[underlined] HALIFAX MK. III [/underlined]
[underlined] Starting & Running Up. [/underlined] Gills fully open.
Test for hydraulicing after 1 hr. stand on ground
after 4 hrs. stationary in air.
Do not prime until engine is turning.
Run at 800 revs. then 1000 - 1200 revs. for warming up. Turn head to wind.
Before ground checking: - cylinder temp. min. 1000 C.
oil temp. min. 150 C.
oil press. min. 60 lb [symbol] “
oil temp. max. 900 C.
cyl. temp. max. 2700 C.
Check R.P.M. lever at 2200 revs. 2800 revs & 8 1/4 boost. throttle back to just under +6lbs. boost. & check mags. limit 50 revs. drop. Throttle back to 1500 revs. & check blower, temporary loss of 30lbs. oil press.
Do not run in S gear above 1500 revs. below 5000ft. [underlined] Stopping. [/underlined] Run at 1000 revs. until cyl. temp. finishes dropping, open up to [deleted] 12 [/deleted] [inserted] 1800 revs. [/inserted] for few seconds then throttle back & cut.
[page break]
[underlined] Handling & Climbing. [/underlined]
Climb at 2400 revs. & E.C.B. (+2) M gear at [underlined] 155 [/underlined] I.A.S. when boost falls to +1 (about 12000 ft.) change to S gear. Climb to 16000 ft. then advance throttle to mid-way position & climb at [underlined] 145 [/underlined] I.A.S. to 22,000 ft. then bring throttle back to E.C.B. position & fly at [underlined] 160 [/underlined] I.A.S. with 2400 revs. After releasing bombs climb to 24,000 ft. at 2400 revs. E.C.B. 160 I.A.S.
When descending leave throttle at E.C.B. position and progressively reduce revs. (Change back to M gear about 12,000 ft.) where revs. are down to 16,00 start closing throttle progressively.
For cruising throttle should be always left at E.C.B. position.
In emergency increase revs. to 2800 & open throttle until highest possible boost pressure is obtained.
