Use the ASA CX-3 to ace the FAA Private Written Exam
HTML-код
- Опубликовано: 28 фев 2020
- ASA CX-3, the electronic E6B flight computer, is a great tool that can legally be used during the FAA Private Pilot Written Exam. In this video, I will show you how to use the CX-3 to solve some of the questions such as pressure altitude and density altitude, wind components, wind correction angles, true course, calibrated airspeed, true airspeed, standard atmosphere, and cloud base.
More tutorials are available in our 35-hour Private Pilot ground school, available at pilotinstitute.com/course/par...
You can also enroll in our free 2-hour ultimate guide to become a pilot at pilotinstitute.com/course/ult...
For the complex questions near the end of the video I like to use the "Plan" menu and put the data into Leg 1. Enter the given values and it calculates your answer. No switching from "Wind Correction" to "Ground Speed".
This is an excellent tip! I am so glad I read your comment!
Huge time saver
Insanely helpful tip!
when using `PLAN` what would you use for TAS? and Var?
@@eliyahkaz TAS is going to be found in you POH or AFM according to your altitude and cruising RPM. It's not something that you come up with on your own. Var is the angle between true north and magnetic north. It's the red line that you see on your sectional. The closest red line is the one you'll use. Don't forget: east is least (minus) west is best (add)
Legitimately the most useful video I've seen for FAA Written test prep. You just made my life 1000x times easier
Saw this as an ad!👍👍🍹
100 true percent agree!!
Ouiiiiii me too im feeling so light then
This video is fantastic! If you just got the CX-3 this should be the first video you watch to not only familiarize yourself, but make life easier for test prep overall.
Time in route : when you do that calculation (PLAN, leg 1) then in the same window scroll down when done entering the data and you will find ETE answer.
So no need to take GS and go to another window to get time in route
I just bought the CX3 and found your videos. Wow! Great videos.
This video is the best. I passed my private pilot airplane knowledge test with flying colors. Greg thank you
Outstanding Henok! Glad I could be a part of your journey to becoming a pilot.
Sir this video is actually the MOST helpful aviation video I’ve ever seen. Thank you so much for doing it and making our life easier in how take advantage of our CX3. Cheers !!!
Wow, thank you so much Diego!! Glad we could help.
@@PilotInstituteAirplanes is that may use during the exam faa?
@@persatx3748 Yes it is allowed during the exam.
Thank you I suck at math and this will be a god send
My CX-3 hasn't come in yet, but just watching you solve these makes me EXCITED for it to arrive. I have been using my mechanical E6b and I'm excited to upgrade to a quicker way (especially since they took 30 minutes off of the Written).
It would be great if someone can post a video with Nav logs using the cx3😩
Excellent. I am SO glad I finally got my hands on the CX3. I love it.
This was an awesome video to use as source of learning for my PPL. Thank you and happy flying.
I just started ground school and I’m shopping for an E6B, this video was incredibly helpful and showed how simple it makes the calculations. Thank you!
This video demonstrated the CX-3 very well, demonstrating how to break the more complex equations into simpler operations.
I had just bought this calculator based on a recommendation from my flight instructor, and your video was awesome for helping me prep. Your tutorial was terrific and will help my efficiency on the test. Thank you!
Excelent tutorial, thanks.
Hey man, I have to tell you this video was awesome. I purchased the EX3 and the Sportys e6b because I wasn’t sure which was easiest to navigate and the video did it for me. It not only opened my eyes but it got my brain back into learning mode. It’s a no brainer as to which one I’m taking into my private pilot exam. Thank you for the clarity.
Great walkthrough and well done.
This took hours off of my study time!
Thanks!
Hey Greg, I am definitely getting one tomorrow (Tuesday) from Amazon
Great explanation! Thanks
Woah! This made my life easier!! Thank you so much!
Just got my CX-3; enjoyed the video. I'm about 50% thru on the PP course, so now I want to go back and check all my calculations in previous lessons with the new CX-3 and my notes.
I used the Plan function to get the 30 minutes answer for the last two of the last three questions. for ETA. Entered in all the data in the leg and then added the 2 minutes climb out to get the same answer.
I was struggling with the directions for my CX-3 now with your video ..it makes sense..Thank you so much for taking the time to show us how to utilize this.
You're very welcome, glad we could help make it easier!
Thank you for a GREAT tutorial!
THIS IS GOLD! Thank you SO MUCH!
