...for all the goodies on the tray table.
Flaps: Our performance section in the manual lists a 'S' speed of 214 kts at max weight. 'S' speed is defined in my manual as the minimum slat retraction speed. Since we are in Config 1 + F , no matter if we take off in Config 1, 2 or 3 , we then have to wait until we reach 214 kts before we can initiate the retraction to Config 0. But we know that the flaps start to autoretract at 210 kts. I ws just about to write a note to our fleet, when I ckecked the limitations section in our manual. There is a note next to the flap limit speeds that says: Do not exceed the limit for any flap setting (except as directed by a procedure or during flap retraction) to prevent excessive wear on the flap assembly. That says it all. Even though getting an auto retract on other aircraft means that you must have gotten too fast for the given config and the plane is trying to save itself from you, here it is OK, there even is no way around this. I was told (engineers, please confirm or deny) that the loads on flaps are not really that severe at a setting like 1+F , this only gets to be a big factor when the flaps are out much further , like in Config 3 or FULL.
