General information for
M-346 and T-50 (1)
• M-346 is a trainer by design. KAI T-50, by comparison, is
actually a fighter-bomber simplified to be a trainer.
• The T-50 program has expanded beyond a trainer concept to
include the TA-50 light attack aircraft, as well as the FA-50
multirole fighter comparable to KF-16.
• Both M-346 and T-50 are an advanced and lead-in fighter
trainer.
• Both offer a modern glass cockpit, with HOTAS, color multifunction displays, advanced navigation and communication
suites and avionic architecture representative of front line
aircraft.
• All have an 8G limit, although the T-50 and M346, being flyby-wire, will probably have the edge on G-onset and agility.

General information for
M-346 and T-50 (2)
• T-50 (6354kg) is significantly heavier than M-346 (5200kg).
• The M346 is twin-engined – potentially greater reliability, but
also greater cost.
• The M346 is subsonic and cold power only; the T-50 has an
afterburner and is supersonic.
• The service life is announced 10,000 hours by both. (The
official durability testing validate the 8,334-hour design
service life of the T-50 in 2004.)
• Maintenance man-hours per flight hour is 4.0 hours for M346.
• KAI said that the T-50's Mean Flight Time Between Failure
(MFTBF) is 5.97 hours (MFTBF for F-16C/D is 2.58 hours),
with Maintenance Man-hours per Flight Hour (MMH/FH) of
5.2 hours (F-16C/D Block 50/52 - 10 hours).

General information for
M-346 and T-50 (3)
• “The T-50 is more similar to an advanced F-16, the M-346 is
much friendlier to an inexperience pilot.” (by Aviation week and
space technology 07/04/2011)
• Avionics integration, life cycle cost and mission specifics may
favor M-346.
• The multifunctional use of T-50 could be a minus point, if
there are large enough to operate single-purpose trainer.
• Both offer embedded onboard training capability, “in flight”
embedded training system is defined for M-346 while no
evidence for T-50.

Helmet Mounted Display & Virtual
avionics of M-346
The M-346 cockpit is designed as a modern glass cockpit, and (left).
The avionics represented in the cockpit employ embedded 'virtual
avionics' realistically representing advanced systems including radar,
targeting systems, electronic warfare and other avionics, without the
need to carry such expensive systems on board, or simulate a training
combat-like environment in the real world. Yet the pilot can practice
using these systems as part of regular flight training, based on input
provided on board or from other aircraft or participants, networked
training environments
2014/8/13
13
The Advantage of M-346
• It is designed to the latest “design-to-cost” and
“design-to-maintain” concepts, with avionics
modeled upon those of fifth-generation combat
aircraft.
• Modular avionics architecture to integrate new
systems/equipment, sensors and weapons,
providing significant growth potential.
• 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.

14
The Disadvantage of M-346
• With external Gun pod, an externally carried gun
pod was less effective than an internal gun.
• Its pilot uses a centre-stick to command a digital
fly-by-wire control system, would conflict with MFD
equipment space and designing the ejection seat .

Embedded Training System of T-50
T-50's embedded training system (ETS) has
been developed by Korea Aerospace
Industries, Ltd. (KAI) using the embedded
virtual avionics (EVA). KAI ETS contains
several functions of simulation for the airto-air and air-to-ground combat training. In
the architecture of KAI ETS, the
target/threat database is the main
component of the ETS. Virtual sensors,
equipments, and weapons can share the
data of target/threat from one source,
virtual target/ threat database. EVA data
messages for embedded training are
transmitted to mission computer (MC) via
MIL-STD-1553B card. The interface between
the EVA card and MIL-STD-1553B card is
used for the TCP/IP communication
mechanism over Ethernet.

The Advantage of T-50
• High technology and performance: Consider the weapon,
performance, and supersonic capability. Golden Eagle can as
a light strike fighter.
• Commonality: T-50 is based on F-16. T-50 can perfectly a
LIFT aircraft for F-16MLU. Also, reduing the aircraft type is
the major concern. So training and striking in the same
aircraft is obviously a good idea.
• T-50 had excellent interoperability with the current F-16s.
• Electronically linked sticks – the instructor can “feel” the
students’ movements and make suggestions or corrections as
required
• Digital flight controls – enable us to “detune” the aircraft,
limiting pitch, angle of attack and role rate, to make it even
easier for the student to transition from the T-50.

27
The Disadvantage of T-50
• “The T-50 is more similar to an advanced F-16, one officer
tells Aviation Week. He adds that “the M-346 is much
friendlier to an inexperienced pilot.” The T-50 also has the
advantage of supersonic speed, compared to the transonic M346.
• Lower mission life (8,334 hours) compared with M-346
(10,000 hours) with higher Maintenance Man-hours per
Flight Hour (5.2 hours) compared with M-346 (4 hours).

Special concern for ETS
• ETS is the most cost

capability for modern
trainer and fighter.
• USAF developed similar ECATS and accomplish the
flight test for F-16 MLU.
• The similar capability also
defined in F-35.
• USAF T-X program define
similar capability as KPP.

ETS for LIFT and Benefit for F-35
•
“…Several ‘Super Teams’ have been formed to compete for the T-X
program. One such value addition is the induction of Virtual
Training System (VTS) for Embedded/Constructive training during
the advanced stage of LIFT. RFIs have been floated but the issue has
been dormant after that. One such Embedded Training System (ETS)
has just been contracted by the Israel Air Force from Elbit in
support of its acquisition of the M-346 aircraft. More about
Embedded Training will be discussed later.”

Main Messages
 To make ET a success, a two-pronged perspective is
required:
 ‘Training Needs’ perspective
 ‘Systems Engineering’ perspective
 With ET, the improved efficiency of new training
development approaches can be capitalised.
40
Embedded Training -- compared with -Live-Virtual-Constructive (LVC) training
 ET = uncomplicated version of LVC

without the virtual (V-) elements:
– no ground-based man-in-the-loop simulations
 ET contains LC


Live (L) elements
– actual aircraft
Constructive (C) elements
– Software models, computer generated:
 Forces
 Battlefield conditions
 No complex LVC organisation necessary

ET = less personnel, assets and costs.
ET Benefits
 ET provides realistic training ‘any time anywhere’
 ET system is fielded and maintained concurrent with
the operational equipment
 reduced need for:



instrumented training ranges
‘live’ assets, replaces ‘red air’
other training equipment
 reduces:


