Section 2.3.2 Part B
Rev No: 01 Stichting Catalina PH-PBY
Page: 2 25 May, 2005
All actions related to the handling of the aircraft shall be made by the PNF upon command
of the PF. Before making the selection the PNF will convince himself that operating
limitations and flight procedures allow the configuration or power change; if not, he will
inform the PF accordingly. Commands of which completion requires some time (gear and
power selections), shall be repeated by the PNF and acknowledged as soon as the
desired position or action has been obtained or completed.
05 PUSH BACK/TOW PROCEDURES
At many airfields push-back procedures are in force and local regulations should be
checked to determine whether a push-back or towing will occur before or after engine
starting.
If a push-back/tow procedure occurs the following applies:
The Catalina is normally towed with its own special towbar that fits onto the axle of the
nose wheel. Before towing the aircraft in this manner, the scissors bolt must be removed.
This enables the nose wheel to caster beyond the maximum 30° limit. If the bolt is not
removed and the wheel is turned beyond the limit, damage results. It is the responsibility
of the captain to see that the scissors bolt is removed before towing and replaced before
taxiing.
The "Before Taxi" checklist must always be completed.
It is essential that a positive confirmation of a BRAKES ON/OFF request is obtained when
communicating with the ground engineer.
06 ENGINE STARTING
After start-up approval has been obtained by the PNF and the Before Starting Checklist
has been completed, the engines are started. Engine starting will be done according the
crew co-ordination procedure below.
The PF devotes his full attention to starting the engines and monitors the engine
parameters.
The PNF monitors the PF and pays attention to any possible hand signals from the ground
engineer.
It is good practice to motor the engine through at least twelve blades with the ignition
switches off before starting the engine. This enables the oil pump to supply oil to the
reduction gear area and at the same time it will disclose the presence of any oil in the
cylinders (Hydraulicing)
It is allowed to start the engines by use of scan flows before using the Checklists. This to
warm up the engine and use the time, while warming up the engines, for briefings and
checklists.
