B two quick, white flashes between green flashes.
To set the high intensity runway lights on medium intensity, the pilot should click the microphone seven times, and then click it
5x within 5 sec
The arrows that appear on the end of the north/south runway indicate that the area
cannot be used for landing, but may be used for taxiing and takeoff.
A slightly high glide slope indication from a precision approach path indicator is
3 white lights and 1 red light.
Wingtip vortices created by large aircraft tend to
sink below the aircraft generating turbulence.
The wind condition that requires maximum caution when avoiding wake turbulence on landing is a
light, quartering tailwind.
How does the wake turbulence vortex circulate around each wingtip?
Outward, upward, and around each tip.
During a night flight, you observe a steady white light and a flashing red light ahead and at the same altitude. What is the general direction of movement of the other aircraft?
The other aircraft is flying away from you.
Eye movements during daytime collision avoidance scanning should
not exceed 10 degrees and view each sector at least 1 second.
It is the responsibility of the pilot and crew to report a near midair collision as a result of proximity of at least
500 feet or less to another aircraft.
Any airspace that requires the use of a transponder also requires aircraft to be
equipped with specific ADS-B Out equipment.
When should ADS-B equipment be operated on the ground while taxiing?
All the time when on airport surface
Absence of the sky condition and visibility on an ATIS broadcast indicates that
C the ceiling is at least 5,000 feet and visibility is 5 miles or more.
Unless otherwise authorized, two-way radio communications with Air Traffic Control are required for landings or takeoffs at all towered airports
regardless of weather conditions
In which type of airspace are VFR flights prohibited?
Class A
The minimum distance from clouds required for VFR operations on an airway below 10,000 feet MSL is
500 feet below, 1,000 feet above, and 2,000 feet horizontally.
If Air Traffic Control advises that radar service is terminated when the pilot is departing Class C airspace, the transponder should be set to code
1200
If Air Traffic Control advises that radar service is terminated when the pilot is departing Class C airspace, the transponder should be set to code
1200

The pilot must contact ATC as soon as practicable after takeoff.
The vertical limit of Class C airspace above the primary airport is normally
4,000 feet AGL.
For VFR flight operations above 10,000 feet MSL and more than 1,200 feet AGL, the minimum horizontal distance from clouds required is
1 mile
How can you determine if another aircraft is on a collision course with your aircraft?
There will be no apparent relative motion between your aircraft and the other aircraft.

1 mile
What are the minimum requirements for airplane operations under special VFR in Class D airspace at night?
The pilot must be instrument rated, and the airplane must be IFR equipped.
The lateral dimensions of Class D airspace are based on
the instrument procedures for which the controlled airspace is established.
When turning onto a taxiway from another taxiway, what is the purpose of the taxiway directional sign?
Indicates designation and direction of taxiway leading out of an intersection.
A special VFR clearance authorizes the pilot of an aircraft to operate VFR while within Class D airspace when the visibility is
at least 1 mile and the aircraft can remain clear of clouds.
When activated, an emergency locator transmitter (ELT) transmits on
406 MHz.
Normal VFR operations in Class D airspace with an operating control tower require the visibility and ceiling to be at least
1,000 feet and 3 miles.

1 mile
Your VFR flight will be conducted above 10,000 ft. MSL in Class E airspace. What is the minimum flight visibility?
5 SM
The Aeronautical Information Manual (AIM) specifically encourages pilots to turn on their landing lights when operating below 10,000 feet, day or night, and especially when operating
in conditions of reduced visibility.
From whom should a departing VFR aircraft request radar traffic information during ground operations?
Ground control, on initial contact.
While on final approach for landing, an alternating green and red light followed by a flashing red light is received from the control tower. Under these circumstances, the pilot should
exercise extreme caution and abandon the approach, realizing the airport is unsafe for landing.
The correct method of stating 10,500 feet MSL to ATC is
“ONE ZERO THOUSAND, FIVE HUNDRED.”
A non-tower satellite airport, within the same Class D airspace as that designated for the primary airport, requires radio communications be established and maintained with the
primary airport’s control tower.
Which light signal from the control tower clears a pilot to taxi?
Flashing green
TRSA Service in the terminal radar program provides
sequencing and separation for participating VFR aircraft.
The greatest vortex strength occurs when the generating aircraft is
heavy, clean, and slow.
What is the purpose of the runway/runway hold position sign?
Denotes intersecting runways.
The numbers 9 and 27 on a runway indicate that the runway is oriented approximately
090° and 270° magnetic.
