you don't know how a gas turbine engine works?Originally posted by ceecookie:Cannot start engine and self-reverse ah?
unfortunately the airplanes do not have a key to turn on the engineOriginally posted by ceecookie:Cannot start engine and self-reverse ah?
the previous thread was started by me and had the incident happened at SYD instead of SIN.Originally posted by caleb_chiang:what misleading information?
quoting myself in the previous topic "got refund?"Originally posted by Pitot:i wonder all those flying the suites one.. how sia.. price diff very big.
its okay... wah ur info quite fast also horOriginally posted by Pitot:thanks for the correction. due to misleading info, previous thread has been deleted.
shld have in one way or another...Originally posted by kopiosatu:quoting myself in the previous topic "got refund?"

Singapore Airlines now holds the record for the first Airbus A380 to be stuck on a grass verge. None were hurt, except for Singapore Airlines, who also suffered the ignominy of having this piece of news achieving Â“most popular storyÂ” on CNNÂ’s website yesterday, no thanks to the misleading headline.
For punters who buy 4D numbers of accident vehicles, the planeÂ’s registration is Â“9V-SKAÂ“. Oh wait, thatÂ’s not four digits.
LesseeÂ… Scheduled departure time of the flight SQ221 was 2040hrs. It was retimed to 0015hrs. The scheduled arrival in Sydney was 0715hrs, but the retimed arrival, 0850hrs.
OK, now go buy those numbers. You read it here first. Win first prize better thank me!
For expediency at most US airports, engine startup is initiated while the aircraft is being pushed back. This allows the taxi to commence once the towbar is disconnected.Originally posted by elektra:unfortunately the airplanes do not have a key to turn on the engine
there is an airtug to push back the airplane, then tow it forward slightly. then the airplane can start engine, and proceed itself to the runway.
Thus far, I've only seen the DC-9/MD-8X series perform powerbacks from the gate. A good friend of mine who flies for NWA mentioned that this was permitted due to the high mounting location of the engines which reduces the possibility of debris being sucked into the engines when the thrust reverser buckets are deployed during the powerback.Originally posted by leewan:It's possible for a turbofan to start and reverse out of the gate using thrust reversers although it's strongly not recommended bcos of possible engine damage and ground damage.
It also happens in SIN, but only for smaller a/c like B737 and A320 as their engine thrust won't overpower the airtug. It definitely won't happen wif the B777 even in US as they autostart both engines at the same time and the idle thrust can overpower the airtug resulting in towbar shear. Has happened in SIN b4.Originally posted by Meia Gisborn:For expediency at most US airports, engine startup is initiated while the aircraft is being pushed back.

Sometimes a tug isn't even needed: under certain conditions, Northwest's DC9s are allowed to "power back" from the gate using reverse thrust. I've been on a few domestic flights where this has happened.
