- This is the easiest way to calculate cross-winds! You don’t have to pull out your cross wind chart to calculate crosswinds before you land or take off any more this is a much simpler method to calculate the crosswind component. The clock method of crosswind calculation has been used for years by many pilots to get an estimate of their crosswind component. You should use it too!

I've used this method on my landing briefing. My examiner loved it lol
Awesome! Did he ask you where you learned it?
Absolutely brilliant.
Thanks!
There’s another method, probably less accurate but quick and easy.
Crosswind
0 to 30° = 1/3 of the wind speed (Vw)
30 to 60° = 2/3
60 to 90° = 3/3
Headwind
0 to 30° = 3/3
30 to 60° = 2/3
60 to 90° = 1/3
😊✌🏻
Love it! Thanks for the comment!
I also use this method for mechanics as a backup for Atis local airport frequency when performing jet engine runs
That’s super cool
Amazing and Easy! You're the best. Thanks for sharing this.
You’re welcome
I just eyeball it and land.
😆
Same
Excellent tip.thank you.
You’re welcome!
Yes
considering the following:
sin(30°)= 0.50
sin(45°)= 0.70
sin(60°)= 0.87
I used to apply these:
diff:30° -> Xwind= 50%, Headwind= 90%
diff:45° -> Xwind= 70%, Headwind= 70%
diff:60° -> Xwind= 90%, Headwind= 50%
Thanks for this!
Very useful
Thanks a lot!
That's awesome!
HI josh !
in 0:54 i think you have to say 15 . 0.25 instead of 10 , because we have 15 degrees
I’m a little confused about your question. 15 degrees is our 1/4 mark or .25. 1/4 of 10 knots is 2.5 knots.
absolutely love this
Thanks!
Thanks!
You’re welcome!
Do I have tje Time to calculate all this in my head while approaching or there some devices get this done quickly???
Yes. If you practice, you can do this in seconds in your head
Now this thing goes totally diagonal from my head
Could also guide how to calculate which runway to pick according to wind direction. Spl if wind is from 350.
Would also like to take this opportunity to Thkyou for the video as a beginner it has made things and aviation life easy for me.
You’re welcome!
Very cool.
Thanks!
Where did you get 350 from
Runway 35. Meaning the runway is pointed at 350°. General rule is to always add a 0 at the end of runway numbers to get the heading it’s facing.
Can you run some examples where the difference between the wind and the runway heading doesn’t land you on a convenient 1/4, 1/2, 3/4, 0 part of your clock?
If you pick the closest one, you’ll still be within a knot or two of the chart. I show more examples at the end of this video right here: th-cam.com/video/RMitIgzeSgo/w-d-xo.htmlsi=-cJWiuk8EnXLf-bg
What about dividing the windspeed by 6 and multiplying by every unit of 10 degrees off from the runway? Example RY36, wind 04012kt. 12 divided by 6 is 2. The wind is 40 degrees off RY36, so 4. 2 x 4 = 8kt crosswind roughly.
I haven’t heard that one
Student pilot here (26hrs into my PPL). How bad is it if I just "feel" the wind. My best landings in crosswind have always been when I just turn my brain off so to speak, point the nose in a way so my course aligns with the runway, and just fly her in by the seat of my pants and keeping an eye on airspeed. The more I try to think about getting some exact heading based off the math the worse my landings, I think it distracts me from just flying the plane. I'm decent at math but my brain for whatever reason just freezes up over even basic calculations when I'm flying if there's a lot going on. Is a DP gonna expect me to announce my crosswind component or something? Is flying by "feel" bad?
I don’t have a problem with it in most cases, but there are actually some airplanes with a crosswind limit, so you need to be able to calculate this
@@FreePilotTraining thank you!!
@ OP:
Hi there. Tell me, do you teach your students to look at moving cloud shadows on the ground to calculate wind direction and drift on cross country flying?
You’re making excellent progress on your channel. ❤👍
I don’t. The wind where the clouds are is usually not the same as the wind on the surface or even your cruising altitude. If it was, that might work
@@FreePilotTraining
Oh I see I have confused you. I am of course referring to clouds at the same or slightly higher altitudes while maintaining VMC. Naturally at different altitudes this would be impractical. This was passed on to me by a former Royal Air Force Hurricane pilot who flew in the North African campaign during WW2.
Edit: I should point out that most of my aviation experience involved dead-reckoning navigation in Africa without the benefit of GPS, NDB and VOR, LORAN Etc. So when a pilot/navigator from WW2 in the desert campaign offered me advice I took it.
Perhaps this tip is not so useful these days.
Hello! Not sure if you are aware, but a TikTok user is posting your content (on their account) which is in clear violation of their IP guidelines. I found 7 of my channel's videos on his account. If you would like more details I am happy to share. I just wanted to let you know as a fellow creator.
Thanks for the heads up! I’ll take a look
Neat method but considering my history with math, I probably should not use this while trying to land. The plane might be missing a wheel or two otherwise lol
Lol. I’m bad at math too
What about a quartering tailwind?
Above 90 degrees, you can use the crosswind component the same way. Your crosswind component would be calculated based on your “angle off” from the direction you are traveling. For example, if I’m landing runway 18, and I have a quartering tailwind at 015 at 10 knots, I would take 1/4 times 10 to get my crosswind component of 2.5. There is no headwind component in this case, and my tailwind component is now 7.5
I dont get the last part i watch it 4times wdyk my crosswind component pardon
Thanks for the comment! I go into a lot more detail on the video below. The crosswind stuff is towards the end of the video.
th-cam.com/video/RMitIgzeSgo/w-d-xo.html
or you can just calculate the sine of the angle in your head.. haha..
