  • Page 31: Emergency Landing

    ALPHA Electro Emergency procedures REV.0 WARNING! The decision where to land when landing out is final! Changing your mind, even if you happen to come across a different, perhaps more appropriate landing site, should be your last resort. Motor restart in flight NOTE: The minimum height, at which a motor restart attempt can be made safely, is 1000 ft AAL.

  • Page 32: Smoke In Cockpit

    ALPHA Electro Emergency procedures REV. 0 Battery system fire Indication of battery fire is dense smoke and a distinctive chemical smell. Disengage both battery circuit breakers, land immediately and leave the aircraft as soon as possible. WARNING! Be aware that lithium battery fires are extremely dangerous because they are self-sustaining! They are a result of chemical reactions and are impossible to extinguish.

  • Page 33: Battery Failure

    ALPHA Electro Emergency procedures REV.0 BPRS Please refer to Appendix (9-2) for information about the use of Ballistic Parachute Rescue System during emergency. Battery failure With two battery packs on board the battery system is automatically redundant. A failure of one battery pack will be displayed on EPSI570 as a warning and the system will automatically switch to a single-battery mode, enabling continuation of flight.
  • Page 34 ALPHA Electro Emergency procedures REV. 0 Motor, power controller and battery temperatures are influenced mostly by two factors: ambient temperature and power setting. The pilot has direct control of the power setting and thus affects the powertrain component temperatures. Avoid high power setting for long periods, especially in a hot environments (80-85 °F/26-30 °C and higher).

It is highly recommended to have the aircraft verified for airworthiness by authorised service personnel.

  • Page 73: Tie Down

    Ideally, the aircraft should be stored in a hangar. For increased in-hangar maneuvrability use of an original Pipistrel push-cart is recommended. Stuff the battery bay cooling inlets with some foam or a rag to prevent the ingress of dirt, dust, small animals, etc..

  • Page 74: Keeping Your Aircraft In Perfect Shape

    Keeping your aircraft in perfect shape In order for the ALPHA Electro to perform the way it should, all of the airframe’s surfaces must cleaned on a regular basis. This is especially true for the wing’s leading edges, which can seriously affect per- formance if left dirty.

  • Page 75: Rev.0

    Cleaning the transparent Lexan surfaces All the of the ALPHA Electro’s window surfaces are made of Lexan. Cleaning Lexan is not the same as cleaning Plexiglas. It is really important to only use clean water (no cleaning solutions are necessary) when cleaning and a really clean drying towel.
