Selig sim 1

Open the

flight manual⁠

for the aircraft and record the following:

What does the right stick control?

Ailerons and elevator

What does the left stick control?

Rudder and Throttle

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? The right stick is used going left or right.

Explain how the ailerons move to make the aircraft maneuver. The ailerons move on the wing to allow it to roll.

Check elevator:

Which stick and motion is used? The right stick is used going up and down.

Explain how the elevator moves to make the aircraft maneuver. The horizontal tail flaps move allowing the nose to point up or down.

Check rudder:

Which stick and motion is used? The left stick is used going left or right.

What else is controlled with the rudder input? The throttle.

About what axis does the rudder control the aircraft? The horizontal 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)?

20 mph

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

70%

Zero Wind Taxi

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 become inverted.

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.

Pushing the left stick to the right.

The aircraft is facing you and taxing to the east.

Pushing the left stick to the left now

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

Crosswind Taxi

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 zero wind you don’t need your rudder to help keep the aircraft straight.

Why is the rudder input different?

The rudder input is different because the wind is forcing the pilot to use it to correct the direction.

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)⁠

You can also use the ailerons.

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

Headwind Taxi

What wind speed and direction did you choose?

I chose 6mph south wind speed and direction

What did you notice about the throttle input?

The throttle has to be higher

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

Zero Wind Taxi⁠

? If not, what happened?

No because the wind is slowing the plane down.

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