Marked Questions 1 Flashcards
How would you describe a holding position sign?
red background with a white inscription.
To receive accurate indications during flight from a heading indicator, the instrument must be
periodically realigned with the magnetic compass as the gyro precesses.
As used with respect to the certification, ratings, privileges, and limitations of airmen, examples of a “category” of aircraft would be:
airplane; rotorcraft; glider; and lighter-than-air
The operating principle of float-type carburetors is based on the
When air flows through a venturi, a low-pressure area is created. This lower pressure causes fuel to flow from the discharge nozzle and mix with the air in the throat of the venturi.
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
reduced visibility, and in areas where flocks of birds may be expected.
The ‘No Entry’ sign identifies
paved area where aircraft entry is prohibited.
Thunderstorms may contain:
lightning, adverse winds, downbursts, turbulence, icing, hail, rapid altimeter changes, static electricity, and tornadoes.
Which items are included in the empty weight of an aircraft?
The basic empty weight of the aircraft includes unusable (residual) fuel and full engine oil. Some older aircraft only include undrainable, residual oil.
When may hazardous wind shear be expected?
a low level temperature inversion, a frontal zone, or clear air turbulence at high levels associated with a jet stream or strong circulation.
What is indicated when a current CONVECTIVE SIGMET forecasts thunderstorms?
Severe thunderstorms, lines of thunderstorms, thunderstorms with wide spread heavy precipitation, and embedded thunderstorms. Embedded thunderstorms are those obscured by massive cloud layers.
The operator of an aircraft that has been involved in an incident is required to submit a report to the nearest field office of the NTSB
when requested by the NTSB.
The suffix ‘nimbus,’ used in naming clouds, means
rain cloud.
An airplane has been loaded in such a manner that the CG is located aft of the aft CG limit. One undesirable flight characteristic a pilot might experience with this airplane would be
difficulty in recovering from a stalled condition.
What would decrease the stability of an air mass?
When air near the surface is warm and moist, suspect instability.
To receive a Hazardous Inflight Weather Advisory Service (HIWAS) in the vicinity of area 4, what frequency would you tune to?
Find the VOR box for Grand Forks VOR. The small letter “H” in the corner indicates HIWAS.
What does a runway hold position sign indicate?
This sign is located at the holding position on taxiways that intersect a runway or on runways that intersect other runways.
IF there is thunderstorm activity in the vicinity of an airport at which you plan to land, which hazardous atmospheric phenomenon might be expected on the landing approach?
Hazardous turbulence is present in all thunderstorms. Outside the cloud, shear turbulence has been noted as much as 20 miles laterally from a severe storm.
What should pilots state initially when telephoning a weather briefing facility for preflight weather information?
identify themselves as pilots and give clear and concise facts about their flight.
A precaution for the operation of an engine equipped with a constant-speed propeller is to
For any given RPM there is a manifold pressure that should not be exceeded. If manifold pressure is excessive for a given RPM, the pressure within the cylinders could be exceeded, placing undue stress on them. Follow the manufacturer’s recommendations.
The most frequent type of ground or surface-based temperature inversion is that which is produced by
The ground radiates and cools much faster than the overlying air. The air in contact with the ground becomes cold while the temperature a few hundred feet above changes very little. Thus, temperature increases with altitude.
What is manifold pressure?
vacuum pressure between the throttle and the cylinders.
What is the connection between manifold pressure and throttle?
The manifold pressure will increase as throttle is increased, due to the greater flow of fuel/air mix into the manifold (greater mass of air flowing into a fixed volume -> higher pressure). So the pressure difference will get larger as the throttle is increased.
