    Study Notes

    Hydraulic Systems Introduction

    • The aircraft has two independent hydraulic systems: primary and utility.
    • Both systems are similar but not identical, with separate and shared functions.

    Primary Hydraulic System

    • Provides hydraulic pressure to the primary side of all four flight control servoactuators.
    • Consists of a hydraulic pump, manifold, and servoactuators.
    • The primary hydraulic pump is mounted on the left side of the transmission accessory gearbox.
    • The pump is a constant pressure, variable displacement design, driven by the transmission accessory gear train.

    Primary Hydraulic Manifold

    • Stores, filters, and regulates the flow of hydraulic fluid.
    • Has mechanical dirty filter indicators for visual inspection on both manifold pressure and return sides.
    • The return filter has a bypass valve.

    Hydraulic System Controls

    • Operation of the hydraulic system is automatic except in emergency situations, tail wheel locking/unlocking, and rotor brake activation.
    • Hydraulic system indications are displayed on the ENG and SYS pages.
    • The primary hydraulic system failure will result in the loss of BUCS and SCAS functionality.

    Tail Wheel Lock

    • Utility hydraulic pressure is used by the tail wheel lock actuator to unlock the tail wheel.
    • The tail wheel can be locked or unlocked from either crew station via the TAIL WHEEL panel or collective grip tail wheel button.

    Hydraulic System Indications

    • PRI/UTIL/ACC PSI: 0 - 6000 psi displayed in increments of 10.
    • Yellow warning: 3410 - 6000 psi ≥ 5 seconds, red with box: ≥ 5 minutes.
    • Red with box: 0-1250 psi.

    Pneumatic Systems

    • The IPAS (Integrated Pneumatic System) pressurizes, regulates, and distributes air to various systems.
    • The primary pneumatic power source is dual engine bleed air.
    • The secondary source is single engine bleed air.
    • APU bleed air is used to start main engines during aircraft power-up.

    IPAS Control

    • Control of IPAS is an integrated function provided by mission processors and the Electrical Power Management System (EPMS).
    • The A/C UTIL page and HIT page provide BLEED AIR 1 and 2 on/off buttons.

    Helicopter Operations

    • Establish and announce a forced landing or single engine flyaway plan when operating at an OGE hover
    • Maintain ground track within 3 feet, constant rate of movement for existing conditions, and constant rate of turn during OGE hover

    In-Flight Operations

    • Maintain heading ±10 degrees, ground track alignment with minimum drift, and altitude ±100 feet
    • Maintain airspeed ±10 knots and rate of climb or descent ±200 feet per minute (FPM)
    • Maintain trim ±ball width and acknowledge low altitude warning audio

    Crew Responsibilities

    • Both crewmembers are responsible for performing crew coordination actions and announcing malfunctions or emergency conditions
    • PC (Pilot Command) duties include briefing specific duties before entering the helicopter, maintaining airspace surveillance, and applying environmental considerations
    • Copilot/Gunner (CPG) duties include assisting the PC and performing additional tasks as required

    Hover Power Checks

    • Initial hover power check should be completed at the beginning of the flight IAW Task 1038 (IGE power available and environmental conditions permitting)
    • Hover power TQ (percent [%] TQ) baseline can be determined using PERF page (CUR, PLAN, or MAX mode) calculations
    • Environmental and load considerations will be applied throughout the flight

    Situational Awareness

    • Situational awareness information will be provided to each crewmember through their individual HDUs
    • PC will approve instances when it may be desired not to employ the HDU during the conduct of the mission or a specific flight maneuver

    Altitude Definitions

    • Minimum Safe Altitude (MSA) is defined as the minimum safe height above the surface or obstacles to which the helicopter can descend in a masked condition
    • Minimum Maneuvering Altitude (MMA) is defined as the altitude above the mask or barriers at which the helicopter may safely hover### AH-64 MTL
