![]() ![]() Aviation remains one of the few places that the slide rule is still in widespread use. Extra marks and windows facilitate calculations specifically needed in aviation.Įlectronic versions are also produced, resembling calculators, rather than manual slide rules. One side is used for wind triangle calculations using a rotating scale and a sliding panel. Construction įlight computers are usually made out of aluminum, plastic or cardboard, or combinations of these materials. They are frequently referred to by the nickname "whiz wheel". The back is designed for wind vector solutions, i.e., determining how much the wind is affecting one's speed and course. In the air, the flight computer can be used to calculate ground speed, estimated fuel burn and updated estimated time of arrival. These flight computers are used during flight planning (on the ground before takeoff) to aid in calculating fuel burn, wind correction, time en route, and other items. They are mostly used in flight training, because these flight computers have been replaced with electronic planning tools or software and websites that make these calculations for the pilots. ![]() But even still there's no possibility for a valid answer for the question.An E6B flight computer commonly used by student pilots. The only way I can think to make this situation possible is that maybe you've tuned the world's most bizarre VOT. But the question removes that possibility. ![]() If it's still indicating the same radial after non-parallel movement, the only option is that the indicator is in error. If the airplane doesn't parallel a radial, and yet it moves, the radial it's on must change. With a groundspeed of 120 knots and a constant ground track, after 10 minutes the airplane will have moved 20 miles in a straight line. Would my understanding of the situation be correct?īad news: the question is unanswerable. To my understanding the heading indicates the direction the aircraft is pointing in is 120 degrees with respect to magnetic North however its course must be either be 30 degrees with respect to magnetic North or 210 degrees with respect to magnetic North, allowing it to stay in the station's 30 degree radial. I'm not quite positive of my understanding of the situation. At time t(2), 10 minutes later than t(1), the VOR receiver indicates that the aircraft is on the 30deg radial from the same station.Īssuming no errors, what is the pilot’s distance from the VOR station at time t(2) ? If the pilot had access to airspeed, can the range be determined from the VOR measurements? Can it be determined if the pilot had access to ground speed and ground track heading? The pilot maintains a ground track heading of 120deg with respect to magnetic North and 120 knots ground speed. The question goes like so:Īt time t(1) an airborne VOR receiver shows that the aircraft is on the 30deg radial from a VOR station. During the 10 minutes between T(1) and T(2) the aircraft maintains a heading of 120 degrees from magnetic north at 120 knots ground speed. The aircraft is found in the 30 degree radial from the VOR station at time T(1) and T(2). I am currently struggling to understand the following question regarding a VOR station and an aircraft. ![]()
