Flight Modes

Flight modes provide different sets of parameters or behaviours to use during different operating conditions. For example a vertical takeoff and landing (VTOL) aircraft may require different mixes and trims during landing/takeoff versus level flight.

There are 9 flight modes; 8 flight modes plus the default one are available for use. Each of them can be named, has a selectable activation switch (physical or logical), a trim selection array (R, E, T, A when shown mean the mode has its own trim setting for that control, but each can be changed to a number from 0 to 9 and thus use the same value as the specified mode), and slow up/down parameters for smooth transitions between modes.

Columns

  • Flight Mode:  FM0 to FM8. Bold when active.
  • Name:  The name appears on the main view.
  • Switch:  The switch to activate the flight mode.
  • Trims (RETA):  Rudder trim from FM1, Elevator trim from FM2, Throttle trim disabled, Aileron trim FM2 and adds its own trim.
  • Transition Fade In:  Seconds.
  • Transition Fade Out:  Seconds.

Priority

The first flight mode from FM1 to FM8 that has its switch condition on is the active one. When none has its switch ON, the default FM0 is active.

Transitioning (Fade In & Out)

Each flight mode involved in the transition has its values used to calculate the final channel outputs. The two sets of values are then weighted and added together. The weighting is in proportion to the elapsed and remaining time of the transition.

  • Transition Time – Current Flight Mode Fade Out + Next Flight Mode Fade In
  • Transition Start 0% – 100% Current Channel Value + 0% Next Channel Value
  • Transition  25% – 75% Current Channel Value + 25% Next Channel Value
  • Transition  50% – 50% Current Channel Value + 50% Next Channel Value
  • Transition Start 100% – 0% Current Channel Value + 100% Next Channel Value

Editing

General editing instructions are covered on the Screen Navigation page under editing.

On smaller screen radios such as the Taranis Q X7 series another screen is used to edit the flight modes.

 

On larger screens such as the Taranis X9 series the same screen is used to edit the flight modes.

Settings

Name

Name displayed on the main view screens.

Trims

  •  Trims disabled.
  •  From/equal to flight mode.
  •  From flight mode plus own trim.

Fade In

The time in seconds that it takes to transition into this flight mode.

Fade Out

The time in seconds that it takes to transition out of this flight mode.

Global Variables

On smaller screen radios such as the Taranis Q X7 series the flight mode editing screen is used to edit the global variables. More on this under documentation for GVARS (Global Variables).

  • Select the GVAR
  • Press ENTER

On larger screens such as the Taranis X9 series the globals variables have their own GVAR (Global Variable) screen. More…

Check Flight Mode Trims

The trims for the current flight mode are temporarily removed. This is used to test the impact of the current flight mode’s trims on the outputs.
