When using a view limiting device for straight and level flight, what are the requirements for heading, altitude, and airspeed?

The correct answer regarding the requirements for heading, altitude, and airspeed when using a view limiting device for straight and level flight aligns with real-world pilot training regulations. Specifically, when utilizing a view limiting device, the pilot must maintain a heading within 20 degrees from the intended course, an altitude within 200 feet of the desired level, and an airspeed within 10 knots of the target speed.

This level of precision is necessary to ensure that while a pilot may be operating under simulated instrument conditions, they still maintain a close approximation to the aircraft's intended path and performance dimensions. The requirements help develop the pilot's ability to control the aircraft effectively, even without direct visual references outside the cockpit.

Maintaining tighter limits, such as those indicated in the other options, is typically unnecessary for routine training exercises when the primary focus is on developing instrument flying skills. Adhering to the standard of within 20 degrees for heading, 200 feet for altitude, and 10 knots for airspeed encourages safety while allowing the pilot to practice essential skills without overly restrictive parameters.
