Hi friends: As I have already posted the T.O. from Havanna with the fully ladden Tu-114 even bevore sunrise was "marginal" and at the border of the airplanes physical abilities. So clearing the hills around MUHA was a delicate affair. Here leaving MUHA from RWY 05 shortly before sunrise.  More than a 400 ft/min climb was not possible, so the gear had to stay out.  After clearing the hill, finally the gear could be stored.  People who lived that personally swear the roar of the NK-4 engines and the whine of the 8 propellers did wake up nearly everbody in Havanna. Kind regards Walter |

Sweet flying there Walter. I'm pleased that you displayed the essence of historic jet/turboprop flying and that is to wake up and upset as many neighbors to the airport as possible  Cheers, Nathan |

Hello Walter Just curious as for the reason of waiting so long to raise the gear   Herman |

That was a decision of the Tu-testpilot. As the T.O. was marginal he wanted to avoid disturbances of the airflow by the opening geardoors and the retracting gears. So he put aside the sowjet standard procedure to raise the gear between 6 and 12 m AGL. But gossip goes that in the case of an engine problem after V1 the 114 would not have made it. The hill in the picture is not very high (around 100 m) but sealed the fate of an IL-62M for flight Cubana 9646 on 3 rd of september 1989. The accident was attributed to a microburst and an inadaquate take off decision and procedure.
Kind regards
Walter

Hi:
If somebody wants to "fly" that T.O. with "my" Tu-114 at 25 C deg ambient temprature: Dont use pitot heat, as the panels internal logic together with the FS9 logic takes that as "carburator heat" of a C-172 and decreases the engine power considerably.
Kind regards
Walter
