Final answer:
The correct answer is D) All of the Above, which includes Altitude and Airspeed, Weather Conditions, and Aircraft Identification as critical components in Routine & Safety of Flight.
Step-by-step explanation:
In regards to what must be included in Routine & Safety of Flight, the correct answer is D) All of the Above. This encompasses several critical aspects that ensure the safety and effectiveness of flight operations. Altitude and Airspeed are fundamental to the control of the aircraft during flight. Monitoring Weather Conditions is crucial for planning and executing a safe flight path, while Aircraft Identification is important for air traffic control and in the case of any investigations following incidents or accidents. Checklists, like those developed by the World Health Organization (WHO) for surgical safety, serve in aviation and space exploration to systematically verify that equipment is functioning and safety protocols are followed.
