During a constant airspeed descent, the vertical speed indicator (VSI) shows a 500 foot-per-minute descent rate and the groundspeed is 90 knots. Approximately how many nautical miles will the airplane travel while descending from 4,000 feet MSL to 1,000 feet MSL?

During a constant airspeed descent, which flight instrument provides the primary indication for maintaining airspeed?

You are in straight-and-level flight at 90 knots indicated airspeed. Power is reduced to initiate a descent while maintaining 90 knots constant airspeed. What pitch attitude change is indicated on the attitude indicator?

Proper instrument cross-check technique during a constant airspeed descent emphasizes
