If the 737 is like most other FMS installations you will find the approach will activate at the capture fix. It is typically the waypoint just before the FAF. If you were flying into KMEM RNAV RWY 36C the capture fix would be NESBT and the FAF would be GINIE. In the FMS that I use, the capture fix is typically loaded twice into the flightplan. Once from ...

I was taught the following rule of thumb for providing a final vector to final, in the USA, using the STARS radar system which (when using ADS-B inputs) has a one-second update time: Set the Predicted Track Line to 30 seconds. Vector the aircraft to a 90º base-to-final. When the PTL reaches the extended runway final, issue the Position-Turn-Altitude-...

Mode A/C Transponders were originally implemented because the best you could get from skin reflection radar was a slant range altitude that wasn't very accurate. The altitude that a mode A/C transponder transmits with when swept by a Secondary Surveillance Radar or that a Mode S transponder autonomously squits (transmits every 1/4 sec) is pressure altitude. ...

I'm no expert, but from what I gather the transponder has a direct connection to the altimeter pre-Kollsman window. Not sure how that's possible but it's something along those lines. Essentially the transponder reports your flight level to ATC no matter what— it always reports your altitude assuming an altimeter setting of 29.92. Then the radar system on the ...
