Avit 102 Block 5

What does the PAVE model stand for in aeronautical decision making?

Pilot, Aircraft, Environment, External pressures.

What should pilots ensure before flying regarding medications?

Pilots must know how medications impact them before flying.

What is dark adaptation and how long does it take?

Dark adaptation is the process of the eyes adjusting to low light conditions and takes about 30 minutes.

What effect does a wider runway illusion have on approach perception?

It makes a pilot think they’re closer to the runway, causing them to fly a higher approach.

What are the three stages of a thunderstorm?

Cumulus, mature, and dissipating.

What is the main ingredient necessary for thunderstorm development?

Moisture, lifting, and instability.

What type of fog forms when warm, moist air moves over a cooler surface?

Advection fog.

What does AIRMET Sierra indicate?

IFR conditions.

What does the term 'low level wind shear' refer to?

A sudden and drastic change in wind speed and/or direction over a small area.

What kind of turbulence is caused by buildings and obstacles on the surface?

Mechanical turbulence.

How do low pressure systems affect weather?

They typically lead to bad weather with counterclockwise flow.

What is the significance of the tropopause in aviation?

It is the boundary layer where the jet stream is typically found.

What are the three types of airplane icing?

Glaze, rime, and mixed.

What type of report is a UA?

A normal pilot report.

What is the effect of temperature inversions on turbulence?

Temperature inversions create stable air with no turbulence.

What does a Convective SIGMET indicate?

Severe conditions associated with a storm, valid for 2 hours.

What causes the visual illusion known as the 'black hole' approach?

It occurs when there are no lights visible at night, creating a disorienting effect.

What types of fronts are there in meteorology?

Cold, warm, occluded, and stationary fronts.

What is the weather phenomenon where water is cooler than land during the day?

Sea breeze.

How do brighter than expected lights affect aircraft approach?

They make pilots feel closer to the runway, leading to a higher approach.

What is the effect of stress on pilot performance?

It can negatively impact decision making and flying capabilities.

What determines the stability of the atmosphere?

The combined effects of temperature and moisture.

What is reported in a graphical forecast?

Visual representation of possible weather conditions.

What is the purpose of aviation weather briefings?

To inform pilots about current and expected weather conditions.

What are the hazards of thunderstorms?

Tornadoes, hail, turbulence, and lightening.
