Just some interesting info gleaned from my new bedside reader.   "The Hurricane II Manual"

 

Section 2: Handling and flying notes for pilot.

 

 

Engine Limitations:

 

Max Take-Off :         RPM = 3000    Boost =   +12  Temp (Coolant/Oil) =   -/-

 

Max climbing (1Hr): RPM = 2850     Boost =   +9   Temp (Coolant/Oil) = 125/90

 

Max Rich Cont.  :     RPM = 2650     Boost =   +7   Temp (Coolant/Oil) = 105/90

 

Max Weak Cont:      RPM = 2650     Boost =   +4   Temp (Coolant/Oil) = 105/90

 

Combat (5min) :       RPM = 3000     Boost =   +16   Temp (Coolant/Oil) = 135/105

 

 

Oil Pressure (lb/sq.in.):    Normal = 60-80  Minimum = 45

 

Min Temp for Take-Off (deg C):  Oil = 15   Coolant = 60

 

Fuel Pressure (lb/sq.in.) = 8-10

 

Maximum speeds:  (MPH IAS)

 

Diving = 390    Undercarriage down = 120    Flaps down = 120

 

Climbing speeds:  (MPH IAS)

Maximum Rate                       Standard climb (all alts) = 155

up to 16,000 = 140         

at 21,000      = 135

at 26,000      = 130

at 31,000      = 125

 

 

Economy

 

Climb:     RPM = 2850     Boost =   +9   (Recommended Max rate speeds)

 

Cruising: RPM = 1800-2000   Boost <= +4   (MPH IAS = 160)

 

 

 

Stall speeds (MPH IAS)

Gear/Flaps UP     = 80-90

Gear/Flaps Down = 60-75

 

Approach speeds (MPH IAS)

Engine assisted = 95  (Flaps up 105)

Glide                 = 105 (Flaps up 115)
