GPS approaches are designed for you to fall back to LNAV if a 'higher' precision option like LPV fails during the approach. Just like going from ILS to localizer only if the glideslope fails. The Instrument Procedure Handbook p. 4-26 says: Flying a WAAS LPV approach requires an aircraft with WAAS-LPV avionics. If for some reason the WAAS service becomes ...

will the GPS get me closer to the centerline, or the VOR receiver? GPS is usually more precise than VOR. Even when selective availability was used this was true, and that program hasn't been in effect since 2000. The GPS will also have approximately the same error along the entire airway. The VOR's error will increase with distance from the VOR station. ...

Short answer: there seems to be no general plan to replace airways with Q and T routes. The FAA originally proposed replacing them, but the final rule doesn't include it. You can review the source rulemaking documents in the Federal Register and it looks like the idea of replacing (or retaining) airways seems to have been discarded, possibly in response to ...

The X in a flag for a intersection, waypoint or fix regardless of if it is a NavAid means there is a Minimum Crossing Altitude. An MCA present means you must be at or above a certain altitude when passing over the fix in the direction specified. This would provide obstacle clearance for that particular Victor airway. The MCA usually indicates a transition ...

It means that no Procedure Turn is required/expected if arriving within the sector defined by the 297 and 020 radials (inclusive) of DBL. The grey bars are a way of denoting the boundaries of the No PT sector (the entire pie section between the radials) without obstructing too much of the other details. That's why the bars are bordered on the north side of ...

Here is the final answer handed down directly from the Garmin technical support department. After a conversation with one of their aviation technicians, he told me that the error seems to be in their database. The same discrepancy (a track of 159 instead of 157) appeared whenever he reviewed the KRNT 16 RNAV Y approach from his end. He even rolled back the ...

When flying VFR from a Class D airport, there is no need to contact clearance delivery to practice IFR approaches. You may, on the other hand, have to call clearance delivery if that is the local procedure for all departures at that airport. This is not very common at a Class D airport. If a clearance is necessary for VFR flights at a Class D airport, most ...

This is a terminology problem - and I think you're actually both right but you need to learn the terminology. Radials always radiate out from the VOR. You should absolutely always set the needle to the heading you intend to fly in order to avoid reverse sensing. However, if you're intending to "fly inbound on the 240 radial" then you're actually on ...

In Europe, like in most of the world, IFR enroute charts are published in ENR 6 of the national AIP, which can be found notably from Eurocontrol @IS online. Some countries publish these charts in sections ENR 3.x. Some countries like Spain even publish electronic charts. More details (route data tables) about IFR routes are published in the following ...

It's legal if you have a suitable and acceptable RNAV system as described by FAA Rules. Also realize that it is only RNAV capability that provides for 'direct routing' without recourse to DR - Dead Reckoning - or Radar assisted DR needed by traditional Radio Aid based navigation. When an RNAV system navigates to an out of service VOR, it is flying a computed ...

Your instructor is correct - using his method, means you do not have to do any reciprocal course/heading/plus/minus 180 calculations - instead you must remember "Radial 050 outbound" set the head (arrow/course) on 050. "Radial 160 inbound" set the tail on 160 which means the head/arrow/course will be on 340. It's evident that you have to ...

Your Questions: Why do SOHOW and USIRE exist? And in particular why do they both exist? Why do they exist: SOHOW and USIRE are published Waypoints on RNAV STARs into Gary, Ind., and Indianapolis, Ind., respectively. They exist and are published because they are part of the procedure being flown (as assigned by ATC). Why do they both exist: Even though they ...

A couple of years ago a black hole appeared over Austria (Vienna FIR—LOVV; except west Tirol which is very narrow and routes are still used in the neighbouring FIRs) where there are no routes any more and all routing is ad-hoc between fixes. It has since grown to cover Slovakia (Bratislava FIR—LZBB), Hungaria (Budapest FIR—LHCC), Slovenia (Ljubljana FIR—LJLA)...

Well, all of you (and, the instructor) are correct for using your own technique on the aircraft in which you are familiar. The technique can vary depending on your equipment. So let’s clear up a few things. You can not get reverse sensing with a properly working HSI (which the G500 should have). This is because the HSI should always orient the displayed ...

@Ralph J was on the right track with the hidden decimals behind the degrees. This should solve the mystery: You’ve probably noticed that GPS course guidance is often a degree or three different from the courses shown on the chart. The reason is the magnetic variation used by your GPS, the chart designer, and the VOR defining an airway may all be different. ...

I would expect to receive radar vectors to final if I was coming from the north into Decatur, IL. However, we do not plan on radar vectors when we flight plan because we could lose our ability to communicate with ATC. I would fly the victor airways to AXC. I might plan on coming in on the 029 radial (V191) to AXC. I am hoping for a clearance for the ...

RCTP - Taipei, Taiwan Airport AJENT SID - Standard Instrument Departure leading to the Navigation fix named AJENT MKG - fly to the MAGONG VOR Navigation beacon A1 - follow airway A1 ANPOG - until the fix named ANPOG R200 - follow airway R200 GLN - until the GUANLAN VOR Naviation beacon W22 - follow airway W22 IDUMA - until the fix named IDUMA IDUMA STAR - ...

Manual tuning is like the old style analogue radios with a dial or rolling switch for tuning, similar to old AM/FM radios in your car, etc. Old Automatic Direction Finder (ADF) systems still have a tuning knob that does the same thing. BFO stands for Beat Frequency Oscillator. There is a bit of electrickery going on, but basically, the ADF radio receiver ...
