One quick note about this lesson that I forgot to mention is that lines of longitude converge at the top and bottom of the globe. This means that as you go farther north or south away from the equator, one minute of longitude is slightly less than a nautical mile and it continues to get smaller as it gets closer to the top and bottom of the globe. You shouldn’t get asked this on your written exam, but you should be aware of it.

[@9LimaAlpha7]

mmm, what is the reason for this occurrence??

[@studiocuisine238]

I REALL APPRECIATE YOUR PROMPT RESPONCE but what i don't understand is why the 3 digits in the seconds

[@FreePilotTraining]

@@studiocuisine238 Ah, yes. This is a huge problem if you’re looking for precision. If you don’t need precision, what you’ll typically find is coordinates in Degrees.Minutes.Seconds. But if you need really precise coordinates, what you need is Degrees.Minutes.Minutes. If you see 3 digits like you describe, these are MINUTES in decimal form and NOT seconds. It’s a little more precise with this format. That’s why the Army uses MGRS. you don’t have the danger of confusing the two

[@livestock9722]

So there's really only a portion of the Earth where measuring this (miles) way east/west is relatively accurate.

[@richardweldon2062]

This is the best explanation of longitude/latitude I've come across.

[@FreePilotTraining]

Thanks! I love hearing that!

[@niqueybangz]

Thanks for this! Studying to pass the written on my own because flight school is so expensive so I’m doing as much as I can before I take off 🙏🏾✈️💙

[@FreePilotTraining]

You’re welcome! So glad I could help!

[@Jeffrey-Flys]

This… is the most well paced and complete explanation of the 7 ground schools I have used. Thanks Josh! BTW …. I am already passed the written stuff, just constantly reviewing your stuff…

[@FreePilotTraining]

I really appreciate that! It means a lot!

[@davegrundgeiger9063]

Super clear lesson!

[@FreePilotTraining]

Thanks Dave!

[@ashleyw.3069]

No one... I mean no one... explains this concept better than you. I totally understand how to read these charts now. Thanks again!

[@FreePilotTraining]

Thank you so much! That means a lot!

[@noahprince247]

this was a great refresher for me, short enough to be engaging, no extra babble, and great visuals to connect the dots (no pun intended) for us visual learners! A+ subscribed.

[@FreePilotTraining]

Thanks Noah! I appreciate that. It keeps me motivated!

[@veritsult8034]

[@grantbunker1755]

Love your channel and will continue to watch. More please! I'm at a stage check and feel way behind of where I should be

[@FreePilotTraining]

Thanks! I’m uploading them as quickly as I can without sacrificing quality. I’m working on one right now which is all about improving radio comms per requests from several people. I know everyone struggles with that. I’m hoping it will help. Don’t worry. Everyone feels behind. At some point, everything will just click.

[@scriptoris1947]

The way you explained it helped me figure this out. Thanks a ton !

You’re welcome! Thanks for watching!

[@chuckcampbell3927]

🛫📖🛬 I cannot compliment you enough for the work and the labor that you put in to this training course. It certainly isn't free, Not when you consider all that you have to do to put these uploads there for people like myself who want to get a refresher in the comfort of our own home, It cost you plenty and I know you sacrifice to do it. So please accept my thanks and BTW; GOD has given you the gift of teaching, But most importantly he has given you the heart to share your knowledge. ("Freely have you been given Freely give again") Cordially/Best wishes 📖🛐✈️

Me ->searching the comment section for flat earthers 🤔. This is the best video I’ve seen on this particular topic.

[@FreePilotTraining]

😆 I was hoping for more comments from them. Thanks!

[@phoonjzc]

Where to get FAA exam questions?

[@simonsays1990]

It is best not to consider longitude as being a measure of anything but time relative to greenwich, on nautical charts only the latitude scale is used for measuring.

