dead reckoning IFR
Ok so, my last question on non-radar IFR procedure made me curious. I would probably never use it, but I had a CFII tell me that dead reckoning can be used as a suitable means of navigation for IFR.
Perhaps that depends on your definition of 91.205 (d)(2) What are people's opinions on dead reckoning as a means of navigation for IFR. Obviously its used briefly in procedure turns and holding procedures. But how about its use enroute to get you to a initial fix to pick up an airway. For example, say you have an airway running east to west 20 miles north of your departure airport. The only VOR to fly direct to, to pick up an airway is 20 miles south of your airport and you intend to take the east to west airway that lies 20 north of your departure airport on a route to the west. It seems dumb to have to fly 20nm out of the way to pick up the enroute structure. There lies a fix on the airway just northwest of your departure airport that would work nicely but for this example you have no GPS or Radar to get you direct to that fix. Could this be a situation where dead reckoning could be used to get you to the initial fix northwest of your departure airport lying on your intended airway? |
I'd refer you to 91.181, but I also know that ATC can let you do just about anything if you are "radar vector equipped". In other words, if they have you on radar and you stay above the minimum vectoring altitude, I can't see where there would be a problem.

If you have no means of determining your exact location, how do you know if you're about to hit a mountain?

OK...so how do you know if you're about to hit a Quaker Oats silo? I guess if you smell the crunchberries, you should probably climb. :)

LMAO...you get my vote for the post of the week on APC...kudos and crunchberries ROCK:D |
Its the best part of a CID overnight!

You could, but the question is should you? Personally I'd fly to the VOR, it's only an extra 20 miles.

Just hope that Count Chocula does not violate you for flying in a resricted airspace then then you will be downgraded to F/O Crunch. Ok I am really hung over and this was the best I can o. Where the hell did I put my pedialite and advill. |
