C-17 aircraft
strapdown system; utilizes ring laser gyros; dual digital interface (2 remote terminals) ; one interfaces with mission bus; one interfaces with efcs bus; BUILT-In battery charger; 28 vdc from aircraft power; 28 vdc from battery; rack mounted; electrostatic discharge sensative
the inertial reference unit utilizes a set of accelerometers and ring laser gyros to sense aircraft rates and accelerations, computes and provides aircraft attitude, attitude rates, true heading, velocity, acceleration and position information to the C-17 mission computer for navigation and display purposes; attitude rates, heading, ground speed, flight path angle, inertial angle of attack (aoa) , aoa rate, side slip angle and side slip angle rate
An electromechanical and/or electronic device, consisting of sensors, accelerometers, gyroscopes for the pitch, roll and yaw axis, and a processor, to provide velocity and angular position data. May be a component of an inertial navigation unit.
Packaging is in accordance with a procedural specification or a special packaging instruction (spi). the appropriate specification number will be shown in the clear in the supplemental data area.
Special requirements.
OPI: Optional Procedure Indicator Code. A one position alpha code that indicates the allowable deviations from the prescribed requirements.
SPI No.: Special packaging instructions number.
LVL A/B/C: Indicates the type of shipping container required for level A, B, or C maximum packing protection.
SPC Mkg: A two position code that identifies the special markings applied to the container, which is part of the total pack to protect the contained item during preservation, packing, storage, transit and removal from the pack.
Indicates there is no information in the hmirs. The nsn is in a fsc in table ii of fed std 313 and a msds may be required by the user. The requirement for a msds is dependent on a hazard determination of the supplier or the intended end use of item.
Item does not contain precious metal.
Represents items with esd sensitivity.
Represents items with no adp components
The item does not have a nuclear hardened feature or any other critical feature such as tolerance, fit restriction or application.
HMIC: Hazardous Material Indicator Code. A one position code that identifies a hazardous item.
PMIC: Precious Metal Indicator Code. A one position code which identifies items that have precious metals as part of their content. precious metals are those metals generally considered to be uncommon, highly valuable, and relatively superior in certain properties such as resistance to corrosion and electrical conductivity.
ESD: Electrostatic Discharge. Indicates if an item is susceptible to electrostatic discharge or electromagnetic interference damage. electrostatic discharge damage occurs when an accumulation of static electricity generated by the relative motion or separation of materials is released to another item by direct contact. electromagnetic interference damage occurs when an item comes into proximity with an electrostatic or magnetic field.
ENAC: Enviromental Attribute Code. Identifies items with environmentally preferred characteristics.
CRITL: Criticality Indicator Code. Indicates an item is technically critical by tolerance, fit, application, nuclear hardness properties, or other characteristics.
