Another for 3Greens -
The final flap and speed reduction must be taken at 1500'ARTE.
- since 4D equates to 1410'ARTE, 'taking land flap and speed reduction' AT 1500'ARTE is no issue, unless you are saying you must be 'on speed' AT 1500'ARTE?
I still think you Nigels should ask one of your 'wunderkind' how you are
supposed to do it - and get the answer in writing
