SR-71a for FSX based on AlphaSim SR71a freeware 3D model.
Optimized for FSX Deluxe.  Minimal testing on FSX APac.  
There may be unknown problems and operation/behavior 
may differ greatly from documentation when using APac 
including possible wheel instability on the ground.
APac uses staged AB while Deluxe uses variable AB.
The Deluxe variable AB is more true to the real plane.

Distribution NOT compatible with earlier versions of 
Flight Simulator.

Requires full FSX realism setings for accuracy and 
enjoyment.  Please read the full manual which comes 
with this distribution for insight on how to fly this 
model effectively.

Payware version of FSUIPC strongly advised for better weather 
control.

Requires advanced pilot skills.  Experienced F-18 and 
Concorde pilots will learn quickly from the similarities, 
especially the high pitch landing typical of delta wings.

Custom Sound Pac using FSX advanced sound techniques.

Custom panel uses a combination of downloaded gauges 
from various sources, FSX default, and custom XML gauges 
providing features unique to the SR-71.  Not fully visually 
accurate.
These advanced features include:

o Realistic Compressor Inlet Temperature gauge and 
failures associated with over-heating.

o Eight fuel tanks positioned and quantity near 
actual with auto COG balancing system.  When fueled 
properly on the ground, pilot intervention is minimal.

o Detailed Annunciator system with pilot assist.

o Special gauges for FSX dual-seat shared aircraft.

o EGT gauges conformed to real-world values.

o Auto-moving Spike and unstarts possible.

o Detent afterburner throttle with detent shut-down.

o TEB usage and counter.

o Oxygen and pressurization systems.

o Air Refueling system at real world rates.

o Fuel Dump.

o Cabin Pressure Dump.

o EAS speed hold in addition to FSX autopilot with 
autothrottle.

o 3D panel fully populated with gauges.

o Optional radar for offline flying with AI traffic.

o Realistic electrical system.

o Onboard descent calculator for effortless descents 
from 80 thousand feet within 325 miles range at mach 3.2.

o Drag Chute fully implimented.

o Weather Pressure Change Monitor assists pilot in 
pro-active weather flying.


Flight Model:

o Accurate performance including climb, power profile, 
fuel rates and endurance when real world procedures are used.
Full stop to 28K ft and Mach 0.90 in 3 minutes.  3500 miles 
unrefueled range.  With air refueling, model can fly around 
the world non-stop in 11.5 hours.  US California KBAB to London 
Farnborough EGLF in 5.5 hours with three air refuelings.
Palmdale California to Dulles Int WA DC in 2 hours unrefueled.
Take off on the US East coast and land on the West coast two clock 
hours before you took off!  Chase and pass the Sun!

o EAS speed hold for 350 KEAS and 400 KEAS climb and normal 
descents.

o Conforms to real world lift and trim in all modes of flight.

o Works with default FSX Jeppeson online weather system.

o Several viewpoints provided.

o Spectacular afterburner effect with smoke.

o Spike position influences flight efficiency and possibility 
of inlet compressor unstarts.  Not just for looks.

o Custom Inti-Skid system.

o Wheels heat up from hot taxi and excessive roll and breaking.


Other Features:

o Detailed flight and operation manual with illustrations.

o Flight plans and saved FSX Deluxe flights for 
reproducing California to London and London to California 
world record flights with detailed instructions in spreadsheet 
form for reproducing these flights accurately.  See if YOU 
can match or beat the speed records using the exact same route 
and procedures the real pilots used.

o Detailed specifications and checklist Kneepad files.

o Pitch, Roll, and yaw stable through all historically 
accurate flight profiles as long as weather is realistically 
suitable for flight, fuel is loaded properly, and pilot follows 
documented procedures and limitations.

Thousands of hours of testing over five years of  
development to perfect the flight dynamics.  This is not a hack 
using modified flight models of other planes.
