DISCLAIMER AND WARNING
IMPORTANT - Please read this disclaimer and warning carefully and review
the ALTA Aircraft Flight Manual (AFM) prior to flight. If you have any questions, please
contact [e-mail] prior to using the ALTA. You can review the most
current version of this AFM at www.freeflysystems.com/software-manuals/.
By using ALTA, 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, and for any direct or indirect consequences that may result from its use. You
agree to only use ALTA for proper purposes that are in accordance with local and
airspace rules and regulations.
»ALTA 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 helicopter, ALTA 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
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. Novice pilots should never fly without the supervision
of an experienced pilot.
»Always check ALTA and its components prior to operation.
»Always maintain a safe distance from ALTA when in use.
»Never attempt to touch ALTA when the propellers are moving.
»Never fly ALTA 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 when in
use and when changing configurations.
»Always remove the propellers or power ALTA using a low power source
when making a change to the configuration of ALTA to prevent propeller
strikes in the event of unintentional motor starts.
»Always remove the configuration jumper when making changes to the
configuration of ALTA.
»Always test ALTA 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 will be uncontrollable and dangerous.
»It is your responsibility to perform a full system check of ALTA prior to
every flight.
»It is your responsibility to learn how to safely operate ALTA and to adhere to
all applicable rules and regulations.
»Fly at your own risk.

INTRODUCTION
ALTA is a professional multi-rotor aircraft designed for demanding
cinematic, television, and photographic applications. Within five
minutes, ALTA 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 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. 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.
