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)
An aircraft equipped with distance measuring equipment, DME would experience the greatest slang range error when flying at
High altitude and short distance from the station
ADF night effect is caused when
Sky waves returning to the Earth interfere with ground waves
ADF night effect error is most pronounced with
High frequency station
NDB systems are maintained by NAV Canada to an accuracy of at least plus or -5° for an approach and plus or -10° for enroute navigation
ADF bearing accuracy can be affected by precipitation, static thunderstorm effect, and night effect in the same way which error is common to all three
Causes by the pairing pointer to fluctuate excessively
You’re heading is 300° and the fixed card ADF indicates a relative bearing off 170° you want to intercept and OB track of 270° at a 45° angle direction and heading would you turn to
225° and left
You have been cleared for an ILS approach to your destination airport as you scan the approach plate. You observe that the three letter identifier for the localizer begin with an I. what does signify
The localizer alignment is within 3° or less of the runway heading
The ILS localizer front core signal is considered to be violent and reliable, 35° eater side of the centreline auto of water distance from the transmitter
10 nautical mile
The normal valid and reliable signal coverage of a localizer back course either side of the course central line at a distance of 18 nautical mile from the transmitter is
10 degrees
