REGP91 Flashcards
Speed limit below 10,000 feet MSL, in general
250 knots unless otherwise authorized
§91.117 Aircraft speed.
Speed limit at or below 2,500 feet AGL within 4 nautical miles of the primary airport of a Class C or D airspace area
200 knots unless otherwise authorized
§91.117 Aircraft speed.
Speed limit in the airspace underlying a Class B airspace area designated for an airport or in a VFR corridor designated through such Class B airspace area
200 knots unless otherwise authorized
§91.117 Aircraft speed.
Standard alternate weather minimums with respect to selecting an airport as an alternate
Unless otherwise authorized, no person may specify an alternate airport in an IFR flight plan unless appropriate weather reports or weather forecasts, or a combination, indicate that, at the estimated time of arrival at the alternate airport, the ceiling and visibility will be at or above the following weather minima:
Precision approach procedure.
Ceiling 600 feet and visibility 2 statute miles.
Non-precision approach procedure.
Ceiling 800 feet and visibility 2 statute miles.
§91.169 IFR flight plan: Information required.
The applicable authorized DA/DH or MDA/MDH is the highest of what three factors?
(1) The DA/DH or MDA/MDH prescribed by the approach procedure.
(2) The DA/DH or MDA/MDH prescribed for the pilot in command.
(3) The DA/DH or MDA/MDH appropriate for the aircraft equipment available and used during the approach.
§91.175 Takeoff and landing under IFR.
Standard takeoff minimums if not prescribed for a particular airport
Aircraft having two engines or less
1 statute mile visibility.
Aircraft having more than two engines
1/2 statute mile visibility.
§91.175 Takeoff and landing under IFR.
The minimum IFR altitude when not published.
Mountainous area and non-mountainous area.
Designated mountainous area
2,000 feet above the highest obstacle within a horizontal distance of 4 nautical miles from the course flown.
Otherwise, 1,000 feet above the highest obstacle within a horizontal distance of 4 nautical miles from the course flown.
§91.177 Minimum altitudes for IFR operations.
Can an aircraft be operated below the MEA (Minimum Enroute Altitude)?
Yes. If both a MEA and a MOCA are prescribed for a particular route or route segment, a person may operate an aircraft below the MEA down to, but not below, the MOCA, provided the applicable navigation signals are available. For aircraft using VOR for navigation, this applies only when the aircraft is within 22 nautical miles of that VOR.
§91.177 Minimum altitudes for IFR operations.
IFR cruising altitudes based on direction of flight
Magnetic course 0° through 179°, any odd thousand foot MSL altitude (or Flight Level at and above 18,000 feet MSL); or
Magnetic course 180° through 359°, any even thousand foot MSL altitude (or Flight Level at and above 18,000 feet MSL)
§91.179 IFR cruising altitude or flight level.
What route and altitude applies in the event of a two-way communication failure while in IFR conditions?
(1) Route.
(i) Route assigned in the last ATC clearance received;
(ii) If being radar vectored, the direct route from the point of radio failure to the fix, route, or airway specified in the vector clearance;
(iii) In the absence of an assigned route, the route ATC has advised may be expected in a further clearance; or
(iv) In the absence of an assigned route or a route that ATC has advised may be expected in a further clearance, the route filed in the flight plan.
(2) Altitude. The highest of the following altitudes for the route segment being flown
(i) The altitude assigned in the last ATC clearance received;
(ii) The minimum altitude prescribed for IFR operations; or
(iii) The altitude ATC has advised may be expected in a further clearance.
§91.185 IFR operations: Two-way radio communications failure.
