What parameter sets the timeout after which the aircraft will enter return mode without a connection to the GCS?failsafe parameterWhat throttle percentage do you need on the DATX to maintain cruise speed/altitude?50%What visual cue are you using to align your aircraft on the XY centerline? You may wish to use a screenshot from your recorded video.The aircraft should look as if it's heading straight for you.How often are you looking at SPAS?a quick 3-6 second glance.Describe how the Believer aircraft would fly if the battery were placed farther aft than the CG?The aircraft would not be stable in flight. In a 30° bank, what inputs are required to maintain altitude?yaw and pitchAt what angle does the Believer need to be launched?30 degreesWhen switching from stabilized to auto mode, what must be set on the GC to ensure predictable waypoint behavior?Set the next waypoint.
Open File Explorer and navigate to C:\temp.Open WindRacers Sim + GCS Startup.bat This should open each of the simulator elements: FCU, X-Plane, and GCS.In the X-Plane window, select “New Flight”.Double-click Purdue University to select a runway. To change X-Plane settings at anytime, click the airplane icon in the upper right to return to the main menu.
As required, set the weather by clicking “Customize” in the weather pane. Set the height (top), speed, and direction of a wind layer. Click “Done”, then “Start Flight” to begin. You will adjust the weather in .
To set the camera position to the side of the runway, perform the following steps in order.Hit shift + 3 Hold shift and use the left arrow to complete 1-2 outward spirals. Align to the runway edge by using the left arrow or the right arrow as needed.
Connect your phone to the local internet (Anesti or Rose will help with this).In Ground Control, navigate to Settings > Connection > Ground Control.Enter the entire server IP address into your phone’s web browser. It should look like http://192.168.1.XXX:8001
On your phone, navigate to Safety Pilot via the burger bar in the upper-left corner.
Set DATX to safe state.Power on the DATX.Confirm the model is X-PLANE.Switch to Taxi Mode.Connect the USB Mini to the rear port.Select “USB Joystick”
In ground control, create a standard circuit that includes:Takeoff pointLanding pointPattern altitude of 700 AGLKidney bean shapeRepeats indefinitely
Fly the mission from takeoff to landing.Pay attention to:The airspeed at takeoff.The position and height of the downwind to base turn.The position and height of the base to final turn.The position at which the aircraft enters a flare.The touch-down point.
Set up the aircraft for a stabilized takeoff.Back taxi (in taxi mode) sufficiently so that the aircraft is airborne by the time it reaches your position. Brakes off, switch to stabilize.Be sure to input 100% throttle.Steer using the rudder.At takeoff speed, apply the appropriate elevator input.Stay in the circuit until your aircraft’s energy is balanced for cruise (62 kts).Pitch for speed, throttle for altitude.When ready, come in for a landing. Use the following as suggested targets (adjust as necessary)Target <60 kts on downwind to base, deploy 50% flaps.Begin descent. Target altitude set in auto circuit.Turn base to final at XY point and target 55 kts.Deploy 100% flaps as needed.Maintain aircraft descent (the aircraft should not move up or down, but grow in size).Add throttle to pull the aircraft through if low; remove throttle if high.Flare ~10 feet above the runway and hold until touchdown.Touchdown in front of yourself.Steer with the rudder, and apply the brakes gradually.Repeat these steps as needed.

Lab 7
Tasks
Task 0 - Questions
Answer the following questions. Some questions can be answered after completing the lab.
Task 1 - DATX file upload
In AT209 we uploaded .yaml files to your DATX. We need another file on the controllers for the Sim
Please upload this file onto your controller to be able to use your DATX on X-Plane
model39.yml
7.4 KB
Once you upload this model to your DATX then you should select this model whenever you want to use X-Plane. (Model #40)
Task 2 - Simulator Setup
In the previous lab, we ran the simulator on separate computers with a GCS operator and a Safety Pilot. For this lab, you will serve as both, which will be more cognitively intensive, but more realistic to operating a sUAS on an autonomous mission.
On a designated PC (2 in COMP and 3 in PAAL), complete the following to initialize the simulator
Start FCU and X-Plane
Set Weather

Set Camera Position
Setup SPAS
Connecting DATX
Task 2 - Auto Circuit
It is important to understand how the autopilot works based on the assigned mission. For this task, you will complete an autonomous mission for runway 28.
Create a Mission
Export a copy of your mission and upload a copy to Brightspace.
Fly the mission
Task 3 - Stabilized Circuit
Stabilized flight is the primary outcome of this course. This section is extremely important to practice and perfect.
Capture a screen recording of your stabilized circuit, and upload a copy to Brightspace.
