I also agree with you completely and would like to encourage others to continue posting their errors so that we can all learn. I have certainly made my share of errors in my 1500 hours, and have posted many of them here. If someone wants to remain anonymous, they should feel free to do so. Best, Cary |

Last time I checked celestial navigation wasn't in the PP requirements and use of a VOR was. When did you last check? "VOR" does not appear in Part 61. You're such a dick Steven. Does the initial P stand for penis? I believe your response to a civil question imminently qualifies you for the invective you so glibly sling, more than the object of your scorn. Mr Netkkkop speaks out again. Bertie |

There are lots of times that GPS, VOR and even ADF are the primary navigation aids for VFR pilots. Well, there are other, more traditional, methods that are really pretty essential if you're going to do that. 1 in 60 rule, for instance. Determinging drift from aircraft ref points and celestial bodies, that sort of stuff. Bertie Last time I checked celestial navigation wasn't in the PP requirements and use of a VOR was. I know, but going vfr on top is kinda heavy territory for someone with a fresh ppl anyway. How many know the 1/60 rule? Bertie I didn't say anything about someone with a fresh PPL. The person I was responding to (a student) was saying that a non-instrument rated pilot shouldn't be using GPS, IFR... as primary navigation. I've heard the term 1/60 rule but don't know what it is. Well, what I'm advocating is a bit more nuts and bolts nav sense if people are going to start dicing with weather, rather than just rely on GPS, so I think we're on the same page. The one in sixty rule just means, for example, that every sixty miles you are from a navaid, each degree is about one mile. So, if you're sailing along roughly abeam a VOR with no DME, and you know your groundspeed is about 2 miles a minute and you cover two degrees in about a minute, well, you know that that VOR is sixty miles away. If you cover four degrees in a minute, you're thirty miles and so on. It's rule of thumb, but it works well. Likelyise, if you are dead reckoning on top and there is one quick visual reference and you know how far it is off your dsired track since our last known position, you can calculate your drift quite accurately for your next leg. There's a thousand and one uses for it. Cool eh? Bertie |

Luckily google yields this: http://en.wikipedia.org/wiki/1_in_60_rule It's not widely taught these day, along with a host of other nav tricks that were common knowledge years ago in pre radio days. This one is one of the most useful i can think of though. Another example would be if you are flying along an airway and there's a navaid roughly abeam you you can figure your groundspeed by counting the time it takes to cross radials. One other simple nav trick is to be aware of how many degrees a particular point of your airplane is form your eye position. To make this as accurate as possible, you have to start out with standard position for your eye, i.e, make sure you make the observation from the same positon and not with your seat slid forward one time and back the next. Then measure, using wahtever sort of device is to hand, the point of your aircraft that would be 5 deg left of the aircraft's centerline. You could move the airplane around on the ground to do this using a distant ground refernce point, or you could use a homemade sextant or whatever way you care to come up with. You can do it on cowl parts, wings, and tail. The fore and aft ones are most useful, but it's handy to have some reference on the wings as well. When you know the references, you can easily calculate your drift by seing whcih refernce line remains steady with a ground refernce as you fly along. The poiint that remains steady on your aircraft is indicating your drift. This is especially handy if you're leaving your last ground ref points behind you like on an overwater flight. You can get an actual drift by looking behind you as you head away from land. A lot of old time long distance flyers would have had lines painted on various parts for this very purpose, especially on the stab. I think the Douglas world Cruisers had them, for instance, and a lot of the Benidix and McPherson racers would have had them. Bertie |

Demonstrates the ability to use an airborne electronic navigation system. 3. Locates the airplane's position using the navigation system. 4. Intercepts and tracks a given course, radial or bearing, as appropriate. It doesn't refer to any specific system. The requirements can be satisfied with ADF. Which is one of the systems I mentioned to start off with. But when I took my PPL test ride ADF and GPS weren't options so I shortened it. |
