ADF Holds - Anticipating inbound track to the fix

I don't think I would destroy the panel layout by installing a 1950s ADF.

The 1950s ADF complements the 1950s Lycosaurus very nicely.

A response from the EGBJ manager, authorised for posting here, regarding why there is an NDB in the GPS/RNAV missed approach:

I'm taking this up with DAP at present but its absolutely right. The approach (sic) back in 2003? was that there needed to be a terrestrial aid but I'm seeing if the policy has changed. Watch this space!

to understand why Gloucestershire uses the NDB in its missed approach.

Shoreham EGKA was forced to do the same thing.

The excuse, according to internet rumour is that if the GPS fails, you can go missed back to the NDB.

Can't really argue with that, can you?

It's a bit like arguing against CRB checks for schoolteachers...

Matspart3 has been here too, though he probably does not "live" here.

Thanks for all answers :)

(Did my IR PC this morning - NDB holding and approach + ILS Approach in 900 foot broken. With and without autopilot in a C172 G1000. Refreshing and fun :) )

I think EGMD (Lydd) ones don't need the NDB at all. Just had a look...

Thanks Peter ;)

Let's hope that more procedures adopt this... er... approach.

I will ask matspart3 next time I see him, to understand why Gloucestershire uses the NDB in its missed approach.

Unfortunately, there are no such approaches in the UK at the moment, to my knowledge.

Looks like the ADF will still be a bain of many people's IMC / IR training and validation then :-)

You would be suprised at how real-world a JAA IR revalidation flight can be - with the right sort of instructor i.e. one who flies for real.

You are very unlikely to be doing NDB holds and, if you are, unlikely to be doing them using anything other than the GPS.

What the IMCR reval is like I don't know because I get that signed off at the same time as the IR (and also get the PPL reval done then).

It's just the initial (IRT) which can have all this stuff, and you can't know what you will get.

Actually, PA, it's only required for non-precision approaches that are based on an NDB for the final or missed approach segments. So a pure RNAV approach (with an RNAV-based missed approach procedure) wouldn't require carriage of an ADF.

Unfortunately, there are no such approaches in the UK at the moment, to my knowledge.

I read the AIC and was very excited by all of the items that allowed exceptions to carrying on board ADF equipment. Then I read it must still be used for non precision approcaches. I wish that also had an exception if one was carrying the duly required GNS navigation system allowed for enroute and terminal interception procedures.

Thanks for that AIC, Rich.

Since the stupid EAD website uses the stupid variable URL tokens to make sure that all bookmarks expire after a while (why???) I have edited your post to add a more permanent place for it
