Thank you for purchasing the Piper Cheyenne by Digital Aviation and Aerosoft.
We hope that you will have as much fun with it as we had while creating it. For
many years, the Cheyenne series of business aircraft was one of the most successful for Piper. It started in the mid sixties, when Piper decided to redesign its
pressurized model „Navajo” to accommodate propeller turbines as propulsion.
On August 29th 1969 the prototype took off for his maiden ight, but it took
almost another ve years until the rst production aircraft went into service. The
control surfaces and ight controls had to be reworked several times, because
the higher speeds were a strain to the cell. Furthermore, a ooding of Pipers pro-
duction facility in Lock Haven delayed deliveries.
On October 22nd 1973, the maiden ight of the rst production aircraft Piper
Cheyenne PA31T took place – powered by two Pratt&Whitney PT6A-28s engines,
developing 620hp each. When Piper expanded the family in 1978 with a decreased variant (PT6A-11, 500hp), they renamed the initial aircraft in „Cheyenne
II” and the new variant became “Cheyenne I”. Improvements like more power,
redesigned cowlings and a new interior lead to the „Cheyenne IA”. In addition to
that, Piper stretched the Cheyenne II and built in a fourth cabin window. Equipped with PT6A-135s (750hp) engines and an increased MTOW by 180kg/400lb
– this variant became the „Cheyenne IIXL”. In total, 823 Cheyennes had been
built, 526 Cheyenne and Cheyenne II, 215 Cheyenne I and IA, and 82 IIXL, when
the production was discontinued in the mid eighties. Even twenty years later, the
PA31T models have an excellent reputation for being spacious, uncomplicated
and reliable aircraft and therefore enjoy great popularity.
Our add-on features all four mentioned variants, each in three liveries from different countries. All models possess a highly detailed 2D-panel with various view
options, a completely functional 3D cockpit with virtual cabin, two different
sound sets and of course a true to the original model with many ground objects,
like Ground Power Unit, towing equipment, chock blocks and pylons. The in-

strumentation is an exact rendition of its real counterparts, based on the „Silver
Crown Plus” avionics suite by Bendix-King. Autopilot is either the KFC250 or the
KFC300 by Bendix-King, depending on the model you choose. The pressurization
controllers are models by Dukes and Garret. A conguration program is provided
to help with individual settings.
And now we wish you many pleasant hours with our Piper Cheyenne Add-On for
the Microsoft Flight Simulator.

Saving your settings
Your conguration settings may be either saved to disk using the SAVE button
(3) or applied to the currently loaded aircraft only, using the button EXIT (4).
When using the SAVE option, the aircraft CFG le of the selected aircraft will be
also updated, to pertain the changes for the next time you start Microsoft Flight
Simulator. Using the button DEFAULT all conguration options are reverted to
their default values, while RANDOM (2) creates a random aircraft loading.
Options
The OPTIONS section in the upper left part of the conguration manager offers
some advanced conguration options:
5: Cold and Dark
Loads the aircraft in a „cold & dark” conguration next time. All systems are
off, and you may work through the complete startup procedure.
6: Show yoke in VCSelecting this option displays the yoke in the virtual cockpit also. You may
want to deselect this option to get easier access to some switches near the
yoke.
7: Show analogue VSI (no TCAS)Selecting this option displays an analogue vertical speed indicator instead of
the default digital one. In this case no TCAS is available.
8: Show HSI 3D objects in VCDeselecting this option displays the HSI as a 2D object instead of a 3D object
in the virtual cockpit. This may increase performance on low-end systems.
Also, it may be necessary when adding a third-party HSI instead of the su-
pllied one.
9: Show Radar 3D objects in VCDeselecting this option displays the radar as a 2D object instead of a 3D ob-
ject in the virtual cockpit. This is necessary if you want to add a third-party
weather radar at this place.
10: „Active Noise Reduction” (ANR) Sound Set
When using the ANR sound set, the internal engine sound is greatly mufed,
as the pilot would hear it while wearing Active Noise Reduction (ANR) head-

phones. Almost all pilots wear these or similar headphones today in order to
protect their hearing and ease communication over the radios. It is very rare
to see these aircraft own without the pilot and passengers wearing head-
phones.
NOTE: After changing the sound set the aircraft needs to be manually reloaded.
Weight and Balance
The Weight and Balance section (11-13) offers the possibility to individually con-
gure the loading and seating of the aircraft. The forward and aft baggage
compartments may be loaded in steps of 10 lbs., and different crew members and
passengers may be placed in any available seat:
Children: 60 lbs.
Women: 135 lbs.
Men: 170 lbs.
Please note that for the pilot and copilot seats, only men or women may be selected.
A detailed weights listing (18) is displayed just below the load editor. If the loading is within limits, the TOTAL WEIGHT value is displayed in green. Overweights
are displayed in red.

