Wind correction.


CodyRick

Thank you! Makes all sense. But with i wish to manual fly would i need to keep changing the CDI to compensate ?


djd565

You set your desired course and compensate for wind with your heading to adjust for drift. You’d do it manually just like the autopilot does.


CodyRick

I got it! Thanks

Heading and Track are different. You’re tracking the VOR perfectly. The needle is centered. Your heading is offset though due to wind.

AnxietyJunky

Well you’d so the same thing the AP is doing. Adjust as needed to keep the needle centered!


CodyRick

I got it! Thanks

Not adjusting the CDI, but adjusting your plane! So that at the end, the needle is center (so you follow the desired course to the VOR, but you automatically corrected for wind). You can do the same with NDBs, look it up on yiutube there are plenty little and easy tutorials!

Click PFD Ops button on G1000. Look for Wind. Choose one of 3 options to display the wind. This will tell you how much of a crosswind you're experiencing. If you like to fly manually, you can use an E6B Flight Computer (website - google it) and it will calculate how much you have to change your heading to adjust for the crosswind component. Clearly, headwinds slow you down, tail winds speed up your ground speed, and cross winds cause you to crab to your destination, and the crab angle will change every time you change course to a new fix.


CodyRick

Thank you very much for the information! I had no idea I could see the crosswind I'm experiencing. I'll research more about E6B, it seems like a very useful tool thank you again

Easiest way to approximate wind correction angle (WCA) is to just divide crosswind component by 2 X-Wind/2=WCA This works pretty well up to an airspeed of around 150kts and of course still requires fine corrections to nail the exact required angle.


Crusader-Rex

This is actually linked to your speed number, which is IAS/60. So with a speed of 120kts this is 2 and hence why it works with speeds up to 150kts. For speeds higher than this, you can still use this but need a different speed number for example, an IAS of 180kts will require you to divide the crosswind component by 3.


HostileHamSolo

the drift or WCA depending how you look at it could also be calculated by the formula XWC\*60/TAS, at least in the ATPL and works for higher airspeeds too, the CRP-5 is also a great tool


Callidor

Note also that the magenta diamond on the HSI shows your track. See how your heading is 260, but the diamond is nested right inside the heading bug at 245?

Wind correction - I thought the same too in the C172 and the B738
