This article has been rated as Start-class on Wikipedia's content assessment scale.

This article has not yet been checked against the criteria for B-class status:
Referencing and citation: not checked Coverage and accuracy: not checked Structure: not checked Grammar and style: not checked Supporting materials: not checked	To fill out this checklist, please add the following code to the template call: \| b1<!--Referencing and citation--> = <yes/no> \| b2<!--Coverage and accuracy --> = <yes/no> \| b3<!--Structure --> = <yes/no> \| b4<!--Grammar and style --> = <yes/no> \| b5<!--Supporting materials --> = <yes/no> assessing the article against each criterion.

This article uses the terminology "standard rate turn" - is this a "Rate 1 turn" in UK parlance - i.e. 180 degrees in 1 minute? If so, is the formula for this not (TAS / 10) + 7, not + 5 as in the article?

Do people really perform gyro-less turns using a calculation method as described in the article? Surely timed turns at three seconds per 10 degrees with a fudge for rolling-in/out are much simpler? I ask because this is the way they're taught in the UK.

Finally, "When the aircraft is at any altitude above the earth's surface the compass will tend to dip towards either the North Pole when in the northern hemisphere": the author's wording of this implies that there is no dip at the surface. This is not so. Possibly this is something that the author did not intend to imply.

Yes, a standard rate turn is 3 degrees per second = 180 degrees per minute = 360 degrees in 2 minutes. I've also heard this described as a 'two-minute turn'. My Jeppesen manual says that the formula is indeed (TAS / 10) + 5.

I've been taught to make no-gyro turns both ways (calculation and time), and for me, the timed-turn method is far simpler. I guess it's a personal thing.

Gentlemen I've corrected this article as follows: 1. Removed turn coordinator as directional instrument, because the TC is not one. 2. Added some to magnetic dip effect description. 3. Corrected compass lead/lag info and expected error angle. 4. Standard turn explanation added. 5. Given formula for standard turn is useful when turn coordinator or turn-slip indicator fails.

I suggest that the title of this article shall be changed. It encompasses more than turns and more than turns made with magnetic compass. Or perhaps it shall be split.Slawomir123