BASICS OF OPERATION
Panel operation
Microsoft Flight Simulator traditionally depends heavily upon mouse actions to
operate buttons, switches and knobs. Sometimes, click spots may not be 100%
intuitive, or the result of your action may depend upon clicking with the left or
right mouse button at the correct location. When familiarizing yourself with the
panel, it is suggested that you turn on „tool tips”. These tips will then appear
when you hold your cursor over the various click spots, and the tips will describe
what each click spot is for. Tool tips can be activated under the FS menu under
Options / Settings / General.
The Piper Cheyenne uses a consistent, standardized approach to operate the different controls in the aircraft panels. Following is an overview about these methods to interact with the controls in the 2D and 3D panels:
Push buttons: Left or right-click to operate these buttons on/off.
Guarded buttons: Guarded buttons require two steps: First, right-click to open
or close the guard covering the control. Second, left-click to operate the button
underneath. The cursor will show a solid hand.
Multi-position switches: Multi-position switches have more than one position,
and may be turned left/down or up/right. Left-click to move the switch to the left
or down, and right-click of right/up movement.
Page 12
Aircraft Operation Manual
Piper Cheyenne I, IA, II, IIXL
For ight simulation use only
NOTE: You can always use your mouse wheel to operate a multi-position switch.
Knobs with one level: Knobs are rotated left/right, or may be rotated completely
around. Left-click to rotate the knob to the left, and right-click to rotate the knob
to the right anywhere in the click spot. The cursor will be an unlled hand.
+
Some knobs also allow rotating them in larger steps. One example is the heading
bug, which may be rotated in steps of 1 or 10 degrees left or right. In this case the
cursor changes to a hand with „+” or „-” in it. When the cursor shows a „-”, the
knob will rotate to the left, while a „+” will rotate it to the right. Left-clicks will
rotate in low increments, while right-clicks will rotate in high increments.
hi lo
Knobs with two levels: Some instruments contain knobs with an inner and an
outer ring. In this case, the click area is further divided into a left and a right
part. Clicks in the left half of the click spot rotate the outer knob, while the
right half adjusts the inner knob. Note that the operation rules for one-level
knobs still apply.

NOTE: You can always use your mouse wheel to rotate a knob.

Aircraft model operation
Several hotkeys are available to operate animated parts of the external model
and the virtual cabin. Plase note that you need to assign keystrokes to some of
these functions in order to execute the animation. Keystrokes can be assigned via
the „Assignments” menu option in the OPTIONS => ASSIGNMENTS menu in MS
Flight Simulator.
Main passenger door: SHIFT-E (Standard key for doors in Flight Simulator)
Front baggage door: Wings fold/unfold
Aft baggage door: Tail hook extend/retract
Desks in virtual cabin: Click on a desk to fold/unfold it
External objects: Chocks, external power unit, tow bar etc. will
appear when the following conditions are met:
• parking brake set
• Prop controls: STOP
• Engines OFF

FREQUENTLY ASKED QUESTIONS (FAQ)
VOR/GPS Switch operation:
As soon as the NAV1 radio is tuned to a valid ILS frequency, the VOR/GPS switch
changes to VOR and the autopilot to NAV ARM mode. If a valid ILS frequency is
in range, the autopilot will follow it´s localizer beam. Valid ILS frequencies are
between 108.10 and 111.95 and the decimal part starts with an odd digit: 108.10,
You need to follow the engine start procedure as described (see PDF on your CDROM). CTRL-E will not work.
Panel and cabin lights (virtual cabin)
Due to limitations in Microsoft Flight Simulator, the panel instruments light and
the virtual cabin light are tied together. They can´t be operated independently.
Autopilot and ight director operation
Activation of the autopilot requires the ight director to be active. Always check
that you have turned on the ight director before activating the autopilot.
Trimble GPS airports, navaids and waypoints selection
Display of available airports, navaids and waypoints in the GPS is restricted to a
2000nm radius around your aircraft position.
Trimble GPS keyboard entry mode
If keyboard commands don´t seem to work at all, make sure SCROLL LOCK is
switched off, because all keyboard inputs will be intercepted by the GPS as long
as SCROLL LOCK IS ON.
Cold & Dark state
After loading in cold & dark state, wait some time for all engine instruments to
show zero before you begin any startup procedures. We strongly suggest load-
ing the Cheyenne from the default „Trike over Friday Harbour” situation every
time!

The Piper Cheyenne offers two ways to access the cockpit: A classic 2D cockpit
view, and a 3D virtual cockpit view. By default, Microsoft Flightsimulator X will
load the aircraft in 3D virtual cockpit view.
In classic 2D panel view, 5 different instrument panels are provided: Normal
view, approach view, landing view, IFR view, VFR view and copilot view. In addition, Microsoft Flightsimulator X provides a Mini-panel view and a view mode
where no panel is displayed. Cycling through this view is achieved using the W
(forward) and SHIFT-W (backward) keys. Please note that it is not possible to use
a joystick´s coolie hat to access the panel views in 2D mode.
