ATA 25-37 GALLEY INSERTS DESCRIPTION
DESCRIPTION The galley electrical system is comprised of a galley control module designed to provide electrical load to control the operation of the galley inserts. The galley control module is installed on the outboard side of the working face of the galley. It consists of circuit breakers to protect the circuitry of the galley inserts and switches to operate them.
The major components of the galley electrical system are the galley inserts. They are used by the flight attendants to provide the passengers with meals and beverages. The galley electrical inserts can include ovens and mini-ovens, coffee makers, water boilers, hot jugs and air chillers. The flight attendants control the galley inserts through the galley control module. COMPONENTS
OPERATION
HOT JUG
The electrical system can be operated when the galley is powered up. This is ensured when the circuit breakers are armed and all the inserts work correctly.
The hot jug has a capacity to hold 7.57 L (2 gal.) of liquid. It does not heat the liquid, it only maintains the temperature of the content. Before the flight, the hot jug must be removed from the galley and f illed with preheated beverage, then it is reinstalled in the galley to maintain the temperature of the beverage during the flight.
Abnormal operation of the galley electrical system consists of loss of power to any of the inserts due to wiring, electrical hardware or inserts internal fault. The tripping of the circuit breakers might be an indication of such failures. Also, any individual insert not operating can contribute to an abnormal operation.
COFFEE MAKER
The coffee maker is used by the flight attendants to serve freshly brewed coffee, as well as hot and cold water. It is mounted on a mounting rail that supports the electrical connector and the water supply coupling. The coffee maker is capable of brewing 1.6 L (0.42 gal.) of coffee in about 2 min and 45 s. The time delay between the end of one brew cycle and the start of the next is approximately 1 min. This coffee maker is available with an extended, manual faucet/tap. A heater plate, mounted on the base of the coffee maker, will maintain the brewed coffee above 77 °C (170 °F) for approximately 30 min.

ATA 25-60 EMERGENCY EQUIPMENT DESCRIPTION
LIFE RAFTS SYSTEM
This subsystem includes the equipment aimed at assisting the crew members and passengers in the event of an emergency condition.
The life raft system is designed to provide a safe and reliable flotation system for up to 36 persons in the event of ditching.
The emergency equipment comprises individual safety devices for the flight crew and passengers. These items of equipment are installed in a manner that they can be quickly accessed, without putting persons at risk or causing damage to the aircraft systems during in-flight emergency conditions. There are placards to indicate their locations.
In the cockpit, the emergency equipment comprises life vests for the crew members, located on the back of each pilot and copilot seat. Escape ropes are installed just above each direct-vision window. The escape ropes allow the evacuation of the cockpit crew through the window. A crash axe is also available.
EMERGENCY LOCATOR TRANSMITTER SYSTEM
In the passenger cabin, the emergency equipment comprises megaphones, crew and passenger life vests, seat belt extensions, a wheelchair, and a defibrillator.
The function of the ELT (Emergency Locator Transmitter) is to make the aircraft search and rescue operations easier, facilitating aircraft location. The ELT provides automatic transmission of the standard swept tone and encoded digital message sent to a satellite (COSPAS & SARSAT (Search and Rescue Satellite-Aided Tracking)) in the event of a crash. The emergency locator transmitter sub-subsystem transmits signals through emergency frequencies of 121.5 MHz, 243.0 MHz and 406.025 MHz. EMERGENCY-EVACUATION SLIDE SYSTEM
The emergency-evacuation slide system makes it possible for the passengers and crew members to safely leave the aircraft during an emergency evacuation.

ATA 25-60 Emergency Equipment
Embraer 190 Maintenance Training Manual ATA 25-61 EMERGENCY LOCATOR TRANSMITTER SYSTEM DESCRIPTION The ELT transmits the standard emergency swept tone on 121.5 and 243.0 MHz and the aircraft identification code or serial number of the transmitter, country code and the ID code on the 406.025 MHz. The 406.025 MHz transmitter transmits for 24 hours every 50 seconds for 520 ms and then is automatically shut down and has an average error of 1 to 2 km.
Upon power-up, the ELT/NAV interface unit reads the ELT's 24-bit address data and compares it to the 24-bit address data hardwired to the ELT/NAV interface unit. If there is a difference, the ELT/NAV interface unit reprograms the ELT according to the connector straps. If the two sets of data are identical, no action is taken.
The 121.5 MHz/243.0 MHz transmitter transmits continuously until the battery is drained which takes approximately 72 hours, and has an error of 15 to 20 km. The information sent to the satellite is programmed at the factory and contains a unique number that can be used to identify the beacon. ELT/NAV (Navigation) Interface Unit (new) When the ELT is coupled to an ELT/NAV interface unit, it also will transmit the position coordinates (longitude and latitude) of the aircraft in the encoded digital message, in the event of a crash. This results in a better accuracy of the position, which is approximately 100 m. The ELT/NAV interface unit will also be able to automatically reprogram the ELT with the aircraft 24-bit address in the event of an ELT replacement. One of the connectors of the ELT/NAV interface unit is wired, according to the aircraft 24-bit address.

