A turn in which the clock and the turn coordinator are used to change heading a definite number of degrees in a given time is called:

• A. Threshold Crossing Height
• B. Timed Turn
• C. Torquemeter
• D. Time And Speed Table

Answer: (B)

A timed turn relies on using a clock together with the turn coordinator to achieve a precise heading change in a known interval. The turn coordinator shows how quickly you’re turning, and the clock tells you how long you’ve been in the turn, so you can hit the exact amount of heading change you’re targeting. In a standard-rate turn, you’re turning at about 3 degrees per second, which means you’ll cover roughly 180 degrees in a minute, 90 degrees in 30 seconds, and so on. Start the turn, maintain that rate with the turn coordinator, and roll out on the new heading when the timed interval ends. This approach focuses on timing the turn to reach a specific heading, rather than relying on bank angle or other cues. Other terms refer to altitude references, engine torque measurement, or navigation tables, not to turning by a set heading in a set time.
