FLIGHT MODE ANNUNCIATORS (FMA)

AUTOTHROTTLE ANNUNCIATIONS ON FMA

Left Column:

  • The AT mode annunciations displayed on the Flight Mode Annunciation display (FMA) are:

    • Top row indicates autothrottle engagement mode

    • Bottom row indicates autothrottle armed mode

Right Column:

  • Depicts whether the Autothrottle is engaged or disengaged.

AUTOPILOT ENGAGE (AP/TCS) ANNUNCIATOR

AUTOPILOT/AUTOTHROTTLE SOURCE SELECTION

PFD source that currently supplies the references (primary NAV source and selected airspeed reference) for FGCS autothrottle or flight director operation. It is controlled by the SRC button the Glareshield Panel.

APPROACH STATUS INDICATION

Approach armed status is white, left of the source selector. Approach engaged status is green, right of the source selector.

Annunciator
Color
Meaning

APPR 1

White / Green

CAT I capable — armed / engaged

APPR 1 ONLY

White / Amber

CAT I is the only available approach mode

APPR 2

White / Green

CAT II capable — armed / engaged

APPR 2 ONLY

White / Amber

CAT II armed/engaged and it is the only available mode

AUTOLAND 1

White / Green

Autoland 1 (Cat IIIa) armed / engaged

AUTOLAND 2

White / Green

Autoland 2 (Cat IIIb) armed / engaged — E170 only

NO AUTOLAND

Red

Autopilot still engaged after AUTOLAND 1/2 was lost

L/VNAV

White

FMS LNAV/VNAV approach armed

LPV

White

LPV approach armed

Armed modes flash reverse video for 5 seconds, then remain steady.

CAT I (APPR 1)

  • Minimums set to BARO (DA).

  • LOC and GS armed or active.

  • Engages when LOC and GS are active and radio altitude is below 1,500 ft (or RA invalid).

  • Disconnect AP before 200 ft AGL on a CAT I approach.

CAT II (APPR 2)

Armed when all of the following are met:

  • Both PFDs set minimums to RA (and the same RA value).

  • Both NAV receivers on the ILS frequency and course.

  • Dual valid NAV / independent IRS and air data (no relevant miscompares).

  • LOC and GS armed or active.

  • Steep approach not armed or engaged.

  • Radio altitude not below 800 ft (capability freeze).

  • Airplane is approach-2 capable (valid RA, dual PFDs, etc.).

If APPR 2 is not capable, APPR 2 NOT AVAIL is posted on CAS.

AUTOLAND

Autoland is an option, enabled on the MCDU OPR CONFIG page.

  • AUTOLAND 1 — E170/E175/E190/E195.

  • AUTOLAND 2 — E170 only, and autobrake must be armed.

Typical extra requirements versus APPR 2: autoland option ON, autopilot engaged, yaw damper on, independent NAV sources on each side.

If autoland was engaged and the configuration is lost, NO AUTOLAND is shown in red.

AUTOLAND 1/2 is approach-status logic on the FMA. It is not a substitute for a real-world Cat III autoland qualification.

AUTOPILOT

  • Autopilot disengagement:

    • Either AP/TRIM DISC button is pushed.

    • AP button on the Glareshield Panel is pushed

    • Any manual pitch trim is activated

    • Stick shaker activated

    • Windshear escape guidance is activated

    • A pilot input contrary to the autopilot is made on the controls.

  • Autopilot will remain engaged in the event of an engine failure.

  • Default Modes for the autopilot are: ROLL and FPA.

LATERAL FLIGHT DIRECTOR MODES

VERTICAL FLIGHT DIRECTOR MODES

Default Modes:

  • Roll Hold (ROLL) is the default lateral mode (roll hold, wings level, and heading hold).

  • When the autopilot is engaged without any modes being selected, ROLL is automatically engaged.

  • When a vertical mode is selected without a lateral mode, the default ROLL mode is activated. The mode is displayed above the attitude indicator on the PFD

  • Flight Path Angle (FPA) mode is the default vertical mode.

Magenta FMS modes (FLCH, PTH, ASEL, ALT, GP) are shown when VNAV is active. Automatic OVSP is shown when overspeed protection is active. GA is shown during go-around.

WINDSHEAR

  • Activated between 10 ft and 1.500 ft radio altitude.

  • “WSHEAR” label displays on the PFD

  • Windshear Caution: Increasing headwind and up drafts. Amber flag and aural alert “CAUTION, WINDSHEAR”.

  • Windshear Warning: Decreasing headwind (or increasing tailwind) and down drafts. Red flag and aural alert “WINDSHEAR, WINDSHEAR, WINDSHEAR”.

  • Autopilot automatically disconnects when windshear guidance is activated.

  • Windshear alerting will last until 1.500 ft AGL or clear of windshear.

  • Windshear alerting system will not function if both radar altimeters and/or EGPWS is inoperative.

FLIGHT DIRECTOR GUIDANCE CUE IN TAKEOFF MODE

  • Magenta vertical and horizontal bar.

  • Displayed when the TO flight director mode is active.

  • Takeoff guidance crossbars maintain extended runway centerline and pitch attitude based on appropriate configuration.