The ELT buzzer is located next to the ELT unit, in the aft avionics compartment. It is fed by the ELT and therefore is not dependent upon the aircraft battery for operation. The ELT buzzer provides an aural sound to alert the pilot when the ELT has been activated and is transmitting. Its signal is loud enough to be heard outside the aircraft when the engines are off. It enables a search and rescue team to easily locate an aircraft with a transmitting ELT in a confined area with a large number of aircraft (i.e. such as an airport) so that they can disable the offending ELT without a great deal of effort.

The ELT/NAV interface unit is also installed next to the ELT unit, in the aft avionics compartment. The ELT/NAV interface unit gives to the ELT the capability of interfacing with the aircraft navigation system. It receives the position coordinates from the GPS (Global Positioning System) 1 receiver module through the generic I/O (Input/Output) module, both installed in the MAU (Modular Avionics Unit) 1, and send this information to the ELT. In the event of a crash, the ELT will transmit the position information from the navigation system. The crash site is instantly known due to the aircraft navigation system position data communication with the ELT via ELT/NAV interface unit. Without this interface, in the worst case, the time to locate the aircraft could take until 3 or 4 hours. In addition, the accuracy of the position fix is better than a system which does not use this interface (i.e. 100 m versus 1 or 2 km).

ATA 25-60 Emergency Equipment
Embraer 190 Maintenance Training Manual OPERATION The ELT signals transmitted on 121.5 and 243.0 MHz are modulated in AM. They are designated with the carrier amplitude modulated with an audio frequency sweeping downward over a range of not less than 700 Hz, within the range of 1600 to 300 Hz. The sweep repetition rate is between 2 and 4 Hz with a modulation factor of at least 0.85. The ELT signal transmitted in 406.025 MHz is a digital information message. The modulation is phase modulated and classified as 16K0G1D.Every 47.5 to 52.5 seconds the 5 W transmitter is turned on for 440 ms (short message) or 520 ms (short message). The transmitter has a G-Switch that senses the aircraft longitudinal deceleration. The G-Switch shall activate the ELT in accordance with the requirements as depicted in the response curve of the G-Switch. Two criteria govern the performance of the G-Switch sensor: •
•
A threshold force level (G th) below which the G-Switch sensor will not respond. A minimum velocity change (V min) before the G-Switch sensor will activate.
The ELT can be operated either manually or automatically. Under normal conditions, the ON/ARM switch of the ELT remote switch panel is in the ARM position and the ON/OFF switch of the ELT unit is in the OFF position. Upon impact (a change velocity of 4.5 +/- 0.5 ft/s or if subjected to 30 G’s of cross axis forces) the G-Switch will automatically activate, activating the ELT. The LED, in the ELT remote switch panel, will continuously flash and the swept tone will be audible.
performed within the first five minutes after the hour UTC (Universal Time Coordinated) and cannot exceed 30 seconds. After approximately 47 seconds the satellite system will consider the transmission as a valid distress signal. If the ELT is activated accidentally, it can be reset through the ON/ARM switch. The resetting is done when the switch is set to the ON position and then immediately set again to the ARM position. It is also possible to reset the ELT at the unit itself by positioning the ON/OFF switch on the ELT unit to ON position, then immediately back down to the OFF position. The ELT cannot be reset if either the ON/ARM switch of the ELT remote switch panel or the ON/OFF switch of the ELT unit is in the ON position. The DC ESS BUS 2 supplies power for the LED of the ELT remote switch panel. The status of the ELT, active or not active, is indicated on the ELT remote switch panel. When the ELT is active, a continuous flashing light will be present on the ELT remote switch panel. If a problem is detected, the light provides a coded signal following the initial 1-second pulse. The coded signal and related problems are as follows: •
1 flash indicates a G-Switch loop open failure.
•
3 flashes indicates a 406.025 MHz transmitter problem.
•
5 flashes indicates there is no navigation data present.
•
7 flashes indicates a battery problem.
For manual operation, the ON/OFF switch of the ELT unit or the ON/ARM switch of the ELT remote switch panel must be at the ON position. These switches can also be used to do the test of the ELT, which must be

