8What validity period must be considered for the forecast weather conditions when nominating an ETOPS/EDTO en-route alternate aerodrome?
Ответ по ключу базы
- A. The period commencing at the earliest potential time of landing and ending 1 hour after the latest nominated time of use of that aerodrome.
9What is a parameter included necessarily to company EDTO approval?
10What Maximum EDTO diversion time for MY FREIGHTER (Boeing 767)?
11Actual diversion time in flight may be higher than the diversion time used to establish the EDTO area of operation, provided that the planned route remains within the applicable still-air range from an en- route alternate aerodrome.
12Maximum Diversion Distance is used for:
13EDTO Area of Operations:
Ответ по ключу базы
- B. Represented by the area enclosed within arcs/circles centered on the selected EDTO en-route alternate aerodromes, using the approved maximum diversion distance.
14EDTO Entry Point (EEP) is:
Ответ по ключу базы
- A. The first point on the route that is beyond the applicable EDTO threshold time/distance from an en-route alternate aerodrome.
15An EDTO route may have multiple EDTO sectors, separated by non-EDTO segments.
16What is a point on the route located at the same flying time from two selected EDTO en-route alternate aerodromes?
17When one of ETPs (usually last on the route) can become critical point (CP)?
Ответ по ключу базы
- B. When the carriage of additional EDTO fuel reserves is required, because fuel difference between the standard fuel expected to be on board (fuel to continue) and the required EDTO diversion fuel (fuel to divert) is minimum or negative.
18One-engine-inoperative diversion speed is used for:
Ответ по ключу базы
- A. Defining the maximum diversion distance / area of operation.
19The size of EDTO area of operations depends on:
Ответ по ключу базы
- A. The maximum diversion range, the one-engine-inoperative diversion speed, and the number and location of the selected EDTO en-route alternate aerodromes.
20What is a difference between standard and EDTO fuel calculations?
Ответ по ключу базы
- C. Defining of additional fuel (critical fuel reserve), if this fuel reserve is required for particular flight.
21How are ETOPS/EDTO en-route alternate aerodrome planning minima determined?
Ответ по ключу базы
- A. By adding the applicable additional limits to the published operating minima for the available approach procedure.
22The EDTO dispatch planning minima apply until dispatch.
23What are the crew procedures necessary to conduct additionally during EDTO flight?
Ответ по ключу базы
- B. Aircraft systems monitoring; weather monitoring; fuel monitoring, diversion planning with respect to all operational considerations.
24If the engine failure occurred during EDTO segment, what operational factors must be considered by the CPT during decision-making?
Ответ по ключу базы
- C. Closest adequate airport is preferable, but actual weather situation (alternate and en-route) and all another operational factors must be considered.
25Select the correct decision in case of impossibility to meet EDTO dispatch requirements before particular flight:
Ответ по ключу базы
- B. Select another route, aircraft or delay the flight until all EDTO dispatch requirements are met and required procedures are completed.
26According to ICAO 10085, what additional limits are added to the operating minima for a non- precision approach or circling approach when determining ETOPS en-route alternate planning minima?
Ответ по ключу базы
- A. Authorised MDH/MDA plus 400 ft and authorised visibility plus 1500 m.
27According to ICAO 10085, what additional limits are added to the operating minima for precision approach when determining ETOPS en-route alternate planning minima?
Ответ по ключу базы
- A. Authorised DH/DA plus 200 ft and authorised visibility plus 800 m.
28In the event of a diversion on an EDTO flight, the flight crew is not obligated to divert to the primary EDTO alternate aerodrome listed on the flight plan and may choose a different aerodrome as the nearest suitable landing site if this is deemed to be a safer course of action based on prevailing operational conditions.
29An aeroplane should not be released on an EDTO flight unless the air operator’s operations manual and/or as applicable the EDTO flight operations manual (EFOM) contain(s) sufficient performance data to support all phases of any applicable EDTO operation, including flight preparation and en-route operations
30What should be verified/completed before dispatching an ETOPS/EDTO flight?
Ответ по ключу базы
- A. Aircraft EDTO serviceability/status including applicable MEL/CDL restrictions, ETOPS/EDTO en-route alternate selection and weather, critical fuel planning, and required flight documentation.
31According to ICAO Doc 10085, which ICAO provisions does the EDTO Manual support?
Ответ по ключу базы
- A. Annex 6 - Operation of Aircraft, Part I, Section 4.7 and Attachment C.
32What must be verified before proceeding beyond the EDTO Entry Point (EEP)?
Ответ по ключу базы
- A. The forecast weather at the EDTO alternate aerodromes identified on the OFP is equal to or exceeds the published operating minima for the expected runway and approach procedure during the applicable validity period.
33For an aircraft with either 120-minute or 180-minute maximum approved diversion time, an operator may request an increase in the operator’s approved diversion time for specific routes, provided that the requested diversion time does not exceed either 115% of the maximum approved diversion time or the time-limited system capability minus 15 minutes.
34Which documentation should be provided to the flight crew before an ETOPS/EDTO flight?
Ответ по ключу базы
- A. NOTAMs, weather forecasts/reports, OFP, ATS flight plan with required ETOPS/EDTO en-route alternates, and relevant route/EDTO chart or plotting chart.
35An extension of the operator’s approved diversion time up to 115% of the maximum approved diversion time:
Ответ по ключу базы
- B. Must take into account the aeroplane’s most limiting time-limited system capability, including cargo fire suppression capability where applicable.
36The operator’s approved diversion time is an operational limit that should not exceed either: the maximum approved diversion time, or the time-limited system capability minus 15 minutes.
37Choose the correct statement:
Ответ по ключу базы
- A. The 60-minute area of operation and associated 60-minute threshold distance calculation is normally based on a High Engine Inoperative speed up to the maximum permissible operating speed or Mach number (VMO/MMO according FCOM limitations) in order to maximize the area of operation.
