### Ground Control Station Assembly

This section of the manual describes the steps to properly assemble the ground

control station (GCS) for the Spektre. The operator should always follo w the

prescribed preflight checklist before every flight.

1. Inspect the GCS shipping case and ensure that all parts are present. If there

are parts of the GCS missing, do not fly.

2. Setup the GCS computer on a stable and clean surface.

3. Power on the GCS compu ter and ensure the battery level is adequate for

operations. If available, plug the computer into a power source.

4. Inspect the USB connection on the telemetry radio for FOD then p lug the

telemetry radio into the GCS computer

. 5. Place the telemetry radio up and away from obstructions that may block RF

signals.

6. Orient the antennas vertically and offset to each side, creating a “V” shape.

This will help ensure that the GCS antenna pola rity matches the aircraft while

in flight.

### Remote Video Terminal Setup

As there are many payload options for the Spektre; there are equally abundant

options for receiving the video on the ground. Generalized procedure s for setup

are listed below. For details about a specific part or component, please see the

manufacturers information sheets.

1. Inspect and inventory all parts of the Remote Video Terminal ( RVT ) system.

2. Setup t he video display on the mount provided with th e system. This could be

a tripod or table mounted display.

3. A video receiver (Rx) will be mounted to the display or integrated into the

display. The antennas will be inspected for FOD before being installed onto

the receiver. Orient the antennas in a manner that will allow for best

reception/ coverage.

4. Secure the battery or power source for the display and Rx.

5. Connect the power source to the display and Rx.

### Radio Control Transmitter (RCTx) Setup

The Spektre aircraft comes with a r adio control box that is used by the External

Pilot (EP) for manual control flight modes, autonomous mode augmentation and

flight abort procedures. As it is an integral part of the system and many flight

mo des are reliant on it, special care and handling is required. Setup procedures

are listed below and inspection points highlighted in figure 27

.

1. Inspect the radio ensuring that all switches and gimbals ( joy sticks) are

functional. Excessive dirt or dust tha t collects in the gimbal mechanism can

inhibit movement, which can cause control issues in manual flight mode(s).

2. Power on the radio and confirm that the internal battery is fully charged or

adequate for the length of operations.

3. As most modern RC transmi tters are capable storing information for multiple

models, the user must ensure that the correct model is selected. If the

incorrect model is active, the RC transmitter will not communicate with the

receiver on the aircraft side.

4. For safety and to prepara tion to arm the aircraft, set the throttle stick at the

lowest setting.

5. Set all moveable switches to the position furthest away for the user as he/ she

is holding the transmitter. This ensures that the flight mode and other

functions are in a preflight st ate. Figure 28 shows the RCTx switch functions.

Switches not listed are inhibited.

## Aircraft Launch Procedures

1. Determination of the wind direction is critical for launch. The aircraft should

never be laun ched downwind as it could cause a vortex ring state situation.

2. The AVO should once again verify that all the aircraft systems are within

acceptable limits.

3. For arming and safety, the aircraft should be in the Stabilize flight mode. The

EP will ver ify this on the RCTx and the AVO will confirm this in the MP HUD.

4. The EP will power the payload and check that is operational.

5. The EP will now clear all personnel from the launch area and disable the

safety switch. The safety switch will glow solid red wh en it is dis abled

. 6. If applicable, begin recording the sensor data on the onboard DVR.

7. The EP will power on the navigation lights at the time.

8. The EP will arm the aircraft by holding the left stick on the RCTx down and to

the right for >5 seconds. The prop ellers will spin upon arming. The AVO will

also see “ARMED” in large red text in the MP HUD indicating that the aircraft

is armed.

8.1. During the arming sequence, the Autopilot status LED will flash Red

- Blue

rapidly indicating that the gyros and barometric se nsor are being

calibrated. It is critical that the aircraft is not moving during this phase.

9. The AVO will now set the aircraft flight mode to AUTO by pressing the AUTO

button in the Actions Ta b. Confirmation of this is depicted in Figure 29

## Normal Operational Procedures

Flight L imitations:

• The air craft should not be flown in the proximity of high voltage power lines,

certain types of radar any other high power emitting devices.

• A thorough site survey should be accomplished before any flights occur.

Airspace and vertical obstructions should be well known and briefed prior to

flights.

• See Table 2

– Spektre Aircraft General Specifications for environmental

limitations.

• The AVO and/ or EP will not intentionally place the aircraft into a non

- normal

state of operation.

1. While in flight, the EP and obs ervers should not lose visual line of sight with

the aircraft. In the event of an airspace incursion, the EP will take manual

control of the aircraft and manually fly the aircraft to a safe airspace or

perform a flight abort procedure.

2. The AVO will monito r the aircraft’s system health and flight tracking during

normal operations. Large deviations in flight path tracking or altitudes may be

indicative of a system malfunction. If this is witnessed, the AVO will alert the

EP to take over manually.

3. The AVO wil l also ensure that the battery voltage doesn’t reach a state of low

voltage or a < 20% capacity. If a higher than normal battery depletion rate is

witnessed, the AVO will notify the EP to take over manually and land the

aircraft as soon as is reasonable.

