To BOAC
to achieve this but to be at 1900 at 5.2 from touchdown requires a rate of descent of almost 1300fpm
Probably I did not understand correctly
But I would like to point out humbly that:
With 120 knots to lose 1900 ft in 5.2 NM a variometer of a little more than 730 ft/min is needed, with 150 knots 760 ft/min.
