Instrument Flight
Constant Airspeed Climbs and Descents
Complete the landing checklist at this time.
Once you are stabilized at 150 KIAS, initiate a 20-degree AOB turn for 45 degrees of heading change, first
in one direction and then back to the original heading. When rolling into the turns, adjust pitch and power
as necessary to maintain airspeed and altitude.
At the finish of these turns, adjust nose attitude and power to maintain level flight at optimum AOA.
Perform a 10-degree AOB turn for 30 degrees of heading change and then make a 10-degree AOB turn
back to the original heading.
Extend the speed brakes and establish and maintain a 500-fpm descent for 1,000 ft. Using 10 percent of
your VSI as a lead point, adjust pitch and power for level flight at optimum AOA.
When you have the aircraft stabilized at optimum AOA in level flight, initiate a climb (missed approach)
back to your original altitude by advancing the throttle to MRT, retracting the speed brakes, and raising the
nose 10 degrees to establish a positive rate of climb. Once you can confirm a positive rate of climb on the
VSI and altitude trend indicator, raise the landing gear. At or above 140 KIAS, raise the flaps/slats. When
your airspeed reaches 200 KIAS, raise the nose to maintain this airspeed. Using 10 percent of VSI as a
lead point, reduce power to the slow cruise setting and adjust pitch for level flight at 200 KIAS at the
original altitude.
Finally, perform a level-speed change to return to normal cruise airspeed (250 KIAS).
The slow flight maneuver is nothing more than a series of basic maneuvers, linked into a continuous
sequence. Pay particular attention to executing smooth transitions from one element of the maneuver to
the next.
The following lists the elements comprising the slow flight maneuver, in the sequence of performance:
1. Perform level speed change from 250 to 200 KIAS
2. Execute level 30-degree AOB turn for 90 degrees of heading change
3. Configure aircraft for landing and stabilize airspeed at 150 KIAS
4. Perform level 20-degree AOB turn for 45 degrees heading change and reverse to original
heading
5. Slow to optimum AOA
6. Perform level 10-degree AOB turn for 30 degrees and reverse to original heading
7. Extend speed brakes and descend at 500 fpm for 1,000 ft with aircraft at optimum AOA
8. Establish level flight at optimum AOA
9. Advance throttle to MRT, retract speed brakes, initiate a climb, raise gear and flaps/slats, and
climb at 200 KIAS to original altitude
10. Establish level flight at slow cruise (200 KIAS)
11. Perform a level speed change from 200 to 250 KIAS
