Standard callouts are predefined words and phrases used by flight crew members. For example, during takeoff, the Pilot Flying (PF) controls the aircraft, while the Pilot Monitoring (PM) makes callouts such as “Flaps checked”, “V1”, and “Rotate [speed in knots]”.标准喊话是飞行机组人员使用的预先规定好的标准化用语。例如，起飞阶段，操纵飞机的飞行员（PF）负责操控飞机，监控飞行员（PM）需进行标准喊话，如 “襟翼已检查”“V1 速度”“抬轮 [×× 节]” 。 Standard callout means using a fixed set of words and phrases to communicate critical information in the cockpit. It ensures every pilot uses the same terms in the same situation, reducing confusion. Typical callouts include “80 knots”, “1000 feet”, “500 feet”, “minimums”, “runway in sight”. Standard callouts help both pilots monitor status and make coordinated decisions. They are a key part of SOP and CRM. Airlines publish standard callout lists in their operation manuals. 标准喊话是指在驾驶舱内使用固定用语传递关键信息，确保所有飞行员在相同场景下用词统一，减少混淆与误解。典型喊话如：80 节、1000 英尺、500 英尺、最低高度、跑道可见等。标准喊话有助于两名飞行员共同监控状态、协同决策，是 SOP 标准程序与 CRM 机组资源管理的核心组成部分。航空公司在运行手册中明确发布标准喊话清单。

The Pilot Flying (PF) controls the aircraft, while the Pilot Monitoring (PM) should make a call - out such as: “Check speed, altitude, and flap position.”操纵飞机的飞行员（PF）负责操控飞机，监控飞行员（PM）应进行如下标准喊话：“检查速度、高度及襟翼位置。”

Yes, it is very important. It serves as a cross - check, helping to reduce human error and ensure flight safety.重要，它非常关键。标准喊话起到交叉检查的作用，有助于减少人为差错，保障飞行安全 。

If ATC or pilots uses non-standard words in communication, it may cause misunderstanding with each other. Sometimes it may lead to accident, such as runway incursion.若空管或飞行员使用非标准用语，可能导致双方误解，有时会引发事故，如跑道入侵。

If an air traffic controller has a strong accent, it may cause misunderstanding with the pilots, it’s dangerous for the flight safety.可能导致飞行员与空管之间产生误解，对飞行安全构成威胁。

I will readback his instruction for double check and if I have any doubt of the instruction, I will confirm with the controller before further action.会复诵空管指令以双重确认；若对指令有任何疑问，在采取进一步行动前会向空管确认。
