Boeing 247D Pilot's Handling Notes
**********************************
SUMMARY.
The latest D model 247 has two 550hp Pratt & Whitney R-1340-S1H1-G Wasp engines which are geared, carburetted and supercharged to give rated power up to 8000 feet. Controllable pitch propellers have been introduced to reduce cabin noise and improve crusing efficiency at all altitudes. These new airscrews can be feathered and greatly increase safety following an engine failure.
Maximum and normal fuel load is 273 US gallons of which 70 gallons are to be retained as an IFR reserve and 3 gallons are unusable.
For passenger comfort operation above FL120 should be restricted to 30 minutes per flight.
This aircraft is fited with the optional Sperry autopilot.
EMERGENCY only push to full throttle and full fine
RELEASE BRAKES
YOKE - FULL FORWARD to raise tail
TAIL UP - reduce forward pressure
ROTATE at 70 KIAS
Establish positive rate of climb
GEAR UP
ACCELERATE 100 KIAS @ <= 500 ft/min
CALL for Climb Power
**********************************
Climb:
31 inches MAP
2100 rpm
105 KIAS (about 1100 VSI at max gross)
Plan 90 USG per hour
Mixture - Rich until above FL60
****************************
Max Cruise:
30 inches MAP
2000 rpm
Plan 75 USG per hour (440hp)
Mixture - lean as required
Note: Best cruise is full throttle / 2000 rpm at FL120 = 165 KTAS
****************************
Fast Cruise:
28 inches MAP
1900 rpm
Plan 65 USG per hour (400hp)
Mixture - lean as required
****************************
Econ Cruise:
25 inches MAP
1800 rpm
Plan 55 USG per hour (330hp)
Mixture - lean as required
****************************
Descent:
MIXTURE - RICH
AVOID shock cooling
REDUCE MAP in stages of max 3 inches (per minute)
MINIMUM 15 INCHES MAP
GEAR - may be extended as air brake < 155 KIAS
See CARB HEAT below
*****************************
Holding:
20 inches MAP
1800 rpm
Mixture - max safe leaning
Plan 40 USG per hour (250hp)
*****************************
Circuit - Approach and Landing:
Intermediate approach
MIXTURE - RICH
20 inches MAP
1900 rpm
Visual Circuit or established LOC
15 inches MAP
Props - fully fine
Prior to descent
*REDUCE TO 80 KIAS*
On descending
GEAR - DOWN
10 inches MAP
Cross THRESHOLD 70 KIAS
FLARE and LAND
< 50 KIAS
YOKE FULL AFT
TAILWHEEL CONTACT
WHEEL BRAKES as required
****************************
Baulked Landing:
CALL for EMERGENCY POWER
PROPS FULL FINE
FULL THROTTLE
Note: Gives 35.5 / 2200 = 550hp
ROTATE and CLIMB 65 KIAS
Clear of obstacle
GEAR - UP
ACCELERATE 105 KIAS
****************************
Carb Heat:
When < 25 inches MAP with an OAT below 5C (40F)
use carb heat periodically to clear carburettor ice.
Continuous use of carb heat is not recommended.
****************************
General:
AEROBATICS are PROHIBITED
NEVER EXCEED 191 KIAS
GEAR DOWN never exceed 155 KIAS
ROUGH AIR never exceed 155 KIAS
STALL 54 KIAS
