Advantages and Limitation of Map Reading

Advantages and Limitation of Map
Reading
Advantages
• The best means of checking dead reckoning
• No fix is more precise than a positive
identification of an accurately mapped landmark.
Limitation
• It cannot be used when the ground is obscured
by clouds or when flying over water
• Landmarks cannot always be readily identified
on a chart such as at night or if the chart is
incomplete or inaccurate.

Where can the VOT frequency for a particular airport be found?
A-On the IAP Chart and in the Airport/Facility Directory
B-Only in the Airport/Facility Directory
C-In the Airport/Facility Directory and on the A/G Voice
Communication Panel of the en route Low Altitude Chart
Where does the DME indicator have the greatest error between
ground distance to the VORTAC and displayed distance?
A-High altitude far from the VORTAC
B-High altitude close to VORTAC
C-Low altitude far from the VORTAC
How should a pilot determine when the DME is inoperative?
A-The airborne DME will always indicate “0” mileage
B-The airborne DME will “search”, but not “lock on”
C-The airborne DME will may appear normal, but there will be no
code tone
Which DME indication should you receive when you are directly over
a VORTAC site approximately 6,000 feet AGL?
A-0
B-1
C-1.3
To minimize DME slant range error, how far from the facility should
you be to consider the reading as accurate?
A-Two miles or more for each 1,000 feet of altitude above facility
B-One or mor miles for each 1,000 feet of altitude above facility
C-No specific distance is specified since the reception is line-of-sight
When making an airborne an VOR check, what is the maximum
allowable tolerance between the two indicators of dual VOR system
(units independent of each other except antenna)?
A-4° between the two indicated bearings of a VOR
B-Plus or minus 4° when set to identical radials of a VOR
C-6° between the two indicated radials of VOR
To minimize DME slant range error, how far from the facility should
you be to consider the reading as accurate?
A-Two miles or more for each 1,000 feet of altitude above facility
B-One or mor miles for each 1,000 feet of altitude above facility
C-No specific distance is specified since the reception is line-of-sight
What angular deviation from a VOR course centerline is represented
by a full-scale reflection of the CDI?
A-4°
B-5°
C-10°
When using VOR for navigation, which of the following should be
considered as station passage?
A-The first movement of the CDI as the airplane enters the zone of
confusion
B-The moment the TO-FROM indicator becomes blank
C-The first positive, complete reversal of the TO-FROM indicator
A VOR receiver with normal five-dot course sensitivity shows a threedot deflection at 30 NM from station. The aircraft would be displaced
approximately how far from the course centerline ?
A-2 NM
B-3 NM
C-5 NM
Determine the approximate time and distance to a station if a 5°
wingtip bearing change occurs in 1.5 minutes with a true airspeed of
95 knots
A-16 minutes and 14.3 NM Time In Minutes = Seconds / Degrees Change
B-18 minutes and 28.5 NM Distance = Minutes x TAS / Degrees Change
C-18 minutes and 33.0 NM
