135 IFR take-off minimums for a twin engine aircraft

Asked by: 2613 views , , , ,
FAA Regulations

Following is my understanding of Part 135 IFR take-off minimums for a twin engine aircraft:

1 SM visibility or an RVR of 5,000 ft, unless the pilot was assigned and accepted a SID (in this case the minimums of the SID apply) or the runway has non standard take-off minimums

To take off IFR from an airport where the current weather is below the landing minimums, but meets the takeoff minimums, the pilot must declare a takeoff alternate within 1 hour of normal flying time, with weather suitable for landing at the scheduled arrival time.

I would appreciate comments, corrections, additions.

Thanks

    Correct statement. Just keep in mind some of the definitions used.
    For example, the takeoff alternate must be within 1 hour, at NORMAL CRUISE SPEED. That definition could be different between companies.
    Refer to your company GOM (general operations manual) for exact definitions and regulations.

    Also, 99% of the time, your company will allow for a lower takeoff than 1SM. those requirements will also be in the GOM for the company. Example, you can takeoff 600RVR as long as you have HIRL and centerline lights.
