Pavement markings aid in the movement of aircraft along airport surfaces and identify closed or hazardous
areas on the airport. The precision markings on Runway 26R identify the runway center line, designation; touch down point, threshold, aircraft holding positions, and pavement edge. The non precision markings on Runway 3-21 and Runway 8R-26L identify the runway centerline, threshold, designation, and aircraft holding positions. Runway 8L is equipped with basic markings, which identify the runway center line, designation, and aircraft holding positions. Taxiway and apron center line markings are provided to assist aircraft using these airport surfaces. Taxiway centerline markings assist pilots in maintaining proper clearance from pavement edges and objects near the taxiway/taxilane edges.
The airport is equipped with an automated surface observation system (ASOS). An ASOS is a suite of sensors, which measure, collect, and disseminate weather data. The sensors measure weather parameters such as wind speed and direct ion, temperature and dew point, visibility, cloud heights and types, precipitation, and barometric pressure. Chino Airport is also equipped with seven lighted wind cones which provide pilots with information about wind conditions. INSTRUMENT APPROACH PROCEDURES Instrument approach procedures are a series of predetermined maneuvers established by the FAA using electronic navigational aids that assist pilots in locating and landing at an airport during low visibility and cloud ceiling conditions. There are two published instrument approaches to Chino Airport: an Instrument Landing System (ILS) approach to Runway 26R and a VOR/GPS-B circling approach. The Runway 26R ILS approach is a precision instrument approach which provides both vertical descent information and course guidance information to the pilot. In contrast, the VOR/GPS-B circling approach is a nonprecision approach, providing only course guidance information to the pilot. The capability of an instrument is defined by the visibility and cloud ceiling minimums associated with the approach. Visibility minimums define the horizontal distance that the pilot must be able to see in order to complete the approach. Cloud ceilings define the lowest level a cloud layer (defined in feet above the ground) can be situated for the pilot to complete the approach. If the observed visibility or cloud ceilings are below the minimums prescribed for the approach, the pilot cannot complete the instrument approach.
LOCAL OPERATING PROCEDURES
Chino Airport is situated at 652 feet MSL. The traffic pattern altitude for all aircraft at the airport is 750 feet above the airfield elevation (1,402 feet MSL). Aircraft landing Runways 3, 8L, and 8R follow a right-hand traffic pattern. In this manner, aircraft approach the desired runway end following a series of right-hand turns. A left-hand traffic pattern has been established for Runways 21, 26L, and 26R. By providing for these “nonstandard” traffic patterns, aircraft traffic operating on the parallel runway system is maintained south of Merrill Avenue. Aircraft operating on Runway 3-21 remain southeast of the airport. These patterns ensure that aircraft operating at Chino Airport do not enter the inner ring of the Class C airspace for Ontario Inter national Airport. A voluntary noise abatement program at the airport requests that pilots avoid noise sensitive areas to the west and southwest. AIR TRAFFIC CONTROL The Chino Airport ATCT controls aircraft operating within Class D airspace that surrounds Chino Airport and on the airfield operational areas. The Chino ATCT is located north of Runway 8L-26R, east of Taxiway B. The FAA operates the Chino ATCT daily from 7:00 a.m. t o 9:00 p.m. All aircraft operating within the Class C airspace for Ontario International Airport are controlled by SOCAL approach control. SOCAL approach control is responsible for much of the airspace in the Los Angeles area and provides participating pilots with altitude, aircraft separation, and route guidance information. Enroute air traffic control services are provided through the Los Angeles Air Route Traffic Control Center (ARTCC).
