X.br
X.\"-------------------------------------------
X.SH DESCRIPTION
X.LP
X\fBfplan\fP reads the \fIplanfile\fP consisting of departure and
Xdestination airports, navigation aids, intermediate checkpoints, fuel
Xconsumption rates, winds aloft, and produces a flight plan including
Xwind corrected heading, fuel consumption for each leg, vor fixes for
Xeach checkpoint, etc. \fBfplan\fP uses \fBnav(5)\fP format databases
Xfor upward compatibility with those widely distributed databases.
X.PP
XThe primary differences between \fBfplan\fP and \fBnav(1)\fP are that
X\fBfplan\fP will automatically compute VOR cross fixes (radial and
Xdistance to/from fix) at each waypoint along the flight and allow you
Xto enter a waypoint as ``15 miles since the previous waypoint along
Xthe current heading''. These features provide a kind of flight plan
Xmore useful in VFR / dead reckoning flight, where frequent checkpoints
Xare necessary. On Sun systems, a graphic preview of the flight can be
Xdisplayed in a scrollable window.
X.\"-------------------------------------------
X.SH OPTIONS
X.LP
X.TP 10
X.B \-l
XLookup the \fIdesignator(s)\fP in the databases and
Xprint their information to the standard output. If any designator
Xexists in both the airports and navigation aids databases, then both
Xentries are printed.
X.TP
X.B \-r
XProduce a return trip based on the input plan file. All waypoints are
Xreversed and incremental waypoints are recomputed. Correct \fBnav\fP
Xdirectives are included so that each waypoint uses the same VORs as in
Xthe input file. Fuel, wind, airspeed and altitude directives are not
Xincluded in the reversed plan.
X.TP
X.B \-g
X(Sun systems only). Preview the flight in a Sunview window. (NOTE: the
Xpreviewer uses a naive projection system - curvature of the earth is
Xignored. Do not use the preview map for navigation). The window is
Xdivided into two sections: the command panel and the map. The map is a
Xscrollable canvas where each waypoint and navaid is drawn. The command
Xpanel contains the following items:
X.br
X \fBQUIT\fP - Quits the previewer.
X.br
X \fBTO FIRST\fP - Scrolls the map to make the first waypoint visible.
X.br
X \fBTO LAST\fP - Scrolls the map to make the last waypoint visible.
X.br
X \fBBRIEF\fP - Toggles whether incremental waypoints are shown (similar
Xto the \fB-b\fP option).
X.br
X \fBSCALE\fP - Sets the scale of the map. The default scale is 100
Xpixels per degree of latitude.
X.TP
X.B \-
XRead the planfile from the standard input. If this option is present,
Xthen no \fIplanfile\fP may be specified.
X.TP
X.B \-d
XAppend a sorted summary of all database objects used in the planfile.
X.TP
X.B \-e
XUse Epson (IBM/PC) style box characters on the output form instead of the
Xdefault `+', `-', and `|'. Produces a more readable form if your terminal
Xand/or printer is capable of printing IBM box characters.
X.TP
X.B \-n
XSelect the narrow output format (no VOR cross fixes). Fits on a 80
Xcharacter terminal. Mutually exclusive with the \fB\-w\fP option
X[DEFAULT].
X.TP
X.B \-w
XSelect the wide output format (with VOR cross fixes). Can be up to 136
Xcharacters wide (depending on the number of active VORs). Mutually
Xexclusive with the \fB\-n\fP option.
X.TP
X.B \-s
XSelect statute miles (and miles per hour) for output form. Default is
Xnautical miles (and knots). Note: All speeds and distances in the
X\fIplanfile\fP are assumed to be knots and nautical miles unless
Xexplicitly marked by the \fBmi\fP or \fBmph\fP keywords.
X.TP
X.B \-b
XSelects \fIbrief\fP mode. Intermediate waypoints (those which are not
Xturning points) are not included in the output form. Useful for seeing
Xthe 'big picture'.
X.TP
X.B \-t
XDisables automatically tracking navaids in the primary navigation
Xradio (nav(1)). By default the nav(1) VOR automatically tracks to the
Xnext navaid (or from the previous one). When this option is enabled
X[DEFAULT], user specified nav(1) assignments are overridden.
