Full scale is also a term that defines how much an output can rise or fall to i.e. On most localizer courses, full deflection indicates 2.5 degrees. Now if we dig into order 6750-16E which lays out the spec for designing ILS systems we can see that the all CDI's must be calibrated to 150 micro amps equals a full deflection and likewise this needs to be calibrated to the edge of the ILS course (bolded for emphasis), c. Localizer Receiving Equipment. An aircraft which is located 30 miles from a VOR station and shows a 1/2 scale deflection on the CDI would be how far from the selected course cenerline? FSD is the maximum deflection the needle moved and, this represents the "full scale". The standard or approach mode armed, the approach mode will switch to active, which Why xargs does not process the last argument? (Refer to Figures 98 and 99) To which aircraft position does HSI presentation "B" correspond? What does 'They're at four. Short story about swapping bodies as a job; the person who hires the main character misuses his body. Is "I didn't think it was serious" usually a good defence against "duty to rescue"?
