The engine whose failure would most adversely affect the performance or handling qualities of an aircraft. (155) Critical phases of flight. Those portions of operations involving taxiing, takeoff and landing, and all flight operations below 3050 m (10,000 feet), except cruise flight. (156) Critical power-unit(s) . The power-unit(s) failure of which gives the most adverse effect on the aircraft characteristics relative to the case under consideration. Note – On some aircraft there may be more than one equally critical power-unit. In this case, the expression “the critical power-unit” means one of those critical power-units. (157) Cross country. A flight between a point of departure and a point of arrival following a pre-planned route using standard navigation procedures. (158) Cross-country time. That time a pilot spends in flight in an aircraft which includes a landing at a point other than the point of departure and, for the purpose of meeting the cross-country time requirements for a private pilot licence (except with a rotorcraft rating), commercial pilot licence, or an instrument rating, includes a landing at an aerodrome which must be a straight-line distance of more than 50 nautical miles from the original point of departure. (159) Cruise climb. An aeroplane cruising technique resulting in a net increase in altitude as the aeroplane mass decreases. (160) Cruise relief pilot. A flight crew member who is assigned to perform pilot tasks during cruise flight to allow the PIC or co-pilot to obtain planned rest. (161) Cruising level. A level maintained during a significant portion of a flight. (162) Current flight plan. The flight plan, including changes, if any, brought about by subsequent clearances. (163) Curriculum. A set of courses in an area of specialization offered as part of a training programme. Check TRAINAIR Plus training manual (164) Danger area. An airspace of defined dimensions within which activities dangerous to the flight of the aircraft may exist at specified times. (165) Dangerous goods. Articles or substances which are capable of posing a risk to health, safety, property or the environment and which are shown in the list of dangerous goods in the ICAO Technical Instructions (see definition below) or which are classified according to those Instructions. Note - Dangerous goods are classified in ICAO Annex 18, Chapter 3. (166) Dangerous goods accident. An occurrence associated with and related to the transport of dangerous goods which results in fatal or serious injury to a person or major property damage. (167) Dangerous goods incident. An occurrence, other than a dangerous goods accident, associated with and related to the transport of dangerous goods, not necessarily occurring on board an aircraft, which results in injury to a person, property damage, fire, breakage, spillage, leakage of fluid or radiation or other evidence that the integrity of the packaging has not been maintained. Any occurrence relating to the transport of dangerous goods which seriously jeopardises an aircraft or its occupants is deemed to constitute a dangerous goods incident. (168) Dangerous goods transport document. A document specified by the ICAO Technical Instructions for the Safe Transportation of Dangerous Goods by Air. It is completed by the person who offers dangerous goods for air transport and contains information about those dangerous goods. The document bears a signed declaration indicating that the dangerous goods are fully and accurately described by their proper shipping names and UN numbers (if assigned) and that they are correctly classified, packed, marked, labelled and in a proper condition for transport. Note: See definition below for Technical Instructions. (169) Data link communications. A form of communication intended for the exchange of messages via a data link. (170) Data link recording system. A device that records those messages whereby the flight path of the aircraft is authorised, controlled directly or indirectly, and which are relayed over a digital data-link rather than by voice communication. Source: EUROCAE ED-155 "Minimum Performance Specification for Lightweight Flight Recording Systems," July 2009, paragraph 1-1.5.1. (171) Deadhead transportation. Time spent in transportation on aircraft (at the insistence of the AOC holder) to or from a crew member’s home station. (172) Decision altitude (DA) or decision height (DH). A specified altitude or height in a 3D instrument approach operation at which a missed approach must be initiated if the required visual reference to continue the approach has not been established. Note 1: Decision altitude (DA) is referenced to mean sea level and decision height (DH) is referenced to the threshold elevation. Note 2: The required visual reference means that section of the visual aids or of the approach area which should have been in view for sufficient time for the pilot to have made an assessment of the aircraft position and rate of change of position, in relation to the desired flight path. In Category III operations with a decision height that required visual reference is that specified for the particular procedure and operation. Note 3: For convenience where both expressions are used they may be written in the form “decision altitude/height” and abbreviated “DA/H”. (173) Defined point after takeoff (DPATO). The point, within the takeoff and initial climb phase, before which the Class 2 helicopter's ability to continue the flight safely, with one engine inoperative, is not assured and a forced landing may be required. (174) Defined point before landing (DPBL). The point, within the approach and landing phase, after which the Class 2 helicopter's ability to continue the flight safely, with one engine inoperative, is not assured and a forced landing may be required. (175) Design landing mass. The maximum mass of the aircraft at which, for structural design purposes, it is assumed that it will be planned to land (176) Design takeoff mass. The maximum mass at which the aircraft, for structural design purposes, is assumed to be planned to be at the start of the take-off run. (177) Design taxing mass. The maximum mass of the aircraft at which structural provision is made for load liable to occur during use of the aircraft on the ground prior to the start of take-off. (178) Designated Examiner. Any person designated by the Authority to act as a representative of the Authority in examining, inspecting, and testing persons for the purposes of issuing licences, ratings, or certificates. (179) Detect and avoid. The capability to see, sense or detect conflicting traffic or other hazards and take the appropriate action. (180) Directly in charge. As applied to an Approved Maintenance Organisation in Part 6 - Means an appropriately licensed person(s) having the responsibility for the work of an approved maintenance organisation that performs maintenance, preventive maintenance, alterations, or other functions affecting aircraft airworthiness. A person directly in charge does not need to physically observe and direct each worker constantly but must be available for consultation on matters requiring instruction or decision from higher authority. (181) Director. The Director of Civil Aviation appointed under the [MODEL CIVIL AVIATION ACT of STATE]. (182) Discrete source damage. Structural damage of the aeroplane that is likely to result from: impact with a bird, uncontained fan blade failure, uncontained engine failure, uncontained high-energy rotating machinery failure or similar causes. (183) Dry lease. The lease of an aircraft without the crew. (184) Dual instruction time. Flight time during which a person is receiving flight instruction from a properly authorised pilot on board the aircraft. (185) Duty. Any task that flight or cabin crew members are required by the operator to perform, including for example, flight duty, administrative work, training, positioning and standby when it is likely to induce fatigue. (186) Duty period. As related to an air operator, a period which starts when flight or cabin crew personnel are required by an operator to report for or to commence a duty and ends when that person is free from all duties. (187) Duty time. The total time from the moment a person identified in these regulations begins, immediately after a rest period, any work on behalf of the certificate holder until that person is free from all restraint associated with that work.

(189) Effective length of the runway. The distance for landing from the point at which the obstruction clearance plane associated with the approach end of the runway intersects the centreline of the runway to the far end. (190) Elevated heliport. A heliport located on a raised structure on land. (191) Enhanced vision system (EVS). A system to display electronic real-time images of the external scene achieved through the use of image sensors. (192) Emergency locator transmitter (ELT).
