anyone interested to catch AirForce One when Obama arrives here in Nov for the APEC CEO Summit?
Awesome compilation of aviation photos.Made my day as an aircraft photography enthusiast.

Changi Air Base (West) in the background, the race will probably be conducted on RWY 20R and taxiway Whisky Papa.
Hmm, these question seems awfully familiar... :think:Any idea what's the takeoff weight of the 747 and the thrust of the engines on that day (temperature), is the thrust to weight ratio higher than the Porsche 911? What variables are important? Wonder which will be faster.
225.90 km/hr rotation speed in a 800 meters takeoff roll and a duration of approximately 6 to 8 seconds and this is for a B744, Jett8 B747-281F/SCD (9V-JEB "Shogun") might just take little longer with its older GE CF6-50E2 engines.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)
Was just having a chat with a pilot from ANA and this is what he defined CAAS as, "Committee Against Aviation in Singapore". :bsmilie:

Somebody thinking the same way I guess.
According to Wikipedia, the Porsche 911 GT3 will take 13 seconds to cover 400 meters and reach 190 km/h.

I'll be there, the last time I was there 2 years ago there was also quite a significant amount of Singaporean visitors.Anybody going to Lima2009?

LIMA 2009 will be held at the Mahsuri International Exhibition Centre (MIEC) just right next to Langkawi International Airport.Is the exhibition grounds near the airport?
