Part 91 is general operating rules for all aircraft. General aviation flights are conducted under this part. Part 91, Subpart (K) prescribes operating rules for fractional ownership programs. Part 107 (FAA sUAS Part 107) specifies regulations to fly under the Small UAS Rule, or small unmanned aircraft systems in the National Airspace System ...
A piece of the wreckage of Air New Zealand Flight 901, which crashed in Antarctica in 1979, despite being equipped with a GPWS.All 257 people on the plane died. Beginning in the early 1970s, a number of studies looked at the occurrence of CFIT accidents, where a properly functioning airplane under the control of a fully qualified and certificated crew is flown into terrain (or water or ...
AC 91–57() is an FAA Advisory Circular (AC) (Subject: Exception for Limited Recreational Operations of Unmanned Aircraft) that provides interim safety guidance to individuals operating unmanned aircraft, commonly known as drones, but inclusive of flying model aircraft, for recreational purposes in the National Airspace System of the United States.
Airfix Railway System Multiple Train Control (MTC) was an analog system introduced in 1979 and used 20 V sinusoidal alternating current on the track with a superimposed control signal. It can control up to 16 locomotives, which a maximum of 4 at a time be controlled simultaneously.
The term HOn30 (and sometimes HOn2½) is generally used when modelling American prototypes while H0e is used for European prototypes. In Britain, the term OO9 is used. [1] All these terms refer to models of narrow-gauge railways built to the world's most popular model railway scale of HO (1:87) but using a track gauge of 9 mm (0.354 in)—the gauge used for N scale models of standard-gauge ...
As the railroad has evolved from block stations and control towers to a centralized dispatching system, they have also moved to more advanced inspection tools. The technologies in use today vary from a simplistic paddle and switch to infrared thermography, laser scanning, and even ultrasonic audio analysis. These devices are used to inspect ...

Model railroaders Tony Koester and Steve King had quickly become friends as they developed their interest in proto-freelancing (developing a freelanced railroad based on prototype railroads and practices ) and railroad operations. The V&O was greatly influenced by prototype railroads even as they continued to move forward while the V&O remained ...
