Question | Answer |
---|---|
What does gyroscopic mean? | pertaining to fast rotation of an object on a vertical axis |
What are the three gyroscopic instruments in the "six-pack" of the plane? | attitude indicator, heading indicator, turn coordinator |
What are the three pitot-static instruments? | air speed indicator, altimeter, vertical speed indicator |
What does an altimeter measure? | altitude above sea level |
What is the movement of fluids? | from areas of high pressure to low pressure |
How does the shape of the plane's wings help it achieve lift? | the flat bottom of the airfoil creates high pressure underneath the airfoil and low pressure above, making it move up |
What is Bernoulli's Effect? | if you increase the speed of a fluid, its pressure will decrease. |
What is an upside-down airfoil called? | a spoiler |
What is a water airfoil called? | hydrofoil |
What are the four forces of flight? | lift, gravity (weight), thrust, and drag |
What is Newton's first law of motion? | an object in motion will stay in motion in a straight line at a constant speed, and an object at rest will stay at rest. |
What is newton's second law? | F=ma |
What is Newton's third law? | Every action has an equal and opposite reaction |
What are the three axes of flight? | yaw, pitch, roll |
Which way is yaw? | left to righ |
Which way is pitch? | up and down |
Which way is roll? | around |
Around which axis does yaw occur? | vertical axis |
Around which axis does pitch occur? | lateral (wing) axis |
Around which axis does roll occur? | longitudinal (fuselage) axis |
What part of a plane controls yaw? | the rudder (located along the vertical stabilizer) |
What part of a plane controls pitch? | the elevator (located along the horizontal stabilizer) |
What part of a plane controls roll? | the ailerons (located on the outer edge of the wing) |
What are the primary types of clouds? | cirrus, cumulus, stratus |
What are characteristics of a cirrus cloud? | wispy, ice crystals, "mare's tail", sign of weather change for the worse in 24-48 hours |
What are the characteristics of a cumulus cloud? | fluffy, white, sign of fair weather |
What are the characteristics of a stratus cloud? | overcast, gray, low, possibly fog if it gets too low |
What does nimbo/nimbus mean? | precipitation: hail, sleet, rain, snow |
What are the clouds pilots have to watch out for? | fog, cumulonimbus, nimbostratus |
What is a cumulonimbus cloud and what happens with it? | thunderstorm cloud, lightning, hail, torrential rain, tornadoes, high winds, microburst (down draft) |
What does IFR stand for? | instrument flight rules |
What does VFR stand for? | visual flight rules |
What are the rules of a VFR pilot? | see 3 miles in an given direction minimum; if clouds, you either have to stay 1) 500 feet below, 2) 1000 feet above, or 3) around by a horizontal distance of 2000 feet |
What is a METAR? | gives weather reports at a specific airport, usually every hour |
What is a TAF? | terminal area forecast. it's like a METAR but judges ahead. |
Where can I get my METAR? | aviationweather.gov |
What is the METAR symbol for Lawrenceville Brisco Field? | klzu |
What is the METAR symbol for Hartsfield-Jackson airport? | katl |
What is the METAR symbol for Peachtree? | kpdk |
What is a dangerous landing? | cross-wind landing |
How do I go from Greenwich time to our time zone? | minus 500 (from the hundreds spot, of course) |
In a METAR, what does RA stand for? | rain |
BKN? | broken clouds |
SKC? | clear skies |
SCK | scattered |
What are the three ways a plane can stall? | too much pitch (full stall), not enough air movement over the wings (slow stall), when the wings can't achieve lift (ex: when ice forms) |
See your charts for details. |
