2. 2. M-346The M-346 has been designed to provide the best possible balance between high training effectiveness and operational capabilities and low life-cycle cost. It is designed to the latest “design-to-cost” and “design-to-maintain” concepts, with avionics modeled upon those of fifth-generation combat aircraft. The M-346 exploits non-conventional features and advanced technologies to provide superior performance, flying qualities and safe operations. These characteristics, together with the man-machine interface and the advanced mission management suite offered by its Embedded Tactical Training Simulation (ETTS), make the M-346 truly representative of next generation combat aircraft. In addition the M-346 performance level, flight characteristics and on-board systems offer significant capabilities also in operational roles.
3. 3. INTRODUCING THE M-346 ADVANCED & LEAD-IN FIGHTER TRAINERM-346 characteristics contribute to maximize its teaching effectiveness and to allow flight hours to be downloaded from Operational Conversion Units. In addition, the aircraft is also ideally suited to potentially satisfy the “Companion Trainer” requirement at reasonable cost. In its training role the M-346 has been conceived as the “core” of an Integrated Training System (ITS) which includes : Training Delivery System- Aircraft with built-in ETTS- Synthetic Training (Full Mission Simulator and Part Task Trainer)- Academic Training (Computer Aided Instruction and Computer Based Training)- Mission Handling (Mission Support Station to define training mission and support briefing and de-briefing phases)o Integrated Logistic Support Training Requirements- Training Needs Analysis (TNA)o Training Management Information System (TMIS)INTRODUCING THE M-346 OPERATIONAL CAPABILITIES From the beginning of the program, the M-346 has been conceived with additional operational capabilities, with the goal of providing a very capable multirole combat aircraft, particularly suited to ground and surface attack roles including CAS(Close Air Support), COIN (COunter INsurgency) or anti-ship missions as well as air police missions.Among the characteristics which make the M-346 an effective combat platform are:o the structure designed to carry up to three tons of various weaponso nine stores stationso an aerodynamic configuration which allows the integration of a wide range of external storeso provision for multi-mode radaro survivability built-in to the aircraft basic designo large fuel capacity for enhanced combat persistenceo remarkable speed and maneuverability even when fully armed or with one engine inoperative
4. 4. M-346 TECHNICAL DESCRIPTIONAerodynamics – the M-346 introduces aerodynamic solutions previously found only on fighters. Wing LERXs (Leading Edge Root eXtensions) generate vortexlift, while computer-controlled leading edge flaps offer variable camber wings. These solutions enhance aerodynamic efficiency, maneuverability and high angle of attack flight. Differential all-moving horizontal“tailerons”further increase controllability, particularly at high angles of attack. This is complemented by the engine air intakes, placed under the LERX and canted upwards, to provide distortion-free airflow to the engines in all flight attitudes. Flight Control System – Quadruple-redundant, self-reconfigurable in case of failure, Full Authority Digital Fly-By-Wire.The Flight Control System (FCS) has fouridentical flight control computers at its core. In conjunction with its peculiar aerodynamics, the FCS endows the M-346 with flight characteristics similar to the latest fighters.The FCS offers both manual (three-axis stability and control augmentation, carefree handling) and automatic (flight director and auto-pilot) capability. It also serves as a data exchange interface between the avionics system, back-up instruments and engine FADECs. The quadruplex architecture allows the M-346 to operate safelyeven after two consecutive failures.The reconfigurable FCS can be tailored to present students with progressive levels of dif-ficulty as they build up towards front line fighter characteristics: different limits of Angleof Attack, Maneuver Load Factor and Roll Rate can be selected, helping inexperienced pilots transition from basic trainers to combat aircraft. A Pilot Activated Recovery System (PARS, the so-called“panic button”) is fitted for auto-matic recovery from unusual flight attitudes. When activated it returns the aircraft to a level wings slightly climbing flight-path to allow the pilot to recover control.

