I fly in a Metropolitan area and am right on the edge of a bigger airport boundary. When the weather gets bad I don't really feel comfortable shooting an approach to a towered airport plus we aren't allowed to file ifr. I put in some sequenced user waypoints and it tests out pretty great. Haven't done it in the soup yet. anyone else try this out? 

Troll.

Ignore all of the crap repliers! I fly quite often to a Colorado Ranch at night! The Boss arrives at the main Airport in his Private Jet then I fly the 44 miles to the Ranch!! There are numerous Mountains along the route and at the destination! Like you I manufactured a VFR GPS aprroach to safely get me into the Ranch! In ADDITION I Use ANVS-9 NVGs! Never had a problem!!

big difference between making a gps route that you will follow day or night VFR with or without goggles and being a troll who claims to have made a gps route intended to fly in crap weather.   

I bet you set the DH to Tree Fiddy

The military makes their own "practice approaches".  Going to the back of ships at night (not a CV), we practiced self contained surveillance approaches which consistently produced better MAP/DH alignment than the shipboard controllers did.  Wouldn't use it for a routine procedure but it's always nice to know there is that one last option. 

had an established prodcedure to recover aboard the ship during poor weather.  Worked very well.  As for making your own gps approach for use imc, only an idiot would do that.  The legal and liability issues say it is stupid.

i do wonder why who’s site attracts those who are either idiots or trolls

An ELVA works ok until you have zero comms and maybe even the ship DIW with significantly reduced vis.  Having an alternate when either ELVA didn't work sure is better than planned ditch.  Nothing unsafe or idiot about it.  You've got a radar or maybe even just data link, use it.  Especially if your familiar with an OD-58 or FPN-63. 

I used to fly up the river to Patterson airport and turn right where the highway crosses. It puts you right on final to the runway.  Worked good on break-day when the weather was "just above minimums".  Does that count as a precision approach?

why not just follow the purple line bro

It's just a flight plan

It's a "contact approach" if you have an ifr clearance.

He made his own instrument approach procedure to his beach-front helipad and died using it. Not saying the approach killed him- the attitude that he didn't need formal procedures killed him.

Actual mileage may vary

Although, I unfortunately have a feeling people actually do this.

When your GPS is not in approach mode (on an actual approach), the CDI sensitivity is 1nm. In approach mode it's .3nm - Big difference

Same goes for VOR to ILS

Numbers may vary.

Not sure.

It's been awhile since I looked that up.  And it's been about 23 years since I learnt it in Avionics class a muschools.

get back to me after you do it in the weather and are in the unemployment line

you code the waypoints to effect proper lateral precision?

Check the legalities reference the airspace you fly in.

You can build a straight in ILS in a 737 NG (using the FMS) and a couple of waypoints and VNAV.It is not legal for IFR but it will work VFR when the GS is out or there is no GS.
