Slots Definition Plane

A leading-edge slot is a fixed aerodynamic feature of the wing of some aircraft to reduce the stall speed and promote good low-speed handling qualities. A leading-edge slot is a spanwise gap in each wing, allowing air to flow from below the wing to its upper surface. A theoretically exact point, axis, or plane derived from the true geometric counterpart of a specified datum feature. A datum is the origin from which the location or geometric characteristics of features of a part are established. Slots in ground planes divert the ground current flow(see figure), thereby producing a high ground impedance (Inductance)anda ground plane voltage drop that is the cause of increased emissionsfromthe cables connected to the board. In addition, ground planeslotswill significantly increase the crosstalk between traces thatcrossover them, and the larger loops formed by the return current.

As the coronavirus outbreak means more and more people are avoiding air travel, airlines have been forced to run empty or near-empty 'ghost flights' in order to hold onto coveted airport slots.

Term Inner Boundry	Definition A worst case boundry (that is, locus) generated by the smallest feature (MMC for an internal feature and LMC for an external feature) minus the stated geometric tolerance and any additional goemetric tolerance (if applicable) from the features departure from its specified material condition.
Term Outer Boundry	Definition A worst case boundry (that is, locus) generated by the largest feature (LMC for an internal feature and MMC for an external feature) plus the stated geometric tolerance and any additional goemetric tolerance (if applicable) from the features departure from its specified material condition.
Term Datum	Definition A theoretically exact point, axis, or plane derived from the true geometric counterpart of a specified datum feature. A datum is the origin from which the location or geometric characteristics of features of a part are established.
Term Datum Feature	Definition An actual feature of a part that is used to establish a datum.
Term True Geometric Counterpart	Definition The theoretically perfect boundry (virtual condition or actual mating envelope) or best-fit (tangent) plane of a specified datum feature.
Term Datum features subject to size variation	Definition Datum features, such as diameters and widths, differ from singular flat features in that they are subject to variations in size as well as form.
Term Datum feature simulator	Definition A surface of adequately precise form (such as a surface plate, a gage surface, or mandrel) contacting the datum feature(s) and used to establish the simulated datums.
Term Simulated datum	Definition A point, axis, ot plane established by processing or inspection equipment, such as the following simulators: surface plate, a gage surface, or mandrel.
Term Datum target	Definition A specified point, line, or area on a part used to establish a datum.
Term Dimension	Definition A numerical value expressed in appropriate units of measure and used to define the size, location, and geometric characteristis, or surface texture of a part or part feature.
Term Basic dimension	Definition A numerical value used to describe the theoretically exact size, profile, orentation, or location of a feature or a datum tatget. It is the basis from whigh permissible variations are established by tolerances on other dimensions, in notes, or in feature control frames.
Term Reference Dimension	Definition A dimension, usually without tolerance, used for information purposes only. A reference dimension is a repeat of a dimension or is derived from other values shown on the drawing or on related drawings. It is considered auxiliary information and does not govern production or inspection opertions.
Term Feature	Definition A general term appiled to a physical portion of a part, such as a surface, pin, tab, hole, or slot.
Term Axis of a feature	Definition A straight line that coincides with the axis of the true geometric counterpart of the specified feature.
Term Center plane of a feature	Definition A plane that coincides with the center plane of the true geometric counterpart of the specified feature.
Term Derived median line of a feature	Definition An imperfect line (abstract) that passes through the center points of all cross sections of the feature. These cross sections are normal to the axis of the actual mating envelope. The cross section center points are determined as per ANSI B89.3.1.
Term Derived median plane of a feature	Definition An imperfect plane (abstract) that passes through the center points of all line segments of the feature. These line segments are normal to the actual mating envelope.
Term Feature of size (FOS)	Definition One cylindrical or spherical surface, or a set of two opposed elements or opposed parallel surfaces, associated with a size dimension.
Term Individual features of size (Rule #1)	Definition Where only a tolerance of size is specified, the limits of size of an individual feature prescribe the extent to which variations in its geometric form, as well as size, are allowed
Term Maximum Material Contition (MMC)	Definition The condition in which a feature of size contains the maximum amount of material within the stated limits if size -- for example, minimum hole diameter, maximum shaft diameter.
Term Least Material Contition (LMC)	Definition The condition in which a feature of size contains the least amount of material within the stated limits if size -- for example, maximum hole diameter, minimum shaft diameter.
Term Regardless of Featue Size (RFS)	Definition The term used to indicate that a geometric tolerance or datum reference applies at any increment of size of the feature within its tolerance.
Term Resultant Contition	Definition The variable boundry generated by the collective effects of a size feature's specified MMC or LMC material condition, the geometric tolerance for that material condition, the size tolerance, and the additional geometric tolerance derived from the feature's departure from its specified material condition.
Term Virtual Condition	Definition A constant boundry generated by the collective effects of a size feature's specified MMC or LMC material condition and the geometric tolerance for that material condition.
Term Actual Size	Definition The general term for the size of a produced feature. This term includes the actual mating size and the actual local sizes.
Term Actual Local Size	Definition The value of any indiviual distance at any cross section of a feature.
Term Actual Mating Size	Definition The dimensional value of the actual mating envelope.
Term Actual Mating Envelope	Definition This term is defined according to the type of feature, as follows' a) For an external feature. A similar perfect counterpart of smallest size that can be circumscribed about the feature so that it just contacts the surface at the highest points. For example, a smallest cylinder of perfect form or two parallel planes of perfect form at minimum separation that just contact(s) the highest points of the surface(s). b) For an internal feature. A similar perfect counterpart of largest size that can be inscribed within the feature so that it just contacts the surface at the highest points. For example, a largest cylinder of perfect form or two parallel planes of perfect form at maximum separation that just contact(s) the highest points of the surface(s). For features controled by orientation or positional tolerances, the actual mating envelope is oriented relative to the appropriate datum(s), for example, perpendicular to a primary datum plane.
Term Limits of Size	Definition The specified maximum and minimum sizes.
Term Nominal Size	Definition The designation used for purposes of general identification.
Term Resultant Contition Size	Definition The actual value of a resultant contition boundry.
Term Virtual Contition Size	Definition The dimensional value of a virtual contition boundry.
Term Tangent Plane	Definition A theoretically exact plane derived from the true geometric counterpart of the specified feature surface.
Term Tolerance	Definition The total amount a specific dimension is permitted to vary. The tolerance is the difference between the maximum and minimum limits.
Term Bilateral Tolerance	Definition A tolerance in which variation is permitted in both directions from the specified dimension.
Term Geometric Tolerance	Definition The general term applied to the category of tolerances used to control form, profile, orientation, location, and runout.
Term Form Tolerance	Definition _____ tolerances control straightness, flatness, circularity, and cylindricity.
Term Flatness	Definition _______ is the condition of a surface having all elements in one plane.
