FMA (Flight Mode Annunciator).

Two FMA are provided on the instrument panels, to keep the crew continuously informed about the system status. IN FD (Flight Director) mode of operation, the left FMA displays the modes engaged in the No. 1 system and the right FMA, the modes in the No. 2 system. As soon as the autopilot is engaged, the two FMA display the autopilot modes in parallel. 1. THROTTLE light (red). 2. AP (AutoPilot)light (red). 3. ILS light (amber). 4. HORIZON light (amber). 5. HEADING light (amber). 6. NO AUTOLAND light (amber). 7. AP TRIM light (amber). 8. MONITOR light (amber). 9. RESET button. 10. AP 1 light (blue). 11. AP 2 light (blue). THROTTLE - ARM - ROLL- PITCH The annunciator windows will show the different modes of operation and are referred to as T A R P T - AUTOTHROTTLE MODE ANNUNCIATION. A - ARMED MODE ANNUNCIATION. R - ROLL MODE ANNUNCIATION. P - PITCH MODE ANNUNCIATION. There is no need to memorize all the different annunciations, they are rather self explanatory. A couple of examples The autothrottle is set to EPR CLIMB. Altitude is armed. Autopilot modes are HEADING SELECT and IAS HOLD. The autothrottle is set to hold a speed of 164 knots. Auto land is armed. We are tracking the localizer and have captured the glide slop. Autopilot No. 2 is engaged. The autothrottle is set to hold Mach 0,73. Altitude is armed. The autopilot is in NAV TRACK mode, which means that the FMS is engaged in lateral navigation and will keep the track. The PITCH mode is VERTICAL SPEED.
