Figure 16-26.  Pilot’s planning sheet and visual flight log.  The formula is:  part of a series of antennas with a height of 2,749 feet MSL  (point D). The highest elevation should be located in the  northeast quadrant and is 2,900 feet MSL (point E).  Since the wind is no factor and it is desirable and within the  aircraft’s capability to fly above the Class C and D airspace  to be encountered, an altitude of 5,500 feet MSL is chosen.  This altitude also gives adequate clearance of all obstructions,  as well as conforms to the 14 CFR part 91 requirement to  fly at an altitude of odd thousand plus 500 feet when on a  magnetic course between 0 and 179°.  The WCA can be determined by using a manual or electronic  flight computer. Using a wind of 360° at 10 knots, it is  determined the WCA is 3° left. This is subtracted from the  TC making the TH 28°. Next, the pilot should locate the  isogonic line closest to the route of the flight to determine  variation.  Figure 16-25  shows the variation to be 6.30° E  (rounded to 7° E), which means it should be subtracted from  the TH, giving an MH of 21°. Next, add 2° to the MH for  the deviation correction. This gives the pilot the compass  heading of 23°.  Next, the pilot should measure the total distance of the  course, as well as the distance between checkpoints. The total  distance is 53 NM, and the 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 the TH is established, the pilot can determine  the compass heading. This is done by following the formula  given earlier in this chapter.  Now, the GS can be determined. This is done using a manual  or electronic calculator. The GS is determined to be 106  knots. Based on this information, the total trip time, as well  as time between checkpoints, and the fuel burned can be  determined. These numbers can be calculated by using a  manual or electronic calculator.
