How many modes does the radar have?
What are they? |

Term
When you are in MGM and select DBS, what is the range limitation?
If you are outside this range limitation what happens?
Are scan rates slower or faster in MGM vs. DBS? |
|
Definition
Range limitation for DBS is 40 miles or less.
If you are outside this range MGM will be selected
DBS scan speeds are considerably slower than MGM |
|
|
Term
|
Definition
| A ground mapping mode that incorporates both MGM and DBS processing and operates out to 40 nm. |
|
|
Term
|
Definition
The map mode provided during degraded radar operations when incomplete stabilization data is being recieved in the radar from the INU (stab lost condition)
In this mode, radar ranges are in slant ranges rather than ground ranges and format is not corrected for airplane roll. |

Term
| What are the two levels of position updates available? |
|
Definition
|
|
Term
How do you know if your position update is in precision mode after you have selected PREC?
What does precision mode provide/measure in addition to MGM or MSDBS?
Does PREC work in MSDBS mode? |
|
Definition
The radar will show the cursor mode field in reverse video.
PREC mode will measure the height of the ground as well as INU velocity errors.
It can, but in MSDBS it is not normally available. |

Term
THE MQF says that turbulence information is only good up to the 80nm range. Is this completely accurate?
What does turbulence look like on the radar screen? |
|
Definition
Yes and No, the 80 mile ring is the highest ring that will show turbulence data, however, turbulenbce will only be shown up to 50nm with only weather being shown out to 80.
Flashing white fill |

Term
| what are the colors for light, moderate, heavy and excessive rain rates? |
|
Definition
| green=light, yellow=moderate, red=heavy, magenta=excessive |

|
Term
| What are the three ranges/levels of wind shear and how are they depicted? |
|
Definition
Level 1 - >3nm - "Windshear Warning" message on screen
Level 2 - "windshear caution" - 1.5 to 3 nm
Level 3 - "Windshear Warning" - 1.5 or less |

Term
How far does the beacon mode work out to?
How do you select ground beacon and air beacon? |
|
Definition
40nm
press BCN once and you are in ground mode, press it twice and you are in air mode |

Term
How far does Skin Paint SP mode go to?
What are the clutter notch selections (speeds)?
What is the size of the square displyed in relation to?
|
|
Definition
20 nm
55, 70 & 110
The size of the square is related to the RCS radar cross section |
|
|
Term
| If you get a flashing OVTEMP message, do you need to shut the radar down? |
|
Definition
| No, to prevent damage to the system, the radar will automatically shut down if the temperature conntinues to increase. |
|
|
Term
| Does the pilot's or navigators radar power switch initiate the startup BIT? |
|
Definition
| Either one can initiate the startup BIT. |
|
|
Term
| How far out does WX mode work to? |
|
Definition
|
|
Term
| What does the iso-echo (ISO) button do? |
|
Definition
It steps sequentially through light, moderate and heavy rain intensity thresholds.
IQ-22 |

|
Term
When can PREC mode be used?
How many scans do we have in PREC? |
|
Definition
Either in an offset or expnaded scope, with the cursor in CMPR or GRND.
Both scans. |
|
|
Term
What does +1150R mean on the scope?
What does +6800S mean on the scope?
|
|
Definition
| The R indicates that the altitude is coming from the radar altimeter. The S indicates that it is getting the altitude from SCNS. below 5000 the radar uses the rad alt, above it uses scns. |
|
|
Term
What does (STAB LOST) mean?
What does the radar default to?
Are there any other modes available? |
|
Definition
Indicates that the radar is not recieving valid altitude, velocity and position data from the navigation system.
RBGM
WX & BCN
note: flight plan overlay will not be available and HDG up will be the only orientation |
|
|
Term
| What does the OUT OF CAL message indicate? |
|
Definition
| Indicates that the WX or WS mode has been altered from its calibrated or default position |
|
|
Term
| When do you get a LOCK OUT message? |
|
Definition
| When the operator does not have radar control or when the operator attempts to select a mode that is unavailable. |
