Order of most initial communications: 1. 2. 3. 4. 5. Order of most initial communications: 1. YOU 2. ME 3. WHERE 4. WHAT 5. [WITH]* *Only necessary on first contact with a new control facility. What do you need to reply when ATC says, "5EC cleared to land" ? "Cleared to land, 5EC"Repeat the response to clarify you understood the instructions given, and that you'll follow them. Affirmative/Negative Pilot speak meaning "yes" or "no". Use these to respond to a question. Say ...

Thunderstorms which generally produce the most intense hazard to aircraft are? Squall line thunderstorms What are the processes by which moisture is added to unsaturated air? Evaporation and sublimation Why is frost considered hazardous to flight? Frost spoils the smooth flow of air over the wings, and therefore decreases the lift capability of an aircraft Clouds, fog, or dew will always form when Water vapor condenses Clouds are divided into four families according to their Height range

It is mostly Nitrogen(______%), Oxygen(______%), and a mix of other gases like Ozone 78,21 _________does not play a major role in weather systems unless subjected to high temperatures Nitrogen _________ _________ is important to weather because is can exist as a gas, liquid, or solid water vapor Carbon Dioxide also _______ terrestrial radiation absorbs Things in the atmosphere that are small enough to remain suspended are called ______ particulates _________is a measure of the kinetic e...

Atmosphere Complex mixture of molecules and atoms Gaseous Makeup of the Atmosphere Nitrogen, Oxygen, Argon, Carbon Dioxide Different Layers of the Atmosphere Troposphere, Stratosphere, Mesosphere, Thermosphere Sublimation Solid to gas/vapor Gas/vapor to solid Evaporation Liquid to gas/vapor

Select all characteristics that help define an airmass. Uniform moisture content Uniform Stability Uniform temperature If an airmass is colder then the ground it is moving over it is a classified as a ______________ cold airmass A maritime tropical airmass generally was what characteristics? Warm temperature, high moisture content, high dew point Typically, an advancing cold airmass has what kind of front on the leading edge? Cold front If flying through a warm front at higher altitudes,...

What are the characteristics of the flow of air around high pressure systems? Outward Downward Clockwise What are the characteristics of the flow of air around low pressure systems? Inward Upward Counterclockwise What is a Trough Line? An elongated area of low pressure. (Air rises in this area) (It is conducive to cloudiness and precipitation) What is a Ridge Line? An elongated area of high pressure. (Air moving out of a high depletes the quantity of air - therefore these are areas of ...

Natural Air Dry air + Condensation Nuclei + Water Vapor Three Cell Theory - Uneven heating from the sun - Tilt of the Earth - Coriolis Force Three Cell Theory of Circulation Air cools and descents to the upper latitudes Warm air rises and moves toward the poles Air cools and descents to the lower latitudes Between the 30o- 60o N latitude is primarily where the U.S. is located. What is the prevailing wind direction? From western / Westerly

Every physical process of weather is accompanied by, or is the result of, a a. Movement of air b. Pressure differential c. Heat exchange C. Heat Exchange What causes variations in altimeter settings between weather points? a. Unequal heating of the Earth's surface b. Variation of terrain elevation c. Coriolis Force A. Unequal heating of the Earth's surface The wind at 5,000 feet AGL is southwesterly while the surface wind is southerly. This difference in direction is primarily due to ...

The lowest layer of the atmosphere is the ____ and is approximately ____ feet at the equator and ____ feet at the poles. troposphere 60,000' 25,000' What is the difference between dry air and natural air? natural air contains water vapor and condensation nuclei Name the two major conditions affecting atmospheric circulation: uneven heating rotation of the earth

Va Design maneuvering speed. The maximum speed you can fully deflect the controls and not do damage to the airplane. Vfe Maximum Flap Extended Speed Maximum speed you could go with the flaps out to have them not break. Vle Maximum Landing Gear Extended Speed The maximum speed you can go with the landing gear down. Vmc Minimum control speed with critical engine inoperative The lowest speed you can go with one engine out. Vne Never-exceed speed (red line) If you go over a speed, the red l...
