At the start of the practice sessions on Friday and Saturday at a Grand Prix race, the cars appear on the screen in the order of the number of the car. When they leave the pit lane, they are shown in the order in which they leave. When they record a lap time, they appear in the order of the lap time, with the fastest lap at the top of the time screen. The drivers' names are abbreviated, on the left.

Screen 1 starts showing all the cars in grid order with the words IN PIT in the lap time column.

During the first lap the screen updates the order as the cars cross the first intermediate position of the three timing and speed locations known as: Intermediate 1, Intermediate 2 and the Start/Finish line.

As each car crosses the Start/Finish line its number and driver's name is shown in white. When the leader crosses the Start/Finish line all other names go yellow. When the car leaves the pits, the word OUT is shown in the most recent lap time column, and the duration of the pit stop appears in the last sector column.

Screen 2 is made up of two sections. The top is a scrolling area displaying a full lap of timing data for each car every time it crosses the finish line; the bottom section shows the top six positions from the two intermediate timing points, the finish line and a fourth location on the circuit (usually the fastest part).

Scrolling Area

The top half of Screen 2 shows the sector time and speed information as well as the lap time for each car as it crosses the Control/Finish Line. It also shows the speed achieved through the additional speed trap by the car on that particular lap, the number of laps completed and the time difference between cars.

FLAG This will be shown under the lap time column to indicate that the session has ended and the checkered flag has been shown.

Blank line Generated when the timing systems are prepared for Q2 and Q3, prior to the start of these sessions.

Speed Classification Area

The bottom half of Screen 2 shows the current top six speeds for the session at each of the intermediate positions, the Start/Finish line and the speed trap together with an abbreviation of the driver's name to which the speed relates. The speeds are shown in kilometers per hour, as always in F1.

Practice and Qualifying

During practice and qualifying sessions, this area of the screen will also show three pieces of information about the competing cars.

On Track Indicates the number of cars that are currently on the circuit.

In Pits the number of cars currently in the pits.

Screen 3: Race Control Messages

Screen 3 has the same format for all sessions and is made up of two parts.

Race Control Messages

The top half shows messages sent directly from Race Control along with the time each message was sent. The list of messages scrolls upwards so that the most recent message is always shown at the bottom. The most recent message is displayed in magenta for one minute after which it will revert to yellow.

These messages are used to inform everyone about the status of a session (e.g. Delayed Start, Chequered Flag, Red Flag, etc.) and any additional information Race Control wishes to convey (e.g. car 7 stopped at turn 10).

Weather Information

The bottom half of Screen 3 shows weather information and is split into three sections.

The section on the left shows a map of the circuit with an arrow pointing in the direction in which the wind is blowing. The map is orientated such that the top of the screen is north.

The central section contains a graph showing the weather data collected over the previous three hours. This graph will change every few seconds to show, sequentially: Temperature both the track and air temperatures in degrees Celsius; Wet/Dry the prevailing track condition (wet or dry); Wind speed the wind speed in meters per second; Humidity the relative humidity; Pressure the atmospheric pressure in millibars. The section on the right shows the most recent weather readings.

Cars remain number order until they set a lap time, when they are put into performance order.
