The crew doesn't talk during takeoff and landing because it's crucial for them to focus on the critical phases of flight. This includes:
- Monitoring instruments: Pilots need to constantly monitor various instruments, like the airspeed indicator, altitude, and engine gauges, to ensure a smooth and safe takeoff and landing.
- Communicating with air traffic control: They need to be in constant communication with air traffic control, receiving instructions and updates.
- Responding to emergencies: If any unexpected situations arise, they need to be able to react quickly and effectively.
Talking during these critical phases can be distracting and can lead to mistakes. It's important for the crew to be fully focused on their tasks to ensure the safety of all passengers and crew members.
