ADF - Deactivation
I have just been told that Boeing is offering to deliver some new aircraft to us with ADF deactivated. I feel overjoyed as an AMT. I was just wondering if this is a new option or if your operators have had ADF deactivated on any of your fleets and how you feel about it?. Ours is B763F.

Suppose not for this fleet. Just one fleet type out of many so far. How Many NDB approaches are still there for a global carrier? Last one I was on was over a decade ago and it was Luanda Angola.
We had 777's delivered 5 years ago without ADF'S and Airbus delivered 4 years ago without ADF's.

In the days of anything above ETOPS 120 this shouldn't be an issue - all the classic ETOPS alternates will have something more than an NDB approach. That said I still prefer to have one or better two ADFs available to me

On an aircraft for a trunk route maybe but for all the Regionals & smaller mainliners ADFs are still required (try flying in northern Canada). Bombardier are still offering dual ADFs on their CSeries and the option's still part of the Rockwell Collins Vision Flight Deck.

Having no ADF's fitted doesn't effect ETOPS at all. In fact we are no longer allowed to do NDB approaches in my company.
RNAV, ILS VOR etc is all you need and has the world wide airports covered well enough without NDB's

Good thing we still make such a production of learning ADF procedures during initial IFR training and all flight testing
The last time I did a for real NDB in IMC conditions with only the ADF for track information (ie no GPS) was 1994. The next time I will be required to do a ADF approach will be in my next recurrent training and pilot proficiency flight test in March 2013

Almost no place has got an NDB approach nowadays, not the ones a 777 or an A32S would use anyway! 24th Feb 2013 10:51
That is not the first time that has happened to me and I am talking worldwide.

All 737s are RNAV equipped. Any airport accepting medium jets with only an NDB will surely have an RNAV approach by now? That's not a rhetorical question. Also, does anybody now fly an NDB or even a VOR without an FMC overlay using LNAV or the equivalent?
Exactly, if the Airport in question has an NDB approach most modern Aircraft can build any overlay and fly it in LNAV / VNAV.
If they don't have this capability then they probably still have an ADF receiver !

But in that case, you'd still need an ADF receiver for the raw data! We fly overlays too - occasionally we'll use HDG SEL but it's on the decrease as most of the time the map is pretty good, even in the non-GPS a/c.

Poland, non radar, many of the airports have both a VOR and an NDB at the field...
and with two separate procedures one based on the NDB one on the VOR, very handy if/when one of the two is down for MX...
there are many of the italian airports where this can be useful as well.
obviously we will be flying in L-NAV but until these places draw out some nice RNAV / RNP transitions for us to play with i still need to back up with raw data below MSA.

Last NDB I flew, we were asked by ATC if everything was alright. Needles were pointing where they should, but coastal refraction had us 30 degrees off track! Sooner they go, the better.
