Deviations in cockpit instrument readings will be taken into account during maneuver

evaluations.

NOTE

Once the clocks are slaved, do not reset them for any BI maneuvers.

REAR COCKPIT BAILOUT

Refer to T34C NATOPS. In the case of any actual emergency, immediately stow the

instrument hood.

NIGHT PREFLIGHT

Flight equipment as prescribed by NATOPS and local SOP will be worn or carried on all night

flights. Additionally, an operating flashlight and a clear visor will be included as part of the

required equipment. A preflight inspection will be conducted prior to each night flight in

accordance with NATOPS. A white lens flashlight will be used to conduct the preflight during

darkness. All exterior and cockpit lights will be checked during the preflight.

REAR COCKPIT LIGHTING

Refer to T34C NATOPS.

USE OF OXYGEN

Refer to T34C NATOPS for oxygen system description and use. Prior to every instrument

flight, a thorough preflight of the oxygen system and your mask will be conducted. Your

instructor will show you how to properly adjust the mask and connect the Inter Communication

System/Ultra High Frequency (ICS/UHF) radio cords. Since BI flights are conducted above

10,000 feet, improper use or a malfunction of the oxygen system could result in hypoxia or

hyperventilation.

Hypoxia

A reduction in the level of oxygen available to the body and its cells causes the physiological

condition of hypoxia. If the pilot is physically fit and there are no fumes in the cockpit, this

condition will probably never occur below 10,000 feet. Mechanically, it can be caused by a

leaking oxygen system, an inoperative mask, or a faulty regulator. Although no two individuals

are identical in objectively recognizable symptoms, the onset of hypoxia may be seen as a
