interested in understanding what speed should be used during the final approach. recent flight into EGJJ on rnwy27 (BMI Baby 600) the fms indicated 126@30deg flap.. using this I ended up "sinking" along the last 1 mile of the flight with the Angle of attack approaching a full take off view?

 

added throttle to around 150 and this seemed to settle things down and enabled a safe landing.

 

Interested in hearing about the "correct" speed on this critical part of the flight.

 

thanks

90% of the time: VREF30 + 5 so in your case 126+5 = 131kias.

Pitch+Power=Performance

 

If you were at the correct speed of 131 (Vref+5), your AOA should have been fine. That's the pitch part. However, if you didn't have enough power, then you'd sink.

 

That's one way of looking at it, anyway.

 

You should have a power setting around 55-57% N1.

 

So, did you have the autothrottle on?

Sure you had your flaps set correct?

yep, flaps 30 fms indicated speed vref 125 but that was way to slow sinking feeling

Were you flying in the VC or 2D - 2D's always going to have a fairly wrong view angle.

Take a look here: http://scandinavian-va.eu/pages/flightops/descent.aspx

 

They explain it very well.

It's not the speed per say that caused the too high descent rate.

You needed to either trim up a tad, add a bit more power, or a

combination of both. In most cases, if the speed was on, and you needed to

trim up a tad to decrease the rate of descent, you will need to add a wee bit

of power to maintain the same speed after re-trimming.

Like one said, with normal winds, Vref+5 is the usual. If windy or gusty,

I'll usually bump up to Vref+10.

I did a flight to Okie City this morning.. Funky weather, with natural

fireworks going off in the area..

I landed fairly warm due the gusty and shifting winds. Was about Vref+10

until I was over the fence. That was a 700, and I was still well below 150 knots

even at Vref+10.. I think about 139-140 or so knots as I recall..
