How much jet fuel does an A320 use?
A 150-seat A320 burns 11,608 kg (25,591 lb) of jet fuel over 3,984 km (2,151 nmi) (between Los Angeles and New York City), or 2.43 L/100 km (97 mpg‑US) per seat with a 0.8 kg/L fuel. Its wing is long and thin, offering better aerodynamic efficiency because of the higher aspect ratio than the competing 737 and MD-80.
What does Flex mean in Airbus?
Flex temp
From Wikipedia, the free encyclopedia. Flex temp is a technique used to produce cost savings through increased engine life and reduced overhaul and fuel costs for airliners by allowing them to take-off at less than rated thrust. For Airbus and Fokker aircraft the technique is known as flex temp or just flex.
When to use flex or toga for takeoff?
“FLEX” is the standard takeoff thrust setting used on Airbus aircraft, unless departing a contaminated (wet / icy) runway or if performance constraints (short runway or hot and high) exist, in which case TOGA (full thrust) is used. “FLEX” takeoff settings use an assumed temperature thrust reduction…
Why is the flex temperature used for takeoff?
The assumed FLEX temperature used (e.g. 40 degrees C) reflects the thrust which would be achieved from a TOGA takeoff with that outside air temperature (+40 C in that example). As the photo shows, the FLEX setting (thrust reduction) results in more runway used on takeoff than TOGA. I used to love the smell of Jet-A in the morning…
When is it Wierd to use Flex take off?
There are several restrictions to its use, but we usually reduce about 8%. It can be wierd when your takeoff thrust is less then the climb thrust needed to make a departure. You take off, and then add power as you climb out. Saves lots of wear and tear on the engines.
What does Flex take off mean on an Airbus?
I don’t know the Airbus’ use of the term, but the F-100, MD80, MD90, DC10, and some Boeing aircraft use the term to mean the “programmed takeoff or go-around thrust” setting.
