SRA’s? there is a blast from the past.......sadly fewer and fewer civil ATC units are able to offer an SRA or PAR today HD.
I understand that the cost in training and currency is considered prohibitive, considering the rise of GPS/ RNAV etc and the decreasing need for such a service at civil airfields.
Pity really, they were the ultimate in co-ordination & co-operation long before CRM was even considered….
machlimter99 - the point being that you shouldn't be full deflection in the first place. If you are getting out of tolerances you G/A and try again.
Normally should the ILS for some reason stop radiating you will at that precise moment be on the LOC and G/S and therefore are going around from a known position. Hopefully you will either have suitable Nav aids or GPS feed to an FMC to fly the required profile. If not, then realistically you will either receive positive radar control from ATC, or if that is also not available you fly a combination of old fashion dead reckoning.
Do take note that when an approach is being constructed all of this is considered....
