That was the only aircraft that did calibration of all the nav aids in south africa. Wonder how long its going to take them to get a new aircraft again.

I just don’t understand how accidents like this happen, assuming they were flying a standard departure or approach.... it’s not like they have to thread their way through a valley or something....how close would they come to those mountains following standard procedures?

One of the parts of the calibration process, is to fly arcs, through the centreline/ localiser at , at least 2 distances from the " station" . The arcs normally extend to approximately 2-4 nm on either side of the centreline/ localiser, and must also require a turn and reverse coarse arc. I stand under correction, 1 arc is at 13 DME/nm, which is very close to the arc, reportedly been flown, when this tragedy occurred.

At my present airport, the above mentioned arcs are flown at 6 nm and 15nm.

These arcs are flown for Every runway with an ILS and as far as I know a VOR approaches for which is published, in this case arcs for Rwy11 and 29.

It appears they were possibly flying the arc(s) for Rwy 11, thus west of airport. At bigger airports, with parallel rwys , this gets very complicated together with arriving and departing air traffic.

@SwissVan standard sids and stars always keep you safe.. But CAR doesn't follow that when doing calibration

 

 

 

Just speculation But i doubt it was pilot error... Well at least hope so. They where very good at doing this, so hope it was something with the aircraft that went wrong.

 

Its really crazy in the tower when we do calibration. Once arcs are done they do inbound outbound headings from vor/ils. Tower guys would sometimes have landing aircraft and CAR. Inbound opposite direction and only do a break off CAR With runway between

 

Its the only way to do it since it takes about 2/3 hrs to do both vor and ils

How da f.... do planes still fly into mountains these days. ( i assume that is what happened)

 

Even the small sling I am being trained on has a Garmin that yells at us when there is terrain in sight

 A big percentage of aircraft don't have the Garmin terrain equipment fitted. The terrain warning stuff is fairly new, much like your Sling is fairly newly built. Even then its not like synthetic vision, you just have yellow for <1000ft and red for <500ft. A heli for most instances cruises at 1000ft so yellow is the norm.

 

I have only flown 2 machines in past with the system built i. A rebuilt AS350 B3 Squirrel with a G500, fitted (rats at the instrument wiring while it was hangered in Africa for 3 years, G500 was cheaper then fixing the old stuff) the other is a 2018 EC130 T2 factory fresh.

 

Even the EC145 in CT doesn't have Garmin terrain fitted, we use a portable unit if you go fly in the pitch black at night. I used I portable unit most of my ops at the moment any way.

 

New Garmin integrated system fitted to a King Air just cost someone I know R1.8 mil

Would a plane that CAA uses all the time not have the latest and best?

Is the Garmin terrain product the only one on the market, I would have thought this would be a highly competitive market segment?

Speaking of the Garmin handheld devices. Do they still say something along the lines of don't use this device as the sole method of navigation?

 

I remember when I was an appy working on the Cessna piston engine planes we had one come in with 2 hand held devices attached to the dashboard. When we asked the pilot why he said the device tells you not to use it as the only device so now he has 2. :wacko:  :huh:

Unlikely it would have the latest and greatest

But I would be surprised if it did not have some sort of TAWS (terrain awareness and warning system)

 

It’s an old donkey, press reporting it was 33 years old which I can agree with, if not older as I remember it from last century when my old man used to work near the CAA’s hangar and it was my play ground.....

sounds like something my pilot brother in law would say
