Airspace
What airspace surrounds the nation’s busiest airports and requires ATC clearance before entry?
What is Class B Airspace?
This document contains a pilot’s route, altitude, and estimated time en route.
What is a Flight Plan?
This navigation method uses landmarks, roads, and rivers to determine position.
What is pilotage?
These lines on a weather chart connect points of equal pressure.
What are isobars?
This force opposes thrust during flight.
What is drag?
This class of airspace usually surrounds airports with an operating control tower and radar approach control.
What is Class C Airspace/
This rule requires pilots to have enough fuel to reach their destination plus reserves.
What is fuel reserve requirement?
This heading is corrected for magnetic variation and deviation.
What is compass heading?
This chart shows terrain, obstacles, and airspace information for pilots.
What is a sectional aeronautical chart?
This FAA document proves an aircraft is airworthy?
What is an airworthiness certificate?
This airspace begins at either 700 or 1,200 feet AGL around airports where instrument procedures are available.
What is Class E Airspace?
This navigation aid provides both distance and direction from a station.
What is VOR/DME?
This instrument measures an aircraft’s direction relative to magnetic north.
What is the heading indicator?
This weather phenomenon can cause severe lift loss and turbulence near mountains.
What is mountain wave turbulence?
This airport marking identifies the beginning of a runway available for landing.
What is a threshold marking?
Pilots do not need ATC clearance to enter this uncontrolled type of airspace.
What is Class G Airspace?
This weather briefing includes adverse conditions, forecasts, and NOTAMs.
What is a standard briefing?
This term describes the aircraft’s actual path over the ground.
What is track?
This METAR abbreviation means visibility is greater than 10 statute miles.
What is “10SM”?
This frequency is commonly used for emergency aircraft communications.
What is 121.5 MHz?
This special use airspace warns pilots of unusual aerial activity but does not restrict entry.
What is Warning Area?
This chart is commonly used for low-altitude VFR cross-country flying.
What is a sectional chart?
This GPS term means the direct route between two waypoints.
What is direct-to navigation?
This cloud type is most associated with thunderstorms.
What is Cumulonimbus Cloud?
This principle explains how faster airflow creates lower pressure over a wing.
What is Bernoulli’s Principle?