1. 6. EMBEDDED TACTICAL TRAINING SIMULATION (ETTS)

A complete in-flight Embedded Tactical Training Simulation (ETTS) suite is a key M-346 feature and, in turn, the core element of an Integrated Training System (ITS). ETTS enables the M-346 to offer the whole spectrum of simulated training functions. ETTS provides student and instructor with the following simulations: An M-346-based ITS therefore requires no actual deployment of various air and surface threats, installation of expensive on-board sensors, carrying and firing of training weapons. This greatly reduces logistic and pilot training costs. In complex tactical training missions the ETTS makes possible the reduction or elimination of additional aircraft by replacing all or part of them with Computer Generated Forces (CGF), both friend and enemy. ETTS functions can support Stand Alone (flying a singleton mission) or multi-ship networked operations, with aircraft networked via a dedicated Training Data link to exchange Tactical Scenario data with other real participants. The M-346 ETTS design includes two embedded simulation areas: In-Flight Sensor and Scenario Simulation Embedded Simulation of Radar, EO/IR sensors, Electronic Counter Measures (ECM) and TacticalDatalink, to simulate a variety of tactical scenarios:Electronic Warfare (EW), threat warnings and active threats (such as surface-to-air missile bat-teries, anti-aircraft artillery, etc). In-Flight Weapons Simulation : Allows weapons training without employing actual weapons. Student pilots perform simulated attacks, in both Air-to-Air and Air-to-Ground weapon delivery modes, using representative symbology and specific weapon delivery parameters. On-board systems provide pilot scoring, in real-time or on ground for mission debriefing. PC-based Mission Support Station (MSS) used to create simulated scenarios during pre-mission planning, which are then loaded into the aircraft avionics system via a removable and re-programmable cassette; the MSS is also used for post-mission debriefing using data recorded in the cassette. 20,000 ft/0.65MN Radius 120 nm Total mission time: 80 min Training area: 40 min combat training, 0.4/0.9 MNConfiguration: 1 x SRAAM + 1 x AACMI PodConfiguration: 1 x SRAAM + 1 x AACMI PodAIR COMBAT MANOEUVRING TRAININGLOWLEVEL NAVIGATION Total mission time: 55 min (65 min)50 min NAV, (with 1 ext. tank: 60 min NAV)450 KCAS (0.7 MN) @1,000 ft CConfiguration: CLEANonfiguration: CLEANGENERAL HANDLING20,000 ft/0.654 T/GoMNRadius 120 nmCConfiguration: CLEANonfiguration: CLEANTotal mission time: 82 min Training area: 30 min aerobatics/general handling, 100/450 KC ASST AND - ALONE ARCHITECTURE NETWORKED ARCHITECTURE TRAINING MISSIONS   

1. 7. M-346 Operational CapabilitiesWhile maintaining its superior advanced/lead-in fighter trainer characteristics, the M-346 is easily field-reconfigured to become an effective combat aircraft. In this operational configuration the aircraft can perform ground attack, anti-ship and aerial target missions, particularly in the so-called “homeland defence” role. Even when carrying a full load, the armed M-346 maintains a high thrust/weight ratio (in fact, not far from that offered by fully armed frontline multirole fighters) and moderate wing loading, both of which contribute to excellent overall performance and maneuverability.Even with one engine inoperative, the M-346 is still capable of high speed and maneuverability. This translates into remarkable battlefield survivability. The large internal fuel capacity, complemented by up to three 630 l external tanks and a quickly removable air-to-air refueling probe, endows the M-346 with significant combat radius and/or patrol endurance further enhanced by the non-afterburning engines. Stores Management System data presentation and control functions run on any of the MFDs in either cockpits. HOTAS controls provide weapon system functions selection. Weapon aiming is provided by the central main processor, while aiming data are presented to the pilots through HUDs and, when installed, HMD. The nine stores pylons are equipped with pneumatic ejector release units to reduce maintenance. Sensors – The M-346 can carry a targeting pod and provides space to install radar to detect and track both aerial and surface targets. Defensive Aids Sub-System (DASS) – In addition to the survivability provided in the M-346 by design (non-afterburning/low infrared emission twin-engines installation, totally duplicated main systems and power sources, quadruple FCS computers and sensors, re-configurable flight control system in the event ofbattle damage, multi-path structure etc) the aircraft has the provision to install a number of dedicated survivability enhancement equipment: Radar WarningReceiver (RWR), Chaff & Flare Dispensers (CFD) and active Electronic Counter Measures (ECM) pod.
