Answer:
The correct answer is:
b) Navigation radio, vertical speed, airspeed, and lateral deviation.
Step-by-step explanation:
The Course Deviation Pointer (CDI) is an instrument used in aircraft to indicate the deviation of the aircraft's actual track from a desired course. It's typically associated with navigation systems such as VOR (VHF Omnidirectional Range) or GPS (Global Positioning System).
The four inputs that can slave the Course Deviation Pointer (CDI) are:
1. **Navigation radio:** This input provides information about the selected navigation source, such as VOR or GPS, and the desired course to be followed.
2. **Vertical speed:** Vertical speed refers to the rate at which the aircraft is climbing or descending. It's one of the parameters used to determine the aircraft's performance in the vertical dimension.
3. **Airspeed:** Airspeed indicates the speed of the aircraft through the air. It's crucial for determining the aircraft's performance in terms of speed and stability.
4. **Lateral deviation:** Lateral deviation refers to the degree to which the aircraft's actual track differs from the desired course. It's the primary parameter that the CDI displays, showing whether the aircraft needs to adjust its heading to stay on course.
These inputs work together to provide pilots with essential information about their navigation and flight performance, allowing them to make necessary adjustments to maintain their desired course and altitude.
