Hydraulic reservoir fluid level should be approximately which indicators on the sight gauge?

Explanation:
Hydraulic systems need a steady fluid supply with some headroom for expansion, so the reservoir is kept near the middle of its sight gauge range. On the MH-65E, the acceptable level is shown by the midscale or bullseye marks. Keeping the fluid around those indicators provides enough fluid for peak demands and temperature changes while avoiding overfill, which can cause foaming and venting. If the level sits too low, pump cavitation and inadequate hydraulic performance can occur; if it’s full, you’ve used up the space needed for expansion. So, align the reservoir to the midscale or bullseye on the sight gauge.
