Calm down FOK You're not an ex RAF navigator by any chance??

Every real pilot I have ever met flies with printed data for the primary airports involved, enroute, etc.

One problem is that one cannot print a plate for every airport one might drop into when the sh*t hits the fan, hence the discussion of electronic means of displaying this stuff.

Another one is that the wonderful printed airways charts are barely usable in the cockpit, due to size and the difficulty of finding countries, never mind anything smaller...

You will also find that there are few if any laws dictating the carriage of stuff in printed format... it is merely prudent to backup stuff which is electronic.

Calm down FOK
thanks IO540, obviously IMCr / IR a touchy subject to IR holders!?

Only to certain kinds of IR holders...

I have a CPL/IR and still think the IMCR was brilliant. In fact I learnt sod-all doing the IR. Hmmm, let me see, what exactly did I learn on the IR?

1) lost comms procedure

2) the separation between lateral and vertical clearances

Maybe there was something else but I can't remember it.

All the juicy relevant stuff one picks up from other pilots, and the internet.

Almost no modern IFR pilot flies without a GPS moving map today.
No so. Even the FMSs of larger aircraft fail as to the NDs every now and again. And many don't have the option of simultaneous map & ILS. And another reason for charts - the fall-back or Plan B. As for the presentation of the chart, it doesn't really matter although a well put together electronic map bag would probably be far superior to printed charts. Just so long as it is up to date. When I had a PPL too many people baulked at buying half mil. chart updates or three year old Pooley's Guides. If they carried more than a photocopy of a single approach chart it would be a miracle. But the same people would go out of their way to have an "unofficial letdown" using Capital Radio and a stopwatch.

And if you are licensed to fly in the moo, a few (or even many) vectors shouldn't cause you to lose SA. Because one of the jobs of the charts is to help you with SA and help you orientate yourself. After all, there has been a few people vectored the wrong way for intercepts or even into high ground. No chart, no ground miss.

Approach plates

Because you would fail your I/R (or IMC rating) renewal if you don't use one? And it's the best way to be situationally aware whether you get vectors or not.
There are still plenty of airfields in France where radar isn't available (particularly at lunchtime) and a procedural approach is the only way to intercept.

Who is suggesting flying an IAP without having the plate?

The debate was vectors v. full-procedural.

It is true that, in an emergency, to fly an ILS all you need is to know the ILS frequency and get a vector to the localiser...

...or activate the approach in your Garmin glass cockpit, then everything is set up for you

I'm calm!!!

Since gaining my IR and flying for a living I remember how little I really knew with a PPL/Night/IMC.

So having spent years having SOPs drummed into me - and flying airliners with no GPS only the instruments you'd expect in an older twin - it goes against the grain when people ask questions which infer there is an option regarding the use of approach plates.

I once ended up diverting to Shannon and finding that someone had removed all the Shannon plates bar an NBD approach from the other end. We were already tired and to find, at the end of a cold foggy night, that there were no plates either was almost the final straw.

Yes, radar vectors to an ILS are child's play, but when things go wrong ...

I'm a ppl with an IMC rating.
When flying I have ALL of the approach plates. I sometimes fly the procedure for practice (especially NDB) and occasionaly you might find that the ILS is unservicable for some reason. I flew in to Filton once, the ILS was out so did a NDB/DME procedure.
Vectored ILS is easy but I alwasy have navaids tuned to build up a picture of where I am even if it not part of the ILS. So for exanple if tehre is a NDB on the airfield, and you have the DME from the ILS disaplyed, you've got a pretty good idea of where you.
personally really like instrument flying as I like mental challenge of it.

As someone else pointed out, the procedure is sometime flowing if coming in from the oterh side of the approach, say you are flying eastwards to wards manston and its a westerly wind, its easy enough to flying to the IAF (the NDB) and fly outbound and then turn to intercept the localiser. Easy for ATC as well I'd have thought.

Thats my two peneth
