For this exercise, select the Alpha 40, Scaled 60-size, 72-in Span (7-lb) aircraft. This is a trainer aircraft with forgiving controls and, importantly, tricycle gear (for taxi training).
, you connected and set up the Orqa FPV transmitter to work with your SeligSIM installation. You should not need to reattach this transmitter; however, it is recommended that you recalibrate, as you may not be using the same transmitter as before.
From the main menu in SeligSIM, open the transmitter selection window.
Select Calibrate and perform the calibration by following the on-screen prompts.

Controls Check
Recall from the SeligSIM training videos the importance of performing a control check prior to flying any aircraft. Check the controls and answer the questions inline.
After setting up the simulator above, flight “Fly” to enter the simulator.
Check ailerons:
Which stick and motion is used?
Right Stick, Left and right motions
Explain how the ailerons move to make the aircraft maneuver.
Help roll the aircraft to stay level and bank into turns.
Check elevator:
Which stick and motion is used?
Right Stick, Up and Down motions
Explain how the elevator moves to make the aircraft maneuver.
This controls the pitch of the aircraft and also helps it go through turns really smoothly.
Check rudder:
Which stick and motion is used?
Left Stick, Left and Right motions
What else is controlled with the rudder input?
Nose gear when taxiing
About what axis does the rudder control the aircraft?
Z-axis for yaw input
Check throttle:
The throttle should initially be pinned (held with your thumb) to 0%.
In real flight, we would complete additional checklist steps prior to a power check, but not for this exercise.
Announce that you will be starting the propellers by yelling (as appropriate) CLEAR PROP, then briefly apply a small percentage of throttle to verify that the propeller spins up. This will be a required step when launching the believers, so get comfortable with it early.
Aerodynamics Exploration
In this assignment, it is important that the aircraft does not fly since this is strictly ground manuevering. Using the simulator, test the following.
Methotically test the take off speed of the aircraft using ONLY the left slick (i.e. no elevator inputs) and answer the following:
At what speed does the aircraft takeoff in zero wind conditions (include units)?
26mph
At approximately what throttle percentage does the aircraft takeoff in zero wind conditions?
With the take off speed in mind, you will perform centerline control using only the rudder and throttle starting out at a very low speed working up to a fast taxi speed just below the takeoff speed. Use the video above as a reference (note that your video should include the HUD).
Recording Required
As a heads up, you will need to use the built in screen recorder (Snipping Tool) to record your full screen once you are happy with your centerline performance.
Use only the left stick to taxi the aircraft back and forth along the centerline towards the east and west. Gradually increase your speed while maintaining centerline disipline until you achieve a fast taxi similar to the video above.
As you complete this task answer the following:
How do your control inputs change as the aircraft reaches the edge of your vision limits (the few seconds before you turn around)?
They seem to be very choppy because of the fact it’s so far away and the depth perception is so off at that far away.
Describe your control inputs required to maintain centerline for the following scenarios using cardinal direction to describe the aircraft’s position. For example, if you are standing directly behind the aircraft that is heading north, left rudder moves the aircraft west, right rudder moves the aircraft east.
The aircraft is facing away from you and taxing to the east.
Left rudder moves the aircraft North, right rudder moves the aircraft south.
The aircraft is facing you and taxing to the east.
Left rudder moves the aircraft south, right rudder moves the aircraft North.
Once you are happy with your centerline disipline, record your screen and perform at least one out and back in both directions.
It’s considerable rare to fly in zero or runway aligned wind conditions, so it’s important to train for a crosswind and learn the control inputs to counter the forces.
Setting Wind
From the Main menu, open the Wind Selection menu and set the winds to Steady Winds: 6 mph from South according to the screenshow below.

Recording Required
As a heads up, you will need to use the built in screen recorder (Snipping Tool) to record your full screen once you are happy with your centerline performance.
Enter the flight simulator and perform the following scenarios and answer the corresponding questions.
Perform one out and back taxi using only the rudder
Use cardinal directions to describe one taxi scenario (i.e. taxing away from me toward the east) and the rudder inputs to maintain centerline. How does this differ from the zero wind scenario?
Taxing away from me towards the east the rudder inputs are definitely more right motion heavy into the wing.
Why is the rudder input different?
They are different because the plane is trying to counteract the wind loading that it didn’t have in the zero-wind speed scenario.
With the aircraft facing away from you and taxing to the east, answer the following:
In addition to the rudder, what other control (and direction) could you use to maintain stability and prevent the
