Malfunction Overview

Malfunctions have three possible states:

State	Text Color	Description
Active	Red	The malfunction is in effect.
Armed	Orange	The malfunction will automatically become active once the preselected conditions are met.
Normal	Green	The malfunction is not Armed or Active.

After selecting a Button from within the Sections GroupBox and then selecting a malfunction from within the Malfunctions Selection GroupBox, read the text shown in the Malfunction Description GroupBox. If the cause and effects describe the condition desired, then decide whether to activate the malfunction immediately or to have it activate automatically based upon some preselected conditions.

See the Immediate Activation or Preselect Conditions for Activation sections for more details.

Note: The Failure Summary will report the number of Active and Armed malfunctions and will list the currently Active and Armed malfunctions. See related topics.

Sections

The Sections GroupBox contains several Buttons. Each button describes a major area of the aircraft like, Electrical, Fuel, Hydraulics, Engines, etc. If there are more sections than can be listed, the Previous and Next Buttons will be enabled.

Select the appropriate button to update the list of available malfunctions for the current section. The available malfunctions will be shown in the Malfunctions Selection GroupBox.

Note: A Section must be selected before any malfunctions will be displayed in the Malfunctions Selection GroupBox or before any description will be displayed in the Malfunction Description GroupBox. The currently selected section, if any, is shown at the top of the screen next to the Current Section: Text.

Malfunctions Selection

The Malfunctions Selection GroupBox contains several Buttons. Each button corresponds to a malfunction available in the selected section. If there are more malfunctions than can be listed, the Previous and Next Buttons will be enabled.

Select a button to update the cause and effects shown in the Malfunctions Description GroupBox and to update the malfunction that the Immediate Activation and Preselect Conditions for Activation Radio Button / GroupBoxes act upon.

Note: A malfunction must be selected before any cause and effects will be displayed in the Malfunctions Description GroupBox. The currently selected malfunction, if any, is shown at the top of the screen next to Current Malfunction: and at the bottom of the Activate Malfunction and the Arm Preselect buttons.

Malfunction Description

The Malfunction Description GroupBox is automatically updated when a new malfunction selection is made. The information displayed consists of the Cause and Effects for the selected malfunction.

Immediate Activation

Select the Immediate Activation Radio Button to enable the Activate or Deactivate Malfunction Button and the Clear All Malfunctions Button. Once these buttons are enabled, select the Activate Malfunction Button to immediately activate the current malfunction or the Deactivate Malfunction Button to immediately deactivate the current malfunction.

Use the Clear All Malfunctions Button to clear all active malfunctions. Selecting this Button will not affect any armed malfunctions.

Preselect Conditions for Activation

Select the Preselect Conditions for Activation Radio Button to enable the ComboBoxes, EditBoxes, Arm or Disarm Preselect Button and the Clear All Preselects Button.

After selecting the malfunction and before pressing the Arm Preselect button, conditions for the automatic activation of the malfunction can be entered using the three rows of ComboBoxes and EditBoxes.

The first row has two ComboBoxes and one EditBox. Use the first ComboBox to select a variable, like Airspeed, then use the second ComboBox to select the condition, like Less Than or Greater Than, then use the EditBox to enter the value to compare the variable with.

On the second row there is a ComboBox. If a complex automatic activation condition is desired, use the ComboBox to select either AND or OR to link the two conditions defined in the first and third rows. If a complex automatic activation condition is not desired, leave the ComboBox blank.

The third row looks and is used just like the first row.

After the desired preselect information is entered, select the Arm Preselect Button.

Note: If the currently selected malfunction is already armed, then the ComboBoxes and EditBoxes will show the current preselected conditions. Use the Disarm Preselect Button to disarm the currently selected malfunction or use the Clear All Preselects Button to disarm all Armed malfunctions. Once an armed malfunction becomes active, the conditions that caused its activation are no longer shown.
