Basic Pre Flight Flow

Recommended order of how to start the aircraft:

Its very similar to my L-410 and the guide with the checklists mostly translate over. However there are a few things to consider:

Firstly, Test fire detection before starting the aircraft. This is done via a push button on the top of each panel.

Secondly, For power saving measures, the radio altimeters for landing gear control are DISABLED by default. Allow the engines to start so power generation is available, or select it on with the APU running. This will now allow you to retract and extend the gear. With the switch off, this feature is diasabled. Once landed, I recommend switch the Rad alt switch to off as soon as practical.

Thirdly Check your fuel via the fuel panel. The fuel feeds from the wing tanks to the engines, so if they are empty, the engines will NOT start and transfer will be required

Lastly, to Start the engines flick the master first and hold the starter until above 30RPS, If you start them individually like you would in real life, ensure the RPM is roughly the same per engine before Taxi.

Lights and such are as found in the L-410 guide, everything is labelled so it should be relatively easy to work out once you get going.

Ground Servicing Guide

My version of the An-140 has two ground servicing features.

Firstly the External Power Connection. This is located on Aircraft left under the nose. If you plug in a power source, ensure it also passes a constant ON signal or a signal indicating power is generating. This will turn on the Ext Power Indicator light in the cockpit.

Lastly, under each wing is a refuelling panel. This allows you to set a target fuel amount and then pump that rough target into the tanks. There is logic to prioritise the wing tanks before filling up the central tank. Some imbalance may occur so use of the fuel panel in the cockpit to balance things round as required is a good thing to do.

Alarms and what they mean

This aircraft is equipped with 3 main alarms.

HI-LO Alarm
The emergency Beacon has been activated

High pitch beeping
The parking brake is set and the thrust levers are beyond around 30%

Lower Pitch slow beeping
Engine or APU fire warning
