感谢敬晓龙教员提出的问题。
系统章节说 A/THR SOFT MODE 在 ALT, ALT CST 和 ALT CRZ 模式下都可以激活，但是在 SOP 的爬升部分却说只能在 CRZ 模式：
空客回复说确实这几个模式下都能激活，SOP 的描述会在明年修改。具体参考 TechRequest 原文：
Q:
Can A/THR SOFT MODE be activated in ALT or ALT CST mode?
A:
Airbus would like to thank you for your remark.
Airbus confirms that A/THR SOFT MODE can be activated in ALT or ALT CST as described in A350 FCOM Aircraft Systems/AFS – Flight Guidance/Autothrust/A/THR Modes/SPEED MACH mode.
However, the layer 2 note in A350 FCOM/Procedures/Normal Procedures/Standard Operating Procedures/Climb/Initial Climb, as pointed out by CSC, needs to be revised. The information “and A/THR soft mode is not available” will be removed. The update will be released in the A350 FCOM minor revision in January 2021. CSC will receive the updated content in CSC’s A350 FCOM planned revision that comes on or after the A350 FCOM minor revision release in January 2021.
