Temporal Fix-to-Fix Exercise #1, Part 1 of 2 - Set Up
1) Go to SIM Program
http://wantscheck.com/UPTPrep/CourseInterceptTAid/tabid/380/Default.aspx
2) (your target fix is the 090 degree radial at 15NM) Dial the course arrow to 090.
3) locate (drag and drop) your aircraft to the lower right corner of the screen, somewhere near the 130degree radial @ 18NM (leave your aircraft pointed in the direction of N/360 degrees)
4) Hit the Pause/Freeze Button. . . Now let's take a look at your situation, and visualize the rules below while you sit frozen on Pause. (I know much of these rules & observations will seem obvious, but no matter how experienced you are, you need to focus on these points for this to work. . Don't skim over this. . If an IP were teaching you this, he'd drag you through this logic to prepare your thought process, then quiz you on it to reinforce it. . So don't skip it.This is the heart of the technique.. Programming your mind to interpret
MOVING instrument indicators.)
Rules and Observations . . . * Your aircraft is now somewhere south of the fix, headed somewhat north (but unlike conventional navigation methods, you don't care exactly where you are, or exactly where you are going, or exactly what your heading is. You're not going to calculate a course, a heading, or even spend a lot of time looking at numbers. . And you couldn't care less about crosswinds. , , ,
Bearing Pointer Basics - * Note that your bearing pointer is pointed to the upper left corner of your HSI, towards the TACAN/VOR station. . (but unlike conventional navigation methods, you don't care what the bearing is, or anything else related to numbers. . You're just going to keep your eye on the bearing pointer's physical movement as you fly. . Not its bearings, just its physical movement.) . . * Note that the tail of your Course Arrow sits opposite the 090 radial you dialed into the Course Window, at 270 on the dial. . ( But unlike conventional navigation methods, you don't care about the number 270 itself, you're just going to note the physical location of the tail of the Course Arrow tail on the bevel, that's all.) . * When we resume flight, we should notice that the
Bearing Pointer will FALL as we fly North towards the 090 radial. . When the bearing pointer reaches the tail of the Course Arrow, we've crossed the 090 target radial. . * We should anticipate that the speed at which the
Bearing Pointer falls towards the wingtip will
Speed Up as it Falls. Why won't it fall at the same speed all the time? . Answer: Because radials get closer together in a polar coordinate grid as we fly closer to the TACAN/VOR (study a polar coordinate grid diagram to understand why. . .
http://www.waterproofpaper.com/graph-paper/polar-graph-paper.pdf . .) . So the BP will always be
Speeding Up when it is above the wingtip. After the
PB falls below the wingtip, it will
Slow Down. Why won't the BP fall at the same speed all the time? Answer: Because the radials get further apart as we fly away from the TACAN/VOR station (study a polar coordinate grid diagram to understand why). . So the BP will always be
Slowing Down when it is below the wingtip. .
DME Basics * . The DME
Slows Down when the BP is falling toward the wingtip. As you fly past the TACAN/VOR (BP on wingtip), the
DME stops, and then it reverses direction. . * The DME
Speeds Up when the BP is falling toward the tail of the aircraft. . Why? . Answer: (think this thru and try to answer it for yourself) * When you turn the aircraft, you affect both BP and DME speed, with equal but opposite effect (in other words, one speeds up while the other slows down) . Why?. Answer: (think this thru and try to answer it for yourself)
Tip:: The Rules and Observations above are the core of your guiding principles. . Thorough familiarity with them is the key to acquiring the Temporal Perception you will need to interpret and utilize the HSI with extraordinary efficiency. .
Experienced, proficient pilots subconsciously absorb these (and other) dynamic principles after years of "experience." . But they usually don't ever consciously realize it, or the significance of it. And even if they do sense it, they don't know how to break it down and explain it to an inexperienced student.. Pilots who burn these dynamic principles into
conscious memory turn into what appear to be Savants to un-initiated pilots.. What might take another pilot a lifetime of
subconsciously accumulated dynamic "experience" can be packed into a 1 Hour, one-on-one conscious memory programming session. . Your task here is to quickly cram years of HSI motion dynamics "experience" into your brain. . Since I can't talk you thru it, do it yourself. . Quiz yourself on these simple observations, rules and principles until they are easy and natural to recall.
