2.3 Parts

2.3.1 Included Parts

A. Model 4300-( ) Electric Attitude Indicator including Battery Pack (P/N 9015607).

B. Mating Connector, MS3116F8-4S or equivalent (P/N 9015514).

C. Installation Manual (P/N 9015762)

2.3.2 Installer Supplied Parts

A. Mounting Screw, 6-32UNC-2A. Three (3) required. (1” long screws are suggested for

panel thickness between 0.05 and 0.19, but may not be optimum in some installations.

The installer will need to determine what is correct for a particular installation.)

CAUTION:

Do not exceed 1.06” screw depth into bezel!

2.3.3 Additional Parts that may be required

A. Symbolic Airplane Adjustment Knob Cover Kit: (P/N 36022)

B. Slip Indicator Kit (P/N 36023)

C. Front Mount Kit: 3/32” thk (P/N 36028-1) or 1/2” thk (P/N 36027-1)

D. Panel Wedges: 3” (P/N PW3R-3) or 4” (P/N PW3R-4)

E. Remote Battery Mounting Kit (P/N 9015671)

2.4 Equipment

Location

The attitude indicator should be located within the aircraft in accordance with the following

considerations:

A. The indicator is ideally located in the instrument panel directly in line with the pilot's

normal line of sight. The "PULL TO CAGE" knob should be within easy reach.

Installations that result in viewing angles in excess of 30 degrees may reduce display

readability.

B. Compare the space requirements of the indicator with the installation area being

considered.

C. The power cable should not run adjacent to heaters, engine exhausts, or other heat

sources. Also, take care to route and tie the cable away from aircraft controls and

cables.

D. If remote mounting the standby battery, the cable length from the battery to the unit

should be kept as short as practical using wire of 22 AWG minimum. 18 AWG wire is

recommended for cable runs over 50 feet. Remote mounting the battery in a

location subject to extreme temperature variations may dramatically shorten the

emergency operation time available for the attitude indicator as well as the expected
battery lifetime (Fig 2.7 and 2.8). For optimum battery performance it is

recommended to mount the battery in a temperature controlled section of the

aircraft.
