180 KIAS to 6NM
Hi,
My base airport has recently started issuing this instruction on final. Whilst this is possible on our type with a reasonable headwind it’s trickier in light winds with at higher landing weights. On one occasion, the controller queried that we were maintaining the speed after I reduced the command speed on the MCP (our indicated airspeed had not changed).
As I see it, this is used to tighten up gaps in the landing sequence that are the result of wider vectors/poor speed control. As pilots, we can refuse any such speed instruction but it can be an invidious position to be in.
