In this section, the user can find the name of all system variables, as well as their units and initial values. This is very useful, for example, in the case of ‘User Variables’.

Variables are divided into 4 different tabs:

**Bits**: Bits variables, 1 bit.**Unsigned**: Unsigned integer variables, 16 bits.**Real Vars**: Real Variables, 32 bits.**Features**: Features variables, 64 bits.

Note

There are 300 User variables available for each class (Bits, Unsignet and Real Vars).

To set a custom name for one of the system variables:

Click on the

**Custom Name**cell of the desired variable and**introduce the new name**for it.When the name is introduced press

**Enter**to store the name on the system.Press

**Save**to save all changes.

Error

In this version, there is a maximum amount of characters that the user can use to rename variables, i.e. there is no limit per se but there is a maximum size of the configurable (xml size).

Besides changing their name, the user can also configure the measurement units of the variables, as well as the initial value (expressed in SI units) they will have each time the system (re)starts, using the Show Units and the Initial Value (SI) cells.

By right-clicking on the **Show Units** cell, the user can select the desired units.

The table below shows all the available units in **BCS PDI Builder**.