Awesome video!!! Thank you!!
Fantastic video. I just bought this calculator. Can’t wait to give it a try.
ABSOLUTELY OUTSTANDING 💯
Great explanations, very helpful!
Iv just getting a CX-3 Flight computer and it take a bit to get the hang of it. but this video as help me alot I think iv got to practors a bit more to get the hang of it. but thank you for this video it was a great help for me
This helped tremendously. Thank you!
Thank you so much! Very helpful and very well explained!
fantastic explanation. THANK YOU
This is amazing explanation 👍👍👍👍 thank you very much 🙏
Amazing. This is exactly what I need!
Greg! Première bonne nouvelle de l'année. Je vien de commander en urgence ^^
Very useful video! Thanks
Excellent. Thank you
Thank you for this tutorial - very helpful! I will say that I found it easier to use the Xwind component chart than the E6-B. 🤣I'd love an example of cloud base where the FAA uses MSL.
Great video
Wow, I get it now. Thank you!
This video is great!! I love the question examples, pausing to calculate, and being able to have an explanation right away to check my work. Just got my CX-3 and I was lost. Great starting point not only in how to use the machine, but also how to incorporate it on the exam. Thank you so much! Hopefully you will be able to create more videos like this one.
Thank you, Thomas. We did publish an additional CX3 video here: ruclips.net/video/UbylIeItO2U/видео.html
Nice video content! Apologies for chiming in, I would appreciate your thoughts. Have you ever tried - Rozardner Flying Bird Reality (Sure I saw it on Google)? It is an awesome one of a kind guide for how to get pilot license without the normal expense. Ive heard some interesting things about it and my work buddy after many years got great success with it.
@Hashendra Hulangamuwa Yes, it is! :) I just bought one to use for my FAA knowledge exam.
"It can be used on all FAA and Canadian pilot, mechanic, and dispatcher knowledge exams." (www.asa2fly.com/CX-3-Flight-Computer-P1969.aspx).
I believe the FAA only specifies that you may not use a smartphone or tablet, but a CX-3 would be allowed.
FYI You can use Memory / Calc as such - saves few more steps and makes it even faster.
Eg. Tef ins from 30-50F @ 3000MSL -
Goto FLT> Altitude > Enter PAlt = 3000; OAT=30
DAlt = 1767
This is an awesome video thank you so much!
Best video my friend, thank you!
Nevermind I subscribed and just found it!
Thank you so much this cx3 was driving me mad 😡 lol 😂
Thank you so much!
Thanks!
great video! thank you
Nice Job...
Excellent thank you so much!!!
Great stuff!
Thank you for making this video! I wanted to see which E6B would be helpful on the test, and this was such a great tutorial and shows how the CX-3 works for these. On a side note, a lot of the steps can be skipped with simple math so hope everyone doesn't rely too much on punching in the numbers.
Outstanding! This lesson on the use of the CX-3 with great example problems could not have been better. I have watched it many times and worked through the problems - I could not have passed the FAA Knowledge Exam without it. I would really like to see a similar lesson for W&B using FAA KE example questions - as well as how to use the CX-3 W&B functions. Thank you very much!
Thank you for the kind words. We actually have not found the CX-3 to be very efficient for solving the W&B. It's a lot of steps and easy to mess it up.
You'll be happy to hear we just released this video for the W&B: ruclips.net/video/nxdhXKFzXrw/видео.html
Great tutorial. A Tip: you don't need to go into calculator mode. Simply press - and M and it will delete the memory number from the currently highlighted number.
Great tip, thanks for sharing!
I am student in your online school, thanks for this video (and all videos)... I purchased this calculator right after I saw the video in your school course, its useful device simplified the entire quizzes and tests ((BTW, I wish you move the video to the beginning of the course rather than the end similar to the other FAA written test tools video)) Thanks Greg for your great work
Passed the test with 88%....
This school and this calculator saved me time, money and increased my knowledge... Perfect.
You can do the more complex things in one step by putting them into PLAN as a leg.
Really helpful!
My opinion is it is better to master the pure manual device and become proficient in its use. The electronic devices are quick and very easy to use, but, the do rely on batteries, electronics which can fail. An E6B or, here in the UK a Crp1 calculator is quite easy to use. Just constant awareness of decimal places and it is a device that is guaranteed never to fail.
Thank you
Thank you for the mind blowing information i wanna become pilot 🤩🍷
Thank you 🙇 so much
Amazing!!
