VEJ, let me try:. .For an MD11, VMIN is the slowest speed the FMS will permit in manual operation (A/T off). There is a continuous FMS information on the airspeed indicator during all phases of flight, configuration, altitude, etc., and the pilot can recognize it when an amber band becomes visible on the speed tape. The amber foot means:
VMIN for TO mode: . .Slats Ext – 1.2 Vs. .Slats Ret – 1.25 Vs
VMIN for climb, cruise and descent – Clean configuration. VMIN above all engine acceleration altitude is:. .Low Speed (for Mach < 0.5) – 1.3 Vs or 1.2g to stickshaker, whichever is higher.. .High Speed (for Mach > or = 0.5) - 1.2g to buffet (FAA), or 1.3g to buffet (JAA/CAA).
VMIN for approach and landing - All Configurations:. .Gear dn - 1.3 Vs. .Gear up - 1.3 Vs or 1.2g to stickshaker, whichever is higher.
VMIN for G/A:. .The current airspeed at G/A initiation, or. .1.2 Vs for flaps > or = 31 deg., or. .1.3 Vs for falaps < 31 deg. for current configuration, whichever is higher.
Note: Minimum speed for A/T operation is amber foot plus 5 ktnots.
