Nflight Early Preview (EP) 1.2 - the Newton Flight SimulatorCopyright 1997, 1998 Lee Moon.  All Rights Reserved.6/23/98Nflight(EP) 1.2 is a real-time, vector graphics, 3D flight simulator for useon the Newton MessagePad 2000 and 2100. It is loosely based on the originalRadio Shack TRS-80 "FS-1" flight simulator from SubLogic. This software iscurrently under development. Throttle control, 9 position control stick,altimeter, fuel gauge, airspeed indicator, compass heading, VOR Nav, and 3Dcockpit display are all functioning in the present preview version.Nflight Release NotesThis WAS an Early Preview release and is only a glimpse at what the finishedversion WOULD HAVE looked like. More features and fewer bugs WERE planned for thefinal release version! :-)Some of the major known bugs in this version include:1) Random lines sometimes appear in the 3D window.2) The info button indicates that Nflight will expire on 3/31/98 - this is not true - see "New and change features" below.Some of the major features that are missing in this version include:1) Artificial horizon (also useful in the fog scenarios).2) Better stall effects under low airspeed conditions (can stop in mid-air.)3) More sound effects.4) Newton Book containing Nflight instructions, aircraft characteristics,flying tips, and theory of flight.New and changed features:1) Increased "out the window" view slightly.2) Removed the expiration - Nflight is a non-expiring application now.Nflight Instructions1) Download the Nflight(EP).pkg file to your Mac or PC.2) Install Nflight(EP).pkg on your Newton 2000/2100.3) Open Extras and adjust the volume slider to a comfortable level, then tapon the Nflight(EP) icon to start Nflight.4) A "fine print" screen will open. Read this and either tap "Accept" or"Decline" to proceed. If You tap "Decline" the program will quit.5) Tap the "Settings" button to pop up a list of available scenarios. Selectone.6) Tap the "Start" button to begin the simulation. You will be placed at theend of runway number 1.7) Slide the throttle setting to 100% power. Your speed will increase tomaximum.8) When the airspeed exceeds 50 knots, tap on the stick back button(downward control stick arrow) to pull the nose up and take off.9) You're flying. The 8 direction buttons correspond to: stick forward (nosedown), stick forward & right (nose down, right turn), stick right (rightturn), stick back & right (nose up, right turn), stick back (nose up), stickback & left (nose up, left turn), stick left (left turn), stick forward &left (nose down, left turn). The center button (the "circle in a box"button) will reset the pitch and bank angles to zero - returning to straightand level flight.10) IMPORTANT NOTE: single tap on the control stick buttons (don't hold downon them). The simulation runs faster with single taps AND causes less wearand tear on the Newton screen. Also, remember to "roll out" of a turn byapplying opposite stick control. Optionally, you can quickly return tostraight and level flight by tapping the center direction button.11) SECOND IMPORTANT NOTE: the control stick buttons have 2 settings. Thefirst tap will cause a small pitch or bank angle to occur. The second tapwill invoke a larger pitch or bank angle.12) Fly freely over the 8x8 world grid (you can fly off it as well). Lookfor runway number 2 near one end of the mountain range.13) Altimeter, fuel, speed, and compass heading indicators are displayed inthe 3D window.14) Tap the close box to quit Nflight.Nflight Simulation Characteristics1) Level flight requires a throttle setting between 50% and 100%.2) Safe landing speeds occur between 50 knots and 68 knots. Airspeeds above68 knots when landing will cause a crash.3) A warning display/sound activates at 150 feet while descending with thelanding gear up. Tap the landing gear buttons to extend the landing gear.4) A warning display/sound activates above 1000 feet with the landing geardown. Tap the landing gear buttons to retract the landing gear.5) The maximum ceiling is 9,999 feet.6) The aircraft will stall at an airspeed of 50 knots or less. A warningdisplay/sound will activate during a stall condition.7) Running out of fuel in flight will cause the aircraft to assume a "safeglide" attitude. You should attempt to make a dead stick landing at eitherend of a runway to refuel.8) To refuel, land the plane and taxi to the end of a runway (within 0.1miles) and stop. The aircraft will automatically be refueled. You may thentake off again.9) Both runways have radio navigation beacons at each end. These aid inlocating the runways during flight and when taxiing for refueling. The VORNAV radio buttons are pre-programmed with the 4 beacons as follows: button 1- west end of runway 2, button 2 - east end of runway 2, button 3 -northeast end of runway 1, and button 4 - southwest end of runway 1. Tap oneof the VOR NAV buttons to display the beacon number (in [brackets]), relative bearing (+degrees are to the right, - degrees are to the left), and distance in miles.Tap the VOR NAV Off button to shut off the Nav display. When flying in oneof the fog scenarios, the VOR NAV radio becomes especially useful.Contact InformationI have ceased development of my Newton projects and have archived all of my projects and tools onto ZIP disks.  I continue to use my Newtons every day, but will not be supporting or developing any of my existing Newton applications.  Serious inquiries regarding the purchase and transfer of my source code will be considered.Lee Moonemail:  leemoon@hotmail.comweb:    http://www.gate.net/~moonclan/leemoon/index.html
