I may have unintentionally misled you. These are “special” approaches and though they are published for the air carriers that are authorized to use them, they are not available to the general public. The one that springs to mind is the “Silver” approach into Reno, Nevada ILS Rwy 16R. The standard mins are set at 928’ AGL with no restrictions on the miss.
The Silver ILS goes down to 200’ AGL but there is an approximate 8% climb gradient required for the miss (straight out climb to 6,000 above the miss altitude). As I mentioned – one Performance Engineer said about the only twin jet that could make that single engine is an empty 757 on a cold day.
So air carriers provide a OEI procedure which goes straight for a couple of miles, then makes about a 220° turn around a nasty protuberance called “Rattlesnake Hill” then back over the north end of the field up a valley.
The OEI miss procedure flies over the same track provided for the OEI takeoff procedure for the same runway – as this is the least obstacle rich environment around. The same obstacle clearance criteria are used as the takeoff procedure except that the aircraft configuration is defined by the Approach Climb limitations of FAR 25.
I believe there are several of these types of approaches in Colorado (obviously the altitude is a major performance factor here) and I have been told that there are lots in South America but I cannot provide examples.
I suspect you and I are beyond quibbling over the word "attitude" so I'm not going to be drawn into that - we can just chalk it up to my poor writing skills.
Perhaps someone else who has examples can chime in. US, Australia, Asia?
Thanks for any info,
