✍️ Sample SPC Questions & Answers
1. What is the purpose of the 'base leg' in the traffic pattern?
The base leg is flown perpendicular to the runway and allows the pilot to judge the turn to final and configure the aircraft for landing.
2. What is the definition of 'Vx' and when would a student pilot use it?
Vx is best angle of climb speed and provides the greatest altitude gain over the shortest horizontal distance, useful for clearing obstacles.
3. According to 14 CFR Part 91, a pilot is prohibited from acting as a crewmember of a civil aircraft within how many hours of consuming any alcoholic beverage?
14 CFR § 91.17 states that no person may act as a crewmember of a civil aircraft within 8 hours after the consumption of any alcoholic beverage. The regulation also prohibits flying with a blood alcohol concentration of 0.04% or greater or while under the influence of alcohol.
4. Which airspace requires a Mode C transponder at all times?
Class B airspace requires an operating Mode C (altitude encoding) transponder for all aircraft operations.
5. Which type of fog forms when warm, moist air moves over a cooler surface?
Advection fog forms when warm moist air moves horizontally over a cooler surface, cooling the air to its dew point — common along coastlines and in spring over cold land.
6. What is the best action if a student pilot becomes lost during a solo cross-country flight?
Climbing improves radio and navigation reception while increasing visibility of landmarks; ATC radar can often provide position identification.
