Advanced Weather
Stable air is most likely to produce these smooth layered clouds.
What are stratus clouds?
A sectional chart uses this color to depict Class B airspace.
What is blue?
In most airspace below 10,000 feet MSL, the speed limit is this many knots.
What is 250 knots?
This force opposes thrust.
What is drag?
During run-up, a large magneto drop may indicate this type of issue.
What is a fouled spark plug/magneto problem?
A temperature inversion can trap this near the ground.
What is fog/smoke/haze?
This navigation method uses checkpoints and timing along the ground.
What is pilotage and dead reckoning?
Student pilots cannot carry these during solo flight.
What are passengers?
Bernoulli’s Principle explains how faster airflow creates this.
What is lower pressure?
If oil pressure suddenly drops to zero in flight, the pilot should do this first.
What is prepare for an emergency landing/check engine operation?
The leading edge of a thunderstorm often contains this dangerous wind phenomenon.
What is a gust front?
The line drawn between points on a sectional for navigation is called this.
What is a course line?
Class E airspace typically begins at this altitude in many areas.
What is 1,200 feet AGL?
Exceeding the critical angle of attack causes this.
What is a stall?
A flashing green light gun signal to an aircraft in flight means this.
What is cleared to land?
Clouds, precipitation, and poor visibility are commonly found along this type of front.
What is a warm front?
This radio navigation system uses radials from a ground station.
What is VOR?
This airspace surrounds the nation’s busiest airports.
What is Class B airspace?
The tendency of an aircraft to return to straight-and-level flight after being disturbed is called this.
What is stability?
Spatial disorientation is especially dangerous in these conditions.
What are IMC/night conditions?
This icing type forms when small supercooled droplets freeze rapidly on impact.
What is rime ice?
When using dead reckoning, pilots primarily rely on time, heading, airspeed, and this fourth element.
What is distance?
A Mode C transponder is generally required within this many nautical miles of Class B airports.
What is 30 nautical miles?
Newton’s Third Law explains lift because air pushed downward causes this reaction.
What is the aircraft moving upward?
This checklist is used during engine failure in flight to help restart the engine or secure it.
What is the emergency checklist?