4. As GPS is the primary source for position information and augments other

sensors in the flight contr oller, a healthy GPS solution is critical. If the AVO

witnesses a state where the visible satellite count drops below 5 or th e HDOP

raises above 2.5, he wil l notify the EP so t he aircraft could take n over

manually.

5. Proper communication between the AVO, EP and other flight crewmembers is

crucial for sufficient situational awareness during flight operations. It is also

important to ensure a “sterile cockpit” s o communications are not inhibited in

any way.SPEKTRE OPERATIONS M AN.

## Aircraft Failsafes and Non

- Normal Flight Procedures

In the event of a state of emergency, or non

- normal flight, the AVO and EP shall

perform the fo llowing procedures to mitigate risk of damage to personnel,

property or the aircraft itself. It is imperative that the flight crew first establishes

that the aircraft is flying and navigating well. If not, communication between the

flight crewmembers and n on

- crewmembers must cease.

1. Aircraft Battery Failsafe

The battery failsafe can be setup and changed in the mandatory hardware tab

under the Initial setup window. The operator has the option of setting a low

voltage and/ or a capacity reserve (mAh) that will trigger the failsafe when the

threshold is met. Characterization of the discharge curve will be necessary to

establish viable threshold numbers.

– REV. A 51 3. Geo

- Fence Excursion

The geo

- fence function provides t he operator with an invisible ceiling and/ or

horizontal wall that prevents the aircraft from continuing on excursions outside of

the specifications of the fence. The dimensions of the fence are user adjustable

with the ceiling being measured from the grou nd altitude relative to the aircraft

when it is armed (0 AGL), to the ceiling or altitude specified. The horizontal walls

are built in a circular fashion radiating outward from the point of where the aircraft

is armed and are also adjustable by the operato r.

In the event of a fence breach the failsafe function will engage per the operator’s

settings as noted in the table below. It is possible for the operator to attempt

manual control of the aircraft after the geo

- fence failsafe has been activated and

in t hat case a backup fence is erected 20 meters further out and up from the

original fence. If the aircraft continues on a trajectory away from the HOME

position and the backup fence is breached, the failsafe will once again become

engaged.

The operator is given every opportunity to regain control of the aircraft before an

uncontrolled landing is commanded; however, in the event of a rouge flight where

the aircraft cannot be commanded HOME, the aircraft will be forced to land once

it reaches 100 meters dista nce out from the original fence wall.

5. Telemetry/ GCS Link Failsafe

If the link between the GCS and the aircraft is lost the airc raft will activate the

GCS failsafe based on the operator’s settings. The aircraft will not return to the

mode it was in before the loss of communication; however, and the operator will

have to change the flight mode out of the failsafe flight mode to reta ke control.

– REV. A 53 6. RCTx Link Failsafe

The operator has the option to set a failsafe function that is activated when the

contact between the radio controller (RC) and the RC receiver is lost. There are

several scenarios where the RC signal can be lost and the func tion of the failsafe

will change accordingly:

## Aircraft Recovery and System Disassembly

Extra awareness is required during the recovery phase of flight. It is best practice

to ensure that non

- flight crewmembers are clear of the recovery area during

recovery.

1. The AVO will c ommand the aircraft to RTL and begin the landing sequen ce or

this will happen automatically if a RTL command point is built into the flight

plan.

2. The EP and observers will ensure visual line of sight throughout the recovery

phase of flight.

3. When the aircraft touches down, the EP will lower the throttle stick to it’s

lowest setting to ensure that the autopilot disarms the motors.

4. The EP will arm the safety switch on the aircraft. The switch will flash when

armed (in safe mode).

5. Power down the payload and navigation lights at this time.

6. Remove power to the air craft by disconnecting the aircraft battery.SPEKTRE OPERATIONS M AN.

## Appendix

Appendix A

- Flight Mode Description

There are multiple flight modes available in ArduCopter 3.2; however, there are

four primary modes us ed in normal mission profiles. These fligh t modes are

described in table 15

.

Table 15

- Flight Mode Descriptions

STABILIZE Stabilize mode is what can be considered closest to manual flight

mode and what would be used in an emergen cy recovery when the

aircraft is in visual LOS . Stabilize automatically levels the vehicle and

maintains the current heading, while allowing the pilot full control over

the throttle and axial control up to the bank angle maximums.

LOITER In loiter mode; the vehicle maintains a consistent location, heading,

and altitude. This can be adjusted by using the sticks on the pilot

handheld controller:

• Horizontal location can be adjusted with the Roll and Pitch

control stick.

• The aircraft heading can be set with the Yaw control stick.

• Altitude can also be adjusted with the Throttle control stick

operating as a variable rate control

.

RTL In return to launch (RTL)

mode , the copter navigates

from its current position to

hover above the home position.

The behavior o f RTL mode can

be controlled by several

adjustable parameters.

AUTO In autonomous (A uto) mode

, the vehicle will follow a pre

programmed mission script

stored in the autopilot, including

autonomously navigated

waypoints, commands, and

events.SPEKTRE OPERATIONS M AN.
