Convair CV-340 & CV-440 Pilot's Handling Notes
***********************************************

SUMMARY.

The two 1700hp Pratt & Whitney R-2800-CB16 Double Wasp engines are carburetted and highly supercharged to give rated power up to 14500 feet. 2400hp is available for take off (at sea level) and for two minutes in case of emergency using water/methanol injection. METO power is 1800hp to 8,500 feet. The constant speed propellers can be feathered and have reverse pitch. Automixture control is provided, but may be overidden.

Maximum fuel load is 1730 US gallons. All fuel burn figures are indicative and will vary slightly with altitude. Adjust fuel and payload using the weight and balance schedule of aircraft.cfg

The landing gear is NOT approved for use from unpaved surfaces.

***************************************************************

HANDLING THE AIRCRAFT

****************************

Take Off (with water/meth injection):

APPLY BRAKES

MIXTURE - MANUAL FULL RICH

CARB HEAT - COLD

COWL FLAPS - MID

TRIM 15% full range NOSE UP

FLAP - STAGE 1

CALL for TOGA POWER (2400hp)

PROPS FULLY FINE

Slowly apply FULL THROTTLE

This will invoke water/meth injection giving 59.5 inches MAP

ROTATE at 105 KIAS (@ 47000lbs)

CAUTION - 4675 feet required with TOGA power in ISA @ MTOW @ SL

Establish positive rate of climb

GEAR UP

ACCELERATE > 130 KIAS @ <= 500 ft/min

CLIMB 300 feet AGL

FLAP - UP

CALL for METO Power (1800hp)

48 inches MAP

2600 RPM

ACCELERATE to 150 KIAS @ <= 500 ft/min

CALL for Climb power (1350hp)

***********************************

Max climb: (1500hp)

COWL FLAPS - MID

39 inches MAP

2400 RPM

150 KIAS

Check CHT < 232C

Plan 250 USG per hour

***********************************

Normal climb BELOW FL160: (1350hp)

COWL FLAPS - MID

36 inches MAP

2400 RPM

150 KIAS

Check CHT < 232C

Plan 225 USG per hour

****************************

Climb ABOVE FL160:

COWL FLAPS - MID

FULL THROTTLE

2400 RPM

145 KIAS

Check CHT < 232C

Plan 220 USG per hour

****************************

Max Cruise (FL150 and below):

CALL for max continuous power (1400hp)

COWL FLAPS - CLOSED

39 inches MAP

2300 RPM

Check CHT < 232C

Plan 230 USG per hour

Note - yields 254 KTAS at FL150 = max cruise

****************************

Fast Cruise (FL195 and below):

CALL for cruise power (1200hp)

COWL FLAPS - CLOSED

35 inches MAP

2300 RPM

Check CHT < 232C

Plan 200 USG per hour

Note - Design cruising level = FL180 = 247 KTAS = design cruise

****************************

Econ Cruise (FL135 and below):

CALL for economy cruise power (about 1100hp)

COWL FLAPS - CLOSED

30 inches MAP

2100 RPM

Check CHT < 232C

Plan 185 USG per hour

Note - yields 225 KTAS at FL120

****************************

Econ Cruise (FL140 to FL195):

CALL for economy cruise power (about 1100hp)

COWL FLAPS - CLOSED

31 inches MAP

2200 RPM

Check CHT < 232C

Plan 185 USG per hour

Note - yields 232 KTAS at FL150

****************************

ALL Cruise (FL210 and above):

CALL for high level cruise power

COWL FLAPS - CLOSED

FULL THROTTLE

2300 RPM

Check CHT < 232C

Plan 185 USG per hour

Note - yields 230 KTAS at FL220


****************************

High Blower METO FL145: (1700hp)

FULL THROTTLE

2500 RPM

****************************

Descent:

AUTOMIXTURE - ON

COWL FLAPS - CRACKED

MAINTAIN CRUISE IAS

MAINTAIN CRUISE RPM

REDUCE MAP in stages of 3 inches (per minute)

See CARB HEAT below

*When* MAP = 25 INCHES

2100 RPM

REDUCE TO 170 KIAS

*****************************

Holding:

FLAP - UP

CALL for endurance power (600hp)

COWL FLAPS - CRACKED

2100 RPM

Slowly REDUCE MAP

To obtain 140 KIAS

but MINIMUM 23 inches MAP for holding

Check CHT < 232C

Plan 100 USG per hour

****************************

Final Approach and Landing:

MIXTURE - RICH

COWL FLAPS - MID

2300 RPM

MAP - as required

REDUCE < 170 KIAS

GEAR - DOWN

FLAP - STAGE 1

LANDING LIGHTS - DEPLOY


REDUCE < 165 KIAS

FLAP - STAGE 2

LANDING LIGHTS - ON


REDUCE < 155 KIAS

FLAP - STAGE 3


REDUCE < 145 KIAS

SHORT LANDING ONLY - FLAP - STAGE 4


Cross AIRPORT BOUNDARY 98 KIAS (@ 46,000lbs)

FLARE and LAND

COWL FLAPS - FULL OPEN

AFTER NOSEWHEEL CONTACT

REVERSE PITCH

WHEEL BRAKES as required

CAUTION - 4500 feet required after full flap landing and max braking @ MLW @ SL

****************************

Baulked Landing:

CALL for EMERGENCY POWER

PROPS FULL FINE

FULL THROTTLE (invokes water/meth injection)

COWL FLAPS - CLOSED

ROTATE and CLIMB 105 KIAS

Clear of obstacle

GEAR - UP

ACCELERATE >130 KIAS

COWL FLAPS - MID

FLAPS - UP (by stages)

ACCELERATE 150 KIAS

****************************

Carb Heat:

When < 30 inches MAP with an OAT below 5C (40F)
use carb heat periodically to clear carburettor ice.
Continuous use of carb heat is not recommended.

****************************
