[underlined] DRILL FOR USE OF FUEL TANKS [/underlined]
It is essential that all fuel tanks in the Lancaster aircraft are tested within a short time after take_off, to see that fuel can be drawn from either the No. 1 or No. 2 tanks. To ensure that this is done the appropriate drill as set out below is to be carried out on all flights.
A. For No. 1 and No. 2 tanks in use.
B. For No. 1, No. 2 and No. 3 tanks all full.
C. For No. 1, No. 2 and No. 3 tanks, and the long range fuel tanks all full.
A. [underlined] With No. 1 and No. 2 tanks in use. [/underlined]
(No. 1 and No. 2 tanks need not necessarily be full.
1. [underlined] Take_off [/underlined]
(i) Selector cock on No. 2 tanks.
(ii) No. 1 and No. 2 pulsometer pumps ON.
(iii) If petrol failure occurs on take_off, the Flight Engineer immediately turns the selector cocks to No. 1 tank.
2. [underlined] When Airborne [/underlined]
At 2,000 feet switch off pulsometer pumps.
3. [underlined] In Flight [/underlined]
(i) When 120 gallons of fuel have been used from each No. 2 tank, Flight Engineer informs Captain and changes selector cocks from No. 2 to No. 1 tanks. (This will be approximately one hour after take_off.)
(ii) Fly on No. 1 tanks for one hour. Check that fuel is being used from No. 1 tanks by observing petrol gauge readings.
(iii) After one hour Flight Engineer informs Captain that fuel systom [sic] is correct and changes back to No. 2 tanks.
(iv) Continue to draw fuel from No. 2 tanks until each No. 2 tank has approximately 100 to 150 gallons left by the fuel gauge readings, when the Flight Engineer informs Captain and changes selector cocks back to No. 1 tanks.
(v) The 100_150 gallons left in the No. 2 tanks is only to be used for emergency.
B. [underlined] No. 1, No. 2 and No. 3 tanks all full. [/underlined]
1. [underlined] Take_off [/underlined]
(i) Selector cock on No. 2 tanks.
(ii) No. 1 and No. 2 pulsometer pumps ON.
(iii) If petrol failure occurs on take_off, the Flight Engineer immediately turns the selector cocks to No. 1 tanks.
2. [underlined] When airborne [/underlined]
At 2,000 feet, switch off pulsometer pumps.
3. [underlined] In Flight [/underlined]
(i) When 120 gallons of fuel have been sued from each No. 2 tank, Flight Engineer informs Captain and changes selector cocks from No. 2 to No. 1 tanks. (This will be approximately one hour after take_off.)
[page break]
(ii) Flight Engineer then switches on No. 3 tanks pulsometer pumps, transfers fuel from No. 3 tanks to No. 2 tanks. Flight Engineer checks that fuel is being transferred by watching No. 3 and No. 2 tank gauges. Flight Engineer also checks fuel is being used from No. 1 tank by checking gauges.
(iii) When No. 3 tanks are empty, switches off No. 3 pulsometer pump switches and changes selector cock from No. 1 to No. 2 tanks. Continue to use No. 2 tanks until 100 to 150 gallons are left in each No. 2 tank. When Flight Engineer informs Captain and switches selector cocks back to No. 1 tanks for the remainder of the flight.
(iv) The 100 to 150 gallons left in No. 2 tanks are only to be used in emergency.
C. [underlined] No. 1, No. 2 and No. 3 tanks and the Long Range Fuel tanks. [/underlined]
1. [underlined] Take_off [/underlined]
(i) Selector cock on No. 2 tanks.
(ii) No. 1 and No. 2 pulsometer pumps ON.
(iii) All master fuel cocks on.
(iv) If petrol failure occurs on the take_off, the Flight Engineer immediately turns the selector cocks to No. 1 tank. Pilot makes immediate landing at his base after lightening the aircraft to 55,000 lbs.
2. [underlined] When Airborne [/underlined]
(i) At 2,000 feet switch off immersed fuel pumps.
(ii) After thirty minutes flight, change to No. 1 tanks.
(iii) When sufficient fuel has been sued from No. 1 tanks to equal the amount carried in the long range tanks (i.o., [sic] if the two tanks are fitted 400 gallons must be used from each No. 1; if one long range tank is fitted 200 gallons must be used from each No. 1 tank), then changes to No. 2 tanks.
(iv) Having changed to No. 2 tanks start pumping the contents of the long range tanks into the No. 1 tanks. The correct sequence of this is:-
(a) Turn on both long range fuel cocks situated behind the front spar.
