Objective: To determine that the applicant:

Private Pilot PTS What this means… What you need to do to prepare
1. Exhibits satisfactory knowledge of the elements related to weather information by analyzing weather reports, charts, and forecasts from various sources with emphasis on –

a. METAR, TAF, and FA.
b. surface analysis chart.
c. radar summary chart.
d. winds and temperature aloft chart.
e. significant weather prognostic charts.
f. convective outlook chart.
g. AWOS, ASOS, and ATIS reports.
h. SIGMETs and AIRMETs.
i. PIREPs.
j. windshear reports.
k. icing and freezing level information.

Using the weather briefing you obtained for the cross country flight, you will be asked to interpret and analyze weather products. 

  • METAR – how often issued, how long valid?  Cloud heights AGL or MSL?
  • TAF – include when issued, effective period
  •  FA – include when issued, effective period
  • Surface Analysis Chart – what is a high pressure area and what type of weather is associated with it?
    What is a low pressure area and what type of area is associated with it?
    What are the four type of weather fronts and what type of weather is associated with each?
    What type of change in the weather can be expected before and after frontal passage?
    What type of weather is associated with a trough?
    What type of weather is associated with a ridge?
    What are isobars?
    How is marginal VFR and IFR areas displayed on this chart?
  • Weather depiction chart – what information is depicted? how are MVFR and IFR conditions depicted?
  • radar summary chart – what do the number associated with radar returns indicate? What does the color of the return indicate?
  • winds and temperature aloft chart – interpret the datablock for the SAC reporting station at 6,000 and 9,000 ft
  • significant weather prognostic charts – What period and area is depicted in each panel? How are MVFR and IFR conditions depicted in each panel?
  • convective outlook chart – what conditions are depicted on this outlook chart?
  • AWOS, ASOS, and ATIS reports – what weather information is communicated in these reports?
  • What are AIRMETs, SIGMETs, Convective SIGMETs? What types of hazards are classified as AIRMETs and SIGMETS?
  • What are PIREPs? How do you PIREPs? How do you give a PIREP?
  • Icing and freezing level – from which weather products can you obtain information about icing and freezing levels?
Use Aviation Weather Center to practice decoding and interpreting weather products:

2. Makes a competent “go/no-go” decision based on available weather information. You will be asked questions such as:

What process do you use to interpret a weather forecast and make a go/go-go decision?

What are your personal weather minimums and how do you apply them when interpreting a forecast?

Review How to obtain a good weather briefing

Review the General Aviation Pilot’s Guide Preflight Planning, Weather Self-Briefings, and Weather Decision Making

Read Getting the maximum from personal minimums. Fill out and print the personal minimums
