Bfe Approach And Landing

Front 1

Reference Speed (Vref)

Back 1

basis for computing approach and threshold speeds, 120% of stall speed at 50% flap setting with gear down

Front 2

Approach Speed (Vapp)

Back 2

equal to Vref plus adjustments for flap setting and wind effect

Front 3

Threshold Speed (Vth)

Back 3

speed at 50' height which equals Vref plus adjustments for flap setting and wind gusts

Front 4

Approach and Threshold Speeds (Abnormal Configuration)

Back 4

adjustments to Vapp and Vth based on the specific A/C malfunction (Vapp = flap setting, 1/2 headwind, wind gust, abnormal configuration. Vth = flap setting, wind gusts, abnormal configuration)

Front 5

Air Minimum Control Speeds (Vmca)

Back 5

min speed which control is maintained with engine failure at go-around thrust setting while maintaining a straight flight path and not more than 5 degrees AOB w/ max rudder available. (based on GW less than 234,000 lbs., rudder boost on, flaps 50)

Front 6

Flare Distance

Back 6

distance covered from the 50' height point to touchdown

Front 7

Landing Ground Roll

Back 7

distance from the touchdown point to stopping point

Front 8

Landing Distance

Back 8

distance from 50' height point to the stopping point.
