 Minimum control speed during landing approach
: VMCL (FAR-JAR § 25.149)
With the aeroplane in the most critical configuration for
approach and landing, it is the calibrated airspeed, at which,
when the critical engine is made inoperative, and operating
engine(s) developing TOGA thrust, it is possible to maintain
the control of the aeroplane and maintain straight flight with an
angle of bank of not more than 5°.
(VMCL is also determined with 2 engines inoperative for three -
engined and four-engined aeroplanes.)