X.\"-------------------------------------------
X.SH "PLANFILE FORMAT"
X\fBfplan\fP accepts a reasonably free-format input language to specify
Xdeparture and destination airports, winds aloft, intermediate
Xwaypoints, etc. The \fIplanfile\fP consists of any number of
Xsemicolon (;) separated descriptors. Comments are introduced by a
Xhash mark (#) in any column (all characters following the # on the
Xline are ignored). Each boldfaced keyword is case sensative - all are
Xlowercase. A \fIdesignator\fP, on the other hand, is not case
Xsensative - they may be written in upper or lowercase. In the case of
Xa conflict with an \fBfplan\fP keyword (e.g. if there is an airport
Xnamed VIA), use uppercase to prevent \fBfplan\fP from interpreting VIA
Xas a keyword. Each descriptor is listed below.
X.TP 20
X.\"-----------------
X\fBfrom\fP \fIdesignator\fP ;
XSpecifies the departure airport. \fIDesignator\fP is an airport
Xdesignator (e.g. ORD). The private and public airports.nav databases
Xare searched. It is an error if the \fIdesignator\fP cannot be found
Xin any database. (Example: \fIfrom ORD;\fP).
X.\"-----------------
X.TP
X\fBto\fP \fIdesignator\fP ;
XSpecifies the destination airport. \fIDesignator\fP is an airport
Xdesignator (e.g. ORD). The private and public airports.nav databases
Xare searched. It is an error if the \fIdesignator\fP cannot be found
Xin any database. (Example: \fIto ATL;\fP).
X.\"-----------------
X.PP
XIntermediate waypoints can be specified in three ways: by designator
X(for vors or airports in the databases), by geographic coordinates
X(latitude and longitude), or as a `distance since last turn' (useful
Xfor VFR, dead reckoning flights where it is helpful to have a
Xcheckpoint every 10 minutes or so).
X.TP 20
X\fBvia\fP \fIdesignator\fP ;
XSpecifies a navaid or airport waypoint. \fIDesignator\fP is a
Xnavaid, intersection, or airport designator (e.g. RMG). The private
Xand public vors.nav, then airports.nav databases are searched. It is
Xan error if the \fIdesignator\fP cannot be found in any database.
X(Example: \fIvia CMI;\fP).
X.\"-----------------
X.TP
X\fBvia\fP \fIlatitude\fP , \fIlongitude [, name [, city [, comment ]]]\fP ;
XSpecifies a geographic coordinate checkpoint. Use positive latitudes
Xfor north, negative for south. Use positive longitudes for west,
Xnegative for east. Use \fIdegrees.minutes\fP notation: 45.678 means 45
Xdegrees, 67.8 minutes. Up to three optional comma-separated strings
X(corresponding to the \fIname\fP, \fIcity\fP, and \fIcomment\fP,
Xstrings in the output form) may be specified. (Examples: \fIvia 33.51,
X84.38, ``Tank Farms'', ``Atlanta'', ``7nm NW of FTY'';\fP or \fIvia
X33.51, 84.38, ``Tank Farms'', ``Atlanta'';\fP or even just \fIvia
X33.51, 84.38;\fP).
X.\"-----------------
X.TP
X\fBvia\fP \fIdistance [, name [, city [, comment ]]]\fP ;
XSpecifies an `incremental' checkpoint. If positive, \fIDistance\fP is
Xa number specifying the number of \fInautical\fP miles (unless the
X\fBmi\fP keyword is specified - then statute miles) since the last
Xturn point. If negative, then the distance until the next turn point.
XIncremental waypoints are very useful for intermediate waypoints in
XVFR / dead reckoning flight, where it is often necessary to have
Xcheckpoints every 10 miles or so. They are also useful for specifying
X`end-of-climb' or `beginning-of-descent' points. The optional strings
Xare described under geographic coordinate checkpoints. Warning:
Xsuccessive `incremental' distances refer to the previous
Xnon-`incremental' checkpoint. Thus the following two waypoints
Xactually refer to the same point: \fIvia 10, ``point 1'';\fP and
X\fIvia 10, ``point 2''\fP. (Examples: \fIvia 12;\fP or \fIvia 13.4
Xmi;\fP or \fIvia 5, ``Montefusco's Lake'';\fP)
X.PP
XThe following directives are used to specify the wind and true airspeed.