ABNORMAL OPERATION
The emergency-evacuation slide system is armed or disarmed by moving the arm/disarm handle located on the door to the appropriate position. When the arm/disarm handle is moved to the armed position, the girt bar engages to the floor fittings. When the arm/disarm handle is moved to the unarmed position, the girt bar disengages from the floor fittings.
The emergency-evacuation slide system can operate in an abnormal mode as follows:
EMERGENCY EVACUATION CONDITION
•
With the emergency-evacuation slide system armed: •
•
•
•
•
•
The exit door pulls the primary release cable and pin when it is opened. This causes the slide pack to drop from the packboard. As the slide pack drops a preset distance, the firing cable pulls the firing pin from the regulator assembly to release the high pressure gas from the cylinder.
In case the inflation system does not actuate automatically, the flight attendant or another person has to pull the manual inflation handle. The manual inflation handle activates the inflation system and fully inflates the slide.
If the evacuation slide is damaged, punctured or torn, which makes it unable to hold air and inflate properly; it can be used as a non inflatable device, provided there is ground personnel assistance.
The high pressure gas flows through the hose assembly to the aspirator and inflates the slide. The pressure relief valve opens at a preset pressure to maintain the correct inflation pressure of the inflation tubes. When fully inflated, the slide is ready to be used for aircraft evacuation.

ATA 25-80 Insulation System
Embraer 190 Maintenance Training Manual COMPONENTS INSULATION SYSTEM
The aircraft has a thermal/acoustic insulation system that provides a thermally and acoustically controlled environment inside the cockpit and passenger cabin areas. The passenger and service doors are also provided with thermal and acoustic blankets. The insulation package consists of an insulation blanket constructed from flexible thermal/acoustic foam and fiberglass.
For other points, such as the access to the antenna, ice detector and TAT regions, there are special accesses on the insulation blankets to facilitate equipment maintenance.
The primary function of the thermal/acoustic insulation blankets is to stabilize the temperature, reduce the noise level and prevent a fire spread in the cockpit and passenger cabin in emergency situations. The insulation consists of thermal and acoustic blankets, constructed from multiple layers of lightweight fiberglass and foam enveloped in lowpermeability reinforced films. The insulation blankets are made up of individual packets fitted along the airframe. Each insulation blanket is identified with the part number, forward direction, location, frame bay and stringer location. There is a clearance between the dado panels, wiring, and hydraulic systems, to allow airflow and ensure integrity of the blankets. The insulation blankets are designed to provide a thermal and acoustic environment that gives an extra protection to the passengers and interior systems such as electrical cables, ducts and hoses. The insulation blanket was specially designed for optimum functionality. Each blanket has drain holes to maintain it dry and allow air pressure equalization in the blanket. In high-temperature areas such as loudspeakers, oxygen boxes, ballasts, batteries and lights, the blanket is provided with a high-temperature-resistant protective film. For the doors, the blankets are attached with velcro to allow easy maintenance and free operation of the door mechanism.

The aircraft has a sound dampener system that, together with the insulation and noise treatment felt, stabilizes the temperature and reduces the noise level in the cockpit and passenger cabin providing a thermally and acoustically controlled environment. The entrance and service doors are also provided with sound dampeners. The sound dampeners are fitted along the airframe, under the insulation and noise treatment felt. The sound dampeners are attached with adhesive to allow easy maintenance. NOSE TREATMENT FELT SYSTEM
The noise treatment felt system is installed along the fuselage of the aircraft to protect the passengers and flight attendants against the external noise of the aircraft. The passenger cabin is provided with a protective insulation layer installed underneath the sidewall panels and ceiling panels of the aircraft. The noise treatment felt system is not applicable to the cargo compartment and doors. SOFT BLUE SOUND DAMPENER SYSTEM
The soft blue sound dampener is installed on the ceiling of the aircraft to reduce the noise and vibration levels. The soft blue sound dampener is installed underneath the ceiling panels of centre fuselage I and centre fuselage III, between the insulation and the noise treatment felt. They are attached to the aircraft structure with the same tie-down straps that attach the noise treatment felts.
