## CAUTION Always neutralize control inputs when switching between control modes. 

## NOTE ALTA’s emergency control modes are for emergency use only. Do not test or use emergency control modes in normal flight conditions. 

# CONTROL MODES ALTA has three primary flight control modes: Manual Mode, Height Mode, and Position Mode. They are selected with the Mode Switch. ALTA also has two emergency control modes, Return-To-Home and Autoland, which are available only during certain situations. For additional information, refer to the sub-section associated with each emergency control mode in the AFM. MANUAL MODE In Manual Mode, ALTA will only stabilize its attitude. At neutral control input (middle pitch and roll stick position), ALTA will attempt to remain level. Throttle control is direct. HEIGHT MODE Height Mode changes the throttle stick behavior to command climb and descent rates. The higher the throttle stick position, the faster ALTA will climb. Conversely, the lower the throttle stick position, the faster ALTA will descend. When the throttle stick is centered, ALTA will enter Height Hold. In Height Hold, ALTA will maintain a target altitude and try to correct for drift. If a disturbance moves ALTA away from this target altitude, ALTA will climb or descend to return to the target altitude.

### 14 

# CONTROL MODES [CONTINUED] POSITION MODE Position Mode changes the pitch/roll stick behavior to command ground speeds. Pitch and roll stick deflection will command fore/ aft and left/right ground speeds respectively. Controlling altitude in Position Mode is the same as in Height Mode. With pitch and roll controls centered, ALTA will enter Position Hold. In Position Hold, ALTA will maintain its position over a given point on the ground and correct for disturbances. Position Mode requires a strong GPS signal. If a weak signal is present, ALTA will not enter Position Mode, and if the GPS signal degrades while in Position Mode, ALTA will automatically revert to Manual Mode. RETURN-TO-HOME Return-To-Home Mode will command ALTA to fly back to the starting point of the flight or the last defined Home Point. When ALTA first acquires a GPS position, it sets this as the Home Point of the flight. The Home Switch on your radio controller can also be used to set a new Home Point. See Channel Mapping in the User Manual for more information on setting up the Home Switch. RTH can be initiated manually by the Home Switch or be initiated with an LOS event. When initiated with the Home Switch, ALTA will fly back to the Home Point, and the pilot will maintain control of ALTA’s altitude the entire time. ALTA will not autoland if adequate signal is detected. The pilot can 

## CAUTION Flight using Position Mode in areas of degraded GPS signal, such as near buildings or under dense tree cover, is not recommended. The reversion to Manual Mode can sometimes cause abrupt changes in flight behavior. cancel the RTH procedure by commanding a pitch or roll command. During an LOS event, ALTA will first check its current altitude against Safe Height. If it is lower, it will climb to Safe Height, and if ALTA is above Safe Height, it will remain at its current altitude. Next, ALTA will fly back to the home position at the RTH Speed set in the ALTA App. Finally, upon reaching the home position, ALTA will begin Autoland. AUTOLAND The Autoland function will command ALTA to hover for 10 seconds and will then land in place. If ALTA is above the app-configurable Safe Height setting, ALTA will first descend to it at the Maximum Descent Rate. After reaching this height, ALTA’s descent will slow to the Autoland Descent Rate. Autoland will only initiate if one of the following conditions is met: • During Loss of Signal (LOS) if Autoland is selected as the LOS event

in the ALTA app • At the end of a LOS Return-to-Home event • Battery exhaustion while flying in Height or Position modes only

# ALARMS ALTA will notify the pilot of critical alarms using the Status Light. These alarms indicate a serious issue have been observed in the behavior of the ALTA that, if not acted upon immediately, can cause loss of control. Never continue a flight when ALTA indicates an alarm. During an alarm, the Status Light will turn red. 

## WARNING If ALTA displays an alarm, land immediately.

### 21 

# COMPASS CALIBRATION ALTA features a highly sensitive 3-axis magnetometer that measures the earth’s magnetic field to infer heading. Occasionally, the compass will require calibration, especially when traveling between different geographic locations. TO PERFORM A COMPASS CALIBRATION: 1. Secure a battery onto ALTA (see page 18-19) 2 . Plug in the battery 3. Open the ALTA App 4. Select Configurations > More > Compass 5. Under Calibration, select Start Manual 6. Follow the on-screen instructions 

## WARNING Verify ALTA is disarmed prior to performing a compass calibration. To ensure ALTA does not arm, remove the Configuration Jumper, set the mode switch to Height or Position, or set the home switch to Set New Home Position. 

## NOTE It is recommended to use two people to perform the compass calibration as it requires handling and rotating ALTA. Perform calibration without a payload attached. 

## NOTE Ensure a microSD card is installed in the GPS/compass module prior to performing compass calibration.

# SETTING HOVER THROTTLE Hover Throttle is an app-configurable parameter that adjusts ALTA’s thrust at center throttle stick and ensures ALTA does not climb or descend at the center stick position while flying in Manual Mode. A Hover Throttle setting that is too high or too low can cause ALTA to climb or descend when switching between Manual Mode and Height Mode. Adjust the Hover Throttle setting by entering a stable hover in Manual Mode. Note the stick position, or have an assistant view the radio chart in the ALTA App to determine stick position. If ALTA hovers with the stick below neutral, decrease the Hover Throttle until ALTA hovers with neutral stick input. If ALTA hovers with the stick above neutral, increase the Hover Throttle until ALTA hovers with neutral stick input. 

## NOTE Hover Throttle will need to be adjusted when changing the overall weight of the system, or when moving between very different elevations. 

## NOTE The ALTA App does not allow Hover Throttle adjustments while ALTA is flying.

# TUNING ALTA ALTA comes pre-tuned for a wide variety of payloads and flying conditions. Generally, additional tuning is not required to fly ALTA, and additional tuning will only need to take place if more customization of control feel is desired. For more information on tuning parameters, refer to the ALTA Aircraft Flight Manual. 

## WARNING Tuning can change the fundamental flying characteristics of ALTA. It is possible for ALTA to become unstable or even uncontrollable if values are set too high or too low. Only change tuning parameters in small increments and with caution. Always test new tuning configurations in open areas away from people or obstacles.

# FAILSAFE AND LOSS OF SIGNAL FUTABA S.BUS AND SPEKTRUM/JR DSM When using Futaba receivers with S.Bus or S.Bus2, or using Spektrum or JR receiver satellites with DSM2 or DSMX, the Synapse Flight Controller can detect signal strength and a loss of signal event. Setting failsafes in the receiver is not necessary, as failsafe behavior is set in the ALTA App. The radio’s failsafe settings will not be used. PPM RECEIVERS When using a receiver with a PPM output signal, the Synapse Flight Controller will not automatically detect loss of signal and will follow the radio controller failsafe commands typically set during the bind process. Refer to your radio controller manual for information on setting up failsafes. 

## WARNING Improperly set failsafe settings on PPM radio receivers can cause unexpected flight behaviors if ALTA loses radio control signal. After setting radio failsafe settings, ensure they are correct by viewing the channel mapping parameters in the radio configuration screen in the ALTA App, or viewing radio charts in the ALTA App. Ensure that the radio commands behave as expected when the radio controller is powered off.

### 35 WE RECOMMEND THE FOLLOWING FAILSAFE SETTINGS: 1. Throttle: Neutral 2. Pitch/Roll/Yaw: Neutral 3. Flight Mode Switch: Position Mode 4. Home Switch: Return to Home
