CTO Airspace Structure & Regulations 4 — Questions and Answers
Question 1: A pilot contacts the tower and says 'unable to comply' with a Class D entry instruction. What is the correct tower controller response?
- Issue an immediate clearance to land
- Provide an alternative instruction or deny entry (Correct answer)
- Declare ATC emergency on behalf of the aircraft
- Transfer the aircraft to approach control immediately
Correct answer: Provide an alternative instruction or deny entry
When a pilot is unable to comply, the controller must issue an alternative clearance or instruct the aircraft to remain clear of the airspace.
Question 2: Military Operations Areas (MOAs) are depicted on sectional charts with what color boundary?
- Blue
- Red
- Magenta
- Teal/Cyan (Correct answer)
Correct answer: Teal/Cyan
MOAs are depicted on aeronautical charts with magenta dashed boundary lines and are labeled with the MOA name.
Question 3: What is the lateral dimension of the inner ring of standard Class C airspace?
- 5 NM radius (Correct answer)
- 10 NM radius
- 15 NM radius
- 20 NM radius
Correct answer: 5 NM radius
The inner ring of Class C airspace typically extends from the surface to 4,000 feet AGL within a 5 NM radius of the primary airport.
Question 4: A Restricted Area is 'hot' (active). What does this mean for a non-participating aircraft?
- The aircraft may transit if above 10,000 feet
- The aircraft must obtain a waiver from the FAA to enter
- Entry is prohibited or requires ATC authorization (Correct answer)
- The aircraft may enter if operating VFR
Correct answer: Entry is prohibited or requires ATC authorization
When a Restricted Area is active, entry is prohibited or requires specific authorization from the controlling agency due to hazardous activities.
Question 5: Victor airways (VOR Federal Airways) are defined as extending from 1,200 feet AGL to what upper limit?
- 10,000 feet MSL
- 12,500 feet MSL
- 17,999 feet MSL (Correct answer)
- 18,000 feet MSL
Correct answer: 17,999 feet MSL
Victor airways extend from 1,200 feet AGL up to but not including 18,000 feet MSL, where Class A airspace and Jet routes begin.
Question 6: Under what regulation must a pilot report immediately upon landing if they deviated from an ATC clearance due to an emergency?
- FAR 91.3
- FAR 91.123 (Correct answer)
- FAR 91.183
- FAR 91.139
Correct answer: FAR 91.123
FAR 91.123 requires a pilot who deviates from an ATC clearance under emergency authority to notify ATC as soon as possible and submit a report upon ATC request.
Question 7: What is the standard width of a Victor airway (Federal Airway) on each side of the airway centerline?
- 2 NM
- 4 NM
- 8 NM (Correct answer)
- 10 NM
Correct answer: 8 NM
Victor airways are 8 nautical miles wide — 4 NM on each side of the VOR radial that defines the airway centerline.
