Squawk 7000,
It's all very well saying "go around and try again" but you can still scrape a tail if you carry-out the standard go-around at low level (below 50 feet) due to the high rate of descent associated with a steep (5.5˚) approach.
A scrape will occur at 6.9˚ nose-up on an RJ100 (8.3˚ nose-up on the RJ85) with the oleos fully compressed. Bearing in mind, at 50 feet the rate of descent will still be in the order of 850 feet/min. As a result, initial LCY qualification should include a low-level go-around below 50 feet. When I flew the RJ100 we limited the low-level go-around to an initial attitude of 5˚ nose-up instead of the normal attitude of 10˚ nose-up.
As you say, there's little margin for error with an RJ100 at LCY.
