Stud 10 Flashcards
Which of the following statement is correct with the respect of operation GPS
It measures distance by precise timing of a radio, signal, transmitted from a satellite, the signal carrier data, which does closest satellite position of transmission and synchronizes the aircraft GPS systems clock.
GPS provides…
Position, heading, ground speed and altitude information.
How many GPS satellites are required to obtain a three dimensional position fix for an aircraft?
Four 4
Which of the following statements is true with the reference to rnav approaches with the lateral guidance only
Pilots using TSO-C 129/129a avionics should use the raim prediction feature to ensure that approach level raim will be available plus or minus 15 minutes of the ETA at the destination or alternate airport.
Without Raim capability on TSO-C 129/129a avionics the pirate of GPS equipped aircraft.
Will have no assurance of the accuracy of the GPS position.
An example of a ABAS system
RAIM AND FDE
How many invisible satellites are required for the FDE function to be available?
6
If the RAIM AVIONIC DETECT A SATELLITE MALFUNCTION THAT MAY LEAD TO A PRECISION DEVIATION OUT OF THE RNP AND P FOR THE CURRENT FIGHT PHASE THE avionic will
Alert the pilot and interrupt the navigation solution
If the FDE Avion detect a satellite malfunction that may lead to a precision deviation out of the RNP for the current phase, the avionic will
Detect which satellite is malfunctioning, and therefore excluded from the navigation solution
A RAIM avionic, may be used to fly NPA approaches down to LNAV minimums
The tolerance of published VOR airway radials is maintained by NAV Canada to within how many degrees
+- 3 degrees
VOr
It is a line of sight limited system, where obstacles can block VOR signals, and restrict the distance over which they can be received for a given altitude
VOr
A phase difference between two transmitted signals
Possible disadvantage of using VOR to navigate at high altitude
On occasion, station coverage areas overlap causing erroneous VOR readings.
DME the measurement of the time difference between the transmission of an aircraft interrogating signal, and the receipt of a matched pulse reply signal from a ground station(the two signals having different frequencies)
