Standard-Rate Turn Bank

Rule-of-thumb bank angle (degrees) for a standard-rate (3° per second) turn from true airspeed in knots.

Formula

ϕ≈TAS10+7\phi \approx \dfrac{TAS}{10} + 7

Variables

\phiBank angle (deg)
TASTrue airspeed (kt)

Example

TAS 120 kt: φ ≈ 12 + 7 = 19°

Did You Know?

A standard-rate turn takes exactly two minutes for 360° — the basis of timed instrument procedures.

True Airspeed (rule of thumb)

Basic

Quick estimate: true airspeed increases about 2% per 1000 ft of altitude above indicated airspeed.

Ground Speed

Basic

Ground speed is true airspeed adjusted for the headwind/tailwind component.

Flight Time

Basic

Time en route equals distance divided by ground speed.

Fuel Required

Basic

Total fuel needed is the fuel-burn rate multiplied by flight time.

Rate of Climb

Basic

Vertical speed is the altitude gained per unit time (ft per minute).

3-Degree Descent Rate

Basic

On a standard 3° glide path, required descent rate (fpm) is roughly ground speed (kt) times 5.
