Use of runway exits
Hello All,
I am a long-time reader of Pprune, but this will be my first contribution.
I am currently involved in analysing runway exit and in particular RET locations for a runway.
I would like to get the pilot's perspective on the subject, especially for Code C aircraft, and in particular on these issues:
1) At what speed can you feasibily turn off into a 90 degree exit? What parameters of the exit impact on the exit speed, the width, the length, markings, knowledge of the airfield, visibility?
2) If a runway has a RET that is designed to handle aircraft at speeds up to 30 knots, will you actually endevour to use it at that speed? What factors affect your exit speed on a RET?
3) And this is particularly for A320/B737 pilots, how likely are you to be able to use a 30 knot RET located at 1500m from the threshold. I understand this is a very vague question, since there are so many factors that affect your braking performance, but some kind of general feeling on the matter would be very much appreciated, perhaps based on your experience at airports you fly to.
Thanks in advance for any useful info.