- Rules of the HSI summarized- a) The BP always falls b) The BP speeds up when it is above the wingtip c) The BP slows down when it is below the wingtip d) DME decreases when the BP is above the wingtip e) DME increases when the BP is below the wingtip f) DME slows down when the BP is above the wingtip g) DME speeds up when the BP is below the wingtip h) when you turn the aircraft, you affect both BP and DME speed, with equal but opposite effect (in other words, one speeds up while the other slows down) . .
(Notice that I'm unconcerned with numbers, bearings or headings. I'm only interested in words like "falling"," increasing", "decreasing", "speeding up," and "slowing down." . That's all you should be thinking about. . I care about
qualitative values, not
quantitative values. .
Qualitative values of time and motion are the input data your brain needs to process Temporal calculations. Don't think about numbers. Numbers inhibit Temporal Perception and processing. . You'll be using a different part of your brain for this fix-to-fix. . This is left brain vs right brain stuff.)
- Why these Rules are so Important - You are being asked to disregard everything you know about navigation.. You are being asked to toss away numbers, bearings, courses, headings, and geometry, and focus instead on inputs containing no hard data.. That might be easy for a new unrated student to accept from a respected IP, but its pretty hard to swallow for an experienced navigator. So what happened to the hard mathematical data you need to navigate.? The Answer:: It's still there, hidden in the
MOTION of the instrument indications.. We don't have the time or the space here for me to provide you with the mathematical conversion analysis. That would take several pages of trig and calculus. But here is a plain language summary::
The math is built in and hidden in the motion of the HSI's indicators. Therefore, the HSI's indicators (BP and DME) MOVE at a rate which is commensurate with, and indicative of, the aircraft's Position, Direction, and Velocity thru the polar coordinate grid. . In other words, the needed quantitative math & geometric data is converted to qualitative motion data (Something like converting digital signals to analog signals, or 1s and 0s to wave forms, for those of you familiar with that concept.). So the mathematical data is still there, its just read and processed differently. Qualitative Motion data can be read and processed using a subconscious ability known as Temporal Perception. Math data, in contrast, is generally processed using conscious functions in a different part of the brain.. By shifting the calculations to the subconscious part of the brain (using temporal conversion inputs that this brain section can understand) , pilot overload is relieved.
- What is Temporal Perception? - . Temporal/Time perception is essential for survival.. From merging into lanes on a freeway of moving traffic, to entering a full traffic pattern. You have lots of internal clocks running in your brain right now.. One internal clock will bug you to go to work, even if you have not looked at a clock for a while. Another may wake you up even if your alarm clock fails.. There's another clock that will remind you that you left a pot of soup heating on the stove, that you need to stop reading this, and go check the pot.. Temporal Perception is a primary human ability with very accurate and sophisticated processing capability. And most of it takes place subconsciously.. Most pilots have better than average temporal abilities, but they don't consciously think about it, they don't try to develop or enhance it, and thus they don't utilize it to maximum effect. We take this ability for granted, and we don’t consciously think to harness it to navigate an aircraft.. But you can harness it with practice, because your instrument indicators
MOVE.. In fact, experienced pilots do use it unknowingly for many tasks, including navigation, even if they don't realize it.. Developing the ability can intensify its performance value.. The benefits are enormous for an already overloaded pilot, or one who wants to speed up and increase his ability to process information.
- What is the Advantage (to a pilot) of Converting Quantitative Navigational Data to Qualitative Motion Data?. Your brain is the most important computer processor in the aircraft.. It has to divide its time between tasks.. If it gets overloaded, performance suffers, fatigue can set in.. Mistakes happen.. Safety is compromised.. Too bad you can't reassign your navigational duties to a different processor.. Your brain isn't a dual core Intel chip.. Or is it?. If you could harness an unused part of your brain to take over your navigation inputs and processing duties, that would leave the currently active part of your brain with more time to attend to other tasks (like aircraft control, cockpit checklists, and radio transmissions).. Well, it turns out you do have unused brain sections, but they don't all function using the same data inputs. The Moody AFB IPs stumbled onto a method of re-assigning their navigation processing to an unused portion of the brain, the Temporal processing portion (believed to be in the basal ganglia and the parietal lobe).. By inputting qualitative motion data into the part of your brain that processes Temporal Data, your navigation tasks can be processed in an underutilized but amazingly efficient part of the brain.. And since the fix-to-fix navigation math is secretly buried within the BP/DME motion (including winds), its all calculated for you, subconsciously.. (Something like digital to analog conversion, and back again.)
