Garyo 1 Posted December 17, 2020 Share Posted December 17, 2020 After departure, I noticed the SRS not active. At about 200' agl, I put the A320 on AP 1. The aircraft slowly pitched up and activated TOGA LOCK . The auto thrust system seemed ok after passing the Thrust Reduction/ ACL altitude. Has anyone else had this problem?

Alessio75 3 Posted December 17, 2020 Share Posted December 17, 2020 Hi did you fill all the required fields in the MCDU? Link to comment Share on other sites More sharing options...
Garyo 1 Posted December 17, 2020 Author Share Posted December 17, 2020 I'm pretty sure everything was done. SRS should come on before 80kts. Link to comment Share on other sites More sharing options...
Garyo 1 Posted December 21, 2020 Author Share Posted December 21, 2020 SRS is now engaging. The problem is it is not commanding V2 +10kts. The indicated Magenta speed bug is to slow. Link to comment Share on other sites More sharing options...
SpottyMCapt 1 Posted December 26, 2020 Share Posted December 26, 2020 The SRS mode engages automatically when the thrust levers are set to the TOGA or FLX/MCT detent (when a Flex takeoff temperature or Derated takeoff@ has been selected), providing: V2 has been inserted in the MCDU PERF TAKEOFF page The slats are extended The aircraft has been on ground for at least 30 s. SRS mode, the aircraft maintains a speed target equal to V2+10 kt in normal engine configuration. When the FMGS detects an engine failure, the speed target becomes the highest of V2 or current speed, limited by V2+15 kt. The SRS guidance law also includes: Attitude protection to reduce aircraft nose-up effect during takeoff (18 ° or 22.5 ° maximum in case of windshear) Flight path angle protection that ensures a minimum vertical speed of 120 ft/min Note: If during takeoff the flight crew inadvertently sets an altitude on the FCU below the current altitude, the aircraft will remain in SRSmode unless the flight crew engages V/S mode. A speed protection limiting the target speed to V2+15 kt. Link to comment Share on other sites More sharing options...
