OXYGEN SYSTEM 

PX II

The oxygen system consists of a liquid system and an

emergency gaseous system.

LIQUID OXYGEN SYSTEM

A 5liter liquid oxygen system provides breathing

oxygen to a diluter demand oxygen regulator. The

regulator provides for selection of normal diluted

oxygen and 100 percent oxygen and selection of PBG.

Quickdisconnects are used to expedite egressing the

aircraft on the ground. Oxygen duration varies

depending upon altitude, regulator settings, and

usage.

Pressure Breathing for G (PBG)

The PBG mode of the oxygen regulator provides

pressure breathing above 4g's to enhance g tolerance

and reduce pilot fatigue. ECS air used to inflate the

gsuit is also used by the oxygen regulator to control

the amount of pressurization supplied to the oxygen

mask, helmet, and vest.

Oxygen System Controls and Indicators

Refer to figure 171 for description of the oxygen

system controls and indicators.

Oxygen Duration

Refer to figure 172.

EMERGENCY OXYGEN SYSTEM

The emergency oxygen system consists of a high

pressure bottle with a flow controller mounted on the

left side of the ejection seat. The hose is routed to the

right side of the seat. The system is activated:

D

Automatically upon ejection.

D

Manually by pulling the emergency oxygen green

ring located on the left aft side of the seat.

NOTES

:

1. Oxygen duration increases as cockpit pressure altitude increases because there is less ambient pressure

acting upon the lungs. Therefore, a smaller quantity of oxygen at altitude expands the lungs to the same

size that they were at sea level.

2. With two people, decrease NORM/100% oxygen duration by 50 percent.
3. Use of PBG may reduce the listed available oxygen times.

COMMUNICATIONS, NAVIGATION,

AND IFF (CNI) EQUIPMENT

Cockpit controls for CNI equipment are divided

between control units on the consoles and the upfront

controls located on the instrument panel. Controls for

less frequently used functions, such as power and

audio volume, and essential functions, such as

communications backup and guard, are located on

console panels. Controls for frequently used functions

of CNI are located on the upfront controls to permit

headup control during flight.

UPFRONT CONTROLS

Refer to figure 174. The upfront controls provide a

simplified, centralized, headup means of controlling

the most frequently used functions of the communica

tions system, navigation systems, and IFF. The

upfront control set consists of the data entry display

(DED), 

C

 

DF

 the integrated control panel (ICP), and

DR

 the integrated keyboard panel (IKP). The upfront

controls are powered by emergency dc bus No.2 and

emergency ac bus No. 2. Refer to F16D AIRCRAFT,

this section, for supplementary 

D

 information.

DED/CNI READOUTS

Refer to figure 174, 175, and 176. The DED is an

integral part of the upfront controls and provides a

visual display of the switch actions made via upfront

controls. The primary readouts of communication,

navigation, and IFF systems are included in the page

selections available for display on the DED. Channel,

frequency, mode, and code selections of UHF, VHF,

TACAN, ILS and IFF are presented when the

appropriate page is selected. Present position and

steerpoint data may be selected for display on the

DED.

Displays for UHF, TACAN, and IFF show the word

BACKUP when the 

PX II

 CNI, 

PX III

 C & I knob is in

BACKUP. The word GUARD appears on UHF and

VHF pages when guard is selected.
