Explain how pilotage and dead reckoning can be used together on a Visual Flight Rules (VFR) flight.

### Why this is right The two methods serve complementary roles: dead reckoning predicts where the aircraft should be, while pilotage uses visible features to check and refine that estimate. Wind correction is needed because the planned heading, distance, and time can be affected by wind. ### The concept Pilotage means navigating by recognizing landmarks such as towns, rivers, highways, and shorelines. Dead reckoning means estimating progress from planned direction, distance, speed, and elapsed time. Before flight, a pilot can mark checkpoints on a chart and calculate the headings and times for each leg. During flight, visual confirmation at a checkpoint helps reveal whether the estimate is consistent with the aircraft’s actual location. Neither method removes the need to plan for changing conditions. ### What a good answer covers - Pilotage uses visible ground features. - Dead reckoning plans headings, distances, and times between checkpoints. - Wind can change the planned values, so corrections are needed. - Visual observations can check the estimated position. ### Terms - **Visual Flight Rules (VFR)**: rules for flight that rely on visual references and applicable visibility conditions. - **Dead reckoning**: estimating position and progress from a known starting point, direction, distance, speed, and elapsed time. - **Checkpoint**: a planned or recognizable position used to monitor route progress. ### Remember Dead reckoning predicts; pilotage checks against what you can see.
