Description

UH-60A UH-60L Black Hawk Operator’s Manual TM 1-1520-237-10 – 2019 Base, Change 2

The UH-60A and UH-60L operator’s manual is a detailed operating reference for the utility tactical transport helicopter configurations covered by TM 1-1520-237-10. The base technical manual is dated 31 January 2019 and this PDF incorporates Change 2 dated 31 March 2022. It brings together the information an operator needs to understand aircraft systems, operating restrictions, loading and performance, mission equipment, normal procedures, and emergency actions in one extensive reference.

The manual describes the UH-60A/L Black Hawk as a twin-turbine-engine, single-rotor helicopter used for tactical transport of troops, supplies, and equipment, with additional missions identified in the manual including medical evacuation, cargo, reconnaissance, training, and disaster-relief support. Propulsion coverage includes the T700-GE-701C and T700-GE-701D/CC engines, along with the fuel, lubrication, starting, engine-control, anti-ice, indication, and related systems that support their operation. The document also explains differences and designator-specific information for the UH-60A and UH-60L where applicable.

Aircraft Systems and Operating Information

This UH-60A UH-60L Black Hawk Operator’s Manual TM 1-1520-237-10 – 2019 Base, Change 2 gives substantial system-level coverage before moving into operating limitations and procedures. The aircraft and systems chapter explains the cockpit and cabin arrangement, landing gear, doors and windows, crew and troop provisions, emergency equipment, engines, fuel system, flight controls, hydraulic and pneumatic systems, powertrain, rotor groups, utility systems, environmental-control equipment, electrical power distribution, auxiliary power unit, lighting, flight instruments, and servicing subjects.

Engine coverage goes beyond a simple description. The manual identifies the T700 engine as a modular front-drive turboshaft and explains its cold section, hot section, power turbine section, and accessory section. It covers the engine fuel supply system, hydromechanical unit, digital and enhanced digital engine controls, ignition, alternator, bleed-air and anti-icing systems, oil system, starting system, speed and torque control, instrumentation, and associated cautions and operating indications. The T700-GE-701D/CC is identified in the manual as a replacement for the T700-GE-701C on the UH-60L while retaining the performance basis described for that configuration.

Flight-control and hydraulic information is similarly detailed. The manual describes cyclic, collective, and directional controls; mechanical mixing; pilot-assist servos; stability augmentation; trim; flight-path stabilization; the stabilator system; primary and tail-rotor servos; and the independent No. 1, No. 2, and backup hydraulic systems. System descriptions are supported throughout the manual by aircraft arrangement drawings, cockpit and console diagrams, engine illustrations, control diagrams, logic diagrams, and system schematics.

Avionics, Mission Equipment, and Crew Systems

The avionics chapter covers communication, navigation, transponder, and radar equipment, while the mission-equipment chapter addresses mission avionics, armament, cargo handling, mission-flexible systems, Air Warrior equipment, Blue Force Tracking, and the encrypted aircraft wireless intercom system. The manual also includes cockpit controls and instrument layouts, caution and advisory indications, and operating descriptions that help the reader connect individual controls with the systems they command.

Cargo and personnel information is integrated with operational planning. The manual includes troop seating and restraint provisions, cargo-loading material, mission-equipment loading, center-of-gravity information, and the weight-and-balance data needed to support aircraft loading calculations. This makes the UH-60A and UH-60L operator manual useful not only for system familiarization but also for preparing the helicopter for a specific mission configuration within the stated limits.

IMAGES PREVIEW

Operating Limits, Performance, and Procedures

Operating limits are organized into system, power, loading, airspeed, maneuvering, environmental, and other restrictions. The performance sections then provide the planning data used with those limits. Chapter 7A includes maximum torque available, hover, cruise, optimum cruise, drag, climb and descent, fuel flow, airspeed-system characteristics, and special-mission performance material. These sections are intended to support mission planning and aircraft operation using the conditions and charts supplied in the manual.

Normal procedures cover mission planning, operating procedures and maneuvers, instrument flight, flight characteristics, and adverse environmental conditions. Mission-planning material specifically ties together limits and restrictions, weight and balance, loading, performance, required publications, flight planning, and crew or passenger briefings. Emergency procedures are organized separately for aircraft systems and mission equipment, giving crews a dedicated reference for abnormal and emergency situations after the systems and normal operating logic have already been established in earlier chapters.

Taken together, these chapters make the UH-60A/UH-60L operator’s manual a broad operational reference rather than a single-system handbook. It moves from aircraft description and system function into the limits, loading data, performance information, normal operating procedures, and emergency procedures needed to use that system knowledge in practical flight and mission planning.

Important Distribution Notice

This manual states that it contains technical data whose export is restricted under the laws cited in the document. It also carries Distribution Statement D, which authorizes distribution to the Department of Defense and DoD contractors only due to Critical Technology and directs other requests to the Commander, U.S. Army Aviation and Missile Command. Obtain and use this document only if you are authorized to receive it under the restrictions stated in the manual.

Use the Manual as a Working Operator Reference

The UH-60A UH-60L Black Hawk Operator’s Manual TM 1-1520-237-10 – 2019 Base, Change 2 supports aircraft familiarization, mission planning, loading and performance work, system operation, normal operating sequences, and response to abnormal or emergency conditions using the procedures, limitations, cautions, charts, and system descriptions provided for the covered configurations. Having the correct model-specific operating data matters because helicopter limits, control logic, engine indications, loading constraints, and emergency actions must be applied exactly as specified for the configuration being operated.

For eligible and authorized recipients, this product is supplied as an instant PDF download after payment, with no physical shipping. The file can be opened on compatible computers, tablets, and phones and printed where permitted, giving the operator or technical reader a practical digital reference for the UH-60A and UH-60L.
