CTO CTO Noise Abatement & Special Use Airspace Procedures 1 — Questions and Answers
Question 1: What is the primary purpose of a Noise Abatement Departure Procedure (NADP) published in a terminal instrument procedure?
- To increase runway capacity during peak hours
- To reduce aircraft noise impact on communities near the airport (Correct answer)
- To improve fuel efficiency for all departures
- To sequence departures with arrivals more efficiently
Correct answer: To reduce aircraft noise impact on communities near the airport
NADPs are designed to minimize noise exposure over populated areas near airports by prescribing specific climb and power reduction profiles.
Question 2: A Prohibited Area (P) on a sectional chart means that flight within that airspace is:
- Allowed with prior ATC permission
- Restricted to IFR flights only
- Not permitted at any time under any circumstances (Correct answer)
- Allowed only during daylight hours
Correct answer: Not permitted at any time under any circumstances
Prohibited Areas are established for security or national welfare reasons, and flight within them is not permitted under any circumstances.
Question 3: A Restricted Area (R) on an aeronautical chart indicates airspace where flight is:
- Completely prohibited to all aircraft
- Subject to restrictions due to hazardous activities but may be available when not in use (Correct answer)
- Available only to military aircraft at all times
- Open to civil aircraft during instrument meteorological conditions
Correct answer: Subject to restrictions due to hazardous activities but may be available when not in use
Restricted Areas contain hazardous activities such as artillery firing or aerial gunnery, but may be released to ATC for non-military use when not active.
Question 4: A Military Operations Area (MOA) requires VFR pilots to exercise extreme caution. Tower controllers should advise departing VFR aircraft of an active MOA by:
- Denying departure clearance until the MOA closes
- Issuing the advisory 'CAUTION, [MOA name] MOA IS ACTIVE' (Correct answer)
- Requiring aircraft to file IFR flight plans
- Contacting ARTCC before issuing departure clearance
Correct answer: Issuing the advisory 'CAUTION, [MOA name] MOA IS ACTIVE'
Controllers should advise pilots about active MOAs that may affect their flight path so pilots can make informed decisions about routing.
Question 5: Temporary Flight Restrictions (TFRs) are established under which FAR parts for events such as Presidential movements?
- FAR Part 71 and 73
- FAR Part 91.137, 91.138, 91.139, and 91.141 (Correct answer)
- FAR Part 93 and 95
- FAR Part 61 and 67
Correct answer: FAR Part 91.137, 91.138, 91.139, and 91.141
TFRs are established under FAR Part 91 sections 137–141, covering disaster/hazard areas, VIP movements, and national defense needs.
Question 6: When a TFR is active at or near an airport, what is the tower controller's primary responsibility regarding departing VFR traffic?
- Deny all VFR departures until the TFR lifts
- Issue appropriate advisories and ensure pilots are aware of the TFR boundaries (Correct answer)
- Automatically reroute all departures around the TFR via radar vectors
- Contact the pilot's destination airport to file a NOTAM
Correct answer: Issue appropriate advisories and ensure pilots are aware of the TFR boundaries
Controllers must inform departing pilots of active TFRs that could affect their flight path and issue advisories to help pilots avoid airspace violations.
