tail wheel, thanks for clarifying that.
As for Chocks Away, why do I (or anybody, for that matter) have to justify my presence and
very infrequent postings on this forum. If you work it out, it is less than 2 posts per month over the 8 & 1/2 years I've been here.
Maybe I should hand back my PPRuNe badge (yes, I really do have one!) and hang up my keyboard...
