Stormscope & Data-link Flashcards
Stormscopes first appeared in the 1970’s as what?
The first practical airborne lightning detection system
A small receiving antenna for the storm scope is located where?
on the bottom of the fuselage.
A Stormscope or other weather mapping system operates only as:
a receiver
Stormscope is a combination of a ______ and _______ antenna in order to determine direction of the lightning strikes.
loop and sense antenna
The Stormscope is tuned to a region where radio energy of lightening is concentrated, in the very low frequency of _____.
50 KHz.
The display maps what?
the lightning strikes.
As a strike is detected, a colored dot is place on the screen that shows what?
location (direction) and distance.
The concentration of the colored dots appearing on the display show what?
the heaviest areas of lightning strikes (thunderstorm activity) and the relative direction from the nose of the aircraft
Distance of a strike is determined by:
the strength of the receiving signal and converting it to distance.
Lightening detectors of this type (Stormscope) are not as accurate in range calculations as a:
true weather radar system.
A common fault with the Stormscope type technology is:
the dots will appear closer on the display range than the actual lightening strike.
Stormscope or strike finder data information can often be ______ on navigation maps or other weather radar information.
overlaid
A weather mapping system is often installed on larger aircraft as a:
back-up or standby system in case the primary weather radar should fail.
What are installed to prevent a buildup of static electricity on the skin of the aircraft (P Static)?
Static dischargers
The dischargers are located at numerous points where P-static normally accumulates such as:
the wings, the wing tips, trailing edges of control surfaces, and the horizontal and vertical stabilizers.
A specific inspection as called out by the aircraft manufacturer must be completed and recorded where?
in the aircraft logbook
What additional services are extended to larger aircraft?
Satellite provided Data-link.
This additional system is known as __________ consisting of a network of high power ground radar stations.
NEXRAD (Next Generation Radar)
Because the NEXRAD network has high power ground stations the images they produce are:
of high quality.
A huge advantage of NEXRAD is:
the ability for the pilot to “see” in advance current weather at any location in the country.
The only system requirements for the aircraft are:
a receiving antenna, receiver, and display.
NEXRAD is a subscription based service. Who is one of the major providers?
XM/Sirius.
What are Electronic Flight bags (EFBs)?
These are tablet type devices used in the aircraft as supplemental information and as backup navigation equipment.
Weather systems data-link in light aircraft is normally what?
a standalone system
