Catch up with a programme on 'Discovery' about the Challenger 604 bizjet. There's an excellent example of a PAR Talkdown towards the end.
It was filmed without my knowledge - it's me doing the talkdown!!

That is after the controller tells you "From now on do not acknowledge any instructions".

Basically it is the same as flying the ILS raw data, but the final controller is figuring out the headings and vertical corrections for you.

As long as you fly the headings correctly, and you don't have a controller under training :} it works very nicely .

In the Air Force, where this is a common type of approach, a good controller will tell you exactly when you are passing the threshold. You would have been visual with the runway 150 feet before offcourse :E

Told to me personally, by an FAA inspector ( a former USAAF Colonel), in the mid-1960's....

"When we operated C-54's during the Berlin Airlift, the GCA (PAR) approaches offered, allowed a nearly zero visibility landing...and I have made plenty where, after landing, I could not taxi, due to the reduced visibility'.

When I asked about the flare maneuver, he said...'when over the threshold, the radar controller mentioned "close the throttles and reduce the descent rate to zero."

Apparently it worked as advertised, as many aircraft did this type of radar approach.

In the dim and distant past
 

We operated into and out of RAF Northold, almost daily, (not Shell/ or NJE) and were offered practice PAR for controller training.

The game was afoot, our brief, from the SATCO, was to be good but not too good....(speed control ( lack of) being his request). The PAR was to 0/0. The controller asked out type, (wheels to radar blob distance). The controllers were all good, and placed us on the numbers every time.
We for our training, conducted SE.

In return we were able to sit in the Radar room drinking RAF issue tea and biscuits, watching the work load, and chat to the PAR guy.

Them were the days.

Also did one or two for real in RAF Little Rissington, in very bad WX, but both engines fully operational.

SRA
 

SRA were the norm at Farnborough until the ILS was operational a few years ago.

Luton on 09(?), with the offset CL.

Surveillance Radar Approach, or sometimes Element, were very very common in Europe.


Still are in CIS.


Now what about BC ILS........

Chevron: exact name of programme please, and out of interest which airport.????
