PHS 9 — Takeoff7 steps
| 01 | Both ThrottlesADVANCE SMOOTHLY TO TAKEOFF POWERCAUTION: Full takeoff power is 1,200 HP per engine at 47 in. / 2,700 RPM. Maximum time at full takeoff power is 1 minute. Monitor engine instruments continuously during takeoff roll.NOTE: Advance both throttles together smoothly to achieve 47 inches manifold pressure at 2,700 RPM (full takeoff power / METO). Abrupt throttle application can cause torque-induced swerve. | |
| 02 | Directional Control (Rudder)MAINTAIN RUNWAY CENTERLINENOTE: Apply right rudder to counter left-turning tendency during takeoff roll. The tailwheel configuration requires active rudder inputs. Use differential braking if needed at low speed. | |
| 03 | Tailwheel (Lift Off)RAISE AT 60-70 MPHNOTE: Apply gentle back pressure to raise tailwheel off the ground at 60-70 MPH to achieve a 3-point level attitude for improved visibility and lift-off performance. | |
| 04 | Engine InstrumentsMONITOR - MP, RPM, CHT, OilWARNING: If any engine instrument exceeds limits during takeoff roll, abort if runway remains. Radial engines can fail quickly if overtempered or run with low oil pressure. | |
| 05 | Rotation / Lift-Off108 MPH (94 KIAS)NOTE: Aircraft lifts off at approximately 108 MPH (94 KIAS) in standard conditions. Allow aircraft to fly off naturally - do not force rotation. | |
| 06 | Initial Climb AttitudeESTABLISH POSITIVE RATE | |
| 07 | Landing GearRETRACT AFTER POSITIVE RATE CONFIRMEDCAUTION: Do not raise gear until positive rate of climb is established and runway cannot be used for abort. Single-engine climb performance is limited - keep gear down if in doubt.NOTE: Gear retraction is hydraulic. Confirm positive rate and runway behind before raising gear. Single-engine climb gear-up is marginal. |
PHS 10 — Climb13 steps

| 04 | Fuel Boost Pumps (Both)ONNOTE: On for descent, approach, and landing. | |
| 05 | Descent PowerREDUCE MP GRADUALLYNOTE: Reduce power gradually for descent. Avoid prolonged idle power on radial engines - they can cool too rapidly causing cylinder shock cooling. Maintain at least 15-20 inches MP during descent. | |
| 06 | Carburetor Heat (Both)AS REQUIREDNOTE: Apply carb heat before any significant power reduction to prevent carburetor icing. Check for RPM rise indicating ice was present. | |
| 07 | Cowl Flaps (Both)OPEN SLIGHTLY (descent cooling)NOTE: Partially open cowl flaps during power reduction to prevent shock cooling. Full power changes require full open. | |
| 08 | Mixtures (Both)AUTO RICH (below 5,000 ft)NOTE: Enrich mixtures as you descend below 5,000 ft to auto-rich. | |
| 09 | Oil Temperature (Both)MONITOR - Add power if cooling too rapidly | |
| 10 | Approach BriefingCOMPLETENOTE: Brief runway in use, approach procedure, decision altitude / MDA, missed approach procedure, and go-around power setting. |
PHS 13 — Before Landing11 steps
| 01 | Fuel Selectors (Both)MAIN TANKS | |
| 02 | Fuel Boost Pumps (Both)ON | |
| 03 | Mixtures (Both)AUTO RICH | |
| 04 | Propellers (Both)FULL FORWARD - HIGH RPMNOTE: Advance prop controls to full forward (high RPM) before landing. Ensures maximum power available for go-around immediately. | |
| 05 | Carburetor Heat (Both)AS REQUIREDNOTE: Apply carb heat on approach if icing conditions exist. Turn off before full power application for go-around. | |
