How are approach charts integrated into the Longitude 700's navigation and decision making?

• A. Follow approach in the FMS or on the primary flight display; verify fixes, altitudes, and constraints; cross-check with chart data.
• B. Ignore charts and rely on memory.
• C. Print charts only; do not reference them during flight.
• D. Approach charts are not used.

Answer: (A)

Loading and using approach charts inside the Longitude 700 means the FMS/flight deck displays the published procedure as part of everyday navigation. The approach is loaded into the FMS, and the navigation displays show the sequence of legs, fixes, and the published altitude constraints or step-downs. The autopilot or flight director can fly the route, while you continuously verify that the lateral path and vertical profile shown on the PFD/MFD match the chart. This keeps what you’re actually flying in line with the published procedure and makes it possible to recognize any mismatch quickly.

Cross-checking with chart data is essential because it confirms that the numbers you’re seeing—course, distances, altitudes, and step-downs—are correct for the exact procedure and runway. It also supports sound decision making: you can confirm when to descend, where to expect a hold or procedure turn, and what the minimums are for landing versus going around. Relying on the chart data in the cockpit rather than memory or separate printouts reduces errors and enhances situational awareness during approach.

In practice, you follow the approach path shown by the onboard guidance, while continuously verifying it against the published chart data and any ATC instructions, ensuring a safe and compliant approach.
