Little Wings Flashcards
In reference to aircraft altitude, what do the colours green, yellow and red represent in the KMD 550/850 EGPWS?
Green - terrain/obstacles are below aircraft altitude
Yellow - terrain/obstacles are at or above aircraft altitude
Red -terrain/obstacles are at least 2000’ above aircraft altitude
How is do you test the KMD 550/850 EGPWS?
It will self test on startup. For a manual test, select the outer rotary knob to “TST”
What does the tiny “F” represent in between the range keys?
What actions should be taken?
A system hardware fault exists. Recycle unit power; if fault re-occurs the unit must be serviced.
How do you display the colour key in the TOPO ON mode of the KMD 850?
Move the joystick pointer to any area and select “MORE INFO”
What message indicates invalid GPS position data?
NO EXTERNAL POSITION DATA
How do you enable and disable Autozoom on the KMD 850?
RNG UP on 2000nm, or hold either range key for 2s+. Pressing either range key or having an invalid flight plan will cancel Autozoom.
Active Autozoom is indicated by small black text next to the range setting.
How can you manually test the Stormscope?
On the KMD, AUX - WX SETUP - SOTRM SCOPE - NOISE/STRIKE/SELF TEST
The Sotrmscope will self test several times a minute
Is normal to receive a NO DATA RECEIVED FROM STORMSCOPE message during the Stormscope self test?
Yes
What will inhibit Stormscope stikes from being overlaid on the KMD Map display?
Invalid heading information
How do you clear discharge points on the KMD 850?
Move the joystick
Regarding discharge points, what is indicative of a thunderstorm building and dissipating?
Building - discharge points reappear faster and in larger numbers
Dissipating - discharge points reappear slower and in smaller numbers
What is the primary difference between Strike Mode and Cell Mode on the Stormscope?
Strike Mode displays all lightning strikes with an “x” within the selected view. It is most useful during light electrical activity to potentially identify a building thunderstorm faster than Cell Mode.
Cell Mode will only plot strikes with a “+” and which are associated with a cluster of other strikes as well as strikes within 25nm of the aircraft. It is most useful during periods of heavy electrical activity and will indicate the areas in which cells are present.
How can the flight plan be overlaid on the KMD WX page?
OVLY - FLIGHT PLAN
Vice versa for Map Mode
What action should be taken using the Stormscope after receiving erroneous indications during taxi?
Clear the screen
Does the Traffic Alerting System provide TA and RA information?
No, it only provides TA
What does the arrow represent on the TAS display?
The intruder is climbing or descending at 500+fpm
How is a TA displayed in Map Mode?
A yellow TRFC is displayed and if auto pop-up is enabled the traffic display will be presented
What is “No Bearing Traffic”?
traffic recorded by the TAS of which the bearing cannot be detected. Traffic information is displayed in the top right corner of the MFD. Up to two intruders can be displayed.
What view options are available in the TAS display of the KMD 850?
Normal, Above, Below and Unrestricted
How is the KMD 850 TAS tested?
A test is performed by using the outer knob to TST. A successful test will indicate one of each symbol. A failed test is indicated by a yellow “TAS FAIL” and the associated system fault.
What is the difference between Wx and WxA on the RDR2000?
Wx displays the static colours (green -weak, yellow-moderate, red-heavy, magenta-intense)
WxA displays the intense returns as flashing black and magenta
What colours are displayed in GND MAP mode on the RDR2000?
Green, Yellow and Magenta
Do radar transmissions occur when the RDR2000 is tested?
No
What is the STBY function on the RDR2000?
It fully energizes the radar but does not emit radar transmissions. The antenna is parked at 0 degrees.
How is a successful test of the RDR2000 displayed?
To test, select TST and tilt up 7 degrees. The test pattern displays all colours along the arc as the small ripple moves along the outer edge in the 80nm range.
Returns should be evident if the radar is selected ON and aimed at obstacles…
Is the RDR2000 active in ON and LOG modes?
It is always active in ON unless a strut switch is fitted. It will be active in LOG mode if it is not interfaced with a graphics unit.
What does RADAR stand for?
RAdio Detecting And Ranging
In the RDR2000 how is a target alert indicated?
Two red arcs at the top of the screen. It only functions in Wx/WxA from 80nm-240nm.
What can cause altitude rings on the RDR 2000?
The shape and physical condition of the nose cone can reflect side lobes down to the ground which are then received by the radar. These will occur at approximately Inm per 6000’ of altitude.
What are the four radar returns indicative of hail?
Hooks, fingers, scalloped edges and U-shaped edges.
They appear suddenly, along any edge of the storm and change in intensity in a matter of seconds.
Weak or fuzzy projections are not normally associated with hail.
Any ragged edges, steep gradients or rapid changes in shape or intensity will contain severe turbulence.
How should the RDR 200 tilt be managed to optimise weather targets?
In the 40/80nm range, adjust the tilt to fill the display with ground return.
tilt up until the outer third of the display is ground return.
If a return continues strong into the lower thirds of the display it is a hazardous storm/s.
If shadows are detected behind strong returns then there is hazardous weather there too.
How is the Vertical Path mode operated on the RDR 2000?
Set the azimuth use the TRK buttons then select VP.
All symmetrical images represent ground return. Any asymmetrical images are weather returns.
How many degrees of tilt inaccuracy is satisfactory before the RDR 2000 should be serviced?
2 degrees from one side to the other. This can be checked scanning the ground return or via the STAB test.
When will the “STAB LMT” warning enunciate on the RDR 2000?
when the combined pitch and roll exceed 30 degrees. It will remain on until the attitude is restored to within limits.
How can the RDR 2000 Stabilisation be checked?
Select MAP - STAB OFF
Set 20NM
GAIN MAX
Fly straight and level
Tilt down to show ground return to the third range mark. If the inner ring is not parallel then the antenna bracket is not mounted correctly.
Turn STAB on. If the figure is lopsided then adjust with the ROLL TRIM using a screwdriver until it appears parallel.
Roll the aircraft and check again.
How is the KFC 225 AFCS tested?
A self test on startup is indicated by PFT on the display. A red “P” may be indicated momentarily on the face of the autopilot indicating pitch is not available during the test.
