Boldmethod

Good luck!


  1. 1) Your friend asks you what 'angle of incidence' is. You answer:

    It's the angle between the wing's chord line and the aircraft's longitudinal axis.

    It's the angle between the wing's chord line and the aircraft's longitudinal axis.

  3. 3) You're sitting on the ramp, your altimeter is set to 29.67" Hg, and it reads 1000 feet. You pick up ATIS, and the latest altimeter setting is 30.17. You enter the new setting on your altimeter. What elevation does it read now?

    Since you've increased the altimeter by .5 inches Hg, your indicated altitude will increase by 500 feet, and it will read 1,500'.

  4. 4) You're climbing at 90 knots through an icing layer. Your pitot heat fails, and the pitot tube completely ices over, though your static ports remain open. If you continue climbing at 90 knots indicated, your aircraft will be flying:

    The trapped static pressure in the pitot tube is now greater than the actual static pressure, and your airspeed indicator starts to speed up. You're now flying slower than indicated. The opposite happens if you descend.

  5. 5) What type of flap increases the wing's area when it is extended?

    Fowler flaps increase the area of your wing by extending out on rails or tracks. Fowler flaps often have a series of slots to add energy to the airflow as well - they're called slotted-Fowler flaps.

Ready to start your flight training?

In the American Airlines Cadet Academy, you'll train with select flight schools and be paired with an American Airlines pilot mentor to walk with you through the program. Accepted flight school candidates will have the option to work with Discover® Student Loans to apply for a loan.

After you complete the program, AA's three wholly owned regional carriers (Envoy, PSA, and Piedmont) will offer you a guaranteed interview. If you're hired by one of these regional airlines, you will be well on your way to working at American Airlines.
