Jul 13, 2024 · The ADIRU, the heart of the Air Data Inertial Reference System, has two distinct partitions with independent processors. The air data function calculates critical air data such as airspeed, Mach, angle of attack, air temperature and barometric altitude.

The ADIRU consists of a Power Supply, an Air Data Module and the Inertial Reference Unit which performs air, and inertia related calculations. Operating power for the L ADIRU comes from the 115/28 VAC standby bus where the R ADIRU from 115VAC/28VAC XFR bus 2.

ADIRS maintenance codes show on the IRS DISPLAY of the ISDU. Some codes give the condition of ADIRS components and signals. Some codes give instructions. Two or more codes cause the ISDU CLR key light to come on. Push the CLR key to show the codes in sequence. The ADIRS maintenance codes come from the ADIRUs.

Nov 1, 2017 · What is the main difference and advantage in the Air Data System, between the former architecture (ADS + INS) and the newer one (ADIRS/ADIRU)? The primary difference is packaging, which saves space and weight. The ARINC 704A IRU is a 4 MCU size LRU. Likewise, the ARINC 706 ADC is also a 4 MCU unit.

Feb 15, 2013 · The document discusses the Air Data Inertial Reference System (ADIRS) on the Boeing 737 NG. The ADIRS contains two air data inertial reference units (ADIRUs) that each have an air data computer and inertial reference system.

Dec 16, 2024 · Boeing 737 ATA Chapter 21 covers the air conditioning, pressurization, and ventilation systems of the airplane. The Boeing 737 air conditioning system provides temperature-controlled air by processing bleed air from the engines, APU, or a ground air source in air conditioning packs.

The purpose of this video is to demonstrate how to align the Honeywell ADIRU on a Boeing 737NG aircraft.

Jul 30, 2023 · The Air Data Inertial Reference System (ADIRS) is a vital component of the Boeing 737 aircraft. It plays a crucial role in providing accurate and reliable aircraft navigation, control, and performance information.
