B4 FAA WRITTEN Flashcards
Altimeter setting is the value to which the barometric pressure scale of the altimeter is set so the altimeter indicates
true altitude at field elevation.
Preflight action, as required for all flights away from the vicinity of an airport, shall include
alternate course of action if the flight cannot be completed as planned.
The mature stage of a thunderstorm begins with
the start of precipitation.
(Refer to figure 20, area 1.) The NALF Fentress (NFE) Airport is in what type of airspace?
Class E. The Nalf Fentress (NFE) airport is halfway between areas 1 and 2 in Figure 20. It is inside a magenta dashed line indicating Class E airspace starts at the surface.
When activated, an emergency locator transmitter (ELT) transmits on
406 MHz.
Unless otherwise authorized, which situation requires ADS-B?
Overflying Class C airspace below 10,000 feet MSL.
If instructed by ground control to taxi to Runway 9, the pilot may proceed
to the next intersecting runway where further clearance is required.
(Refer to Figure 67.) What effect does a 30-gallon fuel burn have on the weight and balance if the airplane weighed 2,784 pounds and the MOM/100 was 2,222 at takeoff?
Moment will decrease to 2,087 lbs-in.
Unless otherwise authorized, the maximum indicated airspeed at which aircraft may be flown when at or below 2,500 feet AGL and within 4 nautical miles of the primary airport of Class C airspace is
200 kts
With respect to the certification of aircraft, which is a class of aircraft?
Airplane, rotorcraft, glider, balloon. EXPLANATION With respect to the certification of aircraft, class is a broad grouping of aircraft having similar means of propulsion, flight, or landing. Examples include airplane, rotorcraft, glider, balloon, landplane, and seaplane.
What change occurs in the fuel/air mixture when carburetor heat is applied?
The fuel/air mixture becomes richer. EXPLANATION Carburetors are normally calibrated at sea level pressure to meter the correct fuel/air mixture. As altitude increases, air density decreases and the amount of fuel is too great for the amount of air–the mixture is too rich. This same result may be brought about by the application of carburetor heat. The heated air entering the carburetor has less density than unheated air and the fuel/air mixture is enriched.
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. EXPLANATION Controlled airspace above 10,000 feet which allows VFR is Class E airspace, and requires cloud clearance of 1,000 feet below, 1,000 feet above, and 1 SM horizontal during operations above 10,000 feet MSL and more than 1,200 feet AGL.
If the grade of fuel used in an aircraft engine is lower than specified for the engine, it will most likely cause
detonation.
The left turning tendency of an airplane caused by P-factor is the result of the
propeller blade descending on the right, producing more thrust than the ascending blade on the left.
VFR cruising altitude is true or magnetic heading?
magnetic
After takeoff, which airspeed would the pilot use to gain the most altitude in a given period of time?
V(Y). EXPLANATION V(Y) (best rate-of-climb speed) is the calibrated airspeed at which the airplane will obtain the maximum increase in altitude per unit of time (feet per minute) after takeoff.
During the life cycle of a thunderstorm, which stage is characterized predominately by downdrafts?
Dissipating. EXPLANATION Downdrafts characterize the dissipating stage of the thunderstorm cell and the storm dies rapidly.
True altitude is
the vertical distance of an aircraft above mean sea level (MSL)
Indicated altitude
the altitude shown on an aircraft’s altimeter when it is set to the local barometric pressure at the airport
Density Altitude
It is calculated by taking pressure altitude and correcting for non-standard temperature and pressure conditions.
What values are used for winds aloft forecasts?
True direction and knots.
What is the minimum weather condition required for airplanes operating under Special VFR in Class D airspace?
1 mile flight visibility.
what are the three stages of a thunderstorm?
The developing (cumulus) stage, the mature (precipitation) stage, and the dissipating (downdrafts) stage
what are the three requirements for a thunderstorm?
moisture, instability and a lifting force
Possible mountain wave turbulence could be anticipated when winds of 40 knots or greater blow
across a mountain ridge, and the air is stable.
What causes an airplane (except a T-tail) to pitch nose down when power is reduced and controls are not adjusted?
the downwash on the elevator from the propeller slipstream is reduced and elevator effectiveness is reduced.
How do variations in temperature affect the altimeter?
Pressure levels are raised on warm days and the indicated altitude is lower than true altitude.
Deviation error of the magnetic compass is caused by
certain metals and electrical systems within the aircraft.
Who is responsible for ensuring appropriate entries are made in maintenance records indicating the aircraft has been approved for return to service?
Owner or operator.
right of way rules
ballons, gliders, aircraft towing, airships, airplanes, rotorcraft
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.
What does the outbound destination sign identify?
Identifies direction to take-off runways.
The numbers 8 and 26 on the approach ends of the runway indicate that the runway is orientated approximately
magnetic.
Clouds, fog, or dew will always form when
water vapor condenses.
Steady precipitation preceding a front is an indication of
stratiform clouds with little or no turbulence.
What effect does high density altitude, as compared to low density altitude, have on propeller efficiency and why?
Efficiency is reduced because the propeller exerts less force at high density altitudes than at low density altitudes.
what regulations allows a private pilot to preform preventative maintenance?
14 CFR _SECT _43.7
An airplane and an airship are converging. If the airship is left of the airplane’s position, which aircraft has the right-of-way?
The airship.
The definition of nighttime is
the time between the end of evening civil twilight and the beginning of morning civil twilight.
When operating the transponder on the VFR code (1200), what is the minimum mode the transponder must be in?
Mode A.
Which device is a secondary flight control?
A. Spoilers
B. Ailerons
C. Stabilators
Spoilers
