Chapter 10: TCAS & GPS Flashcards
how does TCAS work?
communication between all aircraft with transponder > takes in information > predicts whether collision will occur
what frequency does TCAS work on
to aircrafts: 1030 MHz
reply: 1090 MHz
what infomation does TCAS take in?
bearing, altitude, range
what is the minimum range of TCAS?
40 nautical miles
what is the range and bearing accuracy of the antenna for TCAS?
range: 1/125 nm
bearing: 3 degrees
antennas can operate at temperature and airspeeds at?
temperature: -60degC - 100degC
airspeed: 600 knots
what does a open white diamond mean on TCAS?
non threat traffic - > 6 nm in range, 1200ft vertically apart
what does a solid white diamond mean on TCAS?
proximate traffic: within 6nm, with relative altitude notation
what does a yellow circle mean on TCAS?
potential hazardous
what does a red sqaure mean on TCAS?
resolution advisory - after potential hazardous if assessed to be actual threat
TCAS standard number for rate of climb/descent
500 ft per minute
elements of human machine interface are?
1) plan position display of traffi and threat
2) aural prompts for required action
3) display of required avoidance manoeuvre
what does GPS consist of?
1) space segment
2) control segment
3) user segment
what does the control segment of the GPS do?
monitors satellites, updates orbit parameters and clock, provide correction signals for ground
what is satellite clock error?
minor inaccuracies in synchronising satellite atomic clocks
