Print: (P)
Select Preview from dialog to check margins, no. of pages etc. 
Select Print from dialog to start printout of your planned flight. (not available 
in Demo version)
This includes Fuel,Wt & bal and frequency details.

Nav/GPS:
In order to use this facility in the registered version the S3a must be connected to 
an NMEA0183 compatible GPS receiver via the 3-link, However,
In the demo version this module is simulated and your plan is followed as if you are 
flying the  route accurately.( the demo can be speeded up by using a high speed
in the planning stage)
The first time after planning or editing a route, a map of the immediate area around 
the planned flight is built and stored in memory and a Menu is presented.
(In the registered version menu options are offered to record incoming GPS data
and replay via the moving-map or CDI display)

CDI:
With this option a CDI display is shown enabling you to navigate your planned flight. 
The display shows the following:
No. & Name of w/pt, Hdg(m) to maintain a centred needle, Range to w/pt, Groundspeed, 
Current Trk(m).
CDI display with To/From flag showing off track error
Sensitivity, which is toggled with the space bar,each dot can represent 1nm or .25nm  
...ENR/APP
OBS, which is automatically set to Trk(m) to w/pt but can be adjusted with cursor arrows
(Psion+arrow for 10 deg steps)
Real time clock, ETE (elapsed time to w/pt),  ETA to wpt , Lat/Long position
Adjust your Hdg to keep the needle centred and you will be on track.
If at any point you manually centre the needle (cursor keys) with TO flag showing, 
the OBS reading is then your QDM direct to the waypoint.
As you pass each wpt the next one is auto-selected
You can advance to the next wpt at any time by pressing <Enter>
If you need to divert or go directly to any wpt press <Diamond>, then enter the name.
The GPS plan is cancelled, the CDI needle is centred and the OBS reads the QDM direct 
to new wpt, enabling you to navigate direct to this position.
To resume planned route, Press <Esc> to quit and select Refresh from GPS Menu. (not 
available in Demo version)
Press <Esc> to return to GPS Menu

Moving-Map:
This option maps your planned trk(t), all airfields (in database) along planned trk 
(+ all navaids if selected from Preferences) all UK class D airspace, UK coastline 
and your present position(flashing cursor) as received from GPS data.
The righthand side of display shows: Wpt no. & Name,  Trk(m), Range to wpt, Left or 
right cross track error (xte), QDM direct to wpt, Groundspeed, UTC time, ETE & ETA 
to wpt, Mini CDI display(1nm dots), Lat/Lon position and no. of satellites in use.
Press <Diamond > for Go_To function (as in CDI option).
Press <Tab> to adjust Zoom level of Map  (15-256nm across screen). 
NM scale shown at base of map.
Press <Enter> to advance to next wpt.
Press <Esc> to return to GPS Menu.
Press <Menu> to toggle ICAO Airfield names/Full names.
Press <up,down,left,right cursor arrows> to shift map in relevant direction.
Press <Help> to centre aircraft in map

To return to flightplan mode select EXIT from menu or <Esc>.
************************************************************************************
In this demo the simulation GPS routine is launched as a seperate process and if
you shell out to the system menu it will be left running in the background, whereupon
it will be necessary to press shift\system to cycle all running applications until
you are back to the GPS demo 
************************************************************************************

The GPS details are held so long as the current plan is not erased or changed or you 
do not exit SIERRA 6.0. ( You can switch off <Psion-OFF> without losing any data)

The other utilities of SIERRA 6.0 are as follows:

Search: (O)
Enter the name of an airfield or navaid ident and then the range(nm)-max 60nm. 
A list of all navaids within that range together with their distance and frequency 
is shown. <any key>

Fix/divert: (K)
This option gives your lat/long position and RNAV co-ordinate from a VOR/DME, VOR/VOR 
or VOR/NDB fix.
Input  ident VOR1. Input QDR ( centred VOR needle with FROM flag). If using DME Input 
now and press <Enter> . [If you leave DME at 0 and press <Enter> you can select a 
second VOR for crosscut.]
RNAV co-ordinate and Lat/Lon Position is shown.
To plan a diversion select 'Nearest Airfield' or 'Choose Airfield'.
If you select 'Choose Airfield' enter name..min 4 letters and <Enter> when it is found. 
The QDM, dist and freq are shown.
<Esc> to return to position dialog or <Enter> to access the planning section where you 
can enter TAS,Wind vel. etc. in order to get Hdg(m) & time to the diversion. 
(N.B. By selecting <Hdg(m)> the current plan is erased and the diversion replaces it.
This enables you to use the 'GPS' option to navigate to the diversion.)
If you select 'nearest airfield' the QDM, distance and frequency(s) to the nearest 
airfield within 35nm is shown. Continue as above.

