A quick mental-math tool pilots use in the cockpit

A standard rate turn completes a full 360-degree turn in exactly 2 minutes - a turn rate of 3 degrees per second used as the reference standard for instrument approaches and holding patterns.

Worked example

For 120 knots true airspeed:

Bank Angle = (120/10) + 7 = 19.0 degrees bank

This "TAS/10 + 7" formula is a widely taught pilot rule of thumb, close enough to the more complex exact trigonometric relationship to be genuinely useful for quick mental estimation in the cockpit without needing a calculator or reference chart during instrument flying.
