A loud, rhythmic scream in a helmet, which can cause cognitive dissonance in an unprepared viewer - this is what the work of a navigator looks like in the cockpit of a rally car. For those watching the race for the first time, this stream of numbers, letters and strange words may seem like a chaotic collection of sounds, devoid of logic. However, behind this flow lies a highly sophisticated navigation system developed over decades of motorsport evolution.
Your task as a viewer is to understand that the driver is practically blind at this moment. He cannot see the road beyond the hood, and at a speed of 150 kilometers per hour, it is physically impossible to see the next turn. That's why the navigator becomes the pilot's eyes, turning an unknown track into a clearly structured route, where every turn, hole and bump has its own digital code.
In this article we will analyze in detail how it is formed road book, what the danger levels from “1” to “6” mean and why the navigator shouts “Kale-Kale” or “Don-Don”. You will understand that rally is not just a race for speed, but a complex chess match, where the cost of a mistake is calculated in fractions of a second or, in the worst case, the life of the crew.
Transcript Philosophy: How a Roadmap is Created
The basis of communication in rallying is road book or transcript. This is not just a recording, it is the result of many hours of work by the crew during reconnaissance (river). A few days before the race, the pilot and navigator drive each section of the special stage (SS) twice or three times in a regular civilian car at the permitted speed.
During the process, the pilot dictates how he sees the turn ahead, and the navigator writes this down in his notebook, using the team’s convention system. There are many recording systems, for example the popular system Pacemaker or systems developed by specific teams like Prodrive or M-Sport.
The essence of the process comes down to turning a visual image of the road into an auditory signal. The pilot must hear the command and immediately, without delay for comprehension, carry out the action. Therefore brevity and clarity — the main requirements for the transcript.
How does the navigator manage to take notes?
The navigator uses a voice recorder or a special tablet, but the classic method is a paper notebook with a ruler. Records are kept in abbreviated form, using abbreviations known in advance to both pilots. After the river, the transcript is printed in its final form in a special book, which is attached to the cabin.
It is important to understand that a transcript is a subjective document. It reflects exactly how this particular pilot wants to pass this section. One driver will choose to take a corner in a higher gear, another will choose to put the car into a steeper drift, and the numbers on their notebooks will be different.
Digital danger scale: from 1 to 6
The central element of the navigator's shouts are numbers. They indicate the degree of steepness and, more importantly, the danger of the turn. Unlike regular roads, where signs limit the speed, in a rally the signs are replaced by the voice of the co-driver.
The most common system is where the number 1 denotes the most dangerous, slow and sharp turn, requiring an almost complete stop or driving in first gear. Digit 6 (or sometimes higher) means a long, fast and gentle curve in the road that can be passed at maximum speed.
In rallying, the inversion rule applies: the lower the number, the more dangerous and slower the turn. Number 1 is almost 90 degrees and low speed, number 6 is a barely noticeable bend at high speed.
Between these extremes are intermediate values that give the pilot an accurate understanding of the required braking. The navigator may use fractional values such as "4-5" or "3-4" to indicate the nuance of steepness. There are also designations for the composition of turns, for example, “left 3 to right 4.”
The accuracy of this system is critical. If the navigator makes a mistake and says “4” instead of “2,” the pilot will not have time to brake, which will lead to him flying off the track. That's why on reconnaissance every meter of the path is worked out.
Verbal modifiers and clarifications
A number alone is not enough to describe a car's cornering behavior. The road in the forest or mountains is unpredictable, so clarifying words are added to the numbers. They describe the road profile, surface and vehicle behavior.
For example, the word “narrows” warns that after entering a turn the road becomes narrower and you need to be careful. The word “expanding,” on the other hand, gives the green light to add gas earlier. You can often hear indications of bumps, holes or changes in the surface.
- 🚧 Jump — there is a springboard ahead, you need to be prepared for the wheels to lift off the ground.
- 💧 Creek — ford or water hazard, possibly slippery bottom.
- 🪨 Rock — stones on the road, dangerous for tires and suspension.
- ❄️ Ice — an area of icing or very slippery ground.
The navigator also indicates the distance to the turn. This is done so that the pilot starts braking at the right moment. The commands sound like “100, 50, 30, 20, 10, now!” This allows the driver's actions to be synchronized with the terrain.
Pay attention to the navigator's intonation. In tense moments, the voice becomes smoother and more monotonous so as not to confuse the pilot, and before difficult sections a warning harshness appears in the voice.
Synchronization and timing: the language of distances
The most difficult thing about being a navigator is timing. You need to shout “3 left” not at the moment the turn begins, but in advance so that the pilot has time to react. The distance for which the warning is given depends on the speed of the section.
