When I received the bill of the ICC in 1981, the helicopter is a very rare instrument. In fact, at that time, few companies have been invited to work as a professional helicopter pilot. Today is very different. Instruments needed for most jobs, and all training programs include assessment. In addition, each pilot will start his coaching career (like most people) CFII.
Flight instruments at each airport for 30 years. Now with GPS approaches may be cheaper almost everywhere, so that IFR helicopter operations under more reasonable. However, there are restrictions on helicopters. The first interval.Helicopters typically takes about three hours of fuel. Have a great time, can be very difficult to get to your destination,brushless motor speed controller you will find a qualified alternative fuel must reserve in advance.
Due to the unique characteristics of the helicopter, CFR help limit the scope. Helicopters are to provide fuel for 30 minutes and not more than 45 minutes for airplanes (CFR 91 167 (3)) in relationship. E 'is used for a long time to determine if an alternate airfields required 91 CFR 167 (b) (2) provides a minimum below helicopters.
(I) helicopters for other aircraft. At least 1 hour before and one hour after the estimated time of arrival, the ceiling will be at least 2,000 feet above the airport elevation and the visibility will be at least 3 km from the statute.
(II) for helicopters. Estimated time of arrival and for 1 hour after the estimated time of arrival, the ceiling will be at least 1,000 feet above the airport elevation, or at least 400 feet above the highest minimum down approach, which is more visible state and at least 2 miles.
In 91 CFR 169 (c) (1) alternate airport IFR minimum time is also different.
(I), for aircraft other than helicopters: alternative minimum specified in the procedure, or if not specified the following standard approach minima:
(A) In case the process is the approach. 600 foot ceiling and 2 miles visibility status.
(B) For the procedure for non-precision approach. 800-foot ceiling and 2 miles visibility status.
(II) for helicopters flew ceiling 200 feet above the minimum approach, and the visibility is at least 1 km law, but not less than the minimum visibility for the approach of the flight.
IFR helicopter regulatory system helped save more.
