Pacenotes

The prayer book, even pace notes, english Pace note, in rallying is a book of records of the special stages (WP). They are created by reconnaissance trips before the actual competition.

At a rally one advance leads through a discovery tour of the track and logs them. The driver dictates while the copilot special characteristics of the track. The pace notes, which is so created, characteristics of events by the wayside as the course and length of sections, curve radii and - running, jumping crests and compressions contains ( valleys ), surface texture and changing, light and shadow conditions, and the like. In addition, it detects the driving data, for example, possible speeds, shifting, braking distances and the difficulty of the site. At the rally itself the passenger to the driver transmits this data through the on-board radio in unbroken succession (hence the name " prayer book " ) so that it is prepared and can be proactive.

The first prayer book was used in the Carrera Panamericana in November of 1952 by the German racing driver Hans Klenk for his driver Karl Kling - at that time with a sensational track record. It is purely team-internal data, the outcry to yellowing systems are quite different and are considered as closely guarded secrets. The word pace notes was common in German then since the 60s, in the international sports language is English Pace Score, Route note ' or generally roadbook usual.

The communication using the Aufschriebs requires an excellent combination of the two crew members and makes rallying in this sense to a team sport. The prayer book is one of the main tasks of the co-pilot relieve the driver in a rally environment.

Shortly before the start come often gravel spies (also Gravel Crews ) are used, which again especially control the distance with respect to gravel, ice and wet and update or optimizing the pace notes.
