IRA Test Questions and Correct Answers
What conditions are necessary before ATC can authorize a visual approach? - Answer-You must have
the airport in sight or a preceding aircraft to be followed, and be able to proceed to the airport in VFR
conditions.
What are the main differences between a visual approach and a contact approach? - Answer-The pilot
must request a contact approach; the pilot may be assigned a visual approach and higher weather
minimums must exist.
A contact approach is an approach procedure that may be used - Answer-in lieu of conducting a SIAP.
You arrive at your destination airport on an IFR flight plan. Which is a prerequisite condition for the
performance of a contact approach? - Answer-Clear of clouds and at least 1 SM flight visibility.
Flying clear of clouds on an instrument flight plan, what are the requirements for a contact approach to
an airport that has an approved IAP? - Answer-The pilot must request the approach, have at least 1 mile
visibility, and be reasonably sure of remaining clear of clouds.
When is radar service terminated during a visual approach? - Answer-Automatically when ATC instructs
the pilot to contact the tower.
When may you obtain a contact approach? - Answer-ATC will assign a contact approach only upon
request if the reported visibility is at least 1 mile.

aircraft.
The RVR minimums for takeoff or landing are published in an IAP, but RVR is inoperative and cannot be
reported for the runway at the time. Which of the following would apply? - Answer-RVR minimums

service is not available, the missed approach action should be to - Answer-make a climbing turn toward
the landing runway and continue the turn until established on the missed approach course.

approaches provide aircraft a minimum of 1 1/2 miles radar separation between successive aircraft on
the adjacent localizer course.

approach should be initiated upon - Answer-arrival at the DH on the glide slope.
