... No, I guess I overstated it. I do know both mileage and expected flight time - but usually just for the whole route, not for multiple waypoints enroute. Then how do you know what your actual groundspeed is? Oh, right...I forgot...you trust your GPS completely to tell you this. And of course, you will never be without your GPS. [...] That's ridiculous. I fly 150 kts TAS. Give me the distance to the destination, and 20 seconds, and I'll tell you the enroute time within 10%. During the weather briefing (which I never skip - I have a lot of respect for weather) I may adjust that for winds. Once again - easily done in my head. Then why did you suggest you don't do that part of the planning? You are now asserting that you do. I never said the planning should be HARD. I simply said it should be done. [...] So what do you do - the fan stops, and instead of looking out the window for a landing spot you start referencing your charts. Ridiculous. That's right, it would be ridiculous to do it that way. I never said I did. The point is that having properly planned the flight, and properly navigating along the route of the flight, you know at all times where you're going to land. If "the fan stops", you simply land where you planned to. Sectionals give very broad altitude and terrain information. I guess that depends on your definition of "broad". I find sectionals to be quite detailed in their depiction of altitude and terrain information (whatever the difference between the two might be...not sure why you use two different words to describe basically the same information). Using a sectional, I can plan a flight through a canyon just a few miles wide, and be completely assured of terrain avoidance, and of being able to correlate the chart with the visual recognition of the terrain while enroute. Sectionals certainly have FAR more detailed terrain elevation data than any GPS I've seen. There is no way you will have time during a true emergency to use them or your preflight planning of emergency landing spots. You will look down, pick a spot, and follow the emergency checklist. IMHO, if you are picking the landing spot after the emergency commences, you have failed in your duty as pilot in command. This is whether you've done any flight planning or not. [...] Which I know by looking out the window. Some things are obvious. I live in Colorado. I don't fly west over the Rockies in IMC or at night. I avoid open water. I don't need VFR sectional charts for this stuff. The midwest is flat. The plains are rolling. The desert is harsh. The mountains are pointy. Minnesota has trees everywhere. You really don't need a sectional to know this stuff. I feel pity for a pilot who thinks those kinds of generalities suffice for the purpose of understanding the effects of terrain and man-made objects on the flight. You need to understand what sort of emergency landing sites are available. You need to know how the terrain will affect the winds aloft. You need to know whether you are flying over densely or sparsely populated areas. You need to know whether your route takes you along a major highway, or far away from any services. Once again, I know all this stuff without sectionals. You can't possibly, not without some other reference that is basically identical to a sectional. [...] I think this is a big difference between us. I don't consider this a distraction in the air. It is as simple as setting the pitch or mixture. I do it all the time. No, it doesn't sound like you do. Not really. There's a big difference between punching a new airport ID into a GPS, and coming up with a *plan*. Though, admittedly, in your case perhaps there is no difference, since your plan never seems to go beyond that anyway. [...] You seem to think if I don't have waypoints and sectionals all laid out in advance I won't know where I am or what my fuel situation is. I know both all the time when I am in the air. And, as an aside, not that I'd ever let myself get to that point, but you would be hard pressed to ever be further than one hour from fuel flying in 90% of the US. Well, first of all, I already pointed out that you really need to be closer than one hour to the nearest fuel. But even so, I find myself an hour from the nearest fuel on a reasonably regular basis. It's not hard, flying around the west. Checking waypoints during the flight provides you with nearly fool-proof (subject only to your own computational skills) information regarding your fuel status. Yes, other resources provide that information as well, but cross-checking is always good. Reliance on fewer sources of information than are available is bad. Well then, by your reasoning you should be using ded-reckoning (or however that is spelled) as well. How so? Dead-reckoning is not nearly as reliable as pilotage. It's basically a "poor man's intertial navigation system". With pilotage, you know exactly where you are. All dead-reckoning does is give you a rough guess as to where you think you might be. There is NOTHING more reliable than seeing out the window of the airplane and knowing with 100% certainty how the picture out the window matches the image on your chart. Nothing. [...] Pre-flight planning allows you to contact an FBO on the phone prior to flight. This is a good thing to do at the very least for a planned fuel stop, and should probably be done for possible alternates as well. You can't even do it for the planned fuel stop, unless you actually HAVE a planned fuel stop before you get into the airplane. You really do this - you call the FBO to make sure they have fuel before you take off? Yes, of course I do. I verify that they have fuel, their hours of operation, their methods of payment, and if they have pilots on staff around when I call, I'll even ask about any "local knowledge" that might be useful to a transient pilot with respect to my arrival and subsequent departure. It's not even that hard to find stories of pilots who have arrived at an airport, expecting to take on fuel, only to discover some problem. Of course, even calling ahead isn't fail-safe. For example, on a recent flight from Medford, OR to Fort Collins, CO, I stopped for fuel in Idaho. I had called ahead to make sure they had fuel and were going to be there, but when I arrived, they had some sort of technical issue with their credit-card system. We worked something out, but had they known of the problem before I took off, I probably would have landed somewhere else. I'm amazed. Never occurred to me. That's like calling a restaurant and asking them if they have food before you come in for dinner. It's more like calling a restaurant and asking them if they have food before you come in for dinner, if you are going to expire from hunger if no food is available there. In reality, your analogy sucks because a) food is almost never a critical resource for survival for folks like us, and b) if there's one restaurant, there is almost always another across the street. With fuel, especially when flying at the limits of endurance for one's aircraft, or when flying in very sparsely settled areas such as exist here in the west, you may only get one chance for fuel, especially if you apply the kind of "planning" to your flight that you apparently do. [...] How do you know the navigation was accurate, unless you were cross-checking? I never said I don't cross check the navigation aids. I said I don't plan the waypoints on the ground. I fly over a town, I'll dial in the GPS and see what town it is. How do you know the GPS is telling you the correct information? I can cross check highways, rivers, airports, runways, VORs, NDBs, intersections. All easily done in the air. Again, how do you know the GPS is telling you the correct information? In any case, your argument relies heavily on the Garmin 430 GPS you have installed. Your original question said NOTHING about the kind of equipment one might be using, and as common as GPS is becoming, nice moving map GPS receivers such as the 430 are hardly ubiquitous. Even if I had a 430 in my plane, I would plan my flights with more detail than you do. But I hardly think it's useful for you to equivocate on your original question by bringing in new elements to it. If you had asked "does anyone with a 430 still plan their flights?" I would not have even bothered to answer. Pete |

