Credits

Project managers, Owen Hewitt and David Brice would like to thank the following people for their

invaluable contribution to this project.

Doug Dawson, for his kind permission to make use of his dsd_fsx_xml_sound3.dll audiocontroller (Prometheus_Sound.dll) as part of our products.

Jonathan Bleeker, for assisting in the development of the gauges. Jeremy Elliott, for pitching the original project to us and introducing us to Skip in the

beginning.

Larry Griffiths, for doing justice to Mirco Pecoraris artwork on Prometheus. Skip Stewart, for designing this fantastic aircraft which weve all come to love, and which

we hope weve done justice to, and allowing us all to feel like were Skip Stewart! Albeit in

front of our desktops!

About this Guide

This guide has been written to familiarize new users to the systems, operations and handling of the

IRIS Airshow Series Prometheusproduct.

It is essential that users have a working knowledge of Microsoft Flight Simulator and the theory of

flight PRIOR to running this product.

By reading and learning the Pilot Manual prior to flying and keeping it to hand during your flight for

reference, you will gain the most enjoyment from this product.

Tactile usage of switches and knobs in this productIn general, LEFT mouse-click places a switch AWAY from the pilot and a rotary selector COUNTER

CLOCKWISE.

A RIGHT mouse-click places a switch TOWARDS the pilot and a rotary selector CLOCKWISE.

In some circumstances this does not apply, but the majority of switches and knobs operate in this

fashion.

The Origins

Back in 2010 we were approached by a gentleman named Jeremy Elliott who kindly put us in

touch with Skip Stewart Airshows as part of a proposal to design and build a virtual replica of Skips

fantastic modified Pitts S-2S Prometheus.

Last year as part of the project, we had the great pleasure in collaborating with industry giant

Owen Hewitt, responsible for many popular commercial and freeware products.

Owen brought Prometheus to life for us, whilst his colleague Larry Griffiths did a fantastic job on

Skips Artwork courtesy of Mirco Pecorari of AircraftSudioDesign and for that we owe them all aHUGE pat on the back.

All in all, were confident that Prometheus will give you hours of fun in the sky and will allow you all

to pretend to be one of the worlds finest aerobatic pilots. Even if it is just in front of a monitor!

Have fun flying her!

COCKPIT OVERVIEW

Getting to know the Twister, its avionics, cockpit, functions and switches is the key to your full

enjoyment of the Twister. We made every effort to reproduce the system as it is in real life based

on publicly available information.

Descriptions of the numbered controls displayed above:

(1) Elevator Trim handle A handle which when pulled upwards provides positive elevator trim,

and when pushed down provides negative elevator trim.

(2) Propeller Pitch handleA handle which when pulled adjusts the pitch of the propeller.

(3) Throttle handleA handle which when pushed forward increases the engine power, and when

pulled back, reduces engine power.

(4) Smoke System switchA switch which toggles the display smoke system on or off.

(5) Mixture handleA handle which when pulled toward the pilot will richen the fuel/air mixture in

the engine, and when pushed forward will lean the fuel/air mixture to the engine.(Note: Skips Prometheus mixture handle acts in reverse to most mixture handles dont get

caught out!)

Instrument Panel

(1)AccelerometerThe accelerometer measures the G-Force on the aircraft from -5 to +12.(2) Airspeed IndicatorThe airspeed indicator measures airspeed in miles per hour (mph) from

0 to 250 mph.

(3) Altitude IndicatorThe altitude indicator displays the aircrafts barometric altitude in feet.

(4) Stall Warning Light The Stall warning light will illuminate if the aircraft goes into a stall

condition.

(5) Blue Mountain Avionics EFIS Lite Currently offers a primary flight display and horizontal

situation indicator which is toggled by the use of the DISP button.

(6) System switchesAs follows (from left to right);

Left magneto/starter switch. Right magneto switch. Master battery switch. Engine alternator switch.

item is currently non-functioning. Please refer to the Grand Rapids E.I.S. for fuel status

information.)

OPERATING LIMITATIONS

This section specifies aircraft and engine limitations to be observed during normal operation of the

aircraft. They are derived from actual flight tests and demonstrations.

The most restrictive limitation applies to any given condition.

AIRFRAME LIMITATIONS

The Silence Twister is designed for the following safe load factor;

+12 / -7g with 600kg take-off weight at a manoeuvre speed of 135 knots. It is not permitted to

exceed this load factor. It is to be avoided to do any manoeuvres at speeds above 135 knots.

(Note: Airspeed limitations of the Turbine Twister are decreased due to airframe adjustments,

please refer to the figures below for simulation requirements.)

Airspeeds above 135 knots are to be avoided in heavy turbulence.

AIRSPEED LIMITATIONS

Airspeeds are based on sea level conditions.

Minimum speed... ...52 knots

Maneuver speed... ...135 knotsCruising speed... ...135 knots

Maximum speed... ...175 knots

WEIGHT LIMITATIONS

Zero fuel weight (ZFW)... ...480 kg

Additional load... ...250 kg
