Quickly calculating the crosswind component in real world flying is important for crosswind take off and crosswind landings. In this video I am going to teach you the mental math I use to make these calculations quickly in my head. Its not realistic to always have your phone or an E6B out so this will get you close.

@timturner8754 4 года назад

Thanks for the interesting and informative videos. Cute linear estimate of sine function. It fails at low and large angles. You mentioned the high angle correction: if 80 degrees or greater (sin ~ 1) just use the full wind speed. The low angle correction is also easy. If the difference angle a is less than 20 degree, divide angle by 10 then MULTIPLY by 2 (that is, 2(a/10)). This is just a little different than your middle angle estimate: divide angle by 10 then ADD 2 (that is, a/10 + 2).

@patrickpoeschl2966 4 года назад

Good tip. I use a lot more WAG (Wild A$$ Guess) in my mental math while I'm hand flying, though.. In my case, if the wind is not directly down the runway or a direct crosswind, I round it to 30, 45, or 70 off runway heading. For 30, the crosswind is 1/2 the velocity. For 45, it is 2/3 the velocity. For 70, it is 90% of the velocity. That gets me close enough. Of course if I suspect it will be near a limit, I pull out a chart to make sure I'm legal. My WAG gave me 9 kts crosswind for your example.

I've loved aviation ever since I was a teenyweeny little one. I wanted to be a pilot when I was in high school (well, wanted to be a pilot in the USAF actually) but Dad said no to enlistment, as I was too young to do it myself at the time. Got into the airline industry at the local int'l airport, then, after a few years, went inflight. I'm now in the finance industry, (inflight OJI) Miss my flying days and still dream of being a pilot but this whole MATHS thing is scary!! And I LOVE learning!! :) You did make it less intimidating though. Even though this is one of your HELLA OLD videos, it helped minimize the fear. Thanks for sharing your tips @74Gear !!

This is a good method. I use an old sniper trick I got from an old book on shooting. sin 10 = 1/6, sin 20 = 1/3, sin 30 = 1/2, sin 40 = 2/3, sin 50 = 3/4, sin 60 = 7/8, sin 70 = 15/16, sin 80 = 1, sin 90 = 1. You have to commit to memorizing the number but once you do that you just go straight to the answer.

Another way to visualize the crosswind component; The wind calculator on the back of an E6B very closely resembles a DG or HSI. Once you understand how to use the E6B wind calculator, visualize the E6B wind calculator over your DG or HSI to guesstimate the value of the crosswind component based on your current heading and wind direction..

@papalazarou6874 2 года назад

@@johnhorvath9878 Heading is 090 - drop the zero call it 9. wind is 060, drop the zero call it 6. 9 (hdg) - 6 (wind dir) = 3. Add 2. ALWAYS add the 2 no matter what, to the difference between those numbers. Just accept you add 2 at this point of the calculation. It could be 25 - 18 ( = 7 + 2 ) or 12 - 4 ( = 8 + 2) any numbers - you just add 2. So, now back to our friends 74Gear example in his video you have 5. Now the wind strength is 18 knots.. make it simple, call it 20 knots, and now again drop the zero (so 2) Take your 5 (which we got from the first (hdg - wind) + the 2 (that ALWAYS gets added there) (so we get 9 - 3 + 2 = 5 at this point) and multiply by the wind speed (which you've over corrected for slightly in our case it is 2) so 5 x 2 =10. Because you slightly overcorrected on the windspeed (by rounding 18 kts to 20 kts (we dropped the zeros remember) to make the numbers simple rather than having to multiply by 1.8 we multiplied by 2 - we take a knot off. If the speeds were higher we might take off 2. So we get around 9kts. It's not exact but good enough for a quick calculation. It's a rule of thumb - like getting Celsius/Centigrade to Fahrenheit has a formula based on (°C × 9/5) + 32 = °F. Who has the mental maths for that everyday? Double Celsius and add 30. Fahrenheit to Celsius? Then - 30 and halve. Is it scientifically perfect? No, but it's close enough for quick numbers. Hope this helps you or anyone else - more than the other reply you received, which was "no". I don't understand people sometimes. If you can't offer a constructive or helpful reply, don't reply at all.

Hey 74Gear do you know how to calculate the SEL/OAT Temp?

@ondownwind Год назад

Crosswind formula is Crosswind = wind speed x (sine). For me, the clock method works best. Picture a clock: 15 minutes = 25%, 30 minutes = 50%, 45 minutes = 75%, 60 minutes = 100%. In the test question, the difference between runway 9 and the wind direction is 30 degrees (30 minutes on the clock). 30 is half (50%) of 60; half of 18 knots is 9 knots. This method is more accurate as the (sine) of 30 is .5 or 50%. Take the previous example again: Runway 9 with 50 degrees. 50 minutes is 80% of 60. 80% of 10 is 8 knots.

Did Atlas teach you to calculate your Xwind like this in the SOP lol! I am an airline pilot and Ik for a fact people never calculate the crosswind component like that in there head. Most of the time the FMS or MCDU will tell you the crosswind component or your EFB has an app where you punch in the wind direction, runway and wind velocity and it spits out your crosswind component. A lot of the time more important things to do than you trying to calculate all this in your head.