[@FreePilotTraining]

You are correct. I plan on fixing this part of the video when I can. I believe it builds a basic understanding of latitude and longitude for now though until I can get it fixed

[@studiocuisine238]

THanks a lot for this video can you please tell me how would you count thid 36°43.082 N 3°10.613 E I would really appreciate prompt answer man Thans

[@FreePilotTraining]

Let’s do North: 36x60 NM= 2,160+ 43nm = 2203NM .082 would be .082 of 1 NM so (.082 x 6076) 498.232 feet you are 2,203 NM and 498.232 feet north of the equator. The Eastern longitude is technically not accurate because lines of longitude converge (get closer together) as you get closer to the poles

[@microsnook3]

So, if we watch your entire video series, will we be prepared for the written test? Also, can you explain to me the order of operations, please. Groundschool is the means of understanding for the written test? The oral test comes along with the checkride? Or is it separate? Then flying is learning the aircraft, and the final "exam" is the checkride? I just started and am a little confused about the order of operations. I only have a single flying lesson under my belt and my instructor is having me study on my own and mentioned to take the written soon to get it out of the way. Thank you very much! Just need a timeline for better clarity if my question makes sense. Really appreciate your videos. I will be watching them all and then probably watch them all a second time. Cheers

[@FreePilotTraining]

Yes! This series will prepare you for the written test, but you must get an endorsement before taking the written exam from an authorized instructor. I don’t have the ability to give that out…yet. As far as the oral goes, that’s part of the check ride. You might Mike this video: kzbin.info/www/bejne/iICpmpyhn8ifbbMsi=ucF3Cjs205L0rpwU

[@microsnook3]

@@FreePilotTraining I'll check it out, thank you very much. I have an instructor, so I am assuming he can write my endorsement for the written.

finally now i understand feel like thanos

[@victor-emmanuel7485]

thanks for the lesson! If I may give you some advice; the animated hand is rather distracting for me.

[@FreePilotTraining]

You’re welcome! Yeah, I try not to use the hand as much in my newer videos

[@Skiddadlin_]

How did you get 29 minutes for the west coordinate? I can understand the north one being 17 counting laterally, but I got lost when you got 29 minutes for west

[@FreePilotTraining]

Great question! Remember, the unmarked latitudes and longitudes are only 30 minutes of latitude. In other words, they are only 1/2 of a degree. That airport is 1nm (or 1 minute short) of the 30 minute line, so it’s 29 minutes. Hope this helps

[@Skiddadlin_]

@@FreePilotTraining ohh gotcha I understand, thanks!

[@FryChicken]

1 degree = 1 nautical mile must only be true at the equator for the longitudes.

[@FreePilotTraining]

Yes, that’s true. This video doesn’t talk about convergence. At some point, I’ll remake this video

[@ramoramo962]

Sorry in advance for a probably stupid question (also sorry for any grammatical errors, I am not an english native speakter). At 5:48 you said: "we know that we are in the western hemisphere BECAUSE these numbers count up as we travel west". I don't get it. Wouldn't the numbers still count up if you are going to the east from the 0 degrees mark (only differing in the letter E instead of W)? In your case it is obvious for me that we are in the western hemisphere, but for another reason (the reason being, that I know you are talking about places in the US). Could you explain how I recognize that a place is in the eastern hemisphere with just having the number of degrees and without having the letter "E" for guidance? I hope you know what I mean by that.

[@FreePilotTraining]

West of the prime meridian, lines of longitude count up as you move west. East of the prime Meridian, they count down as you move west, and count up as they go east. Hopefully that helps

[@shch1829]

@@FreePilotTraining I have stupid question too. What you said it is obvious that this is North. Just common sense? Or how to read from the map?

[@omarfaris8273]

omg better than my teacher

[@FreePilotTraining]

Thanks!

[@unshapingtheearth7916]

Why dont they say 32 hours north of equator instead of degrees🫥

[@FreePilotTraining]

Great question. Degrees are also divided into minutes and seconds

[@phoonjzc]

latitude are horizontal while longitude are vertical.

[@phoonjzc]

60 min in between every degree of latitude and longitude every min = 1 nautical mile

[@phoonjzc]

I confused between time and distance. Why they related? Can anyone explain?

[@ahmetoguz5291]

there is a miss calculation here. The distance between two longitude is not the same as you go north or south. So At the equator the distance between two longitutde is 60 nm but in your example your at north so the distance between two longitutde cant be 60 nm.

[@FreePilotTraining]

That is true. This video doesn’t account for the longitude getting closer at the poles, but the principal is still there. I need to redo this vid
