Instrument Oral Exam Questions 111-150 Questions and Answers | Latest Version | 2024/2025 | Rated A+ Why is it important to cross-check instruments during flight? Cross-checking ensures data accuracy and helps detect any malfunction or discrepancy in instrument readings. Describe the purpose of a turn coordinator. The turn coordinator shows the rate of turn and coordination, indicating whether a turn is balanced or if there is any skidding or slipping. What information does a heading indicator provide that is essential for instrument flight? The heading indicator shows the aircraft's current heading relative to magnetic north, aiding in accurate navigation. Explain how the magnetic compass can be affected during flight. The magnetic compass is affected by magnetic variation, deviation, and acceleration errors, especially during turns, climbs, or descents. 2 What is the function of the altimeter in instrument flight? The altimeter measures the aircraft's altitude above sea level, essential for maintaining assigned flight levels and terrain clearance. How does a pilot use the approach plate during an approach? The approach plate provides critical information such as navigation frequencies, course guidance, and minimum descent altitudes for safe approach to the runway. What does an instrument approach procedure (IAP) help with? An IAP guides the aircraft safely to the runway when visibility is limited, using predefined navigation and altitude steps. Describe what a missed approach procedure is. A missed approach procedure is followed if landing cannot be completed, instructing the pilot on how to safely leave the approach path. What is the purpose of the glide slope in an ILS approach? 3 The glide slope provides vertical guidance, helping the aircraft descend on the correct angle towards the runway during an ILS approach. How does DME (Distance Measuring Equipment) assist in instrument navigation? DME provides the distance between the aircraft and a ground station, aiding in position determination and timing for approach segments.