I think you have to convert C to F and then make that equate to that number as this does not work with Negative C values.
Underrated video!!
Thank Jbrooks! We just released it a few days ago so feel free to share it with more people!
Good Morning, Your video on the CX-3 is very good, at the end you ask if we have questions or would like to see more help, my request is can you please go over in detail the weight shift program on the CX-3, it seems a lot of questions are popping up on the CPL exam on this subject matter, so to get a better understanding of the function of the weight shift button would be of a great help to myself and I am sure others........Thank you
Here's a video that can help you: ruclips.net/video/nxdhXKFzXrw/видео.html
good stuff
Why aren't you just using the PLAN screen for the en route questions? It seems to do the same thing, but all one screen.
Does this calculator have a function for maneuvering airspeed?
Can you please explain as how to use Rat: __:1 variable in Glide function? Also as how to enter the ILS 2 dot(0.35°) deflection on a 3° slope to be entered?
Can you please cover weight and balance?
Greg, this is an awesome post! Appreciate you taking the time to run through the functions of the CX-3. Prepping for the AGI exam and the CX-3 calculations for PAlt are about 20-25 ft different than the results if using the mathematical calculations (and the correct answer) for standard pressure lapse rate.
Example: IAlt -1850 Baro - 30.18
CX-3 result: 1612 ft
Mathematical Result: 29.92 - 30.18 = -.26 (x1000 = -260); 1850 -260 = 1590 ft
Any ideas why the discrepancy?
The main reason is that 1000 is not the exact factor for a very precise calculation since pressure doesn't really exactly 1" every 1000 feet. The CX3 uses a more precise formula. For the questions on the exam, I would just use the figures they give you, best way to get the correct answer.
Can you please let us know how to calculate true altitude with cx-3. Thank you.
Im currently studying for my exam, although i dont have any questions i just wanted to say thank you for being so willing to help all of us students out here. I can see that more than half of the students don't respond when you do to their question. Don't let that deter you man cause its a huge help for us to learn from someone like yourself
Thank you for the kind words. We are going full forward helping as many students as possible.
@@PilotInstitute are you able to determine the compass heading with use of cx-3? i don't own an old school flight computer
@@Planeboy27 You can get from True course to Magnetic heading with the CX-3 and all you have to do is add the deviation (specific to each aircraft) to get to Compass Heading.
@@PilotInstitute Thank you! faster response than my damn instructor (instructor still hasn't responded, sadly)
@@Planeboy27 haha glad I could help!
Can you use the CX-3 to find magnetic heading?
You can use this on the exam?
Great video, quick question. When you were dealing with crosswind component I noticed you typed in360 instead of just 36. I also noticed that the answer was different depending on which one I would typed in. Isn't typing in 36 the same as typing in 360? And why would Answer. be different based on the input?
If you look VERY closely, you'll see that there is actually a video edit there. Yes, he did start to enter "360" for the runway, which is incorrect (it is a heading, not a runway). Very briefly, you can see it has runway "30" in the display (my E6-B won't take a third digit, so I can't put in 360). Then the video edit takes place (you can see his hand position "jump" slightly), the display now has the correct value, Runway "36". I completely missed that until your question.
Ive spent hours fiddling on my calculator In highschool when I didn't know what to do I think I got it covered
How do I do the second question with sporty electronic e6b? Is not giving me option to in put the pressure altitude. Please help 🙏!
Excellent video. Is it possible to get the takeoff distance on the CX-3? The (figure 40) takeoff distence graph is terrible.
No, unfortunately you have to learn to use those charts.
Thanks
The weight and balance feature wasnt covered, do you have another video on that? I know its simple, but i can't get it to calculate on its own
Check out this video we just published specifically for the W&B question. ruclips.net/video/nxdhXKFzXrw/видео.html
can someone explain why on the wind component questions you assumed that the runway was north (runway 36 or 360) is there a word im missing or is it just basic knowledge.
Hi Greg, Hope you and your family are doing well and staying safe during this terrible in our world. Can you use the CX-3 for the FAA 107 exam?
Thanks Fidel, we are staying at home like most out there. I hope you're doing well too. Yes you can use the CX-3 on the 107 exam!
@@PilotInstitute Glad to hear that. Love the program and thank you for the quick response
Determine the total distance required to land.
