Charts & Reference

Over 75 charts, references, and graphs showing, aircraft performance relationships
such as aileron size, gload vs stall speed, prop dia vs mach speed, speed vs turn
radius, etc.

Graph Paper

Common graph paper needed by the design engineer for working with
charts, graphs, and drawings.

Calculator

Online scientific calculator.

Formula Solving

Instructions on how to to solve algebraic formulas.

Atmosphere Data

This program provides detailed information on the atmosphere in
table format according to altitude. Not only does it provide customary values
for air density, temperature, and pressure, but it also provides ratios,
speed of sound, and kinematic viscosity.

Capacitor Value

Electrical reference shows numbering and color code values for capacitors.

Engine Estimated HP

Using the torque or volume of an engine, the estimated HP can be
calculated for a given rpm.

Power Required

Using weight, L/D, and speed, this program will calculate power required.
Power is the best way to
calculate piston engine performance. In turbine powered aircraft thrust
is the most useful way to calculate aircraft performance because
turbine engine thrust is very predictable.
However, piston engine aircraft do not
lend themselves to predictable thrust
measurement because of changing prop pitch, RPM, and carburetor manifold
pressure.

Prop Angle

Given propeller pitch, this program will show the angle at
various radius stations of the prop.

Prop Java prop designer (requires Java)

Complete prop design using Java.

Prop Pitch

By providing the estimated cruise speed and engine RPM at that speed, this program will
calculate the suggested prop pitch.

Prop Speed

Use this program to design the optimum propeller length to
utilize the full horse power for your engines RPM.

Prop Static Thrust

This program provides a close approximation of prop thrust
for a given propeller design.

Resistor Identification

Color charts and embedded JS program to make resistor identification easy.

Sheet Bending

Tables and information for making bends in sheet metal.

Speed Design Speeds

Just provide stall and cruise speed at 75% power. Then this program
calculates Gloads and design speeds such as flutter and dive tests,
VNE, etc. Displays the requirements for all licensed category aircraft.

Speed Maximum

Get the maximum speed by entering HP, CD, and wing area. You can also
play whatif for different types of props and altitudes.

Speed Stall

After providing gross weight and simple wing information such
as wing area, this program will provide the aircraft stall speed.
You can also play whatif for different wing shapes and altitudes.

Speed True airspeed

This program requires you to enter altitude, temperature, and indicated,
then it will calculate the true airspeed.

Tail Size

This program calculates the size of the horizontal and vertical tail.

Takeoff Acceleration

All you will need to enter is take off distance and the start to
lift off time in seconds. The acceleration will be calculated for you.

Takeoff Distance

This program requires you to enter a known take off distance and weight,
then it will calculate a new distance based on changes to weight.

Transistor Specs

Electrical reference, case styles, and pinouts for the 50 most
common transistors used in circuits.

Trig Angles

Solves for all trigonometry side angle problems.

Volume of Shapes

This program gives the volume of cones, cylinders, cubes, spheres,
and pyramids.

VW Eng Specs & Formulas

This program provides data, formulas, and tables to calculate VW
engine performance  i.e. factory specs, compression ratio,
deck volume, horse power, bolt torque values.

Wind Load

This program calculates the force on structures given there
shape and air speed in MPH.

Wing Area

This program requires you to enter weight, clmax, and speed(mph),
then it will calculate the required wing area.
