Hey guys, I just had a few questions about the e6b, and I was hoping any of you could answer them. I'm just about ready to to my solo x-country(ppl) but the only thing holding me back is filling out my nav log correctly. I have everything down exect how to find three things. 1.) TAS 2). TOC/TOD/ 3). GPH fuel used. I know that for my toc/tod I refer to my poh but I'm still not getting it. I have already done 3 ground lessons with my instructor. Alot of money just to figure out how to use the freakin e6b. The electric e6b I'm sure is easier to use but my instructor wants me to know how to use the e6b first. Anyways my instructor said he was going to put a reference guide togather on how to use the e6b but in the mean time, if any of you can help me out , then even better. Thanks!!!:confused:

The electronic E6B is much easier to use and can be used on checkrides and written tests but you should learn the manual one as well. As far as the three things you need to find they are all in the POH with the exception of the TOD. In the 172 POH turn to the performance section for the TAS in cruise at different altitudes and temperatures. Before the cruise performance there is a page for the time, fuel, and distance to climb and thats how you can determine your TOC. For TOD you can figure the difference between cruise altitude and traffic pattern altitude then multiply that by 3. So if you're cruising at 5500 and TPA is 1500 you need to lose 4000 ft 4x3=12 so start a descent 12 miles out. If you have gps multiply your groundspeed x5 and use that as your rate of descent. So lets say your doing 120 over the ground u descend at 600 fpm(120x5=600) at 12 miles out that should put you at TPA over the airport.

Get the Jeppesen Private Pilot Test Guide. It has figures and problems you can work through and it walks you through the steps. Its tough at first but youll catch on.
 
You're going have to whip that thing out and just practice using it to get really proficient with it. I still use mine to figure stuff out.

You don't need the E6b for any of that, maybe that is where your trouble is. Look in the Performance section of the POH. In the Cessna POH, it is section 5. You are looking for the climb and cruise charts.

The climb chart will tell you (estimated) TAS in a climb, Time, Speed, and Distance it will take to reach a certain altitude, and the fuel burn.

Use the cruise performance chart to get your cruise TAS, and fuel burn.
 
Ok so coo, allthis feedback is helping out. In my POH for the cessna 152 , on the cruse performance chart it shows 2000 / 4000 /6000/ 8000/ ect.... so if I'm crusing at 4,500 would I just split it between 4000/6000/ ?
 
You'd interpolate. . . so, perhaps not half, just a quarter.

Also, just write up your own practice questions for the E6B, that's how I learned.

Made up 5 or 6 with time, distance, and speed problems. 5 or 6 fuel burn, at what speed, and at what distance type as well. You'll soon learn how easy it is to really use - heck of a lot you can do with that silly thing.
 
Also, as an alternative to the bulky E6B, you may want to consider purchasing a Jeppesen CR-5. Much better flight computer IMO. It does everything the E6B does. It's also light, small, and fits in your pocket! :)

Alright guys I'm going to give it my best. Thanks for all the help and I'll keep everyone posted.

This is how it should go:

Figure out your TAS and TOC and all of that jazz with the performance charts, and use that info for your initial climb out.

Use the E6B to get your Wind Correction Angle, and your GS for those lines.

For the rest of it, you use the Cruise chart to get your TAS, figure your GS with the E6B, and figure out the time from checkpoint to checkpoint (you should already have measured the distance with your plotter) with the E6B, and from there, how much fuel you will burn for that leg.

Also, on the climb chart, it will say to add X amount of fuel for taxi, runup, etc...For the 172, it is 1.1, so it should be around .7 - 1.0 for a 152.

Remember that those altitudes are pressure altitude....not true altitudes.
