anhedral is the downward inclinitation of the wing from the root to the tip.

Meridians converge from their maximum distance apart (at the equator) to the poles where they meet.

Great circles are the shortest distance between two points and convergency represents the change in direction experienced between those points.

Fuel injection provides:

• Fuel free from vaporization ice

• Better economy through metered delivery

• More responsive and efficient engine

• Less maintenance

Jet engines are designed to achieve their best specific fuel consumption at high rpm, which can only be achieved at high altitudes where the air density is low.

Thrust produced will be low enough to equal the required cruising thrust. Also high altitude gives the best operating conditions for the airframe i.e. minimum drag during the cruise.

Turboprops need relatively dense air for the propellers to work efficiently and at high altitude the density would be too low.

Battery power to the starter motors.

Alternate air is....

Occurs at absolute ceiling where low speed buffet and high speed (Mach) buffet are coincident.

When reaching the coffin corner, both increasing and decreasing the corner speed will result in a loss of control (either the aircraft stalls, or mach buffeting starts).

Assuming I'm performing single pilot operations:

• power idle,

• max brakes (and reversers if available),

-maintain directional control using rudder input,

• After coming to a full stop set parking break.

• Inform ATC 'Stopping'.

• Initiate the appropriate process to diagnose the problem (ECAM, NITS DODAR, checklists....).

• When performing multi pilot operations the actions performed by me will depend with my current role: PF, PM and/or CM1 CM2.

-15°C

because:

-2°C per 1000 feet gives -30°C.

ISA: 15°C at sea level - 30°C = -15°C at FL150

Aircraft categories are based on Vat (in knots):

A <91

B 91-120

C 121-140

D 141-165

E 166 - 210
