飞机自动驾驶接通最低高度是400英尺，你可以查一下手册
襟翼不是完全收上，而是收上一部分，襟翼的作用是增大升力，如果全收上了飞机就下来了

但是机组一般不会在400英尺开AP的

空客手册上说：An AP can be engaged again 5 s after lift-off in active FD modes (if at least one FD is engaged) and, in HDG and V/S modes (if no FD is engaged).
怎么回事呢说的是离地5s以后可以接通AP。各位高人指点下撒

(b) AP ENGD Software Logic

1 Engagement conditions

This signal is at 1 (flip-flop set) if all the engagement conditions are activated:
-    Action on the engagement pushbutton switch

-    Ground conditions : engagement possible in any mode only if the engines are shut down

-    Flight conditions : engagement possible 5 s after lift-off

-    Conditions specific to the AP : AP COND (Ref. para. 2. B. (5)

-    Conditions common to the AP/FD : AP/FD COND (Ref. para. 2. A. (3)

-    Conditions common to the AP/FD and A/THR : AP/FD/A THR COND (Ref. para. 2. A. (4).

2 Disengagement conditions

This signal is set to O (flip-flop reset) when a disengagement condition is present:
-    Action on the engagement pushbutton switch, the associated AP being already engaged

-    Engagement of the opposite AP if the AP is not in LAND or GO AROUND mode

-    Action on one takeover and priority pushbutton switch

-    One engine start on the ground

-    Loss of one condition : either AP COND, or AP/FD COND or AP/FD/ A-THR COND

-    In the event of landing in dual-AP operation, disengagement of AP2 only when the LAND or GO AROUND mode is released.

离地5秒后接通AP

离地5秒后接通AP 是因为飞控计算机的空地模式转换。
这个可以参考飞控的飞行法则计算。
5秒可以等同于空地逻辑50英尺。
对飞行员来说一般是100英尺。