(b) Switch on the pump switches and fuel contents gauges.
(c) When the pulsometer pumps are switched on the petrol immediately starts to flow into No. 1 tanks and it will take approximately 60 minutes to transfer the whole fuel load either the 400 or 800 gallons.
(d) During the pumping process a careful watch must be maintained on the fuel contents of gauges of No. 1 tanks to ensure that the petrol is being transferred evenly to both No. 1 tanks. In the event of one No. 1 tank being filled before the other the long range fuel tank cock to No. 1 tank that is filled first is to be turned off, thus allowing all the flow to go to the other No. 1 tank.
(v) While the fuel is being transferred from the long range tank of No. 1 tanks, the aircraft will be flying on its No. 2 tanks and as the fuel transfer will take at least 60 minutes the No. 2 tanks will be sufficiently emptied to allow for transfer of the No. 3 (Outer) tanks to the No. 2 tanks. Accordingly, as soon as the long range tanks are emptied the petrol is to be transferred in the normal manner from No. 3 to No. 2 tanks. This means that after the aircraft has been airborne from 5 to 5 1/2 hours the No. 1 tanks will be full and the No. 2 tanks will be topped up from the No. 3 tanks, i.e., after 5 1/2 hours the aircraft will have full No. 1 and No. 2 tanks.

[underlined] MARK VIII AUTO PILOT [/underlined]
[underlined] SEQUENCE OF OPERATIONS [/underlined]
1. [underlined] Immediately prior to take-off, [/underlined] check that the clutch lever is in the “IN” position.
(a) Move the stick fore and aft, and the ailerons left and right to extremities of travel to ensure clutches are engaged.
(b) With engines running, and 60 lbs. per square inch on the pressure gauge, check that the control surfaces are free in “SPIN” and “OUT” positions of control cock.
(c) Return control cock to “OUT”
(d) Switch on D.R. Compass.
2. [underlined] ENGAGING THE CONTROLS [/underlined]
(a) As soon as convenient, after the take-off, set the control cock to “SPIN”. [underlined] After not less than 5 minutes [/underlined] with the cock in this position, the auto pilot is ready for use.
(b) Set the pitch control to the desired pitch attitude of the aircraft.
(c) Trim aircraft, “hands and feet off” at the desired airspeed and course. [underlined] Rudder trim is most important. [/underlined]
(d) Set the pointer of the pilot’s repeater parallel with the grid or lubber line.
(e) Set the “Control Switch” to “Compass”.
(f) Move the control cock to “IN”.
If it is found that a first cutting in the stick kicks back, subsequent engagement may be accomplished more comfortably as follows:-
Whie [sic] in “SPIN” and ready to engage, trime [sic] “Hands off” as before, and then put the aircraft into a shallow drive, [sic] then then case the stick back so that it is further back than its normal trimmed position, and cut “IN” as the aircraft reaches level.
If the kick was at first forward, climb the aircraft slightly and then ease the stick forward past its normal trimmed position, and cut “IN” as the aircraft reaches level.
The above must involve slow and small manoeuvres only.
If the aircraft does not fly laterally level, adjust rudder trim.
If left wing low, trim on left rudder.
If right wing low, trim on right rudder.
If the trim is adjusted in low wing swerve, the low wing will be depressed further.
[underlined] GENERAL OPERATIONS [/underlined]
(a) [underlined] Course-Changing, Slow [/underlined] Small changes of course may be made with the control switch at “Compass”, by resetting the pointer of the pilot’s repeaters.
(b) [underlined] Course-Changing, Fast [/underlined] Set the repeater pointer to the new course, and then turn the control switch to “jink”. A banked turn will develop. When the aircraft is about 10o short of the desired course, return the control switch to “compass”.
During a fast trim it will be necessary to keep the aircraft’s nose up, by adjustment of the pitch control, returning the control to its original setting as the turn comes off.
[underlined] CHANGE OF FORE AND AFT ATTITUDE [/underlined] The fore and aft attitude of the aircraft whilst under Auto Control [underlined] can only be altered by means of the pitch control. ON NO ACCOUNT IS THE MANUAL TRIMMER TO BE USED TO CHANGE ATTITUDE. [/underlined]
[underlined] IMMEDIATELY PRIOR TO LANDING: [/underlined]
a) Control Cock to “OUT”
b) Control Switch to “OFF”
[page break]
[underlined] VITAL PRECAUTIONS [/underlined]
1. Do not forget to check that slutches are engaged [underlined] before [/underlined] take-off.
2. Do not forget to allow 5 minutes in “SPIN”.
3. Do not disengage clutches in the air.