When I fly over canyons I'm looking at emergency landing spots far to either side of them. Maybe this accounts for some of the difference in our approach.

In any case, I appreciate it - you have some interesting points. I don't agree with them, but they are interesting. Michael |

[...] Frankly, if it weren't for your already reasonable reputation around here, it's at this point that I'd accuse you of being a troll. So far, practically every aspect of your argument against flight planning relies on equipment that is simply not available to most pilots, 100 hour or not. You're flying with an IFR certified GPS receiver in the oxygen levels, and that seems to be the core justification behind your failure to do detailed flight planning. Yet, your original post clearly implies that the difference between a person who spends time flight planning and one who does not is simply pilot time. Well, you sure stirred things up good. You deserve the benefit of the doubt, and I'll assume it wasn't intentional. But you could not possibly have lead off with a more misleading question if you'd done it on purpose. Pete |

Watch the landscape and ignore time and distance, and you will get stung. Even a rough calc will help keep you out of trouble. Lesson 1 in pilotage is see the feature, then find it on the map ..... and after you master that along with lessons 2,3,etc Lesson 10 is complement your pilotage with some rough dead reckoning or you will end up relearning lesson 1 the hard way. Does that make any sense? |

Well Matt,I'd agree and disagree...
I'd agree that the area you fly in is some of the most distinctive in the country, at least to these eyes. Though I don't think that applies to a Western pilot flying there for the first time - it all looks the same to the inexperienced eye... Which is where I'd disagree that the terrain makes the difference. Unknowingness, a state you've probably not been in for awhile, is *the* difference. Most of my time is in the same district. Starting in 1970 at Pgh's AGC, buzzing around central NJ, then doing the the glider circuit from 82 to 97 starting at Sugarbush VT, Elmira, Danville NY, Blairstown NJ, Middletown NY, Candlewood Lake CT, Solberg NJ, New Castle VA, Fairfield PA, Chester NC, Mifflin PA, and practically every inch of the ridge system from Wurtzboro NY to Lock Haven to Burnt Cabins to New Castle to the Masanuttin (sp). I flew all of the above using pilotage and charts and often at ridgetop height. Preparation and 'knowingness' made dead reckon unnecessary (though I got lost anyway in the early days). So I agree with your point, up to a point. But I also went out to Hobbs NM, and Minden NV and Marfa TX, and Caddo Mills TX, and Bozeman MT and Uvalde TX and Ionia MI and even Homestead FL. At every site I had the chance to fly 5 to 10 cross countries in a 100 to 150 mile radius of the site. None of them are featureless mid-western sites, at least to the locals. I was totally challenged to follow my progress via pilotage - but I did have GPS so all my observations are suspect. But it really came into focus when I flew one of my last contests in Mifflin PA. It attracted a bunch of guys from the left coast who were flying in the NE for the first time. Their discomfort with both flying and navigating the terrain was obvious and it effected their performance enormously - for a couple of days anyway. So, I would suggest that your familiarity with the 500 miles surrounding northern PA makes pilotage a breeze, especially at 4000' or better. But fly in the very distinctive terrain around Reno NV or Austin TX for the first time, and you might find your pilotage skills totally challenged, even at 10,000'. And you might discover why a little dead reckoning for backup might prove an ego saver. Mark Twain wrote about our enormous ability to remember the details of our environment in "Life on the Mississippi". As I recall, he talked about how a river captain's job depended on his recall of every snag, shoal, turn, wreck, and current in the ever changing river - 100s of miles worth of detail. "Knowingness' may be one of our core competencies as humans. Good book and a good read for pilots. Matt Whiting wrote: Maule Driver wrote: Matt Whiting wrote: Dylan Smith wrote: How so?
