Operation
determine the tree handicap. This at altitude elapsed time value is shown on the
screen after the word “Hdcp” for each lane.
4. As the race is run, the C-44 multiplies the actual measured at altitude times by
the E.T. adjustment factor to produce the sea-level times for:
- Reaction Time
- Interim 1 Time
- Interim 2 Time
- Interim 3 Time
- Interim 4 Time
- Final E.T.
5. The actual at altitude MPH which is calculated in the speed trap by the C-44 is
multiplied by the MPH adjustment factor to produce sea-level MPH.
6. Note that all the times and MPH shown on the monitor, scoreboard, and
printouts are sea-level values. Most drivers and spectators are familiar with the
sea-level values which are also listed in most racing publications.
7. Note that the values in the E.T. printout (Figure 3) are marked with A1 to show
that they are sea-level values that have been calculated from the actual at
altitude values using altitude adjustment factor #1. This is also true for the log
slip (Refer to Figure 4).
Figure 5 shows the results of an identical race that was run without using the altitude
adjustment feature.
