Unprogrammed extended facility shutdowns or other unanticipated outages that are expected to last more than 30 days shall be promptly reported to NFDC by administrative message or FAX. When possible, the expected duration of the shutdown is to be included in the message. Routine maintenance shutdown.
When possible, approval should be obtained sufficiently in advance of the proposed shutdown time to allow dissemination of a NOTAM at least 5 hours before a shutdown will occur. A routine maintenance shutdown request shall not be denied because of an inability to issue a NOTAM 5 hours in advance of the shutdown.
Emergency shutdown. When possible, at least 1-hour advance notice should be obtained so that appropriate dissemination may be made prior to shutdown. Extended maintenance shutdown. Notify the NFDC sufficiently in advance to permit publication of the information prior to the shutdown date. It does not refer to the automatic monitoring feature. One of the LLZ transmitters inoperative. LLZ far field monitor inoperative.

The Technical Operations service area office must concur with the site location before the request for study is made.
The establishment of instrument procedures. Designation of controlled airspace. The ability to provide essential air traffic services. The effect of the site on facility performance; and. The effect on the location or configuration of an airport.
If all offices agree with the selected site, then the service area office should circularize the proposal, as determined necessary, for comment from the aviation community. Convene an informal airspace meeting in accordance with the procedures detailed in chapter 2, section 6, of this Order. Informal airspace meetings may not be practical for time critical changes or in those cases where delay will adversely affect aviation safety.
At such meetings, agency representatives should explain the planned use of the NAVAIDs, including instrument approaches or other terminal procedures or airspace planning, and any action will be subsequently handled by airspace rulemaking procedures.
However, care should be taken that the agency's ex parte policy is not violated during these informal proceedings. The service area office is responsible for coordination and final approval or disapproval of sites selected for installation of en route NAVAIDs. The approval or disapproval determination shall be issued by memorandum to the appropriate Technical Operations service area office.
Any disapproval issued shall include the reasons why a site is not acceptable. Agency personnel are reminded that en route site approval does not constitute approval of instrument approach procedures or controlled airspace planning to be processed under rulemaking action.VOR Navigation Made Easy
The service area office shall distribute a copy of the approval or disapproval determination to all FAA offices that participated in the site study and to ARN As soon as possible thereafter, an estimated date of commissioning shall be agreed upon by the service area office, FPT, Technical Operations service area office, and any other concerned FAA offices. To the extent possible, the date of commissioning shall coincide with the associated aeronautical charting dates. The FPT shall process the necessary instrument procedures and the service area office shall process airspace rulemaking actions to be effective with the associated aeronautical charting date.

Distance miles. Power watts. Height feet above transmitter. Distance miles from transmitter. Altitude and distance limitations need not be applied when any of the following conditions are met:. Routing is initiated by ATC or requested by the pilot and the following is provided:.
NOTE- 1. Additionally, in accordance with paraApplication; such aircraft described herein may be provided nonradar separation, in lieu of radar separation, when an operational advantage will be gained. Operational necessity requires and approval has been obtained from the Frequency Management and Flight Inspection Offices to exceed them. Requested routing is via an MTR.
Use an altitude consistent with the limitations of the aid when clearing an aircraft to cross or hold at a fix. Request aircraft position reports only over fixes shown on charts used for the altitude being flown, except as follows:.
Unless the pilot requests otherwise, use only those fixes shown on high altitude en route charts, high altitude instrument approach procedures charts, and SID charts when clearing military turbojet single-piloted aircraft. An unpublished fix is defined as one approved and planned for publication which is not yet depicted on the charts or one which is used in accord with the following:. DME shall be used in lieu of off-route radials, whenever possible. Except where known signal coverage restrictions exist, an unpublished fix may be used for ATC purposes if its location does not exceed NAVAID altitude and distance limitation, and when off-route radials are used, the angle of divergence meets the criteria prescribed below.
NOTE- Unpublished fixes should not negate the normal use of published intersections. Frequent routine use of an unpublished fix would justify establishing a fix. Do not hold aircraft at unpublished fixes below the lowest assignable altitude dictated by terrain clearance for the appropriate holding pattern airspace area template regardless of the MEA for the route being flown.
When the unpublished fix is located on an off-route radial and the radial providing course guidance, it shall be used consistent with the following divergence angles:. Fixes contained in the route description of MTRs are considered filed fixes. Chapter 4. IFR Section 1. Routing is initiated by ATC or requested by the pilot and the following is provided: 1. Radar monitoring. When the unpublished fix is located on an off-route radial and the radial providing course guidance, it shall be used consistent with the following divergence angles: a When holding operations are involved with respect to subparas b and c below, the angle of divergence shall be at least 45 degrees.

