DISCLAIMER AND WARNING

IMPORTANT - Please read this disclaimer and warning carefully and review
the ALTA 8 Aircraft Flight Manual (AFM) prior to flight. If you have any questions,
please contact support@freeflysystems.com prior to using the ALTA 8. You can review
the most current version of this AFM at www.freeflysystems.com/software-manuals/.

By using ALTA 8, you acknowledge that you have read, understand and agree to this
disclaimer. You agree that you are solely responsible for your conduct while using
ALTA 8, and for any direct or indirect consequences that may result from its use. You
agree to only use ALTA 8 for proper purposes that are in accordance with local and
airspace rules and regulations.

» ALTA 8 is not a toy and should be operated with extreme care, as improper

operation can cause damage to property, serious personal injury or death.

» As with any multi-rotor aircraft, ALTA 8 is a complex and technical

machine. Novice pilots should invest sufficient time on a flight
simulator and seek training from an experienced pilot prior to
operation. The ALTA 8 Aircraft Flight Manual and a flight simulator
are no substitute for training with an experienced pilot, particularly
when it comes to learning how to safely operate ALTA 8. Novice pilots
should never fly without the supervision of an experienced pilot.

» Always check ALTA 8 and its components prior to operation.

» Always maintain a safe distance from ALTA 8 when in use.

» Never attempt to touch ALTA 8 when the propellers are moving.

» Never fly ALTA 8 over or around people, power lines or other aircraft.

» Never fly with any propellers that have visible imperfections or damage.

» Always keep children and animals a safe distance away from

ALTA 8 when in use and when changing configurations.

» Only use propellers supplied by Freefly Systems

that are designed for use on ALTA 8.

» Always remove the propellers or power ALTA 8 using a low power

source when making a change to the configuration of ALTA 8 to
prevent propeller strikes in the event of unintentional motor starts.

» Always remove the configuration jumper when making

changes to the configuration of ALTA 8.

» Always test ALTA 8 with the propellers removed to make sure that the

motors are spinning in the correct direction and that the motor assignment
is correct with respect to the Synapse flight controller. If you have either
of these wrong, the ALTA 8 will be uncontrollable and dangerous.

7| AIRCRAFT FLIGHT MANUAL

» It is your responsibility to perform a full system

check of ALTA 8 prior to every flight.

» It is your responsibility to learn how to safely operate ALTA 8

and to adhere to all applicable rules and regulations.

» Fly at your own risk.

» ALTA 8 is a tuned system with custom components selected for each

application. Modification to, removal, or substitution of ALTA 8 components
will void the warranty and can lead to unsafe operating conditions.

INTRODUCTION

ALTA 8 is a professional multi-rotor aircraft designed for demanding
cinematic, television, and photographic applications. Within five
minutes, ALTA 8 can unfold from its carrying case to flying some of
the most capable cinema cameras on either the top or bottom of the
aircraft. The SYNAPSE flight controller is purpose-built for cinema
use, yielding precise yet smooth control.

This Aircraft Flight Manual has been prepared to describe the
complete operation of airframe and flight control systems, and the
normal maintenance of those items. Do not operate ALTA 8 without
reading and understanding this manual.

This manual is not a substitute for adequate flight training. Training
requirements can vary when operating in different countries or
under different flight conditions. Always consult local regulations
before flying ALTA 8. In areas where there are no flight training
requirements, it is the sole determination of the pilot-in-command
as to whether he or she has the appropriate level of training or
experience for a given flight. Always set and adhere to personal
minimums and fly within your own capabilities.

The air is a dry, perfect gas;

The temperature at sea level is 15°
Celsius (59° Fahrenheit);

The pressure at sea level is 1013.2
mbar (29.92 inches Hg);

MSL Mean Sea Level is the average height above

the surface of the sea for all stages of tide

AGL Above Ground Level is the height of

the aircraft above the ground

OAT Outside Air Temperature is the free air static

temperature surrounding the aircraft

11| AIRCRAFT FLIGHT MANUAL

Pressure Altitude Altitude measured from standard sea level

pressure (1013.2 mbar, 29.92 in. Hg) by a

ALTA 8 ALLOWABLE GROSS WEIGHT

As altitude and temperature increase, the density of the air decreases. Consequently, ALTA 8’s thrust will decrease. The

following table describes maximum gross weight limits with respect to altitude and temperature.

ALTA MOBILE APP

The ALTA App is used to configure ALTA 8 parameters, update ALTA 8 firmware,
and to monitor ALTA 8’s status during flight. To download the ALTA App, search for
“Freefly ALTA” in the App Store or on Google Play™.

Parameters may only be adjusted while ALTA 8 is on the ground and disarmed. In
addition, radio mapping parameters can only be adjusted when the Configuration
Jumper is removed. For more information on radio mapping, see the Radio Mapping
section of this manual.

The ALTA App will be actively maintained, and additional functionality may be added
over time. For information on individual app updates, refer to the App release notes.

NOTE

When making configuration changes with the ALTA App, wait
three seconds for the app to automatically save changes to
ALTA 8 before shutting off the app or the mobile device.

27| AIRCRAFT FLIGHT MANUAL

ADDITIONAL REQUIRED COMPONENTS (NOT INCLUDED)

RADIO CONTROLLER

ALTA 8 supports a variety of radio controllers as outlined in the Flight Controller
Specifications. A minimum of five (5) channels are required, with four (4) used for
flight control, and the remaining one (1) used for mode selection.

However, a radio controller with at least 10 channels is highly recommended to
make use of Velocity and Climb Rate Clamps, Return-to-Home (RTH), Disarm Safety,
and Orbit Mode functions. It is recommended to use a radio controller with a three
way switch for the Mode, Home, and Orbit functions, a two or three way switch for
the disarm safety function, and a knob or slider input for both the Velocity and Climb
Rate Clamp functions.

FLIGHT BATTERY

ALTA 8 can accommodate a variety of Lithium Polymer (LiPo) flight battery packs.
Battery packs must be 6S, having a nominal voltage of 22.2 V. Only run ALTA 8 using
two packs at a time. Each pack must have a continuous discharge rating of 250
amps or greater, and a peak discharge rating of 500 amps or greater. For additional
information on expected flight durations, refer to the Performance Section of this
manual.

28| AIRCRAFT FLIGHT MANUAL

SETTING UP ALTA 8

29| AIRCRAFT FLIGHT MANUAL

UNFOLDING ALTA 8

ALTA 8 features swan-neck booms that fold into a compact size for
travel. They are secured in an open position for flight using over­center latches.

TO UNFOLD ALTA 8

1. Remove ALTA 8 from case

2. Fold down all eight boom retention clips

3. Open ALTA 8 booms. ALTA 8 can become unbalanced and tip

over while unfolding booms individually, so unfold opposite
boom pairs simultaneously to keep balance.
