Prep-ware Exam: Instrument Rating
Airplane (IRA)
The presence of ice pellets at the surface is evidence that: - Answer-There is freezing rain at a higher
altitude.
The strength and location of the jet stream is normally: - Answer-Weaker and farther north in the
summer.
(Refer to Figure 13.) If involved in a microburst encounter, in which aircraft positions will the most
severe downdraft occur? - Answer-3 and 4.
Which are characteristics of an unstable cold air mass moving over a warm surface? - Answer-
Cumuliform clouds, turbulence, and good visibility.
What type of clouds will be formed if very stable moist air is forced up slope? - Answer-Stratified clouds
with little vertical development.
What actions should the pilot take in the event of suspected tailplane icing during an approach? -
Answer-Use partial or no flaps and no autopilot.
, When does the National Weather Service release an Aviation Notification Watch Message (SAW)? -
Answer-Unscheduled and issued as required.
(Refer to Figure 7.) What type of weather can be expected in the red scalloped area near area 9? -
Answer-Isolated embedded cumulonimbus with tops at FL330.
If you encounter in-flight icing and ATC asks you to report your conditions, what are the official
reportable icing values that you are expected to use? - Answer-Trace, light, moderate, severe.
When is the wind-group at one of the forecast altitudes omitted at a specific location or station in the
Winds and Temperatures Aloft Forecast (FB)? When the wind: - Answer-At the altitude is within 1,500
feet of the station elevation.
What significant sky condition is reported in this METAR observation?METAR KBNA 1250Z 33018KT
290V360 1/2SM R31/2700FT +SN BLSNFG VV008 00/M03 A2991 RMK RERAE42SNB42 - Answer-Sky is
obscured with vertical visibility of 800 feet.
The local altimeter setting should be used by all pilots in a particular area, primarily to provide for: -
Answer-Better vertical separation of aircraft.
What CAS must be used to maintain the filed TAS of 155 knots at 8,000 MSL if the outside air
temperature is -5 degrees C? - Answer-139 KCAS.
If a half-standard rate turn is maintained, how long would it take to turn 135°? - Answer-1 minute 30
seconds.
The primary flight display (PFD) receives attitude and heading data from the: - Answer-AHRS.
