As equally iconic as it's Air Force counterpart, the distinctive F-4 Phantom II was at the leading edge of carrier enabled power projection for the US Navy. Beginning in 1966 as a version of the F-4B upgraded to meet the requirements of the Navy and the Marines, 522 aircraft were designated as F-4J's. In 1977 the J was extensively upgraded and modernized to become the F-4S, with 302 airframes receiving the complete upgrade. Having served admirably for 20 years, the final active duty Phantom carrier launch took place in March of 1986.
Our award winning F-4J/S Phantom II package is, we feel, a brilliant aircraft simulation, but we intend to push that even farther. The capabilities of Microsoft Flight Simulator (and by extension, Lockheed Martin's Prepar3d) allow for a plausible simulation of the flight regime of most aircraft, especially when in the hands of a skilled developer. However, there are many limitations present in the base simulator platform that prevent a true study-level simulation.
As such, we are proud to announce our Advanced Series F-4J/S. This expansion is designed to overcome current limitations present in simulator-based flight dynamics and systems simulation to provide a truly definitive, true-to-life representation of the real aircraft. This expansion also integrates TacPack functionality in order to provide all full range of the Phantom experience.
External Flight Physics Engine
The Advanced Series F-4J/S expansion includes an external physics engine that is independent of the FSX/P3D simulator platform. This allows the recreation of accurate aircraft characteristics (including post-stall region) without the traditional limitations imposed by the default simulator engine. This extends to a highly realistic external engine model of the J79-GE-10B, reproducing accurate thrust output values across all RPM/throttle ranges, as well as accurate fuel consumption and engine characteristics.
Individually developed flight models for the F-4J and the F-4S are present, each with accurate stability and control derivatives based on wind tunnel and flight test data. This is translated in a realistic aircraft behaviour at all conditions (angle of attack=[-180, 180] / Mach=[0, +2]). Adding to this is an accurate drag model, proper slats aerodynamic effects, and highly developed boundary layer control effects with realistic representation of lift and engine thrust.
A realistic weight and CG model has also been implemented, with aircraft handling characteristics being realistically affected by loaded stores in terms of moments of inertia and and CG position. Correct CG management will need to be observed.
As a result of the combination of all of these features, the F-4J/S ADV model accurately matches the real jet performance figures in terms of maximum speed, acceleration, manoeuvring capability, range, for all possible configurations!
In-Depth Systems Modeling
A realistic F-4 Phantom Flight Control System (FCS) has been implemented in the ADV. It not only includes a 1:1 recreation of the real aircraft SAS (Pitch/Roll/Yaw), but also a model of the bob-weight and stick forces system. These last are implemented within the obvious limitations of non-forcefeedback hardware and programming. Individual control surface effects are modeled including actuators dynamics and other FCS specific elements.
A realistic Automatic Flight Control System (AFCS) has been modeled, including realistic AFCS modes, behaviour and limitations. including an implementation of the aircraft Automatic Pitch Trim. A realistic Approach Power Compensation System (APCS) has been modeled according to system technical description. This includes accurate system dynamics as well as operating limitations.
Aircraft individual hydraulic and pneumatic lines are modeled. Each aircraft element is accurately actuated, including element redundancy and backup systems. In case of a single (or multiple) line failure, the affected system(s) will behave as defined in the Flight Manual.
J79 engine operating characteristics and limitations are accurately modeled. Amongst others, the ADV includes the following features: realistic engine operating limits (engine core and afterburner), realistic engine startup including GPU aided or Cartridge start, realistic engine windmilling and midair starts, and realistic nozzle and inlet ramp behaviours. A realistic fuel system is implemented in the ADV. Both Automatic or Manual (realistic) fuel management is available.
A custom landing gear model has been implemented in the ADV version. This includes, amongst other things, an individual landing gear element structural damage model (landing gear strut and tyre), accurate nose wheel steering, and an accurate anti-skid system operation.
Custom Aircraft Carrier Dynamics
The F-4J/S ADV module also includes a custom carrier dynamics engine, with enhanced physics focusing on the catapult system and the arrestor gear system. In both cases, specific system limitations such as pneumatic power and mechanical resistance are taken into consideration, in order to allow for highly realistic carrier operations.
Custom & Configurable Failures
The F-4J/S ADV module allows a comprehensive system of aircraft failures, all able to be individually configured to suit any desired level of difficulty. Set to provide a fully realistic simulation experience, the failure capabilities will include not only realistic systems operation, but extend to cover the possibility of having a system failure with probabilities based on true failure rates. Individual or multiple failures timed events will be also available in order to recreate specific emergency situations.
Scalable Realism & Difficulty
Although we are proud of what has been accomplished with the F-4E ADV in terms of systems depth and flight modeling, we completely understand that on occasion you might not want all of that responsibility. After all, even students need a break now and then!
To that end, the realism of the included systems along with their associated limitations can be scaled from a 100% realistic experience with full system management under pilot control, all the way over to a easy / fail-free mode.
With maximum realism set and systems management under pilot control, there's no way around it: the Advanced Series F-4J/S is a very complex aircraft. Given all of this complexity, an "Instructor Mode" has been included. It can be selected to assist at any phase of flight operations, from engines start, to engines shut-down.
In this mode, everything from configuration changes and mis-operation warnings, right down to flying hints will be displayed just as if you had a real F-4 instructor sitting in your rear seat. Highly recommended during the familiarization period, this mode will help ease the learning curve typically associated with complex jets.
TacPack Integration Included
The F-4J/S ADV expansion comes complete with full TacPack integration, including all TacPack features applicable to the F-4 Phantom II, as well as realistic battle damage being modeled. The TacPack integration is 'smart'; TacPack features are only enabled if the TacPack software is installed. So while a functional TacPack installation is highly recommended, it isn't an absolute requirement. This enables the F-4J/S ADV module to continue to function if TacPack isn't desired, or simply not yet available for your choice of simulator platform.
Vertical Reality Simulations' TacPack software offers a stand-alone top notch weapons and warfare platform for Prepar3D. It is a payware product and is not included with your purchase from MilViz.
The Advanced Series F-4J/S module is not a stand-alone add-on. It extends the functionality of the MilViz F-4J/S Phantom II and as such, that aircraft is required for this release to function. The Advanced Series F-4J/S module does not function nor is it compatible with the MilViz F-4E.
