Stormscope & Data-link

Question 1

Stormscopes first appeared in the 1970’s as what?

Answer 1

The first practical airborne lightning detection system

Question 2

A small receiving antenna for the storm scope is located where?

Answer 2

on the bottom of the fuselage.

Question 3

A Stormscope or other weather mapping system operates only as:

Answer 3

a receiver

Question 4

Stormscope is a combination of a ______ and _______ antenna in order to determine direction of the lightning strikes.

Answer 4

loop and sense antenna

Question 5

The Stormscope is tuned to a region where radio energy of lightening is concentrated, in the very low frequency of _____.

Answer 5

50 KHz.

Question 6

The display maps what?

Answer 6

the lightning strikes.

Question 7

As a strike is detected, a colored dot is place on the screen that shows what?

Answer 7

location (direction) and distance.

Question 8

The concentration of the colored dots appearing on the display show what?

Answer 8

the heaviest areas of lightning strikes (thunderstorm activity) and the relative direction from the nose of the aircraft

Question 9

Distance of a strike is determined by:

Answer 9

the strength of the receiving signal and converting it to distance.

Question 10

Lightening detectors of this type (Stormscope) are not as accurate in range calculations as a:

Answer 10

true weather radar system.

Question 11

A common fault with the Stormscope type technology is:

Answer 11

the dots will appear closer on the display range than the actual lightening strike.

Question 12

Stormscope or strike finder data information can often be ______ on navigation maps or other weather radar information.

Answer 12

overlaid

Question 13

A weather mapping system is often installed on larger aircraft as a:

Answer 13

back-up or standby system in case the primary weather radar should fail.

Question 14

What are installed to prevent a buildup of static electricity on the skin of the aircraft (P Static)?

Answer 14

Static dischargers

Question 15

The dischargers are located at numerous points where P-static normally accumulates such as:

Answer 15

the wings, the wing tips, trailing edges of control surfaces, and the horizontal and vertical stabilizers.

Question 16

A specific inspection as called out by the aircraft manufacturer must be completed and recorded where?

Answer 16

in the aircraft logbook

Question 17

What additional services are extended to larger aircraft?

Answer 17

Satellite provided Data-link.

Question 18

This additional system is known as __________ consisting of a network of high power ground radar stations.

Answer 18

NEXRAD (Next Generation Radar)

Question 19

Because the NEXRAD network has high power ground stations the images they produce are:

Answer 19

of high quality.

Question 20

A huge advantage of NEXRAD is:

Answer 20

the ability for the pilot to “see” in advance current weather at any location in the country.

Question 21

The only system requirements for the aircraft are:

Answer 21

a receiving antenna, receiver, and display.

Question 22

NEXRAD is a subscription based service. Who is one of the major providers?

Answer 22

XM/Sirius.

Question 23

What are Electronic Flight bags (EFBs)?

Answer 23

These are tablet type devices used in the aircraft as supplemental information and as backup navigation equipment.

Question 24

Weather systems data-link in light aircraft is normally what?

Answer 24

a standalone system

Question 25

The data-link establishes weather images from where?

Answer 25

the National
Weather Service radar sites to the aircraft.