OAT 32 'F
Pressure Altitude 8,000ft
Weight 2,600lb
Headwind Component 20kts
Obstacle 50Ft
This is not a question that can be answered with the CX3. You will need to read the figure that is given to you and follow the lines. We explain how to do this in our Private Pilot ground school: www.pilotinstitute.com/course/part-61-private-pilot/
Awesome video! Thank you soooo much!!! Can we use this device at PPL written exam since has the memory option?
Yes it is allowed on the exam!
@@PilotInstitute I just got mine yesterday and start practicing watching your video and doing exact same question . Mine coming up totally different numbers. I have no idea why.
For example first question
IAlt 3894
Baro 30.35
PAlt 148266 yours 3500ft
OAT 25
DAlt 1380 yours 2043ft
What an I doing wrong ?
@@rasim81 That number is definitely not correct. Can you check to make sure all the units are correct (Inch of mercury and not millibars).
@@PilotInstitute I just checked and all the units are correct. I wonder if this is a defected unit.
Is there a way to use it to do the landing ground roll speed questions ?
Unfortunately no.
Thanks for the tutorial I’m terrible at math and the manual E6B. This makes things a lot more straight forward. Any chance you could do a CX3 with weights and balances.
Check out this video we just published specifically for the W&B question. ruclips.net/video/nxdhXKFzXrw/видео.html
Yes, So the way you have to put -10 Degrees C is convert -10 to 14 Degrees F. Then enter it in as 14 degrees F. It will then enter properly. They should make it so that you can just press the negative key and it shows next to the number such as -10 degrees C, it should take as -10 degrees C. and not change to 10 degrees C. Electronic computers sometimes makes mistakes and does strange things. Make sure you show all the steps and do not skip the steps. The problem is people fail to test the software and push it on us as beta testers. This is aviation. We need to get it right. THIS IS WHY THE E6B MECHANICAL COMPUTER IS STILL AROUND. There are way to many bugs with the electronic flight computers.
Hi, hoping you can help me with this one, using the cx3: Determine your fuel consumption for a 500 nautical mile flight using the following conditions? Pressure altitude - 6,000 ft, Temperature - +26°C, Manifold pressure - 21"" Hg, Wind - Calm.... The chart shows 11.5gph and true airspeed of 161kn
So you need to find out several things here: first step, find the ground speed, which in this case, because the wind is calm, is the same as TAS. So your next question is, based on Ground speed and 500 nm, how long will the flight be. Once you know that, and since you know fuel burn rate, you should find out how many gallons you will burn. Does that help?
Anyone know if these are allowed on the EASA exams?
Which electronic computer is better the ASA CX-3 or the electronic Sporty's E6B?
I haven't used the electronic E6B from sporty's so I'm not sure but the CX3 is definitely most popular.
Hi Gregg, can you please tell me how to enter NSEW in the coordinates plotting under rhumb line? If i want to enter 50deg how do i tell the cx3 if its north or south under latitude? Or if i want to plot 30deg longitude, how do i tell the cx3 its east or west? Thanks
Try to use the - sign for West or South coordinates. I have not had much chance with the thumb line calculations.
Just bought the CX-3 flight computer. Preparing to take my private pilot exam. Can’t find the percentage key on the calculator. Does it have one? As you may be aware some of the exam questions require a percentage answer.
You can use the simple calculator for that. There's no percentage button per se but if you need to add 20% for example, simply multiply by 1.2. If you need to remove 20%, simply multiply by 0.8.
Ok, thanks.
How do you put in a negative C. This Calculator does not do negative Temp in C. It will state the negative sign but then when you press the = key it goes back to positive. What kind of Training is this.
Can u tell me the steps to follow for calculating W/V and drift Angle...
I have unfortunately not used this function yet because it's not really needed for the exam. Do you have an example of a question you're trying to solve?
On the Airspeed, my CX-3 came out with 140.78 CAS?
In case you're wondering a year later...I had the same issue. I found out I was calculating with temp in F instead of C. Once I changed units to Celsius I got 137.16!
Where can I confirm on FAA web site that CX-3 or electronic E6B is allowed in Private Pilot written exam? I heard examiner has right to take it away and ask student to use manual E6B. is that correct?
I don't remember where it is specifically but the CX-3 documentation explains it is allowed. The "examiner" you are talking about is the DPE at the end of the course during your checkride, they can tell you that any of your electronic devices are broken, how do you work the problem now. As far as the written exam, they are not allowed to do that.
