PAR	string	Precision Approach Radar Precision Approach Radar (PAR) is designed for use as a landing aid rather than an aid for sequencing and spacing aircraft to provide lateral and vertical guidance to an aircraft pilot for landing up to the missed approach point. PAR equipment may be used as a primary landing aid or it may be used to monitor other types of approaches. It is designed to display range, azimuth, and elevation information. It is similar to an instrument landing system (ILS) but requires control instructions. One type of instrument approach that can make use of PAR is the ground-controlled approach (GCA).
ARSR	string	Air Route Surveillance Radar Air Route Surveillance Radar (ARSR) or Route Surveillance Radar (RSR) is a system of remotely located, long-range radars that primarily provides a display of aircraft locations over large areas to air route traffic control centres

The ASR can also be used as an instrument approach aid.
SSR	string	Secondary Surveillance Radar or ATCRBS (Air Traffic Control Radar Beacon System) Secondary Surveillance Radar (SSR) (aka Secondary Radar (SECRA) or ATC Radar Beacon System (ATCRBS)) is a radar system in which the object to be detected is fitted with the cooperative equipment in the form of a radio receiver/transmitter (transponder). Radar pulses transmitted from the searching transmitter/receiver (interrogator) site are received in the cooperative equipment and used to trigger a distinctive transmission from the transponder. This reply transmission, rather than a reflected signal, is then received back at the transmitter/receiver site for processing and display at an air traffic control facility.

MODE_2	string	Mode 2 provides 4-digit octal unit code. (military only - set on ground for fighters, can be changed in flight by transport aircraft)
MODE_3A	string	Mode 3/A provides a 4-digit octal identification code for the aircraft, assigned by the air traffic controller. (military and civilian)
MODE_4	string	Mode 4 provides a 3-pulse reply to crypto coded challenge. (military only)
MODE_5	string	Mode 5 provides a cryptographically secured version of Mode S and ADS-B GPS position. (military only)
MODE_C	string	Mode C provides 4-digit octal code for aircraft's pressure altitude. (military and civilian)
MODE_S	string	Mode S provides multiple information formats to a selective interrogation. Each aircraft is assigned a fixed 24-bit address. (military and civilian) Mode S, or mode select, despite also being called a transponder radar system replacement for Air Traffic Control Radar Beacon System (ATCRBS), is actually a data packet protocol which can be used to augment ATCRBS transponder positioning equipment (radar and TCAS). Mode S is designed to fully interface with ATCRBS systems: mode S SSRs can interrogate ATCRBS transponders, and AIS-P transponders will also reply to older ATCRBS and TCAS interrogations.

MASONRY	string	Building materials (for example: stone, brick, concrete, hollow-tile, concrete block, gypsum block, or other similar building units or materials and/or combination of the same) bonded together with mortar to form a structure (for example: a wall, a pier).
METAL	string	Any of the class of substances that are characteristically lustrous, ductile, fusible, malleable solids and are good conductors of heat and electricity. For example, gold, silver, copper, iron, lead, tin, and certain alloys (as brass and bronze).
MUD	string	Constructed principally from mud applied to a structural scaffold of plant material (for example: wooden posts). Effective only in extremely dry climates and usually must be resurfaced on a regular basis (for example: yearly) otherwise the structure steadily disintegrates under the effect of weather.
PLANT	string	Plant material (for example: straw and/or tall coarse grass), possibly also containing the slices of soil to which the plant material is attached. For example, used in thatching or sodding a roof.
PRESTRESSED_CONCRETE	string	Reinforced concrete in which internal stresses have been introduced to reduce potential tensile stress in the concrete resulting from loads.
REINFORCED_CONCRETE	string	Poured concrete containing steel bars or metal netting to increase its tensile strength.
SOD	string	A usually square or oblong piece or slice of earth together with the grass growing on it.
STEEL	string	Any of numerous artificially produced alloys of iron containing up to 3 per cent of other elements (including less than about 2.2 per cent carbon) and having great strength and malleability. Able to be tempered to many different degrees of hardness. Used for making tools, weapons, and/or machinery.
STONE	string	Pieces of rock or mineral substance (other than metal) of definite form and size, usually artificially shaped, and used for some special purpose. Used, for example, for building, for paving, or in the form of a block, slab, or pillar set up as a memorial and/or a boundary-mark.
TREATED_TIMBER	string	A timber that has been impregnated with chemicals (for example: creosote oil) to reduce damage from wood rot and/or insects. Often used for the portions of a structure that are likely to be in ongoing contact with soil and/or water.
WOOD	string	The hard, compact, fibrous substance of which the roots, trunks, and branches of trees and shrubs consist. Consists largely of secondary xylem, which forms the strengthening and water-transporting tissue of the plant.

SDF (extends: NavaidEquipment)
<<feature>>	[Logical View::AIXM::AIXM Features::Navaids Points::Navaids]
Definition
Simplified Directional Facility (SDF) provides a final approach course similar to that of the ILS localizer although is not as precise as Localizer. It does not provide glide slope information. The SDF transmits signals within the range of 108.10 to 111.95 MHz. The approach techniques and procedures used in an SDF instrument approach are essentially the same as those employed in executing a standard localizer approach except the SDF course may not be aligned with the runway and the course may be wider, resulting in less precision. Usable off-course indications are limited to 35 degrees either side of the course centreline. Instrument indications received beyond 35 degrees should be disregarded. This angle is generally not more than 3 degrees. The SDF signal is fixed at either 6 degrees or 12 degrees as necessary to provide maximum flyability and optimum course quality.

SecondarySurveillanceRadar (extends: SurveillanceRadar)
<<feature>>	[Logical View::AIXM::AIXM Features::Surveillance]
Definition
Secondary Surveillance Radar (SSR aka Secondary Radar (SECRA)) is a radar system in which the object to be detected is fitted with the cooperative equipment in the form of a radio receiver/transmitter (transponder). Radar pulses transmitted from the searching transmitter/receiver (interrogator) site are received in the cooperative equipment and used to trigger a distinctive transmission from the transponder. This reply transmission, rather than a reflected signal, is then received back at the transmitter/receiver site for processing and display at an air traffic control facility.
Properties
transponder	CodeTransponderType	Mode S, or mode select, despite also being called a transponder radar system replacement for Air Traffic Control Radar Beacon System (ATCRBS), is actually a data packet protocol which can be used to augment ATCRBS transponder positioning equipment (radar and TCAS). Mode S is designed to fully interface with ATCRBS systems: mode S SSRs can interrogate ATCRBS transponders, and AIS-P transponders will also reply to older ATCRBS and TCAS interrogations.
autonomous	CodeYesNoType	Indicates the SRR is autonomous or independent.
monopulse	CodeYesNoType	Monopulse radar is an adaptation of conical scanning radar which sends additional information in the radar signal in order to avoid problems caused by rapid changes in signal strength. The system also makes jamming more difficult. Most radars designed since the 1960s are monopulse systems.
