Last Minute Checkup

Question 1

What causes a stall to occur?

Answer 1

• Angle of attack increases, smooth airflow separates over the upper surface of the wing, decreasing lift. Upon reaching the critical angle of attack, the airplane is no longer producing enough lift to continue flying.

An airplane can stall at any airspeed or altitude, but will always stall at the same critical angle of attack

Question 2

Stall speed is affected by?

Answer 2

Weight, load factor, and power

Question 3

What causes an airplane to spin?

Answer 3

An airplane must (1) stall
and be in (2) uncoordinated flight to produce a stall.

An airplane will continue to
spin as long as one wing is producing more lift than the other and the airplane remains in a stall.

Question 4

What is the purpose of flaps?

Answer 4

Lift + Drag.
Allows for steeper approaches without an increase in airspeed. Flaps decrease stall speed as well

Question 5

What are the rules for flying over water? (Part 91)

Answer 5

Flying 50NM or more away from shore (out of power off
glide range) each occupant must be provided with a flotation device (PFD, inflatable raft, etc.)

Question 6

Can you fly through an active MOA?

Answer 6

Flying VFR: Yes, but remain vigilant for fast moving military aircraft, and monitor or request flight following from the controlling agency.

Flying IFR: Restricted for IFR flights when active.

Question 7

When is ADS-B Out required?

Answer 7

• Class E airspace ≥ 10k MSL
• Within 30 NM Mode C veil
• Above and within the lateral boundaries of Class B or Class C airspace
• Class E airspace over the Gulf of Mexico.
• ≥ 3k MSL within 12 nm of the
  U.S. coast

Question 8

What must a commercial pilot do to stay current?

Answer 8

• Current Flight Review
• Carrying passengers: 3 TO/landings in preceding 90 days.
• Carrying passengers at Night: 3 TO/LDG to full stops at night in preceding 90 days (1hr aftersunset to 1hr before sunrise)

Question 9

How long does a 2nd class medical last?

Answer 9

• Commercial privileges -12 months.
• Under 40? 60 Months
• Over 40? 24 Months

Question 10

What are the elements that constitute “Common Carriage”?

Answer 10

1) Holding out/Willingness to take anyone/anything
2) Carrying people or property
3) Transporting from Place A to Place B (ex.-KLVN to KEAU)
4) For Compensation or Hire

Question 11

What are the requirements for supplemental oxygen?

Answer 11

-12,500-14,000ft = If at this altitude for 30min or more, flight crew requires
supplemental O2

-More than 14,000ft-15,000ft = Flight crew requires supplemental O2

-More than 15,000ft = Flight crew requires O2, passengers must be offered/provided O2

Question 12

What causes hypoxia? What are the symptoms? And what is the remedy?

Answer 12

-Causes: Lack of O2 to the brain
-Symptoms: Headache, Euphoria, Visual Impairment, Drowsiness, Lightheaded
-Remedy: Descend to lower altitude

Question 13

What are the different types of Hypoxia?

Answer 13

1) Hypoxic Hypoxia: Too high
2) Hypemic Hypoxia: Blood can’t deliver
3) Histotoxic Hypoxia: Cells can’t use O2
4 Stagnant Hypoxia: GLOC

Question 14

What causes CO poisoning? What are the symptoms, and what are the remedies?

Answer 14

• Causes: CO gases leaking into the cabin area. Most likely a leak inside the
  muffler shroud that travels through the heat vents
  -Symptoms: Headache, Blurred Vision, Drowsiness, Dizziness
  -Remedy: Turn of cabin heat, open outside air vents, crack windows if able

Question 15

How does a constant speed propeller work?

Answer 15

Prop control lever controls the prop governor which changes prop pitch through increase/decrease in oil pressure inside the oil hub.
