SRA s
For my sins I've done 1 milers on a 424 and a 430, 2 milers on watchman and a new digital.
As a talking ILS you couldn't beat the 424 as long as the aircraft followed the correct slope otherwise it fell out of the beam and had to be sent round for another go.
Usual routine was - standard SRA, standard with step downs, no compass no gyro, ncng with step downs and if that didn't work go somewhere else!!
Ah! Those were the days! I can still hear the whine of the frequency converter!!
