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 242A1 locomotive and standard gauge track at some model railway scales. This page lists the most relevant model railway scale standards in the world. Most standards are regional, but some have followers in other parts of the world outside their native region, most notably NEM and NMRA.
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 ...
Modern-day inspection cars now use multiple NDT methods. Induction and ultrasound methods can be used in rail inspection cars and operate at testing speeds of more than 30 mph (48 km/h). Increased Camera systems for detection of broken joint bars or missing bolts. Eddy Current systems for the detection of near-surface defects.
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 ...
Video / image inspection systems [ edit ] These systems rely on an array of video devices in various locations between the rails and either side of the track, looking for particular bogie components (such as brake beam, springs, friction wedges, etc) and this data is then put through image analysis to determine if there are maintenance issues.

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.
