dynamics and it is no-longer required to be switched on before take-off, though it could

form part of your check-list procedure. Dynamics features are controlled by the difficulty

level set by the heater rotary and those features applicable to the setting are active all of

the time.

11. Pitot Heat - This switch is used to energise the electrical heater element in the pitot tube

on the nose of the aircraft. The pitot tube may become iced up in flight during cold and wet

conditions and cease to function. After application, the pitot tube may take several

seconds before becoming free of ice and resuming normal operation.

Pilot Information: When the pitot tube is iced up the airspeed indicator will cease to

function and the reading will likely freeze at its current value. If the pilot notices that during

a perceived change in airspeed the gauge reading remains fixed, he should apply pitot heat

and continue to monitor the airspeed gauge to ensure that it returns to normal operation

within a few seconds. During this period the pilot should maintain reasonably straight and

level flight in order to avoid potentially hazardous flight conditions unawares.

12. Avionics switch - This switch controls the electrical power to the centre pedestal’s radio

equipment, including VHF radio, navigation radio and transponder.

Pilot Information: You will not be able to communicate with FSX’s air traffic control

stations if this switch is off or if electrical power has failed.

13. Master Battery switch - This switch isolates the aircraft’s battery from the main electrical

bus. Unless the engine is running and the generator functioning, all electrical power will be

lost if this switch is in the off position. Whilst on, the battery will slowly drain according to

the loading applied to it by any electrical systems that are functioning if the generator is not

functioning. If the battery voltage drops too low, then there may not be enough power

within it to start the engine. In this instance, selecting any option within the servicing dialog

will also recharge the battery.

Hint: Re-loading the aircraft or saved flight will also cause the battery to be recharged, and

unlike servicing, will not cost you. (See the “Servicing and Costings” section for details.)

14. Generator switch - This switch turns the generator on. The generator and starter motor

are one and the same. When operating as a starter motor, it takes electrical power from

the main bus and turns the shaft upon which the compressor turbine is mounted. When

the engine is running it generates electricity that will charge the battery, providing the

Generator Field CB is in and the starter/generator itself has not failed.
