Private Pilot VASI and Aviation Regulations Quiz

1. When flying in the airspace underlying Class B airspace, what is the maximum speed authorized?

200 knots

220 knots

180 knots

150 knots

When flying in the airspace underlying Class B airspace, the maximum speed authorized is typically 200 knots to ensure safe separation between aircrafts.

Explanation

When flying in the airspace underlying Class B airspace, the maximum speed authorized is typically 200 knots to ensure safe separation between aircrafts.

2. What is the approximate base of the cumulus clouds if the surface air temp at 1,000 feet MSL is 70 F and the dewpoint is 48 F?

5000 feet MSL

4000 feet MSL

6000 feet MSL

3000 feet MSL

To find the approximate base of cumulus clouds, you need to calculate the difference between the air temperature and dewpoint at 1,000 feet MSL. In this case, the difference is 22 F (70 F - 48 F). For every 4.4 F drop in temperature per 1,000 feet, a cumulus cloud forms. So, you need to divide the temperature difference by 4.4 to find the altitude where the temperature reaches dewpoint, which gives you 5 (22 F / 4.4 = 5). Multiply this by 1,000 feet to get the approximate base of the cumulus clouds, which is 5,000 feet. Adding the initial altitude of 1,000 feet gives a total of 6,000 feet MSL as the correct answer.

3. While on final approach to a runway equipped with a standard 2-bar VASI, the lights appear as shown by illustration D. This means that the aircraft is:

Above the glide slope

On the glide slope

Off to the side of the glide slope

The below glide slope indication from a two-bar VASI is red over red lights. This indicates to the pilot that the aircraft is below the desired glide path for a safe landing.

Explanation

The below glide slope indication from a two-bar VASI is red over red lights. This indicates to the pilot that the aircraft is below the desired glide path for a safe landing.

4. From which primary source should info be obtained regarding expected weather at the estimated time of arrival if your destination has no Terminal Forecast?

PIREP (Pilot Report)

Area Forecast

TAF (Terminal Aerodrome Forecast)

METAR Report

When a destination has no Terminal Forecast, pilots should refer to the Area Forecast for information on expected weather at the estimated time of arrival.

Explanation

When a destination has no Terminal Forecast, pilots should refer to the Area Forecast for information on expected weather at the estimated time of arrival.

5. Which cruising altitude is appropriate for a VFR flight on a magnetic course of 135 degrees?

Even thousandths minus 500 feet

Odd thousandths minus 500 feet

Odd thousandths plus 500 feet

Even thousandths plus 500 feet

For VFR flights, when flying on a magnetic course between 0 and 179 degrees, the appropriate cruising altitude is an odd thousandths plus 500 feet. This helps in maintaining vertical separation between aircraft flying in opposite directions.

Explanation

For VFR flights, when flying on a magnetic course between 0 and 179 degrees, the appropriate cruising altitude is an odd thousandths plus 500 feet. This helps in maintaining vertical separation between aircraft flying in opposite directions.
