Question

Which of the following sensors could be used to detect if an airplane is flying in cruise mode (horizontally), or if it is taking off or landing? (select 2):

A. A tilt sensor
B. A 3-axis accelerometer
C. A 3-axis gyroscope
D. A radar
E. A 3-axis magnetometer

Answer 1

The 3-axis accelerometer and radar sensors can be used to detect the airplane's mode of flight.

Step-by-step explanation:

The sensors that could be used to detect if an airplane is flying in cruise mode or if it is taking off or landing are:

1. A 3-axis accelerometer: Measures the acceleration forces acting on the airplane in all three axes, which can indicate changes in speed or direction that occur during takeoff or landing.
2. A radar: Can detect the altitude and speed of an airplane, allowing for identification of whether it is in cruise mode or in the process of taking off or landing.

These sensors provide important data to pilots and air traffic controllers to ensure safe and efficient operations.
