Ascending on a decompression buoy while slightly negatively buoyant makes accurate depth and ascent rate control relatively simple, by maintaining light tension on the line as it is reeled in, at the cost of carrying the equipment, a slightly longer time at depth during deployment, a few litres of gas for inflation, and the competence to deploy ...
Hierarchy of hazard control is a system used in industry to prioritize possible interventions to minimize or eliminate exposure to hazards. [ a ] It is a widely accepted system promoted by numerous safety organizations.
Decompression in the context of diving derives from the reduction in ambient pressure experienced by the diver during the ascent at the end of a dive or hyperbaric exposure and refers to both the reduction in pressure and the process of allowing dissolved inert gases to be eliminated from the tissues during this reduction in pressure.
A A-grade Also aid climbing grade. The technical difficulty grading system for aid climbing (both for "original" and an adapted version for "new wave"), which goes: A0, A1, A2, A3, A4, A5 and up to A6 (for "new wave"). See C-grade. Abalakov thread Abalakov thread Also V-thread. A type of anchor used in abseiling especially in winter and in ice climbing. ABD Also assisted braking device. A term ...
In the case of objects outside the Solar System, the ascending node is the node where the orbiting secondary passes away from the observer, and the descending node is the node where it moves towards the observer. [5], p. 137. The position of the node may be used as one of a set of parameters, called orbital elements, which describe the orbit.
For Bézier curves, it has become customary to refer to the -vectors in a parametric representation of a curve or surface in -space as control points, while the scalar-valued functions , defined over the relevant parameter domain, are the corresponding weight or blending functions.
The FAA publicly identified an “unsafe condition” that could result in a “loss of control” of certain Boeing 737 Max jets because of “nonconforming” installation of spoiler control wires.
The cockpit of a Slingsby T-67 Firefly two-seat light airplane.The flight instruments are visible on the left of the instrument panel. Flight instruments are the instruments in the cockpit of an aircraft that provide the pilot with data about the flight situation of that aircraft, such as altitude, airspeed, vertical speed, heading and much more other crucial information in flight.
