Results for different descent speeds, and for descents involving decelerations or accelerations in speed. Additional calculator accuracy is achieved by proportioning the altitude scales for each aircraft speed in terms of mach speed above predetermined transition altitudes, and in terms of indicated air speed below the transition altitudes. the transition altitude for each aircraft speed is equal to that altitude above which mach speed exceeds indicated air speed, and below which indicated air speed exceeds mach speed. the descent gradient (or altitude loss/mileage ratio) for any particular idle descent varies at different altitude ranges, primarily because of the mach-indicated air speed cross-over, and to a lesser degree because of changes in air density and true air speed as altitude changes. Accuracy in this regard is achieved in the present invention by making a single distance scale linear and a plurality of the altitude scales variable to reflect accurately the proper altitude/mileage ratio for a particular altitude segment and aircraft speed. Furthermore, the various altitude scales extend over approximately equal altitude ranges.

Useful for descents which involve a deceleration from one speed to a lower speed. the pilot would use the altitude and distance of the deceleration point as his first target, and use the calculator to determine the distance for beginning a high speed descent to that point along the distance corresponding to the higher speed. the pilot can reset the calculator so that the ultimate target distance on the lower speed distance scale is aligned with the ultimate target altitude, and read the distance corresponding to the present altitude. a wind/weight correction factor would then be determined as described above. Extra distance necessary to decelerate can also be accounted for. the target altitude of 13,000 feet would be aligned with 32 miles on the 280 knot distance scale, rather than 30 miles. the calculator is in the general form of a circular slide rule mounted on a center card member 22. a plurality of circular disk members 24, 26 and 28 of progressively decreasing diameter are stack mounted on one side of card 22, and a similar plurality of disk members 30, 32 and 34 of progressively decreasing diameter are stack mounted on the opposite side of card 22. a pin 36 extending through card 22 and the centers of the various disks secures the disks to the card, whereby each of the disks can be rotated relative to the card and to the other disks. a pair of cursor elements 38 and 40 are also secured over the outermost disks on each side of the card to assist in reading the information provided by the calculator.

Savings, is calculated by subtracting 3.5 from the mileage otherwise indicated by the calculator for beginning the descent. The calculator is also very useful in monitoring the aircraft's adherence to a fuel efficient descent profile once the descent had begun. The pilot keeps stick 16 in place with the target altitude aligned with the target distance, and reads the calculated distance corresponding to any given altitude during the descent. This calculated distance is corrected by a net wind and weight correction factor for the particular altitude, to tell the pilot whether he is at the correct distance for the given altitude. The calculator is particularly useful for descents which involve a deceleration from one speed to a lower speed. The pilot would use the altitude and distance of the deceleration point as his first target, and use the calculator to determine the distance for beginning a high speed descent to that point along the distance corresponding to the higher speed. When that point is reached, the pilot can reset the calculator so that the ultimate target distance on the lower speed distance scale is aligned with the ultimate target altitude, and read the distance corresponding to the present altitude. A wind/weight correction factor would then be determined as described above. Extra distance necessary to decelerate can also be accounted for. In the example described above, assuming the aircraft was required to be slowed to 250 knots at 13,000 feet and 30 miles DME from an initial speed of 280 knots, and that a deceleration distance of two miles was required, the target altitude of 13,000 feet would be aligned with 32 miles on the 280 knot distance scale, rather than 30 miles. Referring now to FIGS. 4 and 5, a second embodiment of the invention is shown which offers several
