Landing Signal Officer Trainer

Customer: Naval Air Warfare Center Training Systems Division (NAWCTSD)

User: U.S. Navy

ASI was selected by NAWCTSD to provide a Block Upgrade to the Landing Signal Officer Trainer (LSOT) located at NAS Oceana, VA. The LSOT, Device 2H111, provides training to Landing Signal Officers (LSOs) in simulating the carrier aircraft recovery environment and process via a visual system and a simulated LSO station consisting of a Heads-Up-Display (HUD) unit and Base Station console. The trainer consists of a host computer and peripherals, an instructor operator station (IOS), visual system (wraparound screen, background projection system, target projection system (with servo motion system), image generator (IG) computer), and trainee station, which are all linked via Ethernet with additional Input/Output (I/O) via the speech recognition system (SRS), communications system, and sound generation system to provide an immersive training environment.

The Landing Signal Officer (LSO) Trainer, Device 2H111, is located at the LSO School at NAS Oceana, Virginia and supports training for the Initial Formal Ground Training (IFGT) course, Advanced Formal Ground Training (AFGT) course, and the Fleet Replacement Squadron (FRS) Training Command (FRS/TRACOM) course. The 2H111 provides a safe, controlled environment for concentrated, hands-on LSO training (individually and team training) without endangering aircraft, personnel, or flight support equipment. The 2H111 allows LSO trainees to practice coordination procedures as well the introduction to the complex concepts involved in the recover of combat aircraft aboard an aircraft carrier. The 2H111 possesses the capability to simulate a wide variety of emergency conditions and malfunctions as required by the training scenario and to accommodate the level and complexity required for the training being conducted. The objective of the LSOCBT is to support the training objectives of the Initial Formal Ground Training course. The trainer consists solely of Commercial-Off-The-Shelf components, including a Central Control Complex and 16 student stations which are networked together. Central to this system is the interactive courseware that is inherent in the training system, including a courseware authoring capability. Ten lessons are available, including lessons pertaining to glideslope geometry, effects of wind, aircraft characteristics, FLOS/LSO equipment, field arresting gear, shipboard arresting gear, and steam catapults.

ASI designed, developed, produced, and installed the upgrades and are currently in final testing. This update included moving the trainer to an alternate location on base and providing a new classroom environment with interactive computer system adjacent to the trainer. The trainer modifications included a new visual image generator system and upgraded databases, a new host and IOS computer system, a new Instructor Operator Station, a new Trainer I/O system, and a Visual LSO Workstation (VLW).

The following LSOT systems were developed and/or integrated by ASI:

  • Aerodynamics
  • Flight Controls
  • Aircraft systems
  • Communication System
  • Computer System
  • Visual System
  • Computer Based Training System
  • Navigation System
  • Trainer I/O
  • Instructor / Operator Station
  • Aural Cue System

ASI also provided Program Management and Logistics Support services to support the successful completion of this program.

About the LSO

In the U.S. Navy, carrier operations began with USS Langley (CV-1) in 1922. Because pilots approaching the short, narrow deck had a poor view of the landing area, an officer was assigned to stand portside aft, facing the incoming plane, and holding colored flags to signal corrections. With standardized signals, the landing pilot could be informed whether he was at the correct altitude, course, and speed, leading to a “cut” signal to reduce power and land the airplane. In a properly executed landing, the aircraft’s tailhook snagged an arresting wire that brought the plane to an abrupt halt. Because LSOs used colored paddles well into the jet age, the officers are still known as “paddles” or “wavers”. From the late 1950s, carriers evolved from the original straight or axial-deck configuration into the angled deck, with landing signal mirrors or lenses providing correct glide slope information to the pilot.
