Which factor would tend to increase the density altitude at a given airport?
An increase in ambient temperature.
Hot air = thin air = what planes experience at higher elevation. On a hot day, the air becomes “thinner” or lighter and its density is equivalent to a higher altitude in the standard atmosphere, thus the term “high-density altitude”.
Which combination of atmospheric conditions will reduce aircraft takeoff and climb performance?
High temperature, high relative humidity and high density altitude.
High = worse performance. An increase in Air temp or humidity or a decrease in air pressure (which results in a higher density altitude) will significantly Decrease both POWER output and PROP efficiency.
What effect does high density altitude have on aircraft performance?
It reduces climb performance.
High = worse performance. An increase in Air temp or humidity or a decrease in air pressure (which results in a higher density altitude) will significantly Decrease both POWER output and PROP efficiency.
What effect, if any, does high humidity have on aircraft performance?
It decreases performance.
High = worse performance. An increase in Air temp or humidity or a decrease in air pressure (which results in a higher density altitude) will significantly Decrease both POWER output and PROP efficiency.
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.
The prop produces thrust in proportion to the mass of air being accelerated through the rotating blades. If the air is less dense, propeller efficiency is decreased.
At what angle do lines of longitude cross the equator?
Lines of longitude cross the equator at right angles.
Meridians of longitude encircle the earth from pole to pole and all meridians cross the eqquator at right angles.
When converting from True Course to Magnetic Heading, a pilot should do what with Variation and Wind Correction Angles?
Add westerly variation and subtract left wind correction angle.
When converting a TC to a TH, subtract a left wind correction angle or add a right wind correction angle. When converting from a true heading to a a magnetic heading, add westerly variation or subtract easterly variation.
What is the minimum pilot certification required for operation within Class B airspace?
Private Pilot Certificate or Student Pilot Certificate with appropriate logbook endorsements
It is generally true that no person may operate a civil aircraft within Class B airspace unless the pilot in command holds at least a PPL or a student pilot has the proper logbook endoresements. However, there are some Class B airports which never permit students, even if they have the proper endorsements.
What minimum radio equipment is required for VFR operation within Class B airspace?
Two-way radio communications equipment, a 4096-code transponder, and an encoding altimeter.
Unless otherwise authorized by ATC, no person may operate an aircraft within Class B airspace unless that aircraft is equipped with an operable two-way radio capable of communications with ATC, a transponder with applicable altitude reporting equipment, and an encoding altimeter.
A Blue Segmented circle on a sectional chart depicts which class airspace?
Class D.
A blue segmented circle depicts Class D Airspace, which means a control tower is in operation.
Airspace at an airport with a part-time control tower is classified as Class D airspace only
when the associated control tower is in operation.
Class D airspace means a control tower is in operation. If the tower closes, it reverts to Class E airspace.
The lateral dimensions of Class D airspace are based on
the instrument procedures for which the controlled airspace is established.
The dimensions of class D airspace are AS NEEDED for each individual circumstance. The airspace may include extensions as necessary for IFR arrival and departure paths.
When a control tower, located on an airport within Class D airspace, ceases operation for the day, what happens to the airspace designation?
The airspace reverts to Class E or a combination of Class E and G airspace during the hours the tower is not in operation.
Class D airspace means a control tower is in operation. If the tower closes, it reverts to Class E airspace (if the weather observer is present or the weather system is automated) or Class G airspace (at the airports where the tower controllers are also the weather observers).
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.
Radio communications must be established and maintained with the primary control tower even when operating to and from a non-tower airport located within the lateral limits of Class D airspace. On takeoff, from a satellite airport, communications must be established as soon as practicable after takeoff
Two way radio communication must be established with the ATC facility having jurisdiction over the area prior to entering which class airspace?
Class C.
Two way radio communication must be established with the ATC facility having jurisdiction over the lass C airspace prior to entry and thereafter as instructed by ATC.
Which initial action should a pilot take prior to entering Class C airspace?
Contact approach control on the appropriate frequency.
Radio contact is required to operate in Class C airspace, but permission is not required.
The vertical limit of Class C airspace above the primary airport is normally
4,000 Feet AGL
Class C airspace consists of two circles, both centered on the primary Class C airspace airport. The surface area has a radius of 5 NM. The shelf area usually extends from the surface of the Class C airspace up to 4000 ft above the airport.
The airspace area between the 5 and 10nm rings usually begins at 1200 AGL and also extends to 4000 ft AGL.
The radius of the procedural Outer Area of Class C airspace is normally
20 NM
All operations within Class C airspace must be in
An aircraft equipped with a 4096-code transponder with Mode C encoding capability
Aircraft operating in Class C airspace must have a Mode C transponder.
Under what condition may an aircraft operate from a satellite airport within Class C airspace?
The pilot must contact ATC as soon as practicable after takeoff.
For aircraft departing a satellite airport, two way radio communication must be established as soon as practicable and thereafter maintained with ATX while within the area.
What minimum radio equipment is required for operation within Class C airspace?
Two way radio communications equipment, a 4096 code transponder, and an encoding altimeter.
Normal VFR operations in Class D airspace with an operating control tower require the ceiling and visibility to be at least:
1,000 feet and 3 miles of visibility.
No person may operate an aircraft under VFR within the lateral boundaries of the surface areas of Class B, Class C, Class D, or Class E airspace designated for an airport when the ceiling is less than 1000 feet. The flight visbility and cloud clearance for VFR operations in Class D airspace is 3SM visibility, 500 feet below, 1000 feet above, and 2000 feet horizontal from all clouds.
Unless otherwise authorized, where are two-way radio communications with ATC are required for landings or takeoff
At all tower controlled airports regardless of weather conditions.
No person may operate an aircraft to, from, or on airport having a control tower operated by the US unless two-way radio communications are maintained between that aircfraft and the control tower.
Unless otherwise specified, Federal Airways include that Class E airspace extending upward from (what altitude?)
1,200 feet above surface up to an including 17,999 feet MSL
Federal airways are part of the Class B, C, D, or E airspace. They are eight miles wide, four miles either side of the centerline. They usually begin at 1200 AGL and continue up to buy not including 18000 MSL, or FL180.
