Radio failure IFR


I was just reading again the general procedures to be completed in case of radio failure.

I was reading: "Proceed according to the current flight plan route to the appropriate designated navigation aid or fix serving the destination aerodrome and, when required to ensure compliance with 5), hold over this aid or fix until commencement of descent".

What i find confusing is the term: "the appropriate designated navigation aid or fix serving the destination aerodrome".

What do they mean with that? Is that a point in final? The IAF, which is not neccesarily in final?

Who can explain a bit?

I regard to be the IAF or designated 'clearance limit' of the STAR. I believe you would hold here until the expected approach time (if an estimate had been previously received) or as close to the estimated time of arrival. Also remember to set 7600 in the transponder (As Im sure you would).

Not that simple, I had one IFR at night AND the NAV aids failed! I used my handheld GPS and my phone to get down.

Hi Everybody.

In my modest oppinion,

Normaly a STAR takes about 15 minutes. And, normaly also the STAR begins at the last point that you can see in your current FPN (the last point may be: VOR or Waypoint.) This point, might be your IAF or not, it depends on the airspace/terminal where you are flying.

Keep in mind the following,

Commence descent at the estimated time of arrival ETA
Complete a normal instrument approach procedure and
Land within 30 min. after the ETA.

So, your point, that point may be far away from the aerport and you have 30 min. from there, a long time to complete what you read above,

in my modest oppinion

"the appropriate designated navigation aid or fix serving the destination aerodrome"
In the Jepp Supplement go to State peculiarity and you'll find a designed radio aid for almost all the airport. If your destination is not included in that list, IAF has to be considered.

Another aspect that's good for debate is when to start your descent. Do you fly to your Navaid/IAF/VOR at FL3XX and then shuttle-descend your way down to a sensible level to commence your approach? (This is the literal interpretation of the procedure) or do you start your descend as per normal arriving at a normal level at the IAF. I suggest option two since you are expected to fly your filed flight plan - barring any re-clearances you may have received - which most of the time includes a STAR which may have AT or AT OR BELOW altitude restrictions which require you to start descending earlier.

Any thoughts welcome

Excuse me Brie to digress slightly.

Does anyone know the procedure in case of radio failure flying RVSM.?

You would also need to consult the Jeppy Text Manual for any country specific procedures or your company equivalent. The procedure to be adopted will also depend on which stage of flight you are in eg: missed approach, enroute etc. By following these procedures you will give a heads up to the radar controller to clear the airspace around you and avoid any surprises in case your transponder went down as well and he wasn't able to see your 7600 squawk.
