Eclipse 500 System Manual page 440

Section 16. Autoflight
pitch and lateral targets are set in this mode. When the TOGA switch on the left
throttle is pressed, the flight director will command a wings level attitude (TO ROLL)
for the lateral mode and based on current aircraft configuration (number of operating
engines and flap setting), weight and CG will set the flight director to a pitch up target
(TO PITCH).
NOTE:
Engine failure will cause an automatic reduction in the pitch target
Both TO ROLL and TO PITCH modes are exited by selecting another lateral or
vertical mode or by engaging the autopilot.
NOTE:
For the autopilot to capture a pre-selected altitude following takeoff, ALT CHG
must be selected.
GO-AROUND
When the TOGA button is pressed in the air the flight director will fix on a go-around
pitch attitude and heading. This mode will not disengage the autopilot. If the autopilot
was not previously engaged prior to this mode it can still be engaged if desired.
When the TOGA button on the left throttle is pressed, the autopilot will capture and
hold the current heading and HDG HOLD appears as the active lateral mode in the
flight mode annunciation window. In addition the autopilot will set a fixed pitch target
based on the number of operating engines, and display GA PITCH as the active pitch
mode in the flight mode annunciation window. As with takeoff mode, go-around
mode will not capture a pre-selected altitude. To capture a pre-selected altitude ALT
CHG must first be pressed.
ROLL HOLD
Roll hold is one of the primary functions of the autopilot and is activated as a default
mode if no previous mode is selected, or when a higher mode (HDG, NAV) becomes
unavailable without a subsequent flight director mode present. To utilize roll hold,
press the A/P OFF/ON button to turn on the autopilot, if no other lateral mode is pre-
selected, ROLL appears as the active lateral mode in the flight mode annunciation
window.
Roll hold will hold the aircraft in a wings level attitude if activated within 5° of a wings
level attitude. If roll hold is selected when the current angle of bank is between 5° and
30° the flight director will command an attitude to hold the current bank angle. If roll
hold is selected at bank angles greater than 30°, the flight director will command an
attitude to reduce and hold a 30° bank angle. In the event of an engine failure, the
wings level logic will default to a 2° angle of bank into the operative engine to
compensate for yaw due to asymmetric thrust.
