AUTO FLIGHT - FLIGHT GUIDANCE<br />
AP/FD COMMON MODES - TAKEOFF<br />
In SRS mode, the aircraft maintains a speed target equal to V2+10 kt in normal engine<br />
configuration. When the FMGES detects an engine failure, the speed target becomes the highest<br />
of V2 or current speed, limited by V2+15 kt.<br />
The SRS guidance law also includes:<br />
‐ Attitude protection to reduce aircraft nose-up effect during takeoff (17.5 ° or 22.5 ° maximum in<br />
case of windshear)<br />
‐ Flight path angle protection that ensures a minimum climb slope of 0.5 °<br />
‐ A speed protection limiting the target speed to V2+15 kt.<br />
Note: If during takeoff the flight crew inadvertently sets an altitude on the FCU below the<br />
current altitude, the aircraft will remain in SRS mode until the flight crew takes some<br />
other action.<br />

RUNWAY (RWY)<br />
The RUNWAY mode has two submodes:<br />
‐ RWY mode, which gives lateral guidance orders during takeoff roll and initial climb out (up to<br />
30 ft RA) if a LOC signal is available<br />
‐ RWY TRK mode, which gives lateral guidance on the track the aircraft was flying at mode<br />
engagement (at 30 ft RA).<br />
