Study Notes
3° per second — a full 360° in two minutes. Rule of thumb for the required bank: TAS divided by 10, plus half that result. At 100 knots that's 10 + 5 = 15° of bank. The turn coordinator's index marks show standard rate (IFH ch 7).
The attitude indicator is the control instrument for setting bank. Once established:
- Bank: turn coordinator (it confirms the rate).
- Pitch: altimeter.
- Power: ASI.
The ball keeps me honest on coordination (IFH ch 7).
Lead the rollout by about half the bank angle — with 15° of bank, start rolling out 7–8° before the target heading. Standards: altitude ±200 ft, standard rate maintained, rollout heading ±10°, airspeed ±10 kt.
Banking tilts the lift vector, so the vertical component of lift decreases. I add a touch of back pressure (and accept a slight airspeed loss) as I roll in, and release it as I roll out — small corrections off the altimeter, not big pitch swings (PHAK ch 5, IFH ch 7).
On north/south headings the compass leads or lags in turns — UNOS (Undershoot North, Overshoot South, northern hemisphere). Acceleration errors show on east/west headings — ANDS (Accelerate North, Decelerate South). That's why I turn to headings using the gyro heading indicator, set from the compass in steady, level, unaccelerated flight (IFH ch 5).
Timed turns: at standard rate I'm turning 3° per second, so a 90° heading change takes 30 seconds. Roll in, time it, roll out, then verify on the magnetic compass once wings-level and stable (IFH ch 7).
- Fixating on the heading indicator and letting altitude wander.
- Using too much bank — past standard rate it's easy to overshoot, and it aggravates disorientation.
- Uncoordinated rudder.
- Forgetting the rollout lead (IFH ch 6–7).
