Airspace & VFR Weather Minimums

Correct

The answer is A: Not allowed; all Class A flight must be conducted under IFR

FL210 is in Class A, where 14 CFR 91.135 requires every operation to be conducted under IFR with an ATC clearance. The 91.155 table lists VFR minimums for Class A as 'not applicable' because VFR flight is not permitted there.

Correct

The answer is B: 4,500 feet MSL

ATC can assign VFR altitudes that do not conform to 14 CFR 91.159 for separation, and "resume appropriate VFR altitudes" means you must return to one that does. On a westbound magnetic course (180 through 359 degrees) that is an even thousand plus 500 feet, so 4,500 feet MSL. The altitude ATC assigned inside Class B no longer applies, and an odd thousand plus 500 (such as 3,500) is for eastbound courses.

Correct

The answer is A: Participation is voluntary; you may ask to terminate the service

Pilot participation in the outer area is voluntary and can be discontinued at the pilot's request; Class C services are provided there unless the pilot requests termination. No clearance is needed, and the outer area is not Class C airspace.

Correct

The answer is C: "N8822Q, standby."

Two-way communication is established when the controller responds using your call sign, so "N8822Q, standby" allows entry. A reply without your call sign does not establish communication, and an explicit instruction to remain outside must be followed.

Correct

The answer is A: from 1,200 feet AGL up to but not including 18,000 feet MSL

Federal airways and low-altitude RNAV routes are Class E airspace that, unless otherwise specified, extend upward from 1,200 ft AGL to, but not including, 18,000 ft MSL, where Class A begins.

Correct

The answer is B: No; the reported ground visibility of 2 SM governs

91.155(d)(1) requires reported ground visibility of at least 3 SM to take off VFR within a surface area. Flight visibility is used only when ground visibility is not reported. With 2 SM reported, you would need a special VFR clearance.

Correct

The answer is A: 5 SM; 1,000 ft below, 1,000 ft above, 1 SM horizontal

In Class G more than 1,200 ft AGL and at or above 10,000 ft MSL, the minimums are 5 SM and 1,000 ft below, 1,000 ft above, and 1 SM horizontal, day or night, the same as Class E at that altitude.

Correct

The answer is A: Other SVFR flights and IFR flights

The AIM states that ATC provides separation between special VFR flights and between these flights and IFR flights. Normal VFR traffic is not separated from SVFR traffic.

Correct

The answer is A: In the special use airspace tabulation in the chart margin

SUA areas are labeled on the chart by type and number, and the tabulation in the chart margin lists altitude, time of use, and the controlling agency or contact facility and frequency. Pilots can contact that agency for the current status.

Correct

The answer is B: Unsafe congestion of sightseeing aircraft over an incident or event

91.137(a)(3) TFRs prevent an unsafe congestion of sightseeing and other aircraft above an incident or event that may generate a high degree of public interest. Space operations fall under 91.143, and the President under 91.141.

Correct

The answer is A: Regular switching on and off of all available lights

ICAO series 5: regular switching on and off of all available lights, in a manner distinct from flashing lights, means 'Cannot comply.' Irregular flashing of all available lights (series 6) means 'In distress.'

On a sectional, prohibited, restricted and warning areas are depicted in blue, while MOAs and alert areas are depicted in magenta. Controlled firing areas are not charted at all.
