OM = DOM + crew and fuel

Swept wings have:

• Poor lift qualities

• Higher stall speeds

• Speed instability at low speeds

• A wing-tip stalling tendency

Always make sure to update yourself with the latest information on these type of questions.

CFM56-7 series with a max takeoff thrust of 27,300lb.

These engines have higher thrust, improved efficiency, and lower maintenance costs than its predecessor, the CFM56-3 series.

180 minutes extended range (ETOPS).

Bypass ratio 5.5:1

Frequency range from 200-1750kHz, medium and low range frequency bands.

To protect the engine from blowing up as it is easy to open the throttles to far during take off at sea level.

Their formation is most often triggered by freezing water vapour from the exhaust of aircraft engines.

Wingtip vortices are tubes of circulating air that are left behind a wing as it generates lift.

They are caused by the difference in pressure above and below the wing causing the air to 'escape' from the high pressure area below the wing to the low pressure area above the wing, by rolling around the tip of the wing. This creates a vortex that trails behind the wing.

Contingency fuel is carried to account for additional enroute fuel consumption caused by wind, routing changes or ATM: ATM/CNS restrictions.

They are aerodynamically efficient surfaces located at the wing tips, designed to reduce induced drag and increase fuel efficiency.

They increase efficiency by reducing the size of the wingtip vortices, which are created by the difference between the pressure on the upper surface of the wing and that on the lower surface.

For every 1kg of air passing through the combustion chamber, 11kg of air pass bypass the combustion chamber.
