• Amendment to the document could be initiated by the Operator/Provider but performed by another entity. Type 3 Documentation (Files on Servers) • Documentation that is available from server files (e.g. .doc, .pdf files) and accessed through organization-wide networks (e.g. MS Sharepoint). The controlled version of documents may be presented or displayed either electronically or on paper, as defined by the operator. Each version of such documentation must display a version identifier and effective date. • Characteristics–Controlled content is displayed to users in conventional user files through an electronic medium, or is displayed in printed form in a paper document; whether displayed electronically or on paper, must include a version identifier and effective date. • Amendment to the document could be initiated, carried out and controlled by the Operator/Provider. See Controlled Document, Electronic Documentation, Paper Documentation. Documented The state of an operational specification as being published and accurately represented in a controlled document by the Operator/Provider. Domestic Flight A flight conducted between airports within the territories of one nation or country. Equivalent Term: Domestic Operations Driftdown The descent of a multi-engine aircraft to a planned (or predetermined) altitude after an en route failure of one engine. Driftdown (Altitude) The highest altitude, based on a planned aircraft weight, that can be maintained by a two engine aircraft after an en route engine failure. Driftdown (Performance) The minimum level of aircraft performance, achieved by limiting the takeoff weight as a means to limit the en route weight, which maximizes the driftdown altitude in critical terrain areas. For critical terrain areas, driftdown performance is maximized in order to clear all terrain along the intended route by a margin acceptable to the Operator or Authority. Dry Lease The practice whereby equipment is leased through a commercial lease agreement between lessee and lessor, and such equipment is operated by the lessee. Dry Runway The state of a runway when it is clear of contaminants and visible moisture within the required length and the width being used. See Also Contaminated Runway, Wet Runway Dual Inspection See Independent Inspection. E EDTO Critical Fuel The fuel quantity necessary to fly to an en route alternate airport considering, at the most critical point on the route, the most limiting system failure as defined by the State of the Operator. See EDTO (Extended Diversion Time Operations). EDTO Significant System An aircraft system whose failure or degradation could adversely affect the safety particular to an EDTO flight, or whose continued functioning is specifically important to the safe flight and landing of an aircraft during an EDTO diversion. See EDTO (Extended Diversion Time Operations). Electronic Flight Bag (EFB) An electronic display system intended primarily for flight deck or cabin use. EFB devices can display a variety of aviation data (e.g., checklists, navigation charts, aircraft operating manual (AOM)) or perform basic calculations (e.g., performance data, fuel calculations). The scope of the EFB system functionality may also include various other hosted databases and applications. Physical EFB devices may use various technologies, formats, and forms of communication. Physical EFB displays may be portable (Class 1), attached to an approved mounting device (Class 2), or built into the aircraft (Class 3). • A Class 1 EFB is considered a Portable Electronic Device (PED), which is part of a pilot's flight kit and is usually not attached to the aircraft or connected to its systems other than for the purpose of charging internal batteries. Typically carry-on, commercial off-the shelf systems, Class 1 EFBs may have the capability to connect to systems completely isolated from the avionics/aircraft systems (e.g., EFB system connected to a transmission media that receives and transmits data for AAC purposes on the ground only). Class 1 EFBs are typically not subject to airworthiness requirements or approvals; • A Class 2 EFB is still considered a PED and has all of the capabilities of a Class 1 EFB, but it is typically attached to the aircraft by a mounting device, connected to a data source(s), a hard-wired power source, and/or an installed antenna. As Class 2 EFBs are capable of reading data from aircraft busses they are typically subject to airworthiness requirements or approvals; • A Class 3 EFB is essentially an avionics system subject to airworthiness requirements and approvals. These range from panel mounted Multi-Function Displays (MFDs) to custom integrated airworthy systems. |
