IRA Exam Review Questions and
Answers
RVR - Answer-Runway Visual Range
2,400 RVR = 1/2 SM
Pressure altitude - Answer-Set altimeter to 29.92" and read indicated alt
Correct altimeter setting allows the altimeter to read - Answer-True altitude at field elevation
Pressure altitude is the altitude read on your altimeter when the instrument is adjusted to indicate
height above - Answer-the standard datum plane
When on the proper glide path of a 2-bar VASI, the pilot will see the near bar as - Answer-white and the
far bar as red
To comply with ATC instructions for altitude changes of more than 1,000', what rate of climb or descent
should be used? - Answer-As rapidly as practicable to 1,000' above/below the assigned altitude, and
then between 500 and 1,500 feet per minute until reaching the assigned altitude
, ATC may assign the MOCA when certain special conditions exist, and when within - Answer-22 NM of
VOR
Coriolis Illusion - Answer-While making prolonged constant rate turns under IFR conditions, an abrupt
head movement can create the illusion of rotation on an entirely different axis
Roll upsets caused by ice accumulation forward of the ailerons can be remedied by - Answer-reducing
angle of attack by increasing airspeed or extending wind flaps to the first setting and, if in a turn, rolling
wings level
If you experience icing during an approach, you should - Answer-Retract flaps as necessary and
disengage the autopilot
Where would you see the first sign of ice buildup? - Answer-Pitot tube
SLD - Answer-Supercooled large droplets (SLD) can be present at high altitude even without
precipitation
The sensory system responsible for most of the illusions leading to spatial disorientation is the -
Answer-Vestibular system
Where will the pilot first notice an accumulation of ice? - Answer-Air temperature probe
At a constant indicated altitude and constant power, the outside air temp becomes warmer than
standard. The true airspeed will - Answer-Increase
While on glideslope for an ILS approach, a tailwind shears to a headwind. This is - Answer-Extremely
hazardous because the aircraft will have a decreased power setting as it encounters the headwind
