Airspace and Weather Minimums Flashcards

(Refer to Figure 25, area 4.) The floor of Class B airspace overlying Hicks Airport (T67) north-northwest of Fort Worth Meacham Field is

Answer: 4,000 feet MSL.

Referring to Figure 25, area 4, Hicks Airport (T67) is located under a shelf of Class B airspace. The numbers associated with the solid blue lines indicate the ceiling and floor of the Class B airspace in hundreds of feet MSL. The segment directly above Hicks Airport shows '110/40', meaning the Class B airspace extends from 4,000 feet MSL up to 11,000 feet MSL. Therefore, the floor of the Class B airspace overlying Hicks is 4,000 feet MSL.

In which type of airspace are VFR flights prohibited?

Answer: Class A.

Class A airspace extends from 18,000 feet MSL up to and including FL600 (60,000 feet MSL) over the contiguous United States and Alaska. All operations within Class A airspace must be conducted under Instrument Flight Rules (IFR), meaning VFR flights are strictly prohibited. This ensures a high level of control and separation for high-altitude air traffic.

(Refer to Figure 26, area 2.) The day VFR visibility and cloud clearance requirements to operate over the town of Cooperstown, after departing and climbing out of the Cooperstown Airport at or below 700 feet AGL are

Answer: 1 mile and clear of clouds.

The town of Cooperstown and its airport (area 2 on Figure 26) are located in Class G airspace from the surface up to 700 feet AGL, as indicated by the magenta vignette. For VFR operations in Class G airspace during the day, below 1,200 feet AGL, the minimum weather requirements are 1 statute mile visibility and remaining clear of clouds. This allows for basic visual flight in uncontrolled airspace.

(Refer to Figure 20, area 1.) What minimum radio equipment is required to land and take off at Norfolk International?

Answer: Mode C transponder and two-way radio.

To operate within Class C airspace, such as that surrounding Norfolk International (KORF) as depicted in Figure 20, area 1, an aircraft must be equipped with an operating two-way radio capable of communicating with ATC and an operating Mode C transponder. The Mode C transponder provides automatic altitude reporting, which is crucial for ATC to maintain separation in this controlled airspace. These requirements ensure proper communication and identification for safety.

Which initial action should a pilot take prior to entering Class C airspace?

Answer: Contact approach control on the appropriate frequency.

Before entering Class C airspace, a pilot must establish two-way radio communication with the Air Traffic Control (ATC) facility providing services for that airspace, typically Approach Control. The pilot must hear their aircraft callsign acknowledged by ATC, signifying that communication has been established, before entering the airspace. This ensures ATC is aware of the aircraft and can provide traffic advisories and separation.

A special VFR clearance authorizes the pilot of an aircraft to operate VFR while within Class D airspace when the visibility is

Answer: at least 1 mile and the aircraft can remain clear of clouds.

A Special VFR (SVFR) clearance allows a pilot to operate VFR within the surface areas of Class B, C, D, or E airspace when weather conditions are below the basic VFR minimums. For an SVFR clearance to be issued, the flight visibility must be at least 1 statute mile, and the aircraft must be able to remain clear of clouds. This provides a limited exception for VFR operations in marginal weather conditions, primarily for landing or departing.

(Refer to Figure 22, area 1.) The visibility and cloud clearance requirements to operate over Sandpoint Airport at night at less than 700 feet AGL are

Answer: 3 miles and 1,000 feet above, 500 feet below, and 2,000 feet horizontally from each cloud.

Sandpoint Airport (area 1 on Figure 22) is located in Class G airspace from the surface up to 700 feet AGL, as indicated by the magenta shading. For VFR operations in Class G airspace at night, below 10,000 feet MSL, the minimum weather requirements are 3 statute miles visibility and cloud clearances of 1,000 feet above, 500 feet below, and 2,000 feet horizontally from clouds. This is a more restrictive requirement than daytime Class G to account for reduced visibility at night.

The basic VFR minimum visibility at night for Class G, E, D, and C airspace below 10,000 feet MSL is 3 statute miles. An exception to that minimum is when below 1,200 feet above the surface and the visibility is at least 1 but less than 3 statute miles

Answer: in Class G airspace clear of clouds when operating in an airport traffic pattern within 1/2 mile of the runway.

While the basic VFR minimum visibility at night for Class G airspace below 10,000 feet MSL is 3 statute miles, there's an exception for local operations. Pilots may operate with at least 1 statute mile visibility and clear of clouds when operating in the airport traffic pattern within 1/2 mile of the runway in Class G airspace. This exception facilitates local airport operations under specific conditions where maintaining visual contact with the airport is paramount.

(Refer to Figure 25, area 4.) The airspace directly overlying Fort Worth Meacham is

Answer: Class D airspace to 3,200 feet MSL.

Fort Worth Meacham Field (FTW) is surrounded by a blue segmented circle on the sectional chart (Figure 25, area 4), which denotes Class D airspace. The number within the segmented circle, '32', indicates the ceiling of this Class D airspace is 3,200 feet MSL. Class D airspace typically extends from the surface up to this specified altitude, requiring two-way radio communication for entry.

(Refer to Figure 26, area 5.) The airspace overlying and within 5 miles of Barnes County Airport is

Answer: Class G airspace from the surface to 700 feet AGL.

Barnes County Airport (area 5 on Figure 26) is depicted without a blue segmented circle or a magenta dashed line, indicating it does not have Class D or Class E airspace extending to the surface. The magenta shading nearby signifies that Class E airspace begins at 700 feet AGL. Therefore, the airspace overlying and within 5 miles of Barnes County Airport from the surface up to 700 feet AGL is Class G airspace, which is uncontrolled.

