Arrival Control

The arrival control (commonly called the ATC) is situated at the end of a road section between stages and it's purpose is to give the competitors an end time for completing the road section, at the ATC, competitors are issued with their stage start time which must be a minimum (and usually is) 3 minutes after their ATC time. Generally an ATC consists of 3 people, one person keeping a check sheet, one person writing on time cards and one person who acts as a spare (usually holding the clock).  

Start

The start control is situated after the arrival control and marks the start of the special stage, one marshal keeps a check sheet of the times each car starts the stage, one marshal writes on their timecard and the third marshal gives the car a 30 second, 15 second, 10 second verbal countdown followed by a  5-4-3-2-1 countdown both verbal and visual starting the stage, a fourth marshal hold a flag across the drivers side of the windscreen. (most events now use a traffic light system to countdown from 10 - 0).

Flying Finish

The flying finish marks the end of the special stage in terms of competitiveness, as the car crosses the "finish" the time is recorded by the flying finish on the check sheet and is relayed to the stop line (via a buzzer if the line of site is not available) to write on the competitors time sheet.

Stop Line

The stop line is situated around 200metres after the flying finish and is where the time cards of the competitors are completed. Here, one marshal receives the time and may also run the check sheet, although it is better if these two jobs are done by two marshals, a further marshal completes the competitors time card with the information relayed to them.

Passage Control

The passage control serves two purposes on a special stage rally. The first is to collect time cards (or usually portions of time cards) and transfer these times to rally HQ or results service. It is useful to have one person dealing with competitors timecards with one person keeping a check sheet along with a third person to communicate the field results back to the main results team.

Service "In"

The service "in" control is very much like an ATC but no start time is nominated, instead the service interval allowed is sometimes written on the time card, and in other cases it may not be. Service "in" controls are often used as card collection points as well. The staffing requirements are similar to to ATC's with one person dealing with time cards, one person dealing with the check sheet and a third as a spare or phoning back results.

Service "out"

The service "out" control gives competitors a time for them leaving the service area, it is useful to have one marshal dealing with timecards, a second keeping a check sheet and the third as a spare.
