What This Manual Provides

This is not a short quick-reference booklet. The UH-60A UH-60L EH-60A Black Hawk Operator’s Manual TM 1-1520-237-10 walks through every major aircraft system on the Black Hawk, from the T700 engine and its fuel, oil, ignition, bleed-air and anti-icing subsystems to the main transmission, intermediate gearbox, tail gearbox, rotor heads and blades, hydraulic and pneumatic systems, electrical power supply and distribution, heating and ventilation, lighting, flight instruments and avionics. The opening systems chapter is followed by chapters covering avionics (VHF-FM, VHF-AM, UHF-AM, HF, secure voice, Doppler/GPS navigation, VOR/ILS/marker beacon, IFF transponder and radar altimeter), mission equipment (armament, cargo hook system, rescue hoist, extended range fuel system, external stores support system, volcano mine delivery, medevac kit and other flexible mission packages) and the full operator limits section that defines what the helicopter is cleared to do.

Performance Data, Limits and Procedures

Chapter 5 lays out the system limits, power limits, loading limits, airspeed limits, maneuvering limits, environmental restrictions and other limitations. Chapter 6 contains the weight/balance and loading information including fuel moments, personnel moments, cargo hook moments, rescue hoist moments, stowage compartment moments and the center of gravity limit charts. Chapters 7 and 7A are the performance data section split by engine variant, so operators flying T700-GE-700 powered aircraft use Chapter 7 while T700-GE-701C powered aircraft use Chapter 7A. Both cover maximum torque available, hover, cruise, optimum cruise, drag, climb and descent, fuel flow, airspeed system characteristics and special mission performance. Chapter 8 covers normal procedures, mission planning, preflight, engine start, runup, hover check, takeoff, landing, parking and shutdown. Chapter 9 is the emergency procedures chapter covering engine failures, fires, loss of tail rotor thrust, hydraulic system malfunctions, electrical system failures, smoke and fume elimination, fuel system emergencies, ditching and flight control or main rotor malfunctions.

Avionics, Mission Equipment and Special Coverage

The avionics chapter breaks down communications, navigation and transponder/radar equipment with operating procedures for the intercommunication system, VHF-FM sets, VHF-AM sets, VHF-AM/FM sets, UHF-AM sets, HF radio, voice security equipment, direction finder, VOR/ILS/marker beacon receivers, Doppler and Doppler/GPS navigation, integrated inertial navigation, gyro magnetic compass, transponder and radar altimeter. The mission equipment chapter covers the M60D 7.62 mm machinegun installation, cargo hook system with emergency release circuit tester, rescue hoist system with cable shear, chaff and flare dispensers, radar signal detector, infrared countermeasure sets, heads-up display, ASE status panel and the external extended range fuel system. The UH-60A UH-60L EH-60A Black Hawk Operator’s Manual TM 1-1520-237-10 also includes the diagram sets that technicians rely on: general arrangement drawings, cabin interior views, upper and lower console layouts, instrument panel layouts, engine module diagrams, hydraulic logic module operation charts, airspeed operating limit charts, hover and cruise charts, autorotative glide distance charts, exterior check diagram, emergency exits and equipment diagrams, and the mooring diagram.

Who This Manual Is For

This operator’s manual is aimed at the pilot, crew chief, mission equipment operator, maintenance technician and flight-line crew who need to reference correct procedures, systems descriptions, limits or performance figures for a UH-60A, UH-60L or EH-60A. Because it is written as an operator-level technical manual, the systems descriptions, limits and procedures match the way the helicopter is actually operated and serviced, and the emergency procedures are the same ones taught on the aircraft. Where a step, limit or value differs between the three airframes or between the two engine variants, the manual spells that out.

Coverage Across Three Airframes and Two Powerplants

Because this single document covers the UH-60A, UH-60L and EH-60A together, you get the shared airframe and systems content plus the model-specific differences in one file. The UH-60L content reflects the T700-GE-701C engines and the improved durability gearbox, while the UH-60A and EH-60A content reflects the T700-GE-700 installation and the EH-60A-specific electronic mission systems, cabin arrangement and mission equipment. The Chapter 7 and Chapter 7A split makes it easy to jump straight to the performance data that matches the engines on your airframe. Change 9, dated 19 April 2002, is the latest change included in this revision, so the procedures, limits and system descriptions reflect the state of the manual at that change level.

How This Manual Helps You Do the Job

With this manual in hand you can plan a mission using the correct performance data for your engine variant, compute weight and balance and verify the center of gravity stays inside limits across the flight, brief a crew using the mission planning and crew briefing guidance, run a complete preflight and exterior check in the correct order, start and run up the engines using the published sequences, work through the hover check and before-takeoff checks, plan cruise and optimum cruise for the engine variant installed, and troubleshoot and respond correctly when something fails in flight. It gives the mechanic and the crew the system descriptions, limits and torque values needed to keep the helicopter inside its envelope, the diagram set needed to identify components and routing, and the emergency procedures needed to recover safely from an in-flight malfunction. The fuel moments, personnel moments, cargo hook moments and stowage moments sections let you build a real loading plan instead of guessing.

Why the Right Reference Matters

The UH-60 family has narrow operating envelopes, published power limits, weight and balance limits and airspeed limits that change with gross weight, temperature and pressure altitude. Using the wrong torque value, the wrong rotor speed or the wrong CG figure can put the aircraft outside limits. The correct procedures and specifications are the ones printed in the operator’s technical manual for the engine variant and airframe you are flying. This manual gives you those procedures and numbers for the UH-60A, UH-60L and EH-60A directly, in the wording used by the Army, with the diagrams and charts to back them up.