X.TP 20
X\fBwind\fP \fIheading\fP \fB@\fP \fIspeed\fP ;
XSpecifies the wind speed and direction. If no wind is specified, it
Xis assumed to be calm. (Example: \fIwind 320@15;\fP).
X.TP
X\fBtas\fP \fIspeed\fP ;
XSpecifies the true airspeed. If no true airspeed is specified, time
Xestimates will not be made. The speed is assumed to be in knots unless
Xthe \fBmph\fP keyword is specified. (Example: \fItas 95;\fP or \fItas
X95mph;\fP).
X.PP
XIn order for fuel consumption computations to be made, the initial
Xamount of fuel on board and burn rate must be specified.
X.TP 20
X\fBfuel_amt\fP \fInumber\fP ;
XSpecifies the initial amount (pounds, gallons, liters, whatever) of
Xfuel on board. (Example: \fIfuel_amt 24.5;\fP).
X.TP
X\fBfuel_rate\fP \fInumber\fP ;
XSpecifies the fuel burn rate in units per hour - use the same units
Xas in the \fBfuel_amt\fP directive. (Example: \fIfuel_rate 5.4;\fP).
X.TP
X\fBfuel_used\fP \fInumber\fP ;
XSpecifies fuel burn not computable from the burn rate (e.g. for taxi
Xand climb). Use the same units as in the \fBfuel_amt\fP directive.
X(Example: \fIfuel_used 0.8;\fP).
X.PP
XThe flight altitude may be specified with the following directive. It
Xis currently simply copied to the output form, but future versions of
X\fBfplan\fP may use it to look up true airspeed and fuel economy from
Xan aircraft specific database.
X.TP 20
X\fBalt\fP \fIfeet\fP ;
XSpecifies the flight altitude for the succeeding legs. (Example:
X\fIalt 5500;\fP).
X.PP
XVOR cross fixes can be computed for each waypoint. Up to 6
Xsimultaneous fixes may be specified. By default, nav(1) automatically
Xtracks to the next waypoint (if it is a navigation aid), or from the
Xprevious waypoint. This can be disabled by the \fB-t\fP command line
Xswitch. When auto track is enabled (the default), user specified
Xvalues for nav(1) are ignored.
X.TP 20
X\fBnav (\fP \fInumber\fP \fB)\fP \fIdesignator\fP ;
XSpecifies which VOR to track in the \fInumber\fP navigation radio. It
Xis an error if no navaid named \fIdesignator\fP can be found in the
Xdatabases. (Example: \fInav(2) cmi;\fP).
X.\"-------------------------------------------
X.SH EXAMPLE
XThe following example planfile illustrates a simple flight from
XChicago O'Hare to Champaign, IL via the DuPage VOR with a 5 knot wind
Xfrom 320. True airspeed is set for 95 knots. VOR cross fixes from the
XPeotone VOR (EON) will be computed. Initial fuel is 24.5 gallons and
Xfuel economy is set to 5.4 gallons per hour.

X.SH "DESCRIPTION"
X.PP
XThe \fBfplan(5)\fP format is identical to the \fBnav(5)\fP format.
XDatabases created for \fBnav(1)\fP are compatible with \fBfplan(1)\fP.
X.PP
XThese files (\fIairports.nav\fP, and \fIvors.nav\fP) contain
Xinformation about airports and and radio navigation aids. The files
Xconsist of any number of records in the formats described below. Each
Xrecord contains a series of fields, separated by colons (:) and is
Xnull-padded to a fixed length which allows \fBfplan(1)\fP to use a
Xfast binary search algorithm for database searches. A companion
Xprogram, \fBpaddb(1)\fP, can be used to convert a text file into a
Xpadded database file. The records must occur in increasing
Xlexigraphic (alphabetical) order.
X.SH AIRPORTS DATABASE (airports.nav)
X.PP
XThe following sample record:
X.sp
X.ce 1
X"1C6:POLO, IL:RADIO RANCH:840:-01:0:41:58.7:89:33.6:122.800:CHICAGO"
X.sp
Xis for Radio Ranch airport in Polo, IL. The airport designator
Xis 1C6. Its elevation is 840 feet. The local magnetic variation is 1
Xdegree, 0 minutes east. Its geographic coordinates (latitude and
Xlongitude) are 41 degrees, 58.7 minutes north, 89 degrees, 33.6
