What do you mean?

Oops,

sry :X
W0 is total weight of aircraft at take-off aka TOW.
SLO is ground distance used for the aircraft to lift off.

Those units seems awfully familiar but i just couldn't get my head around it. Got it now, thanks.

Gah,

yoo nvr answer my question :X
Any idea wat was the distance used for T/O?
Wat was the Vr anyway?

The exact take-off weight (which BTW is absolutely not known to me) has to be known before the V1/Vr/V2 speed can be calculated.

Anyway I'll hazard a guess with reference to the charts available to me based on a 200,000 kg total take-off weight and under the following operational conditions...

• Altitude region A,
• Flaps 20 with maximum rated thrust,
• Dry and straight runway with wind factor not taken into account.

V1: 90 KIAS
Vr: 105 KIAS (note: see below)
V2: 130 KIAS

As the 105 KIAS rotation speed is below the Vmcg (Minimum Controllable Ground Speed), 122 KIAS in such a situation, the Vmcg figure has to be used in lieu of the calculated Vr figure instead. Therefore the aircraft is only rotated at 122 KIAS and the takeoff roll should not take more than 800 meters (guesstimate).

* KIAS --> (Knots, Indicated Air Speed)

Mmm,

ok .. seems logical haha Sry for troubling yoo with the maths :X
I was doing a question on calculating the SL for B747-400 for landing. A calculation error resulted in the B747 turning into a STOL a/c haha with 13.96m for landing ground roll HAHAH!

Just wondering, does anyone owns an airband scanner? If I would to get one from UK, this is definitely not allowed over here right?

[hengpy]

my first virgin plane spotting trip at changi beach (runway 20C ??)on 24 Aug morning.
stayed there from 0830H to 1010H and got 21 planes in all.
some of my shoots below

Model: Airbus A320-216
Registration: 9M - AFP


Model: ATR 72-212A
Registration: 9M - FYB


Model: F-5E
Registration: B39


Model: Boeing 777-212(ER)
Registration: 9V - SQE


Model: Airbus A330-300
Registration: B - 18311


Hope the TS won't mind me posting (^_^)

Why so leychey one? Who is your lecturers? Perhaps I might know some of them?

Disregarding the maximum true headwind component limitation for a CAT I/II/III autoland, you will definitely be able to land and stop a B744 under 13.96m with the assistance of a magical 150 knots divine headwind .

BTW which SAR-66 modules will you be exempted upon completion of your course? If you truly wish to be a LAE, it's best if you can get into a university and aim for a Category C licence upon graduation, but by the time you have a degree in your hands you might want to consider better prospects in other industry instead.

Airband scanners are classified controlled items by the IDA and you have to apply for a permit to import them (even for personal use). I own a Maycom AR-108, cheap and discreet enough to avoid unwanted attention with a earpiece.

Gah,

Unfortunately, i wanna b a pilot :X
I forgot which r the once dat r exempted .. I'm too busy studying to tink of dat HAHA ..

Wah,

I like his lighting .. Nice ..

Cowz.

In that case you'll have to earn your wings with the RSAF, else you'll have to wait till you're 26 years old (by law) before even being considered for an application as a commercial pilot by the air operators.

Though I admire your aspiration and sincerely wish you the very best.

[hengpy]

some more planes..

[hengpy]

and some more..

[hengpy]

and some more (^_^)

[hengpy]

the last of the 24 Aug shoot =P

[Legoz]

Cool..
Its not everyday that you catch sight of a F5 at changi. =)

By the way, 9V-SQE is a non ER variant.

By the way, 9V-SQE is a non ER variant.

All of SIA B777-212 (even the 9V-SR* and 9V-SQ* registered aircraft) are build as the ER variant by Boeing, though the maximum rated thrust from the RB211 Trent 884 engines are permanently de-rated and restricted by the FADEC. They can be reprogrammed to enable a higher MTOW and longer operating range equivalent to the ER varient, though I'm not aware if SIAEC has ever done such a reprogramming.

Correct, but SQ and SR series are not ER variants by current config. Only the SV series are as the Trent 800 engines are more powerful. Whether SIAEC does that, it's already the hangar side.
