FW сказал(а):может я что-то недопонимаю, объясните- какое отношение имеет ВСУ на А320 например к ЕTOPS полётам? С отказвшим генератором, всё равно по ЕTOPS не полетишь, тут МEL не поможет.
На А320 без генератора по ETOPS не вылетают:
20-01 AC Main Generation
(IDG, GCU, Line Contactor)
(E)
C 2 1 ∗ (o) (m) Except for ETOPS, one may be
inoperative provided :
1) APU and AC auxiliary generation are
operative and used throughout the
flight, and
2) APU fuel pump is operative, and
3) APU oil consumption is checked
adequate for the intended flight, and
4) All busses can be powered, and
5) Indications and warnings for the
remaining AC main generation and the
AC auxiliary generation are operative,
and
6) Flight altitude is limited to
33,500 ft, and
7) Fuel recirculation system associated
with the operative IDG is checked
operative prior to each flight, and
8) Galley automatic shedding is
operative.
По APU A320 MEL говорит:
10-01 Power Plant (APU)
(E) (P)
C 1 0 ∗ (o) a) Except for ETOPS, may be
inoperative.
- or -
A 1 0 ∗ (o) b) Except for ETOPS beyond 120
minutes, may be inoperative for four
(4) flights.
- or -
D 1 0 ∗ (o) (m) c) Except for ETOPS, may be
inoperative provided the APU is
deactivated or removed.
Для вылета А310 по ETOPS 120+ нужен работоспособный APU (для запуска в полете в случае отказа одного из генераторов)
Except for ETOPS beyond 120
minutes, may be inoperative provided
the APU is deactivated or removed.
Для А330 проблем нет:
May be inoperative provided the APU
is deactivated or removed.
Отказ генератора на А330 тоже не влияет на ETOPS:
AC Main Generation
(IDG, GCU, Line Contactor)
C 2 1 ∗ (o) (m) One may be inoperative provided :
1) APU and AC auxiliary generation are
operative and used throughout the
flight, and
2) All busses can be powered, and
3) Indications for the remaining AC main
generation and the AC auxiliary
generation are operative, and
4) There is no ELEC IDG 1(2) OIL SYS
FAULT caution associated with the
IDG of the operative AC main
generation displayed on ECAM E/WD,
and
5) There is no FUEL APU AFT PUMP
FAULT caution displayed on ECAM
E/WD, and
6) When the AC main generation 2 is
inoperative, the automatic switching of
the essential electrical network power
supply from AC BUS 1 to AC BUS 2 is
checked operative before the first flight
under present MEL item and once
each day, and
7) The APU aft pump shedding in land
recovery configuration is checked
operative before the first flight under
present MEL item and once each
week.
8) The APU oil quantity is checked to be
adequate for the intended flight.
А откуда возьмутся после выключения двигателей на стоянке? Разве что наземники еще до выключения двигателей воткнут GPU и AC, но они, как правило, неторопливы.FW сказал(а):а если ВСУ не включать, то "воздуха и электричества" не будет?
