What is the gyro suction range for operation below 15,000 feet?

Gyro suction range is the specific window of vacuum pressure that powers the vacuum-driven gyros (measured in inches of mercury). The gyros must operate within a mid-range suction: not too little, which would cause the instruments to become unstable or slow to respond, and not too much, which can over-stress the bearings and shorten gyro life. Below 15,000 feet, the system is calibrated for that middle range so the gyros stay accurate and reliable with the typical vacuum pump performance at that altitude. The other ranges are either too low or too high for stable gyro operation in this altitude band, so the mid-range window is the correct choice.
