Air Data

ADDU

The Air Data Display Unit (ADDU) is a self-sensing, RVSM compliant, digital air data computing (DADC) Altimeter with selectable altitude alerting. The ADDU inputs static (Ps) and pitot (Pt) pressures, total temperature (Tt), and installation configuration data (from an installation configuration module, model 9B-03508). Air data is output on ARINC 429 and RS422 data formats. […]

ADM

The IS&S Air Data Module (ADM), is a self-sensing, RVSM compliant, digital air data computer (DADC). The ADM inputs static (Ps) and pitot (Pt) pressures, total temperature (Tt), and installation configuration data (from an installation configuration module and discrete inputs). Air data is output on ARINC 429 and RS422 data formats. The ADM receives baro […]

ADS

Technical Overview The IS&S Model 9B-81103-1 Air Data Sensor (ADS) replaces the Rockwell Collins 590A- 3H/3J/3K/3J1/3K1 Air Data Sensor as either a form/fit/ function replacement unit, or as part of a more comprehensive Reduced Vertical Separation Minimum (RVSM) compatible air data system upgrade. This upgrade includes the IS&S Model 9D-80130 Air Data Display Unit (ADDU). […]

AIU

The Analog Interface Unit (AIU) is used in conjunction with the IS&S 9D-80130-1 Air Data Display Unit (ADDU), providing analog interface to the autopilot, navigation systems, and other using equipment. In application, air data is computed by ADDUs, then transmitted to a single AIU over isolated RS422 digital data links. The AIU converts the digital […]

Alerter

The IS&S Alerter provides two user selectable operating modes: Altitude Alerting, both audio and visual, to annunciate conditions of approach to and departure from a user selected altitude, and Minimum Descent Altitude (MDA) alerting to indicate approach to a minimum altitude. The indicator also provides display of Static Air Temperature (SAT) or Cabin Altitude as […]

Altimeter

The Altimeter is an RVSM compliant instrument capable of operating in self-sensing or repeater mode. In the Control configuration, it can operate in the self-sensing (Standby) or repeater (Normal) mode as selected by the operator. In the Monitor configuration, the Altimeter operates exclusively in the self-sensing mode, processing static pressure, barometric, and PSI correction factor […]

ICM

The Installation Configuration Module (ICM) is a component used with the IADDU and provides aircraft specific data to the IADDU, such as SSEC, Maximum Allowable Airspeed, Temperature Probe Type, Installation Configuration Display, LCD backlighting settings, analog output scale factor, and module software part number data. The exact subtype of the configuration module depends upon the […]

Mach Airspeed

The Mach Airspeed Indicator (MASI) is an RVSM compliant unit. In Standby mode, it processes pitot-static pressure, total air temperature, and altitude input data to compute and display calibrated airspeed (CAS), true airspeed (TAS), Mach number, and not-to-exceed airspeed (Vmo) data. In Normal mode, it displays CAS, TAS, ground speed (GS) Mach number, Vmo, and […]

SSBA

The IS&S Model Solid State Barometric Altimeter was developed under a joint Navy/Air Force contract as a plug-in replacement for the AAU-19/-34/-37 standard altimeters. IS&S’ advanced technology is twenty times more reliable and three times more accurate than existing designs. The SSBA combines a smooth mechanical pointer with a high intensity illuminated LCD display for […]
