Overview

Tasks

Simulator Setup

Aircraft Selection

In SeligSIM, select Single Pilot > Freestyle.

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).

⁠

Open the

flight manual⁠

for the aircraft and record the following:

What does the right stick control?

Controls the elevator and ailerons

What does the left stick control?

Controls the throttle which is the speed controller and the rudder

Transmitter Settings

Broken link⁠

, 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.

Environmental Settings

Flying Site: Frasca Airport

Sun/Sky: Whiskey Uniform

Wind: Steady Winds: 0 mph at startup

Flight View Settings

Enter the simulator by clicking the “Fly” button and the aircraft will appear situated on the runway.

Review the

Widgets and Tools section⁠

of the user manual and set the following to replicate the screenshot below. These must be in the view of your screen recording.

Enable transmitter view

Enable HUD

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 moving left and right

Explain how the ailerons move to make the aircraft maneuver.

The ailerons move opposite of each other and are on the longitudinal axis. Ailerons are used to turn the aircraft left or right.

Check elevator:

Which stick and motion is used?

The right sticking moving up and down uses the elevator

Explain how the elevator moves to make the aircraft maneuver.

in flight, the elevator moves up and down using the right stick so the plane pitches up and down and is used to pitch the aircraft in a turn.

Check rudder:

Which stick and motion is used?

The left stick moving left and right horizontally.

What else is controlled with the rudder input?

The front gear is also connected with the rudder

About what axis does the rudder control the aircraft?

The vertical or yaw axis

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)?

37 mph at zero wind conditions

At approximately what throttle percentage does the aircraft takeoff in zero wind conditions?

At approximatley half throttle 50% where the plane can takeoff in zero wind conditions

Zero Wind Taxi

The wind setting should be already be set from

Environmental Settings⁠

to 0 mph.

Taxi Training

⁠

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

⁠

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)?

The inputs changed since the farther away the aircraft is from my orientation, the less accuracy my control inputs are.

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.

Based on orientation, i would turn use left rudder to turn north. If i used right rudder, the plane would turn south.

The aircraft is facing you and taxing to the east.

I would apply right rudder to turn the aircraft north and use the left rudder to turn south.

Once you are happy with your centerline disipline, record your screen and perform at least one out and back in both directions.

Crosswind Taxi

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.

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?

with the steady 6 mph south, it differs since it was tough to keep the plane on the centerline and i had to fully use left rudder to keep it on the runway and centerline. This differs from zero wind cause the faster i went, the hard it was to control cause of the crosswind.

Why is the rudder input different?

The rudder input was different because it required constant rudder inputs to the left to counter the wind.

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

starboard⁠

wing from lifting? Consider your total wind. You may refer to Chapter 2 of the

Airplane Flying Handbook (FAA-H-8083-3C)⁠

Another control i used was a decreased throttle which helped me point the aircraft back to the runway or the wind was pushing that plane to the grass. I used a little aileron to revent my starboard wing from tipping.

Once you are happy with your centerline disipline, record your screen and perform at least one out and back in both directions.

Headwind Taxi

Recording Required

⁠

Use the steps above to set a headwind and perform the taxi sequence then answer the questions below:

What wind speed and direction did you choose?

I chose to set the headwind at 8 mph East

What did you notice about the throttle input?

There was less throttle used in the 8mph headwind since there was airflow over the wings

Can you achieve the same perceived ground speed as you did in the

Zero Wind Taxi⁠

? If not, what happened?

No cause in the zero wind test throttle is much more, almost half in taxi speed, while the 8pmh headwind test gives only slight inputs in order to pretent tipping cause of the increased airflow.

Once you are happy with your centerline disipline, record your screen and perform at least one out and back in both directions.
