Avtech is a leading manufacturer of

flight deck and passenger address

audio systems for the commercial,

regional and business jet market

sectors.

Avtech’s systems can be configured

to interface with most airframes,

requiring minimum design changes.

ARINC 429, 629 and Ethernet opti-

cal interfaces and spill-proof audio

panels are just some of the many

features available.

Avtech audio systems are onboard

the Boeing 787, 777, 767, 757,

737, 717; Embraer’s EMB 120, ERJ

135/145/170/ 190/195, Canadair’s

CRJ100, 200, 700, 900; DeHavilland’s

Dash 8-100, -200, -300, and the

CASA/IPTN CN-235 aircraft.

Audio Systems

Avtech’s Electronic GPS Clock is de-

signed to be a generic aircraft flight

deck clock and timing reference. This

highly accurate clock provides; Co-

ordinated Universal Time (UTC) and

date, Manual (MAN) time and date

and elapsed time.

A chronograph with sweep second

pointer and Elapsed Time is useful for

timing in holding patterns, procedure

turns, and approaches. This feature

can also be externally controlled.

In addition to providing a visual time

and date reference to the pilots,

the clock is capable of receiving

and transmitting the time and date

information over the aircraft’s ARINC

429 bus.

Avtech’s 9010 series clock has been

selected by Boeing as standard equip-

ment aboard B737 Next Generation

and B767-400 aircraft.

Chronometers

Avtech’s 7522 series of VHF Comm

Radio Tuning Panels are capable

of both 25 and 8.33 kHz channel

spacing. This cost-effective solu-

tion is in response to the European

requirement for 8.33 kHz VHF COMM

frequency spacing.

These panels offer a single base part

number that can tune both 500 and

700 ARINC series radios, providing

high reliability through the use of

electronic rather than mechanical

components. The Avtech approach

provides spares commonality,

improved maintainability logistics,

and an upgradable platform. Avtech

offers either a single or dual en-

coder configuration with or without

COMM Test and in three colors:

brown, black and gray. These units

have FAA TSO certification.

Radio Tuning

The SELCAL system consists of a

ground-based SELCAL encoder, a VHF

or HF communication system, and

the airborne decoder. Each aircraft’s

“SELCAL decoder” is assigned a

unique code. The airborne SELCAL

decoder is connected to the aircraft’s

VHF and HF radios. When the aircraft

is called, an aural alert is received and

the active radio is identified on the

cockpit annunciator panel, signaling

the flight crew to monitor the com-

pany radio frequency.

Avtech’s range of SELCAL products

includes ground-based desk-mounted

encoders; ramp testers with VHF and

HF (RF) outputs; standard ARINC 714

SELCALs; and space-saving, panel-

mounted SELCALs. Older aircraft also

benefit from Avtech’s legacy products

catering to the ARINC 531 standard.

SELCAL

A significant strength since Avtech’s

inception is the companies ability to

interface with aircraft sensors used

to monitor and control the aircraft

environment.

This strength is supported by Avtech’s

engineering expertise in system

design, signal processing, power

monitoring and control, and embed-

ded software design.

This ability has found its way into

many of Avtech’s innovative prod-

ucts such as windshield temperature

controllers, anti-Ice systems, voltage

and current monitoring, fluid level

monitoring, waste system monitor-

ing and control and switched mode

power supplies.

Control

Power Filtering

The Avtech active electronic filter

cancels up to a maximum of 8.0

Amps (rms) of current harmonics

on the 115 VAC, 400 Hz power line.

Primary applications are for IFE, LED

lighting, or military installations in

wide body aircraft when current har-

monics of newly added equipment

create potential AC bus problems. If

additional cancellation is required,

several filters can be operated in

parallel.

The filter mounts between the 115

VAC line and neutral and does not

require that the full bus current flow

through the unit. This product has

been Type Certified for the 747-400

and 767 and Avtech has received

Parts Manufacturing Approval (PMA)

from the FAA.

For over forty years, Avtech Corporation has been the industry leader in the design,

development, and manufacture of electronic systems for the aerospace industry.

Avtech products are flying onboard 42 aircraft types within air transport, regional

commuter, and military aircraft sectors, serving 450 customers in 49 countries world-

wide in vital aerospace and defense applications.
