ASR/PAR/No Gyro

[Fred]

Hi All,

I've been trying to get clear in my head the differences between PAR, ASR, and No Gyro approaches. The way I understand it, if your nav equiptment goes down, atc can help via ASR's or PAR's (one is non-precision, one is precision). ASR's provide course/azimuth guidance, and PAR's give both azimuth and altitude quidance. If you lose your gyros, then a no-gyro approach is your best bet.

Does this sound about right? Can anyone add to this to help me understand? Thanks in advance.

Fred

Keep in mind that most ATC facilities may not be able to handle ASR and PAR approaches. It's been a while since I studied for the IR written, so I'm a little rusty. I'll let someone who has more of a clue answer in full. I do remember reading that one or the other is mainly a military approach. As far as the no-gyro, you can do that one in any controlled environment, just make sure you tell ATC that it's a no-gyro approach.

Just use the search function on the forum, it's right here. I wrote an article about it a little over a year ago, check thread above.