Hold: (H)
Enter TAS,wind vel(m) and inbound Trk(m) as prompted to get inbound Hdg(m) and outbound 
Hdg(m) & time for a standard 4min holding pattern.
The outbound heading is computed as 3 times the drift of inbound heading (max. 30 deg).
If this is within 30 deg of wind direction this is reduced to 2 times drift.The outbound 
time is reduced/increased by 1 sec/knot of headwind/tailwind.
<S> for stopwatch function or <Enter> for menu

Conversions: (C)
 Select a group from the menu and enter a value in any unit , press <Enter> to get a 
simultaneous conversion .
For volume to weight conversions, first enter a specific gravity ( default 0.72 ) 
<Esc for menu>

Morse: (M)
Enter a letter or ident for a visual/aural morse code check.<Esc for menu>

Frequency: (Q)
Enter name of  airfield or navaid ident to check the frequency.
Press <Tab> to add to Frequency Window.

X/wnd: (X)
Enter runway heading (2 digit e.g. 21, 03, etc.) and wind direction(3 digit) and 
speed.The crosswind and headwind components are displayed (a minus indicates a 
tailwind)  <Esc>

Stopwatch: (S)
<Enter> to start. <Enter> for reset with restart. <L> for laptime.  <Esc> for stop.

More Utilities: (+)
Select to display a menu with additional utilities.

Cost:

Now enter the UTC offset (e.g. in the UK this will be 0 in winter and 1 in summer) 
<Enter>
The sunrise, sunset, Civil dawn and Civil dusk times are displayed.
If you wish to calculate these times for a particular LAT/LONG, enter the nearest 
airfield and then edit the displayed LAT/LONG. The date can also be edited to a future 
date if required.

Press/Dens alt:
Input Area QNH(mb) and your altitude or airfield elevation(ft)
The pressure altitude is displayed.Now enter the outside air temperature (C) to show 
the density altitude.

ROD/TOD:
Input current altitude (ft), desired altitude (ft) and groundspeed (kts). 
Now input either Rate of Descent(fpm) or Top of Descent(nm),and the other is calculated.

Critical Point:
The critical point is the point where it takes equal time to fly to the destination or 
back to the point of departure. 
Enter total distance (nm), Track (t), Wind direction and speed, and Full Power TAS (kts). 
This will give the critical point assuming there is no engine failure. (leave Reduced 
Pwr TAS set at 0)
To calculate the critical point in the event of an engine failure on multi engine 
aircraft, proceed as above but enter the Reduced Pwr TAS. (the engine failure is assumed 
to occur at the worst possible time i.e. not until the critical point is reached)

Point of no Return:
The point of no return is the furthest point that an aircraft can fly away from a given 
airfield and return to that airfield, having consumed a specified amount of fuel.
Enter endurance (mins) minus any reserve required at return to point of departure. 
Enter track (t), wind direction (t), wind speed (kts) and normal TAS (kts). 
The time and distance to PNR is calculated when you press <Enter>
To calculate the PNR in the event of an engine failure, proceed as above and set the 
`Failed engine` line in dialog to `Yes`.(it is not necessary to enter Endurance in this 
instance) Now enter Reduced Pwr TAS (kts), Normal Pwr fuel flow (lbs or kg per hour), 
Reduced Pwr fuel flow and Total fuel (lbs,kg) minus any reserve. 
Press <Enter> to show time and distance to PNR.

Database/
All operations are  directed to the current Disk in use. (shown in status window)
(N.B. set write protect switch on side of your disk to 'write' before attempting to
