Advanced IFR 2 Flashcards
How do you read the cdi needle?
Full displacement is 10 degrees (from center to either side) each dot is 2 degree increments.
Winds at 5,000 feet AGL on a particular flight are southwesterly while most of the surface winds are southerly. This difference in direction is primarily due to
friction between the wind and the surface.
In the northern hemisphere, Coriolis force deflects the pressure gradient force wind to the right until the wind blows approximately parallel to the isobars. Surface friction reduces this deflection so that a southwesterly wind becomes southerly.
Frontal waves normally form on
slow moving cold fronts or stationary fronts.
Frontal waves and cyclones (areas of low pressure) usually form on slow-moving cold fronts or on stationary fronts.
Under which conditions is hydroplaning most likely to occur when landing?
During conditions of standing water, slush, high speed, and smooth runway texture.
In addition to a VOR receiver and two-way communications capability, which additional equipment is required for IFR operation in Class B airspace?
An operable coded transponder having Mode C capability.
FAR 91.131
During IFR en route operations using an approved TSO-C129 or TSO-C196 GPS system for navigation, what must the aircraft have additionally?
the aircraft must have an approved and operational alternate navigation system appropriate for the route.
Aircraft using un-augmented GPS (TSO-C129 or TSO-C196) for navigation under IFR must be equipped with an alternate approved and operational means of navigation suitable for navigating the proposed route of flight.
A generally recommended practice for autopilot usage during cruise flight in icing conditions is
periodically disengaging the autopilot and hand flying the airplane.
Pilots may consider periodically disengaging the autopilot and hand flying the airplane when operating in icing conditions. When the autopilot is engaged, it can mask changes in handling characteristics due to aerodynamic effects of icing that would be detected by the pilot if the airplane were being hand flown.
What should be the indication on the magnetic compass as you roll into a standard-rate turn to the left from a west heading in the Northern Hemisphere?
The compass will indicate the approximate correct magnetic heading if the roll into the turn is smooth.
An initial turn from either east or west will show a correct indication if the turn is done smoothly.
What frequency is normally available at all FSS?
122.2
What point at the destination should be used to compute estimated time en route on an IFR flight plan?
The point of first intended landing.
Reception of signals from an off airway radio facility may be inadequate to identify the fix at the designated MEA. In this case, which altitude is designated for the fix?
MRA.
The minimum reception altitude, is the lowest altitude at which an intersection can be determined.
What are the vertical limits of a transition area that is designated in conjunction with an airport having a prescribed IAP?
700 feet AGL or more to the base of the overlying controlled airspace.
There are Class E airspace areas beginning at either 700 or 1,200’ AGL used to transition to/from the terminal or en route environment. These extend upward to the overlying or adjacent controlled airspace. 700’ is the more common base.
FAR 71.71
A ‘CRUISE FOUR THOUSAND FEET’ clearance would mean that the pilot is authorized to
vacate 4,000 feet without notifying ATC.
The term “cruise” may be used instead of “maintain” to assign a block of airspace to a pilot. Climb / descent within the block is to be made at the discretion of the pilot.
On the taxi check, the magnetic compass should
swing freely and indicate known headings.
A common type of ground or surface based temperature inversion is that which is produced by
ground radiation on clear, cool nights when the wind is light.
An inversion is an increase in temperature with altitude - the lapse rate is inverted. It often develops near the ground on clear, cool nights when the wind is light.
How can you know what the MOCA is on an IFR chart?
It has an asterik.
During recoveries from unusual attitudes, level flight is attained the instant
the altimeter and airspeed needles stop prior to reversing their direction of movement.
When making an instrument approach at the selected alternate airport, what landing minimums apply?
The landing minimums published for the type of procedure selected.
Are military training routes above 1500 feet depicted on high or low altitude ifr charts?
High
What is indicated by the term ‘embedded thunderstorms’?
Thunderstorms are obscured by massive cloud layers and cannot be seen.
When moist, unstable, warm air overrides a shallow front, there can be hidden thunderstorms among the usual clouds – embedded thunderstorms. They are more common with warm or stationary fronts.
