Note that this panel is
a generic panel for all marks of Comet 4, 4B &
4C.
The normal cruise for a 4B was faster & the
speeds shown in the checks reflect that.
Normal cruise for a 4 & 4C is mach 0.74 |

|
| Fuel Crossfeeds |
OPEN |
 |
| Allows fuel to get from
all tanks to all engines. |
| |
|
Centre Fuel Pumps
(if fuel loaded) |
ON |
 |
The Comet had a strange
arrangement for the Centre tank, where it would
only feed the left side engines, unless the crossfeed
was open. Once in climb & cruise you want to
burn the centre tank off, leaving excess fuel in
the wings.
With all crossfeeds open & centre tank pumps
on, you can turn the wing tank pumps off if desired
& burn only from the centre tank.
Red lights will illuminate under each tank when
the levels are getting low. |

|
| Engine Synchronizer |
ON |
 |
The engine synchronizer
forces other engines to adopt the same RPM as the
nominated engine.
VC only, the 2D has the flaps gauge in this position.
This is no great use if you only have a single throttle
control on your yoke/stick.
There are three sync modes:-
All engines to Port Outer (engine 1)
All engines to Starboard Inner (engine 3)
Outer engines (1 & 4) to Port Outer (engine
1) |

|
| Cabin Pressure |
OK |
 |
The two readings on the
Cabin Pressure Differential & Cabin Altitude
gauges must remain outside the red sections.
Setting a higher 'Required Cabin Alt' will raise
the Cabin Alt and reduce the Cabin Pressure Differential.
High Cabin Alt is uncomfortable for the passengers,
but High Pressure Differential stresses the aircraft.
Try to roughly balance them out. |
| |
|
| Cabin Temperature |
OK |
 |
Make sure that the cabin
is at a reasonable temperature for the passengers.
If not, increase the required temperature with the
switch.
If there is still no raise in cabin temperature,
your air inlet temperatures also needs increasing. |
| |
|
| Fuel Balance |
OK |
 |
If one wing gets much
heavier than the other, or if either wing is carrying
less than the centre tank, the fuel needs balancing
out better.
Balance the tanks by burning fuel from the tank
that needs the fuel load reduced. Do this by switching
off the pumps of the other tanks. |
| |
|
| De-icing |
As Required |
 |
If temperatures are in
a range where ice could be a problem, de-ice should
be used.
Structural de-ice and engine de-ice is on here.
Pitot heater and fuel heaters are also included
in this check.
If icing conditions could be present and any of
the above systems is off, the checklist will show
a cross. |

| Altimeter |
1013 mbs |
 |
| At cruise altitudes,
the standard altimeter pressure setting of 1013
mbs (29.92 in hg) should have been set. |
