If RAPCON(APPROACH facility) can not use radar..
« on: November 09, 2014, 01:48:48 AM »
if RAPCON(approach) can not use radar due to some problem(ex>electricity out, radar failure...) What does RAPCON do and be restricted their work?

I think this is called "NON RADAR SITUATION" and i wonder can they do air traffic control or not.

I learned Pilot use SID, STAR...etc which can operate under non radar in this situation, but if weather is not good, and pilot can not see outside(in cloud) i think just operating SID, STAR can be dangerous due to any traffic which do not contact control facility.

and i wonder what work  can RAPCON do under NON RADAR SITUATION.

if some vfr traffic suddenly contact RAPCON and request IFR clearance and radar vector due to weather, can RAPCON issue ifr clearance to vfr traffic? can RAPCON issue cleareance to fly some fix?(for example:C/S cleared to XXX(fix name), climb and maintain 9,000)

I want to know What work can RAPCON do in NON RADAR SITUATION.

Thanks..

Thank you for your answer about my question.

actually, i'm not pilot and i'm student who study ATC and not english native but i'am deeply moved by your kind answer in spite of my low quality english.

and as i wondered about this "if some vfr traffic suddenly contact RAPCON and request IFR clearance and radar vector due to weather, can RAPCON issue ifr clearance to vfr traffic?" in nonradar situation, What term should controller use?

you said "Cleared fix..." is radar vector, and if aircraft should go some fix to join airway, What term should controller use?

like "proceed fix"..?

i want to get your answer about my question, thanks.

Let me just reemphasize this difference about being cleared from present position.  I think that is where you are stuck.

If radar is available, having been radar identified and confirming Mode C altitude, I might get "cleared present position direct Bullion VOR, V32, somewhere".

If radar is not available, I can't get cleared from present position.  I would be cleared starting at Bullion and then along airways.  I have to be in VFR conditions responsible for my own navigation and terrain clearance until I get to Bullion VOR at an altitude high enough for obstacle clearance and navaid reception (the Minimum Enroute Altitude) and then my flight can continue under IFR along V32 to somewhere.

Just to clarify, you can be cleared to a fix that is not your destination in your IFR flight plan. This is called a clearance limit (and sometimes referred to as clearing short iirc), and if you do not receive further clearance you'll have to hold at that fix, it doesn't mean you have to go VFR from that point.