Return to Table of Contents.When a facility is assigned responsibility for monitoring NAVAIDs, the air traffic manager shall issue monitoring instructions in a facility directive. Notification procedures shall be coordinated with the appropriate sector manager. Aurally check the identification at the beginning of each watch.
If a monitor Category 2 exists:. NOTE- 1. This monitor is usually connected to a remote alarm. If the standby transmitter does not work properly, the ATU will shut down the facility. Category 1: Alarm feature and identification heard at the control point.
Obstruction Evaluation / Airport Airspace Analysis (OE/AAA)
Category 2: Monitor equipment failure and identification not heard at the control point, but aircraft reports indicate that the facility is operating normally. TACAN joint-use airports :. Immediately notify the responsible military authority when an alarm is received. Consider the aid inoperative when the alarm cannot be silenced and the identification cannot be heard on the aural monitor. Check the identification at the beginning of each watch.
Monitor continuously by automatic means the beacons used as IFR aids. Check the operation at least once each hour if an automatic alarm is not available. Apply the procedures described in paraSystem Component Malfunctions, when there are indications that a component has failed. If you suspect that the indication is caused by a control line or a control station monitor failure rather than a malfunction of the component itself, take appropriate action as indicated in FAAO JO If a malfunction is confirmed, discontinue use of the component involved.
If the failure indication is caused by a control line or a control station monitor failure, the Technical Operations technician must advise if that component will be restored to operation and the monitor status. Monitor continuously by automatic means. If the provisions of subparas 1 or 2 above cannot be met, the compass locator may be considered monitored if it is equipped with an automatic monitor and shutdown feature at the site.
In this case responsibility for monitoring shall not be assigned to the air traffic facility. Take the following action when the alarm signal or a report indicates an air traffic system component malfunction:. Try to restore the aid to normal operation.
If unable to restore it, discontinue its use and:. FAAO Section 5. Navigational Aids It is any form of device that guides the pilot and his aircraft from one area to another. There are currently many different kinds of NAVAIDs in use today and their principal uses are to provide guidance, location, and direct ion. Navigational fix - A geographical position determined by reference to one or more radio navigational aids. ADF needle on frequency and pointed to marker.

Set and verify frequencies 3. Check for flags 4. Move with the marker to find primary heading. Write and use your pitch and power transition settings. By itself it is known as a VOR, and it provides magnetic bearing information to and from the station. The built-up static charge is usually slowly bled off into the atmosphereor as a quiet, non-luminous point discharge.
Once electronically relocated, they are referred to as waypoint s. The "J" in J42 stands for "Jet. Ei; FL for 35, ft. Generally, the broadcast contains routeoriented data with specially prepared NWS forecast s, inflight advisories, and winds aloft.

From Wikipedia, the free encyclopedia Jump to: navigation, searchFor other uses, see Statistics (disambiguation). This article needs additional citations for verification. Mathematical statistics is the application of mathematics to statistics, which was originally conceived as the science of the state the collection and analysis of facts about a country: its economy, land, military, population, and so on.
Mathematical techniques which are used for this include mathematical analysis, linear algebra, stochastic analysis, differential equations, and measure-theoretic probability theory. The initial analysis of the data from properly randomized studies often follows the study protocol.
The data from a randomized study can be analyzed to consider secondary hypotheses or to suggest new ideas. A secondary analysis of the data from a planned study uses tools from data analysis. While the tools of data analysis work best on data from randomized studies, they are also applied to other kinds of data --- for example, from natural experiments and observational studies, in which case the inference is dependent on the model chosen by the statistician, and so subjective.
More complex experiments, such as those involving stochastic processes defined in continuous time, may demand the use of more general probability measures. A probability distribution can either be univariate or multivariate. Important and commonly encountered univariate probability distributions include the binomial distribution, the hypergeometric distribution, and the normal distribution.
The multivariate normal distribution is a commonly encountered multivariate distribution. Statistical inference is the process of drawing conclusions from data that are subject to random variation, for example, observational errors or sampling variation. Inferential statistics are used to test hypotheses and make estimations using sample data. Whereas descriptive statistics describe a sample, inferential statistics infer predictions about a larger population that the sample represents.
The outcome of statistical inference may be an answer to the question "what should be done next. For the most part, statistical inference makes propositions about populations, using data drawn from the population of interest via some form of random sampling. More generally, data about a random process is obtained from its observed behavior during a finite period of time.
Given a parameter or hypothesis about which one wishes to make inference, statistical inference most often uses:In statistics, regression analysis is a statistical process for estimating the relationships among variables.
It includes many techniques for modeling and analyzing several variables, when the focus is on the relationship between a dependent variable and one or more independent variables.
More specifically, regression analysis helps one understand how the typical value of the dependent variable (or 'criterion variable') changes when any one of the independent variables is varied, while the other independent variables are held fixed.
Less commonly, the focus is on a quantile, or other location parameter of the conditional distribution of the dependent variable given the independent variables. Many techniques for carrying out regression analysis have been developed.
