A

Detailed

Explanation

1.

Establish

trimmed

level

flight

on

a

fixed

heading

You

should

start

the

procedure

by

placing

the

aircraft

in

level

flight,

in

neutral

trim,

on

a

fixed

heading.

Try

to

maintain

a

constant

altitude

during

the

procedure.

2.

Engage

the

Autopilot

(AP)

in

TRK+ALT

mod

To

engage

the

autopilot

in

TRK+ALT

mode:

1.

Enter

the

AP

Menu

(MAIN

MENU

>

AP)

2.

Press

button

3,

TRK+ALT

3.

It

should

be

highlighted

and

look

like

Note

that

the

heading

(HDG)

bug

under

the

DG

changes

to

the

track

(TRK)

bug

in

track

mode.

3.

Allow

a

few

minutes

of

stable

flight

under

AP

control

Ensure

that

you

are

not

affecting

the

autopilot’s

control

of

the

roll

axis,

so

you

can

determine

the

autopilot’s

track

hold

and

turn

performance.

4.

Change

the

TRK

target

90

degrees

from

the

current

target

Change

the

heading

bug

to

90

degrees

to

the

left

or

right

of

current

heading.

1.

Configure

a

joystick

to

control

the

heading

bug.

The

label

above

the

joystick

should

read

(TRK)

2.

Turn

the

joystick

either

way

until

the

track

bug

reads

90

degrees

to

the

left

or

right

of

current

TRK

target

3.

The

aircraft

should

immediately

begin

turning

toward

the

new

TRK

target

5.

Check

for

ROLL

SLIP

indications

Observe

the

autopilot

status

indicator

on

the

Top

Bar

while

the

autopilot

flies.

If

the

banner

is

shown

frequently,

it

is

an

indication

that

the

roll

servo

is

slipping

and

the

servo

torque

needs

to

be

increased.

Occasional

slips

due

to

turbulence

are

acceptable.

If

frequent

ROLL

SLIPS

are

observed,

disconnect

the

autopilot

and

increase

ROLL

TORQUE

by

10%

(SETUP

MENU

>

AUTOPILOT

SETUP

>

ROLL

AXIS

>

TORQUE).

If

you

have

adjusted

the

roll

servo

torque

to

100%

and

are

still

seeing

frequent

slips,

you

may

need

to

try

a

higher

strength

servo

(e.g.,

if

you

have

an

SV32

installed,

try

swapping

for

an

SV42).

Contact

Dynon

for

assistance.

6.

Check

if

aircraft

is

slow

to

respond

Observe

the

speed

at

which

the

autopilot

responds

to

changes

in

TRK

setting.

If

the

autopilot

seems

too

slow

to

respond

or

“sluggish”,

disconnect

the

autopilot

and

increase

ROLL

SENSITIVITY

by

2

(SETUP

MENU

>

AUTOPILOT

SETUP

>

ROLL

AXIS

>

SENSITIVITY).