Under what condition may an aircraft operate from a satellite airport within Class C airspace?

Answer: The pilot must contact ATC as soon as practicable after takeoff.

When departing from a satellite airport within Class C airspace that does not have an operating control tower, the pilot must establish two-way radio communication with the primary Class C airport's Air Traffic Control (ATC) as soon as practicable after takeoff. This ensures ATC is aware of the aircraft's presence and can provide appropriate services and separation within the controlled airspace. This is a critical safety procedure for integrating into controlled traffic.

(Refer to Figure 22.) What are the visibility and cloud clearance requirements in an airplane at night when conducting takeoffs and landings at Shoshone County Airport (Area 3) if the pattern altitude is 1,000 feet AGL?

Answer: 1 SM visibility and clear of clouds if remaining within one-half mile of the airport.

Shoshone County Airport (area 3 on Figure 22) is located in Class G airspace from the surface up to 700 feet AGL. For VFR operations at night in Class G airspace, an exception allows for 1 statute mile visibility and clear of clouds, provided the aircraft remains within one-half mile of the airport and within the airport traffic pattern. This specific exception is designed for local operations near the airport under reduced visibility conditions.

The lateral dimensions of Class D airspace are based on

Answer: the instrument procedures for which the controlled airspace is established.

The lateral dimensions of Class D airspace are not fixed at a specific radius but are individually tailored to contain the instrument procedures (such as instrument approaches and departures) for which the controlled airspace is established. This ensures that aircraft operating under instrument flight rules are within controlled airspace during critical phases of flight, providing a safe and efficient environment for instrument operations.

With certain exceptions, all aircraft within 30 miles of a Class B primary airport from the surface upward to 10,000 feet MSL must be equipped with

Answer: an operable transponder having either Mode S or 4096-code capability with Mode C automatic altitude reporting capability.

With certain exceptions, all aircraft operating within 30 nautical miles of a Class B primary airport, from the surface up to 10,000 feet MSL (the 'Mode C veil'), must be equipped with an operable transponder having Mode C automatic altitude reporting capability. This requirement ensures that ATC can identify and track aircraft, and monitor their altitudes, for safe separation in busy Class B airspace. This enhances safety by providing ATC with crucial traffic information.

(Refer to Figure 20 area 4.) What hazards to aircraft may exist in restricted areas such as R-5302B?

Answer: Unusual, often invisible, hazards such as aerial gunnery or guided missiles.

Restricted areas, such as R-5302B (Figure 20, area 4), denote airspace where operations are subject to restrictions due to the existence of unusual, often invisible, hazards to aircraft. These hazards can include artillery firing, aerial gunnery, or guided missile activities. Pilots must obtain authorization from the controlling agency before entering a Restricted Area to avoid potential danger.

The minimum flight visibility required for VFR flights above 10,000 feet MSL and more than 1,200 feet AGL in controlled airspace is

Answer: 5 miles.

For VFR flights in controlled airspace above 10,000 feet MSL and more than 1,200 feet AGL, the minimum flight visibility required is 5 statute miles. This increased visibility requirement, along with cloud clearances of 1,000 feet below, 1,000 feet above, and 1 statute mile horizontally, ensures greater safety margins at higher altitudes where aircraft speeds are typically faster and reaction times are reduced.

(Refer to Figure 26, area 3.) When flying over Arrowwood National Wildlife Refuge, a pilot should fly no lower than

Answer: 2,000 feet AGL.

Pilots are requested to operate aircraft at a minimum altitude of 2,000 feet AGL over National Wildlife Refuges, Parks, and Forest Service areas, such as the Arrowwood National Wildlife Refuge (Figure 26, area 3). This is a recommended operating practice, not a regulation, to minimize disturbance to wildlife and preserve the natural environment. Adhering to this practice helps protect sensitive ecosystems.

The vertical limit of Class C airspace above the primary airport is normally

Answer: 4,000 feet AGL.

The vertical limit of Class C airspace above the primary airport is normally 4,000 feet AGL. This airspace typically consists of two concentric circles: an inner circle extending from the surface to 4,000 feet AGL, and an outer circle (shelf area) extending from 1,200 feet AGL to 4,000 feet AGL. This structure provides controlled airspace for arriving and departing aircraft.

(Refer to Figure 26, area 1.) Identify the airspace over Tomlinson Airport (8J7).

Answer: Class G airspace - surface up to but not including 1,200 feet AGL, Class E airspace - 1,200 feet AGL up to but not including 18,000 feet MSL.

Tomlinson Airport (8J7) (area 1 on Figure 26) is located in an area without any magenta or blue shading, which indicates that Class E airspace begins at 1,200 feet AGL. Therefore, the airspace from the surface up to but not including 1,200 feet AGL is Class G airspace (uncontrolled), and from 1,200 feet AGL up to but not including 18,000 feet MSL is Class E airspace (controlled). This is a common configuration for airports not associated with a control tower.

What minimum pilot certification is required for operation within Class B airspace?

Answer: Private Pilot Certificate or Student Pilot Certificate with appropriate logbook endorsements.

To operate an aircraft within Class B airspace, a pilot must hold at least a Private Pilot Certificate. However, a Student Pilot Certificate holder may also operate in Class B airspace if they have received specific ground and flight training and possess the appropriate logbook endorsements from an authorized instructor. This ensures pilots have the necessary knowledge and skill to operate in complex, high-traffic airspace.
