Halda Speedpilot

The Halda Speedpilot was an all-in-one mechanical rally computer introduced in the mid-1950s. Based on the speed set on one dial, internal gears drive an additional pointer on the clock. The driver must keep the extra pointer in line with the minute hand to stay on Pilot time. As a result, accuracy is only about 1/2 minute. Speedpilot was popular in Europe, where it was only necessary to arrive before your allotted time to avoid penalties. American rallies were timed to the second, with penalties for being both early and late, so the Speedpilot's accuracy was insufficient to determine whether the rally team was on time. Speedpilots are units with two round dials, an odometer and several buttons. There are different versions, but they all do the same job, which is to tell if you are keeping to a preset average speed. One dial sets your required average and the other has an 8-day clock with an extra hand (although some models do not have an hour hand). The extra hand is placed under the minute hand when you begin your trip or regular section and will be exactly parallel to the minute hand if the preset speed is adhered to. A useful tool for a long section. The Halda Speedpilot calculates time and distance in relation to a pre-selected average speed requirement. It takes known factors such as desired average speed, actual distance traveled and actual time used, and calculates your time in relation to the actual time. It obtains an accurate distance measurement from your speedometer cable. The average speed selection button controls a series of variations that determine the progress of the pilot hand. It is the progress of the pilot hand that continuously indicates any deviations from true time. It is very rare to find a unit in such good condition, and it would be perfect for someone who wants their rally car to have that retro look.
