Lesson 18 Flashcards
How often are Sectionals Published?
every 6 months
What are Sectionals used for primarily?
pilotage
_______ are designed to be used by slow and medium speed aircraft flying on Visual Flight Rules (VFR).
Sectional Aeronautical Charts
Map Scale of a Sectional Chart
1:500,000 (1 inch= 6.86 Nautical Miles)
Maximum Elevation Figures (MEF)
shown in each quadrangle on the chart bounded by lines of lat and long; large # represents thousands of feet, small # represents hundreds of feet above MSL (125)
Basic terrain contour lines are generally spaced at _____ ft intervals.
500
Changes in elevation are indicated by changes in color or tint for easy recognition. At what spacing do colors change?
every 1,000 ft
Airports with control towers are always depicted _______.
in the color blue
In the airport data “450 L 51 122.7,” the letter “L” indicates ___________.
the airport has runway lighting
In the airport data “4500 L 72 122.95,” “4500” is the _______.
airport elevation above sea level
A pilot can receive Hazardous Inflight Weather Advisory Service (HIWAS) broadcasts via the voice portion of a navigational aid if its communications box has a(n) ____________.
blue filled in circle with a white H
The boundary of Class B airspace is always depicted in what color?
blue
The height of an obstruction is indicated on the chart in feet above ________.
both ground level and sea level
__________ depict Class B airspace which provides for the control and separation of all aircraft operating within that airspace.
VFR Terminal Area Charts (TACs)
Map Scale of TACs
1:250,000 (1 inch=3.43NM)
What chart contains the greatest amount of detail of all VFR navigation charts?
TACs
Flyway Charts
Located on the backside of TAC charts; not used for flight planning; shows pilot where to avoid busy traffic flow areas around the airspace
How often are TACs published?
6 months
__________ are designed to be used for visual navigation; due to smaller scale, they are used mostly by moderate speed aircraft
World Aeronautical Charts (WACs)
Map Scale of WACs
1:1,000,000 (1 inch=13.7 NM)
How often are WACs published?
every 12 months
____________ is designed primarily as a pilot’s operational manual, and includes much more detailed information about airports and navigational aids than can be found on any chart.
Airport/Facility Directory (A/FD)
How often is the A/FD published?
every 56 days
When would an A/FD be helpful for a controller to use?
when relaying airport information to a pilot upon request; recommending a suitable airport in the event of an emergency