Yeah this is useful
actually.. I calculated the sines.. and 15 would be 2.5, 30 would be 5, but 45 would be 7 not 7.5.
😂 I can’t even remember how to do that with a calculator
My method isn’t perfect, but it’s close enough for determining crosswinds
@@FreePilotTraining yeah, I certainly don't want to have to pull out a calculator
Usually excellent content, but this one is a swing and a mess. How would I use this to apply appropriate aleiron and rudder control on final? If I'm worried about calculating the maximum crosswind component for my aircraft on a small angle, should I be flying anyway?
I appreciate the feedback. Sometimes the wind picks up after you take off.
@@FreePilotTraining thank you for reading and responding. Not trying to be disrespectful, but as conditions change noted during atis reports and even the few seconds on final, the pilot will respond instantly as appropriately vs determining actual crosswind component.
When you become an even better pilot, you'll never need to compute the crosswind component ever again. there are easier methods. Heck, I can land without knowing the actual wind direction or speed at all. I use a trick that is never taught, and that most pilots probably don't even know (based upon the fact no pilot I've ever shared it with knew my trick before I shared it).
Lol. These days I’m mostly concerned about a tailwind. It can lengthen that landing distance a lot!
@@FreePilotTraining but sometimes you have to land with a tailwind. I spent most of my time in training flying in the Rockies, and we had some airports you just had to accept the tailwind. it's perfectly safe if you know what you're doing and how it affects the landing. We'd even takeoff with tailwind. Sedona was a great example, but we banned students or renters from going there without a CFI as too many accidents happened.
High DA, sloping runway, cliffs, rising/restrictive terrain to the north.... Even if the wind was out of the north, we always took off south. down sloping runway, flat descending terrain, away from town, could descend to pick up speed if you got in trouble, lots of flat open areas to land...
And the winds from the canyon, cliffs, and other terrain could make it tricky too.
But I like a challenge. at this point I actually don't fly sometimes if the winds are too calm, as I hate landing without a crosswind. it's too easy and no fun. But in some ways Xwinds are actually easier too.
Please share this method then.
Very cool hack.
What if the wind speed had been not 15° but 20 or 25, 35...?
@@arturogutierritos4538 "What if the wind speed had been not 15° but 20 or 25, 35...?"
what does this mean? I think you're mixing your units/variables?
Degrees are units of angle, not speed. So are you asking about speeds of 15, 20, 25, 35 KNOTS, or are you asking about some wind speed at 15, 20, 25, 35 DEGREES?
Hey I've got another explanation.
Let the wind vector be at 335 degrees with value of 10knots
Difference between the runway and wind vector is 15 degrees
So for vector components it's always one vector which is the |v|.cos (theta) and the other one is |v|.sin(theta). The sin theta component is always and always along the angle and the cosine component is always on the other side.
So for this condition we require the sine component sooo the answer becomes
10.sin(15) which is approximately 2.59 or 2.5.
Pls tell if it was nice. We actually learn all this in grade 11th in basic physics and in grade 12th in mathematics.
I know I’m gonna get a lot of flack for this comment, but if it is like you say my hands are full meaning I’ve got a lot going on and the wins from ATIS are already showing me a bad scenario. I think the permanent thing here to do next is very simple.
Go around and divert. Find an airport where the winds are directly or close to the centerline and wait out the windstorm or whatever is going on
Pushing your luck, especially scenarios where you are not ready for that type of crosswind is only going to increase your chances of a bad outcome ..
I say this to everybody so please don’t get offended. I love this channel but thousands upon thousands of people listen to your every word. I’m sure you know this and being the proficient Cfi, MEII or whatever ratings you hold you have a responsibility to be very careful with your words. I feel like TH-cam is a great tool, but it doesn’t make you a pilot or give you the experience of having the stall Warner go off at 200 feet AGL and crapping your pants, true story.
By the way, my CFI gave me a good whack when that happened. There were no words needed. Just a good slap to wake me up out of a stupid silly situation that I caused by letting my airspeed decay. I never did it again and I don’t think that TH-cam video will replace that.
Thank you for your contributions very good. CFI and this channel is amazing. .
Love peace and respect from KLZU.
I’m a long time student pilot only about 250 hours I work for a flight school and an I’m an A&P full disclosure.
PS : I wasn’t trying to be disrespectful or contradict your information. Your channel always gives great information and I am happy to be a subscriber. Thank you for taking time to make all these informational videos. You do a great job. Thank you again. From 1 CFI to 1 student. lol. STAY SAFE BROTHER.
Great thoughts, but there are also going to be times when you CANT divert. I’ve seen this first hand in Alaska. Love your decision making process though and I appreciate the feedback
as a kid that hasn’t started training at all: w h a t
Too fast, not helpful.
What difference at this point does it matter You have to land. I've put a Cherokee 6 down on runway 4 (SANDED) after an ice storm with winds 300 at 25 G 35. Low in gas and alternate 00 in BS (Blowing Snow). U either have the skill or U don't belong there.
Lol. Very true. It’s just a tip
@@FreePilotTraining Roger Tower ya gota know your Personal Limitations ... When i left the runway it was pure ICE on the taxiways with 6' Snow banks and the 6 was trying to go sideways. 300 HP helped it SKATE to a tie down.
hound.. that's bad planning rly and bad adm .. not safe at all
Goodluck
