    I'm wondering by which method this sort of aircraft panel that enabling backlighting are made? What is the process? I've gathered they are acrylic but how is the gray paint selectively removed?

  • This video says the following:

    Here's my Tonson TS-3040C CNC making an EFIS panel for my flight simulator. For the lettering I am using a 0.4mm End Mill and for cutting out I'm using a 1mm End Mill. RPM is 10000 and movement is 300mm / Min. The material is Cast Acrylic which I have given one coat of black paint and two coats of grey paint.

    So that's at least one method, but there are probably more...

  • This page has some good information and a graphic, looks like the same as shown in the video Manfred posted. Clear plastic with an opaque layer that is engraved off, and lighted from beneath.

  • Provided an aircraft with a fly-by-wire system, there are basically two possible choices when it comes deciding how to let the pilots interface with it: rate control / attitude hold: a deflection... translate to a deflection of the surfaces, mimicking the "old" mechanical control setup. It is my understanding that this is the design choice of Boeing in its new aircrafts. I do not wish to discuss how Airbus and Boeing made their design decisions, but rather see if there has been performed a study on what interface is preferred by pilots, eventually differentiating among private/commercial pilots

  • Primary target: An aircraft not reporting mode-C, the only thing the controller has is the return on the radar. When a controller reports a primary target as traffic to other aircraft, the controller does not have the altitude of the target. Given this, I conclude that ATC radar does not have the altitude (angle-up) to the target, and only provides azimuth. So then without the altitude, how does the radar-system know where to put the target laterally on the screen? Example, a radar picks up a target that is 10 miles from the station. If the target is 0 AGL, the proper position would be 10

  • How does autobrake work? Gabriel Brito

    An autobrake is a type of automatic wheel-based hydraulic brake system for advanced airplanes. The autobrake is normally enabled during takeoff and landing procedures, when the aircraft's longitudinal deceleration system can be handled by the automated systems of the aircraft itself in order to keep the pilot free to perform other tasks - Wikipedia How does the aircraft "know" when is time to activate the autobrake systems on a rejected takeoff and landing? Does it apply full brake to all the aircraft's wheels? Is it really used by commercial jets?

  • What is the average range, accuracy, and update frequency of radar systems used to monitor airspace in the USA? I'm primarily interested in capabilities for tracking smaller general aviation aircraft without enhanced return data channels like ADS-B, etc. Please include sources, if possible. As an example, by looking at TRACON/ASR data exports (CDR), these systems appear to update an aircraft echo at about a 4.7 second frequency, give or take a few tenths. However, I not been been able to source or verify my findings or similar statements made by expert witnesses in litigation cases.

  • I was looking through my virtual radar logs one of the days and found this "glitchy" ADS-B behavior. I am almost 100% sure that this is not due to my antenna or setup since two independent different... is the "skew" at seemingly same angle? Is that anything? In light of MH370, does this happen often, how reliable is that GPS data?

  • This recent comment reports that: the IMU on new (plane) would localize the aircraft to within 3 feet after a cross-country flight, without any GPS input other than the starting location. I somewhat doubt about this statement, at least for an IMU based solely on inertial measurement: over the duration of a flight, I fear much more error accumulates. So what's the precision of a modern Inertial Measurement Unit over say the duration of a flight, and from what sources is that obtained? If some source (in particular, GPS) becomes unavailable, how does it degrade that accuracy?

Therefore, data from PC Windtemp must not be used for flight planning, aircraft dispatch, airborne flight
