In simplest terms the TAWS works just like a traffic light on the road. Red means don’t go, Yellow
means use caution, and green is clear! Should you ever come into an area of high terrain, ordinarily
shaded in red with TAWS On, the following alarm will appear:
In addition to the terrain shading in green, yellow and red, the appropriate color scheme will also
apply to towers and vertical obstructions using the guidelines above:
The AUTO setting for TAWS allows the EKP-IV to calculate the appropriate setting for you, based
on the OCH. Once the OCH reaches 3,000 feet, the EKP-IV will switch to HIGH SEP, and in areas
below an OCH of 3,000 feet the EKP-IV will operate in LOW SEP.
F. THE CALCULATOR
The Calculator functions found in the EKP-IV assist the pilot in pre-flight and in-flight calculations
for Vertical Navigation, Wind and Fuel consumption. In addition clock functions and trip data can
be found in this menu. The Calculator uses GPS data and user data for computations. All Calculator
functions are based on the active Flight Plan (see section1.1.2 to set the Active Flight Plan).
