Jesper, an irritated mind might fail to use an opportunity to think about the issues. What is the link between a tail scrape (for what ever reason) and full length / intersection departure?
Heathrow Director, LHR may be special (IMHO exceptional - plaudits), but as you well realize the absence problems is not absence of risk. LHR risk management may have been able to ensure the highest standard of controllers and assistants, but not necessarily ensure the same for all of the visiting pilots.
Dash&thump, I also assume that you realize that an intersection departure on a non limiting runway is not the same issue as for one in limiting conditions. An intersection London HR might be OK, but even in your ‘Jumbalino’, an intersection departure at London CY might not be so sensible.
The point of post #41 was to encourage pilots/controllers to think about the decision to accept / reject an intersection departure and state (openly or to themselves) their justification. Many posts in this forum focus on the conclusions of thinking, whereas stating the justification could help others understand a point of view.
