Question 1

What causes a sonic boom?

Accepted Answer

Shock waves produced when an aircraft exceeds the speed of sound

Answer

A sonic boom is caused by the pressure shock waves that form and radiate outward when an aircraft accelerates beyond Mach 1, the speed of sound.

Question 2

What is the approximate speed of sound at sea level under standard atmospheric conditions?

Accepted Answer

1,235 km/h

Answer

The speed of sound at sea level under standard conditions (15°C) is approximately 1,235 km/h (343 m/s or 767 mph), which equals Mach 1.

Question 3

What is an airfoil?

Accepted Answer

The cross-sectional shape of a wing designed to generate aerodynamic lift

Answer

An airfoil is the cross-sectional shape of a wing, curved on top and flatter below, which causes differential airflow speeds that generate lift.

Question 4

What does ATC stand for in aviation?

Accepted Answer

Air Traffic Control

Answer

ATC stands for Air Traffic Control, the ground-based service responsible for directing aircraft movement to ensure safe, orderly, and efficient flow in controlled airspace.

Question 5

What is the International Standard Atmosphere (ISA) temperature at sea level?

Accepted Answer

15°C (59°F)

Answer

The International Standard Atmosphere defines sea-level temperature as 15°C (59°F), serving as the universal reference for aviation performance calculations and aircraft certification.