| 06 | Landing GearDOWN AND LOCKED - Three greensCAUTION: If any green light fails to illuminate, verify gear visually if possible or declare emergency. Do not land without confirmed gear down.NOTE: Extend landing gear. Verify three green indicator lights. DC-3 is a tailwheel aircraft - main gear and tailwheel all three must show down and locked. | |
| 07 | Hydraulic Pressure500 PSI MINIMUMNOTE: Verify adequate hydraulic pressure for brakes. Hand pump backup available if pressure is low. | |
| 08 | FlapsAS REQUIRED - 1/4 TO 1/2 ON APPROACHNOTE: Apply partial flaps (1/4) on downwind or base leg. Apply additional flaps (1/2 or 3/4) when field is made. DC-3 hydraulic split-flap system. | |
| 09 | Cowl Flaps (Both)OPEN AS REQUIREDNOTE: Open cowl flaps for go-around readiness. Balance cooling need against drag. | |
| 10 | Seat Belt SignsON | |
| 11 | Approach Speed (Final)110-120 MPH (96-104 KIAS)NOTE: Normal approach speed with partial flaps. Cross the threshold at 85-90 MPH (74-78 KIAS). Single-engine final approach is flown at 110 MPH minimum. |
PHS 14 — Landing6 steps
| 01 | Final Approach Speed110-120 MPH (96-104 KIAS)NOTE: Maintain approach speed on final. Adjust power to control descent rate. Aim point is stable threshold crossing. | |
| 02 | Threshold Crossing Speed85-90 MPH (74-78 KIAS)NOTE: Cross runway threshold at 85-90 MPH with a stabilized approach. Reduce power to idle at threshold. | |
| 03 | Flare and TouchdownTAIL-LOW ATTITUDECAUTION: The DC-3 tailwheel design makes it susceptible to ground looping if directional control is lost after touchdown. Maintain firm rudder control throughout the rollout.NOTE: Flare to a tail-low attitude for touchdown. Three-point landing (mains and tailwheel simultaneously) or slightly tail-low main gear first. Avoid wheelbarrowing (nose-low on mains only). | |
| 04 | Directional Control (Rollout)MAINTAIN CENTERLINE WITH RUDDERNOTE: Active rudder inputs required throughout rollout. Use differential braking only to supplement rudder - avoid excessive braking. | |
| 05 | ThrottlesIDLE (at touchdown) | |
| 06 | BrakingSMOOTH AND PROGRESSIVENOTE: Apply brakes firmly but progressively. The tailwheel provides directional stability only when weight is on it. Avoid hard braking while tail is still in the air. |
PHS 15 — After Landing8 steps
| 01 | FlapsRETRACT (HYDRAULIC UP)NOTE: Retract flaps after clearing the runway to full up position. | |
| 02 | Carburetor Heat (Both)COLD (OFF) | |

| 04 | Seat Belt / No Smoking SignsOFF | |
| 05 | Fuel Boost Pumps (Both)OFF | |
| 06 | Cowl Flaps (Both)FULL OPEN (for cool-down) | |
| 07 | Engine Cool-DownIDLE 1,000-1,200 RPM - 2 MINUTESNOTE: Allow both engines to cool at idle for at least 2 minutes before shutdown. Radial engines require a cool-down period to prevent oil carbonization in the cylinders and bearing damage. | |
| 08 | Vacuum Gauge CheckCHECK during shutdown runNOTE: Monitor vacuum during shutdown. Should read normally until magnetos are cut. | |
| 09 | Magneto Cutout Check (10 RPM rise)VERIFY 10 RPM RISE at mixture cutoffCAUTION: If no RPM rise is observed when cutting mixture, the magnetos may still be live. Treat propeller as potentially HOT - do not touch. Notify maintenance.NOTE: When mixture is cut to idle cutoff, note a slight RPM rise just before engine stops. If no rise occurs, magneto grounding circuit may be failed - magnetos could be 'hot' even with switch off. | |
| 10 | Mixtures (Both)IDLE CUTOFF (to stop engines)NOTE: Cut mixtures to idle cutoff to stop both engines. This prevents fuel-fouled plugs and fire risk. | |
| 11 | Magneto Switches (Both)OFF (after engines stop) | |
