To track outbound on the 180 radial of a VOR station, the recommended procedure is to set the OBS to

180° and make heading corrections toward the CDI needle.

An aircraft 60 miles from a VOR station has a CDI indication of one-fifth deflection, this represents a course centerline deviation of approximately

2 miles.

When must an operational check on the aircraft VOR equipment be accomplished to operate under IFR? Within the preceding

30 days.

If an aircraft is consuming 9.5 gallons of fuel per hour at a cruising altitude of 6,000 feet and the groundspeed is 135 knots, how much fuel is required to travel 420 NM?

30 gallons.

When using VOT to make a VOR receiver check, the CDI should be centered and the OBS should indicate that the aircraft is on the

360 radial.

If an airplane is consuming 12.5 gallons of fuel per hour at a cruising altitude of 8,500 feet and the groundspeed is 145 knots, how much fuel is required to travel 435 NM?

8,500 feet.

For IFR operations off established airways, ROUTE OF FLIGHT portion of an IFR flight plan should list VOR navigational aids which are no more than

80 miles.

Which data must be recorded in the aircraft logbook or other record by a pilot making a VOR operational check for IFR operations?

Date of check, place of operational check, bearing error, and signature.

What procedure could a pilot use to navigate under VFR from one point to another when ground references are not visible?

Dead reckoning.

Which situation would result in reverse sensing of a VOR receiver?

Flying a heading that is reciprocal to the bearing selected on the OBS.

How should the pilot make a VOR receiver check when the aircraft is located on the designated checkpoint on the airport surface?

Set the OBS on the designated redial. The CDI must center within plus or minus 4° of that radial with a FROM indication.

True course measurements on a Sectional Aeronautical Chart should be made at a meridian near the midpoint of the course because the

angles formed by lines of longitude and the course line vary from point to point.

(Refer to Figure 17.) Which statement is true regarding illustration 2, if the present heading is maintained? The airplane will

cross the 180 radial at a 45° angle outbound.

(Refer to Figure 17.) Which is true regarding illustration 4, if the present heading is maintained? The airplane will

cross the 180 radial at a 75° angle.

As air temperature increases, density altitude will

increase.

When navigating using only VOR/DME based RNAV, selection of a VOR NAVAID that does not have DME service will

result in loss of RNAV capability.

When the CDI needle is centered during an airborne VOR check, the omnibearing selector and the TO/FROM indicator should read

within 6° of the selected radial.
