FARs Flashcards
91.167 fuel requirements for IFR
IFR flight helicopter to destination and then alternate and then after for 30 minutes minimum
91.169 IFR planning minimums
At time of arrival and for 1 hour after the ceiling WILL be 400 feet or higher than lowest approach minima
OR 1000 feet above field elevation
And at least 2 SM visibility
Alternate
200 foot ceiling greater than applicable approach to be flown
And 1 mile Vis
But never less visibility than the approach.
Conventional approach (NON copter) visibility heights and speeds
Visibility: 1/2 CAT A minima or 1200 RVR but never less than 1/4 mile. Unless annotated as VISIBILITY REDUCTION BY HELICOPTER NA
MDA /DA: as published for CAT A minima
Speed: enroute to final approach segment speeds up to any of the published Categories
Final appr segment must be slowed to 90 or less before MAP to apply the reduced (1/2 Vis) reduction for helicopters
GPS Copter procedure approach
Visibility and MDA/DA : as published
Speed: 90 kts on published track except 70 kts on final up to 7.5 degrees approaches and the. 55 kts 7.5-9 degrees angle
Instrument currency requirements
May not act as PIC in IFR if in preceding 6 calendar months he or she has not:
Performed and logged under actual or simulated conditions either in a simulator or appropriate category aircraft
6 instrument approaches
Holding procedure
Intercept and track courses with Nav systems
If expired an IPC must be done.
91.121 altimeter setting
Must have altimeter setting when below 18,000 feet from a station within 100 miles along your route
91.157
Special VFR weather minimums
Allows helicopters to operate SVFR even below 1mile visibility like fixed wing.
Allows helicopter operate at night SVFR while other aircraft cannot
Part 91 IFR flight with inop equipment
A pilot may defer certain items without an MEL if those items are not required by the type certificate, CFRs, or any ADss AND the flight can be performed safely without them.
If item is disabled or removed a logbook entry MUST be made
Helicopter VFR minimums (same as fixed wing with 2 exceptions)
Class A N/A Class C, D, E 500 below 1000 above 2000 horizontal 3 SM Vis (Except class E above 10K 1000,1000,1mile horizontally and 5 SM Vis) Class B clear of clouds 3 SM Vis
Class G. Day or night. Clear of clouds
SVFR for BCDE surface area
Clear of clouds day or night that’s it. No Vis limit
Required reports to ATC
Time and altitude entering holding or reaching a fix cleared to
When leaving assigned holding fix or point
Change in filed airspeed 5 percent or 10 knots(at cruising speed)
When vacating previously assigned altitude
When unable to climb/descend at least 500 fpm
When executing the missed
Minimum safe altitudes
91.119
Helicopters may be operated at less than prescribed( congested areas 1000 feet above highest obstacles and 2000 feet horizontal………or 500 feet above obstacles in “other than congested” areas
Helicopters “if operations is conducted without hazard to persons or property on the surface “
Typical dimensions of airspace
Class A above 18K
Class B upwards to 10,000 feet can extend many miles laterally
Class C usually 4000 above airport 5 and 10nm radius
Class D usually 2500 above airport and average 4.3 nm radius
Class G 700 or 1200 if not depicted its 1200
Class E 1200 to 18000 (there are exceptions)
Class E VFR minimums
VFR weather minimums above 10 thousand feet 1000 above 1000 below 1 mile horizontal And 5 miles Vis. Below 10,000 500 below 1000 above 2000 horizontal And 3 mile vis
