On procedures with both PBN elements and ground-based equipment requirements, the PBN requirements box will be listed first (See FIG 5-4-1. Pilots must not change any database waypoint type from a fly-by to fly-over, or vice versa. It is this concept that requires each NavSpec eligibility to be listed separately in the avionics documents or AFM.

Flight Management System (FMS): An FMS is an integrated suite of sensors, receivers, and computers, coupled with a navigation database These systems generally provide performance and RNAV guidance to displays and automatic flight control systems Inputs can be accepted from multiple sources such as GPS, DME, VOR, LOC and IRU It is not intended for every operator or aircraft. Pilots are encouraged to turn on their landing lights when operating within 10 miles of an airport (day or night) At the conclusion of night operations, reset all the switches for day, as such, check after the aircraft has flown at night to make sure the previous pilot did not forget.

That required capability will be listed in the PBN box. [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. cfi. An example of a generic NAVLOG is provided below: Fill out the departure and arrival airport information including frequencies, traffic altitudes, and heights above ground, Fill in information concerning flight service or any item you will want to reference in regards to that airport, If you want, draw an airport diagram in the box but still carry a larger printed diagram for easier use and more detail, Determine a MSL cruise altitude based on weather and direction of flight, Calculate pressure altitude for your airport (important for performance calculations), Determine the temperature (important for performance calculations), Calculate density altitude (important for performance calculations), Determine a horsepower setting and the accompanying RPM settings, KTAS and Gallons per Hour, Used to plot any changes to a heading for the entire route to estimate times, distances and fuel used, Fuel Planning calculated with flight computer (arrow on GPH, read under time), List all checkpoints and associated distances, Write in any frequencies or IDs for route navigation, GS (first or second line only): copy from preflight log, In flight you will be filling in the other boxes as the flight progresses, Weight and balance as calculated normally, Fill out any weather information or notes you may have, Fill out the flight plan for flight service, All information is from the front of the navigation log, Filed before flight with the FSS so they can keep a track of you. GPS is also a necessary component of the Aircraft Terrain Awareness and Warning System (TAWS) - an aircraft safety system that alerts pilots of upcoming terrain. In such airspace, the RNAV 10 NavSpec will be applied, so any aircraft eligible for RNP 10 will be deemed eligible for RNAV 10 operations. RNP AR DP is intended to provide specific benefits at specific locations. Airplane Flying Handbook, This is especially true when operating below 500' AGL and morseo below 200' AGL, Also, many of these structures do not meet charting requirements or may not yet be charted because of the charting cycle, Some structures do not require obstruction marking and/or lighting and some may not be marked and lighted even though the FAA recommended it, Notice to Air Missions (NOTAMs) will typically be published for any known unlit structures, but pilot vigilance is imperative in case the FAA has not yet been notified of outages, The glide distance of the airplane is based on the glide ratio, a performance number to provide an idea of the options available in an engine out, More than airports, suitable roads and fields options for emergency landings increases with increased altitude, Additionally, regulatory requirements, such as those found in FAR 91.205, specify supplemental survival equipment depending on glide-distance from shore if the flight is conducted for hire, Even further, FAR 91.509 further specifies supplemental survival equipment based on distance from shore, Winds are an important planning consideration both during terminal (surface winds) and cruise (winds aloft) environment, Surface winds are most commonly used for determining an optimal runway in the terminal area, Similarly, surface winds provide insight into optimal landing surfaces in an emergency along a route of flight, Wind direction and intensity at various cruise altitudes are an important consideration to determine cruise performance, Winds aloft are the most direct means to plan for winds at cruise altitudes along the route of flight, Headwinds increase flight time and therefore fuel burn, reducing range, while tailwinds do just the opposite, Further, headwinds require for power (increased fuel burn) and tailwinds decrease power requirements (decreased fuel burn), Except while holding in a holding pattern of 2 minutes or less (see.
