When "we" flew into Iraq and Afghanistan at the end of GWII, corkscrew climbs and descents became the order of the day. The purpose of those profiles was to stay within the airport boundary, minimising the risk of attracting SAM attention. They were always flown manually as the A/P is limited to around 25 degrees of bank, and we needed upwards of 45 to stay within the boundaries.
In the beginning we'd do very steep climbs and descents; as we usually departed IQ or AF empty, there was loads of performance to be had. It worked until the day Eric Genotte and his crew took a SAM hit to the left wing of an A300 climbing out of Saddam Intl. After that corkscrews became the standard.
The steep descents and climbs were also flown manually, for the same reason as the corkscrew.
