پیرو پست های قبلی در این پست به بررسی 10 تعریف مربوط به فصل DEF از Air-Ops می پردازیم.
در میان ده مورد موجود در این پست موارد زیر کاربردی تر هستند :
(51) ‘Extended diversion time operations (EDTO)’
means any operation by an aeroplane with two or more turbine engines where the diversion time to an enroute alternate aerodrome is greater than the threshold time established by the State of the Operator.
???
(51a) ‘EDTO critical fuel’
means the fuel quantity necessary to fly to an en-route alternate aerodrome considering, at the most critical point on the route, the most limiting system failure.
(51b) ‘EDTO significant system’
means an aeroplane 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 aeroplane during an EDTO diversion.
(52) ‘Final Approach and Take-Off area (FATO)’
means a defined area for helicopter operations, over which the final phase of the approach manoeuvre to hover or land is completed, and from which the take-off manoeuvre is commenced. In the case of helicopters operating in performance class 1, the defined area includes the rejected take-off area available;
(53) ‘Flight Data Monitoring (FDM)’
means the proactive and non-punitive use of digital flight data from routine operations to improve aviation safety;
punitive : مجازات
proactive : فعالانه
(54) ‘Flight Simulation Training Device (FSTD)’
means a training device which is:
(a) in the case of aeroplanes,
a full flight simulator (FFS),
a flight training device (FTD),
a flight and navigation procedures trainer (FNPT),
or a basic instrument training device (BITD);
(b) in the case of helicopters, a full flight simulator (FFS), a flight training device (FTD) or a flight and navigation procedures trainer (FNPT);
(55) ‘Fuel ERA aerodrome’
means an ERA aerodrome selected for the purpose of reducing contingency fuel;
(56) ‘GBAS Landing System (GLS)’
means an approach landing system using ground based augmented global navigation satellite system (GNSS/GBAS) information to provide guidance to the aircraft based on its lateral and vertical GNSS position.
It uses geometric altitude reference for its final approach slope;
(57) ‘Ground emergency service personnel’
means any ground emergency service personnel (such as policemen, firemen, etc.)
involved with helicopter emergency medical services (HEMSs) and whose tasks are to any extent pertinent to helicopter operations;
(58) ‘Grounding’
means the formal prohibition of an aircraft to take-off and the taking of such steps as are necessary to detain it;
detain : بازداشت
(59) ‘Head-Up Display (HUD)’
means a display system which presents flight information to the pilot’s forward external field of view and which does not significantly restrict the external view;
(60) ‘Head-Up Guidance Landing System (HUDLS)’
means the total airborne system that provides head-up guidance to the pilot during the approach and landing and/or missed approach procedure. It includes all sensors, computers, power supplies, indications and controls;
