  • Chapter 16: Navigation › Effect of Wind

    determining the amount of drift, the pilot can counteract the effect of the wind and make the track of the aircraft coincide with the desired course. If the mass of air is moving across the course from the left ... aircraft drifts to the right, and a correction must be made by heading the aircraft sufficiently to the left to offset this drift. In other words, if the wind is from the left, the correction is made by pointing…

  • Chapter 11: Helicopter Emergencies and Hazards › VFR Flight into Instrument Meteorological Conditions

    Heading and Trim – pick a heading known to be free of obstacles and maintain it. This will likely be the heading you were already on, which was planned and briefed. Set the heading bug, if installed, to avoid overcontrolling your ... airspeed. Each encounter with UIMC is unique, and no single procedure can ensure a safe outcome. Considerations in determining the best course of action upon encountering UIMC should include, at a minimum, terrain, obstructions, freezing levels, aircraft performance and limitations…

  • Chapter 16: Navigation › Pilotage

    flight planning is a plotter, which is a protractor and ruler. The pilot can use this when determining TC and measuring distance. Most plotters have a ruler that measures in both NM and SM and has a scale ... navigation by reference to landmarks or checkpoints. It is a method of navigation that can be used on any course that has adequate checkpoints, but it is more commonly used in conjunction with dead reckoning and VFR radio navigation…

  • Chapter 16: Navigation › Charting the Course › Steps in Charting the Course

    part 91 requirement to fly at an altitude of odd thousand plus 500 feet when on a magnetic course between 0 and 179°. Next, the pilot should measure the total distance of the course, as well as the distance between ... distance between checkpoints is as noted on the flight log in Figure 16-26. After determining the distance, the TC should be measured. If using a plotter, follow the directions on the plotter. The TC is 031°. Once…

  • Chapter 16: Navigation › Dead Reckoning › Wind Triangle or Vector Analysis

    computations based on time, airspeed, distance, and direction. The products derived from these variables, when adjusted by wind speed and velocity, are heading and GS. The predicted heading takes the aircraft along the intended path and the GS establishes ... destination. Except for flights over water, dead reckoning is usually used with pilotage for cross-country flying. The heading and GS, as calculated, is constantly monitored and corrected by pilotage as observed from checkpoints. Wind Triangle or Vector Analysis…

  • Chapter 16: Navigation › Dead Reckoning › Step 4

    compass heading can be used to fly to the destination by dead reckoning. To determine the time and fuel required for the flight, first find the distance to your destination by measuring the length of the course line drawn ... consumption is 8 gallons an hour, 8 × 2.5 or about 20 gallons is used. Figure 16-22. Finding true heading by the wind correction angle. Figure 16-23. Finding true heading by direct measurement. Briefly summarized, the steps in obtaining…
