With this comes the need to keep things organized to reduce Foreign Object Debris (FOD) and confusion in flight. CFI Notebook | PDF | Risk Management | Flight Instructor - Scribd The 13 Colonies (an odd number) were on the east coast of the U.S. NEODD SWEVEN: North East Odd, South West Even, Once a route has been chosen, you need to calculate headings/courses to be flown. Additional data elements will be added in subsequent releases to include: departure procedures, standard terminal procedures. Motivator: Cockpit management are the actions and procedures, starting with preflight, in which all necessary equipment, documents, checklists, and navigation charts appropriate for the flight are on board and easily accessible. However, selecting and inserting individual, named fixes from the database is permitted, provided all fixes along the published route to be flown are inserted. [Figure 1-5], Intersections along the airway route are established by a variety of NAVAIDs, NDBs, localizers, and off-route VORs are used to establish intersections, NDBs are sometimes collocated with intersections, in which case passage of the NDB would mark the intersection, A bearing to an off-route NDB also can provide intersection identification, A localizer course used to identify an intersection is depicted by a feathered arrowhead symbol on the en route chart (, If feathered markings appear on the left-hand side of the arrowhead (, On AeroNav Products en route charts, the localizer symbol is only depicted to identify an intersection, Off-route VORs remain the most common means of identifying intersections when traveling on an airway, Another means of identifying an intersection is with the use of DME, If the DME mileage at the intersection is a cumulative distance of route segments, the mileage is totaled and indicated by a D-shaped symbol with a mileage number inside, [Figure 1-4] Approved IFR global positioning system (GPS) units can also be used to report intersections, DME and GPS provide valuable route information concerning such factors as mileage, position, and ground speed, Even without this equipment, information is provided on the charts for making the necessary calculations using time and distance, The en route chart depicts point-to-point distances on the airway system, Distances from VOR to VOR are charted with a number inside of a box, To differentiate distances when two airways coincide, the word "TO" with the three-letter VOR identifier appear to the left of the distance boxes, VOR changeover points (COPs) are depicted on the charts by this symbol, The numbers indicate the distance at which to change the VOR frequency, The frequency change might be required due to signal reception or conflicting frequencies, If a COP does not appear on an airway, the frequency should be changed midway between the facilities, A COP at an intersection may indicate a course change, Occasionally an "x" appears at a separated segment of an airway that is not an intersection, The "x" is a mileage breakdown or computer navigation fix and may indicate a course change, Today's computerized system of ATC has greatly reduced the need for holding en route, However, published holding patterns are still found on charts at junctures where ATC has deemed it necessary to enable traffic flow, When a holding pattern is charted, the controller may provide the holding direction and the statement "as published. ), Advanced RNP is a NavSpec with a minimum set of mandatory functions enabled in the aircraft's avionics suite. In general, these types of unintentional interference are localized and intermittent. Supporting structures such as guy wires exist here as well, Some locations identify these obstructions with unique sequencing flashing white strobe light systems, However, many power lines do not require notice to the FAA and, therefore, are not marked and/or lighted, Many of those that do require notice do not exceed 200 feet AGL or meet the Obstruction Standard of 14 CFR Part 77 and, therefore, are not marked and/or lighted, Pilots are cautioned to remain extremely vigilant, especially in the case of seaplane and/or float-equipped aircraft, The majority of unmanned free balloons currently being operated have, extending below them, either a suspension device to which the payload or instrument package is attached or a trailing wire antenna, or both, Good judgment on the part of the pilot dictates that aircraft should remain well clear of all unmanned free balloons and flight below them should be avoided at all times, Pilots are urged to report any unmanned free balloons sighted to the nearest FAA ground facility with which communication is established to assist FAA ATC facilities in identifying and flight following unmanned free balloons operating in the airspace.
