How to use Sporty's E6B Flight Computer - sample problems (heading/groundspeed, crosswind/headwind)

[@AirJoe]

I have one of these but never used it before. Ive kept getting these questions while studying amd now ill be able to answer them Thank you!

[@mytech6779]

I just bought one of these (spring 2023), Not sure if this is a "feature" or a defect but the display is nearly unreadable straight on, it only clears up at more than a 45degree angle and that much skew causes readability issues of its own both for the dispay and button markings in addition to making hand held use awkward. I understand having some veiwing angle bias for use on a desk, but 20degress would be the practical upper limit.

[@camjcasey]

sounds like there's an issue with your screen. I'd send it back. Shouldn't be doing that.

[@Sienna_bee]

Def not normal, I bought one June 2023 and it is very clear head on. Get an exchange

[@AirJoe]

Mine does that too.

[@Pilotjosiahnaraidu_20]

Thank You very much I really understand how to use the calculator now! #THANK YOU JESUS!!!

Test question has an input of -10°C. How do I input a negative number? Edit: I figured it out. Just type in the number and then push the minus key. I thought it was part of the “conv” system. Hope this comment helps someone else.

Under the Pressure & Density Altitude function, I am getting different results using the formula than the E6B function in the example in this video. PALT= (29.92-29.83)*1000 + 843 = 933. The example has PALT=926. So, what am I doing wrong?

[@rong4248]

I don't think you are doing anything wrong. The E6B takes the humidity into the calculation. That will change the PALT and DALT. At least that's what I think the reason is.

@@rong4248 thank you!

[@FluffyFluffles]

@@rong4248 It has nothing to do with the humidity, you can tell by the fact that the e6b takes no input for humidity/dew point or anything that would tell it the current humidity. The difference is due to the *1000 calculation being a rough estimate that we use because it's easy to calculate and remember. The E6B likely uses the official, more accurate formula: station altitude + 145366.45*(1-(station pressure * 33.8639/1013.25)^0.190284)

I'm doing test questions from gleim 2024. question 55 on p234. after putting all numbers the calculator is off by approx 4000. redid it 3 times and always same result... total mom should be 80.8 but calculator gives me 76.2. so how can I use it for a ffa ppl test???

[@joydasgupta9445]

Airlines now give iPads for calculations so is it still needed?

[@DaMojoIsDead]

This would be helpful in FAA written exams since they're allowed in testing centers. Other than that, it's just another tool to use at your disposal.

[@TheDuckofDoom.]

Where is the back button? Like if I am doing WT/MOM and accidentally start entering a number in the CG field, how do I cancel that input without completely restarting the entire aircraft W&B from scratch? I'm not sure why that is so easy to start with, CG should only be an output in wt/mom mode, but the simplest bumped button can over write it and destroy a rather long string of inputs. Really not user friendly, and with the recent reduction in test time and slight increase in question count such a mistake can be very costly. So I hope I'm just overlooking something.

Is there any reason my sporty e6b is showing the wind correction angle like this one? I just bought it a couple months ago.

[@TheDoodoo42]

Thank you.

[@douga8606]

So sorry, have not used an E6B since the last century. I don't use a slide rule or adding machine either. All those features are done automatically by Foreflight and other computer programs and apps.

[@sportyspilotshop]

Yes they are, but unfortunately you can't take ForeFlight into your FAA written test. So the E6B lives on.

[@TheDuckofDoom.]

My tablet had an issue and needed to be rebooted in the middle of my last oral exam. I was able to immediately continue with manual calculations and several exam questions before the tablet and foreflight were back in action (including re-entering flight info). It wouldn't have been a good look to just sit there and wait "but I need muh foreflight to tell me"

lol yy

[@aviatormv]

Mobile apps 🤷‍♂️

[@dimitrijensk2845]

Can’t use that on the test

[@aviatormv]

@@dimitrijensk2845 when i did my ATPL exam i was not allowed to used an E6b calculator either and was also restricted from a wrist watch. No joke.
