The systems covered in this chapter are: • Oxygen system • Emergency exits • Locating devices • Miscellaneous emergency equipment This chapter deals only with factory-installed equipment. Individual aircraft may have other important emergency equipment installed. Refer to your Aircraft Operating Manual and Airplane Flight Manual supplements for the use of items installed at the Completion Center. Oxygen System Description An 1850-psi gaseous oxygen system is installed at the factory to supply oxygen to the flight crew and passengers during an emergency. The oxygen system consists of the following subsystems: • Flight compartment • Passenger compartment • Therapeutic • Portable oxygen bottle There are two different configurations of oxygen supply bottles installed on the Challenger 604. Although each configuration is unique, there is no difference in operation. Components and Operation Single-Bottle System The single-bottle system consists of one storage bottle, a ground servicing panel, and associated masks/regulators. The oxygen storage bottle (1260 liters/50.0 cubic feet) is located in the forward avionics bay. Dual-Bottle System The dual-bottle system consists of two storage bottles, a ground servicing panel, and associated masks/regulators. The flight compartment and passenger oxygen storage bottles (2603 liters/115 cubic feet per bottle) are located in the forward avionics bay. EMERGENCY EQUIPMENT 8-2 For Training Purposes Only Jan 04 P I LOT T R A I N I N G GU I D E Oxygen for the flight crew is provided through a diluter demand regulating system. A quick-donning, inflatable harness mask is installed in a container at each side console. Portable Oxygen Bottle A portable oxygen bottle is provided for the crew to use in moving around the cabin and is normally located in a placarded position behind the pilot. Passenger Compartment Dropdown masks installed above all of the passenger seats and in the lavatory provide passenger oxygen. The passenger masks are fixed-dilution (free-flow) type, which provides a mixture of oxygen and cabin air at ambient pressure. They are designed for use at cabin pressure altitudes below 25,000 feet. When the passenger oxygen system is active, the PAX OXY ON caution EICAS message is displayed. Therapeutic Provisions are made to install therapeutic oxygen ports in the passenger compartment. This system is used for first aid and normally supplies oxygen to four ports (forward left, aft left, forward right and aft right) at mid-height along the cabin. Controls and Indicators Overboard Discharge Indicator(s) If the oxygen storage bottle pressure becomes excessive, all oxygen will be vented overboard through a relief valve in the right forward fuselage. Single-Bottle System A green frangible disk located below and aft of the ground servicing panel will fragment to indicate the relief valve has activated due to an overpressure. The relief valve will activate when the HP module pressure exceeds approximately 2600 psi or when the LP module pressure exceeds 130 psi. Dual-Bottle System In dual-bottle systems, there are two green frangible disks located below and aft of the ground servicing panel to indicate that the relief valve has activated. One disk will rupture if the HP module pressure exceeds approximately 2800 psi. The other disk will rupture if the LP module pressure exceeds 90 psi. In all cases, an amber OXY LO PRESS message will be displayed on the EICAS when the oxygen pressure falls below 800 psi.

A quick-donning, inflatable-harness mask is installed in a container at each side console. Each container has a test lever, a yellow flow (eye) indicator, oxygen ON flag, a set of quick-release doors and connections for the oxygen and communications lines. Pressing the RESET/TEST switch can test oxygen flow through the regulator. The flow indicator (blinker) displays a yellow cross when oxygen is flowing. The flow indicator is black when there is no flow. When the mask is in use, a white ON flag comes into view on the left door of the container to indicate that the oxygen shutoff valve is open. When the mask is no longer required, closing the container doors and pressing the RESET/TEST switch stops the flow of oxygen to the mask and removes the white ON flag. The crew oxygen masks have controls located on the mask. The controls have the following selections: Normal /100% Lever • NORMAL – A diluted mixture of oxygen and ambient air adjusted for cabin altitude • 100% - Pure oxygen (100%) is delivered at a pressure dependent on cabin altitude Emergency Flow Control Knob • NORMAL (Unmarked) – Oxygen is regulated on demand • EMERGENCY – A constant flow of oxygen is delivered at a positive pressure • PRESS TO TEST (Momentary) – Purges the mask of smoke or noxious fumes Microphone Control Each mask has a microphone installed, which can be activated on the Audio Control Panel by selecting MASK/BOOM MIC switch to MASK. Inflatable Harness Control The flight deck masks are designed to be removed from their containers and donned with one hand. This is accomplished by squeezing the red tabs on either side of the oxygen line to inflate the harness while pulling the mask from the container. The inflated harness is placed over the head, and the mask is positioned over the nose and mouth. Releasing the red tabs deflates the harness, pulling the mask snugly against the face. EMERGENCY EQUIPMENT For Training Purposes Only May 03 8-5 P I LOT T R A I N I N G GU I D E The harness is not designed to be donned over headsets or eyeglasses. These should be removed prior to using the mask.

Main Entrance Door The main entrance door is classified as a Type I emergency exit and is the normal means of exit in an emergency. Overwing Emergency Exit The overwing emergency exit is a removable plug-type hatch and provides access to the right upper wing surface. It is classified as a Type III emergency exit. This emergency exit has an escape rope (lifeline) stored to the right of the exit window, with one end attached to the fuselage. Emergency Egress Lighting The Challenger 604 is equipped with an Emergency Egress Lighting System that operates for approximately 15 minutes from the time of activation. The Emergency Egress Lighting System location and operations are covered in Chapter 16 Lighting. EMERGENCY EQUIPMENT For Training Purposes Only May 03 8-9 P I LOT T R A I N I N G GU I D E Locating Devices Components and Operation Emergency Locator Transmitter (ELT) The ELT is located in the tail cone of the airplane and is activated automatically by G-forces in the event of a crash. The ELT transmits a signal on the international emergency frequencies of 121.5 and 243.0. A sealed battery pack is installed inside the ELT and provides at least 48 hours of operation. Underwater Locating Devices (ULDs) In addition to the ELT, there are Underwater Locating Devices (ULDs), which are part of the Flight Data Recorder (FDR) and the Cockpit Voice Recorder (CVR) systems. The ULDs automatically provide a locating signal should the airplane become submerged in water. Controls and Indicators The ON/ARM switch located on the ELT panel controls the emergency locator transmitter. With the ELT ON/ARM switch set to ARM, the automatic operating mode is selected and the ELT will activate when impact G forces are sufficient. The ON position permits ELT manual operation when desired. When the transmitter is in operation, the ON light on the ELT panel will illuminate.
