Notes 2 Flashcards
What is indicated by the term ‘embedded thunderstorms’?
Thunderstorms are obscured by massive cloud layers and cannot be seen.
Where can wind shear associated with a thunderstorm be found?
On all sides of the thunderstorm cell and directly under the cell.
“light” or “chop turbulence and plane control:
slight erratic changes in altitude or attitude.
severe turbulence
plane is momentarily out of control Turbalnce
extreme turbulence
Is practically impossible to control.
If squalls are reported at your destination, what wind conditions should you anticipate?
Sudden increases in wind speed of at least 16 knots, rising to 22 knots or more, lasting for at least 1 minute.
headwind shears to be a constant tailwind, next steP
PITCH ATTITUDE: Decreases;
REQUIRED THRUST: Increased, then reduced;
VERTICAL SPEED: Increases;
IAS: Decreases, then increases to approach speed.
Which thunderstorms generally produce the most severe conditions, such as heavy hail and destructive winds?
Squall line.
\wind shear a shift from a tailwind to a headwind, what power management would normally be required to maintain a constant indicated airspeed and ILS glide slope?
Lower than normal power initially, followed by a further decrease as the wind shear is encountered, then an increase.
What is the expected duration of an individual microburst?
An individual microburst will seldom last longer than 15 minutes from the time it strikes the ground until dissipation.
Which conditions result in the formation of frost?
Temperature of the collecting surface is below the dewpoint of surrounding air and the dewpoint is colder than freezing.
upercooled large droplets (SLD), steps to take
- Disengage the autopilot. Hand-fly the airplane.
- Advise air traffic control a
- Change heading, altitude, or both to find an area that is warmer than freezing, substantially colder than the current ambient temperature, or clear of clouds.
- When severe icing conditions exist, reporting may assist other crews in maintaining vigilance.
Why is frost considered hazardous to flight operations?
Frost causes early airflow separation resulting in a loss of lift.
Your airplane is collecting ice on its tailplane. Since you can’t see it, you can realize its presence by:
The airplane’s reaction by pitching down.
How to get out of roll upset?
- Reduce the AOA by increasing airspeed or extending wing flaps to the first setting if at or below
- Set the appropriate power, and monitor the airspeed and AOA.
- If the flaps are extended, do not retract them
- Verify that the wing ice protection is functioning normally and symmetrically through visual observation of each wing. I
