Certified Flyers II
Duchess Multi-Engine Study Guide
Recommended cruise power setting is 24” MP, 2300rpm.
DESCENT
Plan your descent well in advanced to avoid extended flights at power settings below
20” (plan 5 miles for every 1000’ to be lost for en route descent)
Verify cowl flaps are closed, complete descent checklist, and monitor engine gauges for
safe engine temperatures
TRAFFIC PATTERN ENTRY AND NORMAL LANDINGS
1. Brief before landing and landing checklist before entering the traffic pattern
2. Enter the pattern at or below 120 KIAS, apx 17” MP, 2300 PRM
3. Downwind abeam midfield extend gear and verify 3 green (no red), check visually
4. Downwind abeam landing aim point reduce power to apx 15”, extend flaps 10, pitch for
100 KIAS (begin descent apx 500 fpm)
5. GUMPS check
Gas (fuel selectors full forward, aux pumps on), Undercarriage (Verify gear down,
3 green and visual check), Mixture Full Rich, Prop (High RPM; Must be below 100
KAIS), Seat Belts
The GUMPS check is a backup before landing checklist and must be
demonstrated to insure pilots are familiar with its use when flying light complex
aircraft
6. Turn base, extend flaps 20, pitch for 90kts, GUMPS check
7. Turn final, extend full flaps, GUMPS check, maintain 85 KIAS (blue line) until short final—
maintain constant power, airspeed, and angle of attack
Announce “Blueline”/ “GUMPS”
At 400’ AGL announce “Gear Down, Stabilized”; if not stabilized at any point,
commence go-around before descending further
8. Reduce power gradually as you cross the threshold at your reference speed and power
to idle as you begin landing flare
AFTER LANDING
1. “3 C’s: Clear, Clean, Call”
a. Clear the runway—tail passed stop and hold short line
b. Clean—flaps up, strobes off, landing light off, transponder SBY
c. Call—ground control or announce clear on CTAF
2. Complete after landing checklist
