Perfomance L4

Induced drag is proportional to:

• v^2

• rho

• 1/v^2

• v^2 and rho

At which point does parasite drag becomes bigger than induced drag?

Which are the axis of the total, induced and parasite drag in the graph:

• Drag and TAS

• Lift and TAS

• Drag and CAS

• Drag and EAS

A higher Mach in level flight requires:

• Decrease alpha

• Higher effective airflow

• Increase AoA

• Decrease effective airflow

If you are climbing at constant TAS

• Mach is constant

• Mach increases

• IAS increases

• Mach decreases

With 30º bank angle the load factor will be:

Icing could be found

• even in clear air

• inside of the tanks

• on cakes or pastries.
• in the upper part of a flap

The power required will

• Increase with increase in altitude

• Decrease with increase in altitude

• Increase with decrease in altitude

• Increase with decrease in density altitude

In a coventional airfoil which is the critical alpha

• The critical alpha for a conventional airfoil is typically 90 degrees.

• The critical alpha for a conventional airfoil is typically 5 degrees.

• The critical alpha for a conventional airfoil is typically 15 degrees.

• The critical alpha for a conventional airfoil is typically 30 degrees.

Icing appear first

• at the trailing edge

• at the leading edge of the flaps

• around the window

• at the root of the blade in a propeller
