2.4.6 Using the AIR DENSITY Button

Pressing the AIR DENSITY button displays the Air Density screen, see Figures 2-12 and 2-13. This screen contains the temperature value, pressure value, and Air Density Correction Factor (ADCF). Press the AIR DENSITY button to advance the "X" cursor to the next field. To change the value or state of an item at the "X" cursor, use the UP and DOWN arrows. The 35360A TRACKER Display displays the Air Density Correction (ADC) annunciator in the upper left-hand corner of most screens if the air density correction is enabled, see Figure2-12.
