Calculate the Air Density Index (ADI) and Density Altitude for this
example.
First, clear the memory on your calculator, including temporary
and semi-permanent entries.
KEYSTROKES
1. Enter track elevation:
2. Enter current local measured weather conditions:
3. Calculate ADI and Density Altitude:
Calculating and Using a
Fuel Correction Index
Note: In this example, it is assumed that your current air/
fuel settings and jet numbers are correct for your engine's
requirements at wide open throttle. This example uses a basic
Holley carburetor with squared jetting and identical primary and
secondary main metering circuits. This example demonstrates
how to compare a baseline ADI value to a new ADI value and
the meaning of the difference between the two. In practice, this
example can be used between ADI calculations at the same track
throughout the day, or, between ADI calculations at two different
tracks; the theory is the same.
