Flight

 

Test

 

Preparation

 

 

 

The

 

flight

 

test

 

should

 

be

 

conducted

 

on

 

a

 

clear,

 

VFR

 

day.

 

It

 

is

 

recommended

 

that

 

clearing

 

turns

 

be

 

performed

 

before

 

executing

 

each

 

procedure.

 

 

At

 

many

 

points,

 

the

 

pilot’s

 

attention

 

will

 

be

 

divided

 

between

 

documentation,

 

configuring

 

SkyView,

 

and

 

maintaining

 

situational

 

awareness.

 

Before

 

commencing

 

the

 

flight

 

test,

 

ensure

 

that

 

you

 

have

 

adequate

 

altitude,

 

clear

 

weather,

 

no

 

traffic,

 

no

 

obstructions

 

in

 

the

 

flight

 

path,

 

great

 

visibility,

 

no

 

airspace

 

conflicts,

 

etc.

 

If

 

possible,

 

bring

 

someone

 

along

 

on

 

the

 

first

 

autopilot

 

test

 

flight.

 

If

 

autopilot

 

behavior,

 

performance,

 

or

 

interference

 

with

 

the

 

controls

 

is

 

cause

 

for

 

concern

 

while

 

flying,

 

remember

 

that

 

the

 

autopilot

 

can

 

be

 

disconnected

 

in

 

any

 

of

 

the

 

following

 

ways

:

 

 

Press

 

the

 

Disconnect/CWS

 

button

 

 

If

 

using

 

the

 

SIMPLIFIED

 

controls:

 

o

 

Enter

 

the

 

AP

 

Menu

 

(MAIN

 

MENU

 

>

 

AP

 

MENU)

 

and

 

press

 

the

 

TRK+ALT

 

button

 

ƒ

 

 

indicates

 

the

 

autopilot

 

is

 

engaged

 

ƒ
