NOT FOR NAVIGATION A fly-over (FO) waypoint precludes any turn until the waypoint is overflown.  fly-by (FB) waypoint requires the use of turn anticipation to avoid overshooting the next segment.

There are specific requirements; however, that must be met  before using RNAV procedures. Every RNAV departure chart  lists general notes and may include specific equipment and  performance requirements, as well as the type of RNAV  departure procedure in the chart plan view. New aircraft  equipment suffix codes are used to denote capabilities for  advanced RNAV navigation for flight plan filing purposes.  [Figure 1-32]  operation. If not equipped with GPS, or for multi-sensor  systems with GPS that do not alert upon loss of GPS, aircraft  must be capable of navigation system updating using DME/  DME or DME/DME/ IRU for type 1 and 2 procedures. AC 90­ 100 may be used as operational guidance for RNAV ODPs.  Pilots of FMS-equipped aircraft who are assigned an RNAV  DP procedure and subsequently receive a change of runway,  transition, or procedure, must verify that the appropriate  changes are loaded and available for navigation. [Figures  1-29 and 1-30]  SID altitudes can be charted in four different ways. The  first are mandatory altitudes, the second, minimum  altitudes, the third, maximum altitudes and the fourth is a  combination of minimum and maximum altitudes or also  referred to as block altitudes. Below are examples of how  each will be shown on a SID chart.  Additionally, new waypoint symbols are used in conjunction  with RNAV charts. There are two types of waypoints  currently in use: fly-by (FB) and fly-over (FO). A FB waypoint  typically is used in a position at which a change in the course  of procedure occurs. Charts represent them with four- pointed stars. This type of waypoint is designed to allow  you to anticipate and begin your turn prior to reaching the  waypoint, thus providing smoother transitions. Conversely,  RNAV charts show a FO waypoint as a four-pointed star  enclosed in a circle. This type of waypoint is used to denote  a missed approach point, a missed approach holding  point, or other specific points in space that must be flown  •  Mandatory altitudes – 5500  •  Minimum altitudes – 2300  •  Maximum altitudes – 3300  1-36  SID Altitudes
