DISCLAIMER AND WARNING
IMPORTANT - Please read this disclaimer and warning carefully and review
the ALTA User Manual 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 User Manual at www.freeflysystems.com/software-manuals/.
By using the 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 the ALTA, and for any direct or indirect consequences that may result from its
use. You agree to only use the 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, the 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
User Manual and a flight simulator are no substitute for training with an
experienced pilot, particularly when it comes to learning how to safely
operate the ALTA. Novice pilots should never fly without the supervision of
an experienced pilot.
»Always check the ALTA and its components prior to operation.
»Always maintain a safe distance from the ALTA when in use.
»Never attempt to touch the ALTA when the propellers are moving.
»Never fly the 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 the 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 the ALTA to prevent propeller
strikes in the event of unintentional motor starts.
»Always remove the configuration jumper when making changes to the
configuration of the ALTA.
»Always test the 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 the ALTA prior to
every flight.
»It is your responsibility to learn how to safely operate the ALTA and to ad-
here 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 User 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.

WARNING
Warnings are used to highlight proce-
dures which, if not strictly observed,
may result in personal injury or loss
of life.
CAUTION
Cautions are used to highlight proce-
dures which, if not strictly observed,
may cause damage to equipment.
NOTE
Notes are used to highlight specific
operating conditions or steps of a
procedure.
SPEED TERMINOLOGY
GS Ground Speed is the speed of an
aircraft relative to the ground
TAS True Airspeed is the airspeed of an
aircraft relative to undisturbed air
METEOROLOGICAL TERMINOLOGY
ISA International Standard Atmosphere in which:
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);
The temperature gradient from sea level
to the altitude at which the temperature is
-56.5°C (-69.7°F) is -0.00198°C (-0.003564°F)
per foot and zero above that altitude

10| USER MANUAL
MSL Mean Sea Level is the average height above
the surface of the sea for all stages of tide

the aircraft above the ground
OAT Outside Air Temperature is the free air static
temperature surrounding the aircraft
Pressure Altitude Altitude measured from standard sea level pressure
(29.92 in. Hhg) by a pressure or barometric altimeter
