Cross-country Flight Planning Flashcards
What are the tree common ways to navigate
Pilotage by reference to visible landmarks
Dead reckoning by computing direction and distance from a known position
Radio navigation by using radio aids
What types of aeronautical charts are available for use in VFR navigation
sectional charts - visual navigation for slow to medium speed A/C. 1” = 6.86 NM. Revised every 6 months
VFR terminal area charts - Depict the class B airspace. Similar to sectional charts but with more detail. 1” = 3.43 NM revised every 6 months
VFR Flyway Planning Charts - Printed on the reverse side of a TAC chart. Show flight paths and alt. recommended to bypass high traffic areas
Are EFB approved for use as a replacement for paper reference material, POH and supplements, charts etc.
Yes, EFBs can be used during all phases of flight operations in lieu of paper. Recommended to have a secondary or backup source of information such as paper or another EFB device
What is an isogonic line
Broken magenta lines connect points of equal magnetic variation. They show the amount and direction of magnetic variation which from time to time may vary
What is magnetic variation
Variation is the angle between true north and magnetic north. Shown in E or W variation depending upon whether magnetic north is to the east or west of true north
How do you convert a true direction to a magnetic direction
Note variation shows by the nearest isogonic line
East is leasts - subtract
West is best - add
What are lines of latitude and longitued
Latitude - east to west parallel to equator measure distance from equator N or S
Longitude go N S and at a right angle to equator
What are lines of latitude and longitued
Latitude - east to west parallel to equator measure distance from equator N or S
Longitude go N S and at a right angle to equator
What is magnetic deviation
Due to magnetic influence within the A/C (radios, light etc) the compass is deflected from its normal reading.. This is called deviation. The value is found on the deviation card located in the A/C
Name several types of navigational aids
VOR - Very hight frequency omnidirectional Range
VORTAC - VHF omnidirectional range / tactical air navigation
DMS - Distance measuring equipment
RNAV - area navigation includes INS, VOR/DME and GPS
What is a VOR or VORTAc
Radio stations that project radial in all directions from the station. Each radio is donated by an outbound magnetic direction. Almost all VORs are VORTAC which provides the standard bearing information plus distance information to pilot with airplane that have DME
Within what frequency range do VORs operate
VHF 108 - 117.95 right below aviation comm frequencies
What is a VOR radial
Line of magnetic bearing extending form a VOR. Always identified by their direction from the station. Regardless of heading an A/C on the 360 radio will always be north of the station
How are VOR NAVAIDs classified
Terminal, Low, and high
What reception distances can be expected from the various class VOR
T - 12,000' and below 25 miles L - below 18K' 40 miles H - below 18K' 40 miles H - 14.5 - 17,999' 100 miles with in the lower 48 H - FL180 - FL450 130 miles H - Above FL450 100 miles
What limitations if any apply to VOR reception distance
VORs are subject to line of sight restrictions, and the range varies proportionally to the altitude of the receiving equipment
What are the different methods for checking the accuracy of VOR receiver equipment
VOT check +/- 4 degrees Ground check point within 4 degrees Airborne checkpoint within 6 degrees Dual VOR check 4 degrees between each selected radial over a known ground point within 6 degrees
What is DME
distance measuring equipment. used to measure in NM the slant range distance of an A/C from the DME NAVAID. A/C equipped with DME are provided with distance and GS. Operate on UFH 960 - 1215 MHz
Give a brief explanation of GPS
satellite based radio navigation system that broadcasts a signal used by receivers to determine a precise position anywhere in the world. Tracks multiple satellites to determine position
What are the three functional elements of GPS
space element - 30 satellites
control element - ground based GPS monitoring and control stations to ensure accuracy of satellites
user element - antennas and receiver processor on the A/C providing positioning, velocity, and precise timing
What are the different types of GPS receivers available
Fully integrated IFR/VFR to hand held devices. Pilots must understand the limitations of the receivers prior to using in flight
What is the purpose of RAIM
Receiver autonomous integrity monitoring is a self-monitoring function performed by a GPS receiver to ensure that adequate GPS signals are being received from the satellites at all times. GPS will alert pilot when signal is not good enough for navigation
Where can a pilot obtain RAIM availability information
Manufacturer supplied RAIM prediction tool
Service Availability Prediction tool from the FAA
FSS during preflight
If RAIM capability is lost in-flight can you continue to use GPS for navigation
Without RAIM a pilot cannot assure accuracy of the position. VFR only or hand held GPS do not have RAIM and will not alert the pilot of issues
