CGI Airport Operations & Airspace 1 — Questions and Answers
Question 1: What is the standard traffic pattern altitude for turbine-powered aircraft at an uncontrolled airport?
- 500 feet AGL
- 800 feet AGL
- 1,500 feet AGL (Correct answer)
- 2,000 feet AGL
Correct answer: 1,500 feet AGL
Turbine-powered aircraft typically fly a traffic pattern at 1,500 feet AGL, compared to the 1,000-foot AGL standard for piston aircraft.
Question 2: At a non-towered airport, which direction should the traffic pattern be flown unless otherwise indicated?
- Right-hand traffic
- Left-hand traffic (Correct answer)
- Either direction based on wind
- Straight-in approaches only
Correct answer: Left-hand traffic
At non-towered airports, the standard traffic pattern is left-hand traffic unless right-hand traffic is specifically designated by airport markings or the Chart Supplement.
Question 3: What does a flashing green light signal from the control tower mean to an aircraft in flight?
- Cleared to land
- Return for landing (Correct answer)
- Give way to other aircraft and continue circling
- Airport unsafe—do not land
Correct answer: Return for landing
A flashing green light signal to an aircraft in flight means cleared to return for landing.
Question 4: What type of airspace surrounds the nation's busiest airports and requires an ATC clearance and an operable transponder?
- Class C airspace
- Class B airspace (Correct answer)
- Class D airspace
- Class E airspace
Correct answer: Class B airspace
Class B airspace surrounds the nation's busiest airports and requires an ATC clearance, an operable Mode C transponder, and adherence to assigned speeds and routes.
Question 5: What equipment is required to operate within Class C airspace?
- Two-way radio only
- Two-way radio, Mode C transponder (Correct answer)
- Two-way radio, Mode C transponder, and DME
- Two-way radio, TCAS, and Mode S transponder
Correct answer: Two-way radio, Mode C transponder
Class C airspace requires an operable two-way radio and a Mode C altitude-encoding transponder to allow ATC radar identification.
Question 6: What does a segmented circle at an uncontrolled airport indicate?
- The location of fuel services
- The direction of landing and traffic pattern information including runway layout and pattern direction (Correct answer)
- A displaced threshold
- A closed runway
Correct answer: The direction of landing and traffic pattern information including runway layout and pattern direction
The segmented circle system provides landing direction, traffic pattern direction, and other airport information visible from the air and ground.
