Electronic Navigation and Flight Instruments Flashcards
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.
To track outbound on the 180 radial of a VOR station, the recommended procedure is to set the OBS to
180 degrees and make heading corrections toward the CDI needle.
What record shall be made in the aircraft log or other permanent record by the pilot making the VOR operational check?
The date, place, bearing error, and signature.
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 radial. The CDI must center within plus or minus 4 degrees of that radial with a FROM indication.
What is a consideration when using a hand-held GPS for a VFR navigation?
Position accuracy may degrade without notification.
What is an operational differences between the turn coordinator and the turn-and-slip indicator? The turn coordinator
indicates roll rate, rate of turn, and coordination; the turn-and-slip indicator indicates rate of turn and coordination.
When using a 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.
To track inbound on the 215 radial of a VOR station, the recommended procedure is to set the OBS to
035 degrees and make heading corrections toward the CDI needle.
(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 45 degrees outbound.
When the CDI needle is centered during an airborne VOR check, the omnibearing selector and the TO/FROM indicator should read
within 6 degrees of the selected radial.
Which statement is true about magnetic deviation of a compass? Deviation
varies for different heading of the same aircraft.
Which situation would result in reverse sensing of a VOR receiver?
Flying a heading that is reciprocal to the bearing selected on the OBS.
You are flying an aircraft equipped with an electronic flight display and the air data computer fails. What instrument is affected?
Airspeed indicator.
(Refer to Figure 17.) Which illustration indicates that the airplane will intercept the 060 radial at a 60 degree angle inbound, if the present heading is maintained?
6.
(Refer to Figure 53, area 4.) You plan to depart on a day VFR flight from the Firebaugh (F34) airport. What is the floor of controlled airspace over this airport?
700’ AGL.