On fast sections, the navigator begins counting the distance long before the turn. Standard marks are 100, 50, 30, 20, 10 meters. At very high speeds the count can be hundreds of meters. Accuracy is vital here, as at 180 km/h the car travels 50 meters in less than a second.
You can often hear the command “Square” or “Sharp”. This indicates the rotation geometry. “Square” means a 90-degree turn where you need to practically stop. “Sharp” is an even sharper turn, often with a radius of less than 90 degrees.
Crews use special training to practice synchronization. The pilot must learn to “hear” the road through the navigator’s voice. Ideally, the navigator's voice becomes an extension of the pilot's thoughts.
| Team | Meaning | Pilot action |
|---|---|---|
| 1 (One) | Very sharp, dangerous turn | Full braking, 1st-2nd gear |
| 3 (Three) | Middle turn | Relieving the gas, using the handbrake or shifting |
| 6 (Six) | Fast, gentle bend | Little or no braking |
| Don't Cut | Danger on the cut (wood, stone) | Keep the trajectory within the rut |
| Long | Long turn | Do not open the gas ahead of time |
Coverage Features and Security Teams
The rally takes place on different surfaces: gravel, asphalt, snow, ice. Each surface dictates its own rules for reading the transcript. On gravel, turns are “tightened” by the car, on asphalt they require a clear trajectory.
The navigator must warn you about changes in the surface. The phrase “Mud in the turn” or “Ice in the shadow” can save you from relegation. On snow rallies such as Rally Sweden, commands about the depth of the snow and the presence of “snow porridge” on the roadsides are important.
⚠️ Attention: The command “Kale-Kale” (Careful) or simply “Caution” means the presence of a hidden danger that cannot be described in numbers. It could be a protruding stump, a sharp hole or a narrow bridge. Ignoring this command often results in damage.
There are also commands for specific situations. For example, "Over Crest" (over a ridge) warns that beyond the top of a hill the road drops sharply down or changes direction, and the exit from the turn is not visible. The pilot must be prepared for the fact that the car may “dive”.
The description of the exit from the turn also plays an important role. The “Exit narrow” command forces the pilot to keep the car strictly in the center so as not to hit a tree or stone at the exit when the speed has already been gained.
Psychology and stress resistance of the crew
The work of a navigator is a colossal burden on the psyche. A mistake in one number can cost you a victory or lead to an accident. At the same time, the pilot must completely trust the voice in the headset, ignoring the self-preservation instincts that scream “brake” when the navigator says “throttle.”
Between the pilot and the navigator there must be an ideal psychological contact. They often live together on the same team for years. Any irritation or mistrust in the cockpit immediately affects the result.
☑️ Qualities of an ideal navigator
The navigator also keeps track of time. In a rally there are time limits for completing sections and crossings. The navigator controls the timing so that the crew is not fined for being late for the start of the next special stage. This adds another layer of complexity to their role.
⚠️ Attention: Any electronic navigation aids are prohibited in the rally. GPS navigators, radar detectors and real-time telemetry are strictly prohibited. The only source of information is the navigator's voice and a paper transcript.
The navigator's physical fitness is also important. Overloads in the car reach 3-4G. The navigator must maintain balance, read notes and speak clearly while being thrown from side to side. Often navigators are injured just as much as pilots.
FAQ: Frequently asked questions about rally navigation
Why does the navigator shout and not speak calmly?
Loudness and rhythm are necessary to overcome engine, suspension and tire noise, as well as to attract the pilot's attention in a stressful situation. Screaming helps to break through the “screen of noise” and the driver’s concentration.
Can a pilot drive without a navigator?
Theoretically yes, if he knows the track by heart, but in professional rallying this is impossible. The speeds are too high, and the tracks change after each car passes. Without a navigator, the pilot is blind and will not be able to reach maximum speed safely.
What does the navigator do if he makes a mistake in the recording?
If an error is discovered during a race, the driver must immediately react to the actual situation, even if it contradicts the transcript. Experienced pilots often “see” the road better than they hear, and may ignore a command if they see danger. After finishing, the transcript is corrected.
Are the same recording systems used in all countries?
No, there are many systems (McNeil system, Tuthill system, factory command systems). However, the principle “digit = danger” is universal. Crews from different countries, when placed on the same team, are often retrained to use a single recording system.
⚠️ Warning: Trying to replicate the rally driving style on public roads is deadly. In a rally, the track is closed, prepared and safe (relatively). On a normal road, the “gas to the floor” reaction on command can lead to tragedy.
Understanding the navigator's language opens up a new level of rally perception. Now, listening to these rhythmic shouts, you will know that behind each number there is calculation, experience and the highest skill of two people working as a single mechanism.
