How are rate of descent and AOA controlled on the
glideslope?
ANSWER: Rate of descent is controlled with power and AOA is
controlled with nose attitude.
(1) Make a level turn to final approach assigned heading using
standard rate turn (approximately 20 degree AOB)
(2) Reduce power (If necessary)
(3) Verify on-speed AOA against airspeed
(4) Adjust power, pitch, and trim to maintain hands off level flight and
on-speed AOA
(5) Extend speed brakes when controller states "on" glidepath to
establish desired rate of descent, (adjust power if necessary)
COMMON ERROR: Late slowing to on-speed AOA and slow to
trim.
(6) Make small VSI corrections by adjusting power for glidepath
while maintaining on-speed AOA
(7) Make small AOB corrections (10 degrees or less) for course
corrections on final
NOTE: A combination of power and nose attitude adjustments
will be required for a smooth and precise approach.
COMMON ERROR: Reversing control of nose attitude and
power.
COMMON ERROR: Using nose attitude to control glideslope.
