Fisher FP-202 Koala

The Fisher FP-202 Koala and Super Koala are a family of Canadian single and two seat high wing, conventional landing gear, single engined light kit aircraft designed for construction by amateur builders. Both aircraft were inspired by the design of the Piper J-3 Cub and strongly resemble that design.

Fisher Flying Products was originally based in Edgeley, North Dakota, USA but the company is now located in Woodbridge, Ontario, Canada.

Development

The FP-202 was designed by Fisher Aircraft in the United States in 1981 and was intended to meet the requirements of the US FAR 103 Ultralight Vehicles category, including that category's maximum 254 lb (115 kg) empty weight. The design goal was to provide ultralight pilots with an aircraft that looked like and flew like the classic Piper Cub, without the regulation that goes with owning a type certified aircraft. The FP-202 can achieve an empty weight of 250 lb (113 kg) when equipped with a lightweight, two-stroke engine.

The Super Koala was first flown in 1983 and has two side by side seats arrangement. With its 400 lb (181 kg) empty weight and 830 lb (376 kg) maximum gross weight, the Super Koala was intended for the US Homebuilt aircraft category.

Double-precision floating-point format

Double-precision floating-point format is a computer number format that occupies 8 bytes (64 bits) in computer memory and represents a wide, dynamic range of values by using a floating point.

Double-precision floating-point format usually refers to binary64, as specified by the IEEE 754 standard, not to the 64-bit decimal format decimal64.

IEEE 754 double-precision binary floating-point format: binary64

Double-precision binary floating-point is a commonly used format on PCs, due to its wider range over single-precision floating point, in spite of its performance and bandwidth cost. As with single-precision floating-point format, it lacks precision on integer numbers when compared with an integer format of the same size. It is commonly known simply as double. The IEEE 754 standard specifies a binary64 as having:

This gives 15–17 significant decimal digits precision. If a decimal string with at most 15 significant digits is converted to IEEE 754 double precision representation and then converted back to a string with the same number of significant digits, then the final string should match the original. If an IEEE 754 double precision is converted to a decimal string with at least 17 significant digits and then converted back to double, then the final number must match the original.
