Aviation Flight Instrument Rating Flashcards

Which types of airspace are depicted on the En Route Low Altitude Chart?

Answer: Limits of f controlled airspace, military routes and special use airspace

En Route Low Altitude Charts (IFR) are designed for instrument flight rules operations below 18,000 feet MSL. They depict essential information for IFR navigation, including the boundaries of controlled airspace, military training routes (MTRs), and various types of Special Use Airspace (SUA). This information is crucial for IFR flight planning and execution in the low altitude structure.

What indications are displayed by the miniature aircraft of a turn coordinator?

Answer: Rate of roll and rate of turn

The miniature aircraft on a turn coordinator indicates the rate of roll and the rate of turn. When the aircraft is rolling, it shows the rate at which the aircraft is entering or exiting a turn. Once established in a turn, it indicates the rate at which the aircraft is changing its heading, providing crucial information for coordinated turns.

When turning onto a taxiway from another taxiway, the "Taxiway directional sign" indicates

Answer: designation and direction of taxiway leading out of an intersection

A taxiway directional sign is yellow with a black inscription and an arrow. It indicates the designation and direction of a taxiway leading out of an intersection. These signs are essential for pilots to navigate complex airport layouts, clearly showing which taxiways are available and in which direction they lead, preventing wrong turns.

ATC can issue a STAR

Answer: When ATC deems it appropriate, unless the pilot requests "NO STAR"

A Standard Terminal Arrival Route (STAR) is a pre-planned instrument flight rule (IFR) arrival procedure designed to streamline traffic flow into busy airports. ATC can issue a STAR when they deem it appropriate for efficiency and safety. However, pilots have the option to decline a STAR by requesting 'NO STAR' in their flight plan or upon initial contact, if they prefer a different arrival procedure.

If both the ram air input and drain hole of the pitot system are blocked, what airspeed indication can be expected?

Answer: Increase of indicated airspeed during a climb

If both the ram air input and the drain hole of the pitot tube are blocked, air is trapped in the pitot line. As the aircraft climbs, static pressure decreases, but the trapped pitot pressure remains constant. This constant pitot pressure, combined with decreasing static pressure, causes the airspeed indicator to show an increase in indicated airspeed, even if the true airspeed is constant or decreasing.

What is the ARTCC discrete frequency at the COP on V208 southwest bound from HVE to PGA VOR/DME?

Answer: 127.55

To determine the ARTCC discrete frequency at a specific Changeover Point (COP) on an airway, one must consult an En Route Low Altitude Chart. These charts provide detailed information, including frequencies, for various segments of airways. For V208 southwest bound from HVE to PGA VOR/DME, the chart indicates 127.55 MHz as the correct ARTCC discrete frequency.

What is the correct sequence in which to use the three skills used in instrument flying?

Answer: Cross check, instrument interpretation, and aircraft control

The fundamental skills for instrument flying are cross-checking, instrument interpretation, and aircraft control, performed in that specific sequence. Pilots first cross-check multiple instruments to gather a comprehensive picture of the aircraft's attitude and performance. Then, they interpret the information to understand what the aircraft is doing, and finally, they apply the necessary aircraft control inputs to achieve the desired flight path.

Which condition would cause the altimeter to indicate a lower altitude than actually flown (true altitude)?

Answer: Air temperature warmer than standard

Altimeters are calibrated to a standard atmosphere. If the actual air temperature is warmer than standard, the air is less dense. In less dense air, the altimeter will indicate a lower altitude than the aircraft's true altitude, as the pressure levels are 'stretched out' higher than the instrument assumes. This is a critical concept for terrain clearance, often summarized as 'hot to cold, look out below'.

What are some characteristics of unstable air?

Answer: Turbulence and good surface visibility

Unstable air is characterized by significant vertical air movement, which leads to turbulence. This vertical motion also tends to mix the air, dispersing pollutants and moisture, resulting in good surface visibility. Cumuliform clouds, such as cumulus and cumulonimbus, are typically associated with unstable air conditions.

How can an IAF identified on a Standard Instrument Approach Procedure (SIAP) Chart?

Answer: All fixes that are labeled IAF

An Initial Approach Fix (IAF) is a fix from which an instrument approach procedure begins. On a Standard Instrument Approach Procedure (SIAP) chart, IAFs are explicitly identified by the letters 'IAF' next to the fix name or symbol. These fixes serve as designated starting points for the approach, allowing pilots to transition from the en route structure to the approach segment.

In the case of operations over an area designated as a mountainous area where no other minimum altitude is prescribed, no person may operate an aircraft under IFR below an altitude of

Answer: 2000 feet above the highest obstacle

For IFR operations in mountainous areas where no other minimum altitude is prescribed, FAA regulations (14 CFR Part 91.177) require a minimum altitude of 2,000 feet above the highest obstacle. This altitude must be maintained within a horizontal distance of 4 nautical miles from the course to be flown. This regulation ensures adequate terrain clearance for instrument flights in challenging terrain.

You intend to carry passengers for hire on a night VFR flight in a single engine airplane within a 25 mile radius of the departure airport. You are required to possess at least which rating(s)?

Answer: A Commercial Pilot Certificate with a single engine and instrument (airplane) rating

To carry passengers for hire, a pilot must hold at least a Commercial Pilot Certificate. Additionally, to carry passengers for hire at night, FAA regulations (14 CFR Part 61.129(a)(4)) require the pilot to hold an instrument rating in the appropriate aircraft category and class. This ensures the pilot has the necessary skills and qualifications for commercial night operations, which inherently carry higher risks.

Which instrument provides the most pertinent information for pitch control in straight and level flight?

Answer: Altimeter

In straight and level flight, the primary goal for pitch control is to maintain a constant altitude. Therefore, the altimeter provides the most pertinent information, directly indicating whether the aircraft is climbing, descending, or maintaining level flight. While the attitude indicator shows the aircraft's pitch attitude, the altimeter reflects the actual outcome of that attitude on altitude.

What reports are required of a flight operating on an IFR clearance specifying VFR on Top in a non radar environment

Answer: The same reports that are required for any IFR flight

A 'VFR on Top' clearance allows an IFR flight to operate in VFR conditions above an overcast layer, maintaining VFR cloud clearance and visibility requirements. However, the flight remains an IFR flight for separation purposes. Therefore, all standard IFR position reports and other required reports, such as vacating an altitude or reaching a holding fix, are still mandatory, especially in a non-radar environment where ATC relies solely on these reports for tracking.

Which statement is correct regarding the use of cockpit lighting for night flight?

Answer: The use of regular white light, such as a flashlight, will impair night adaptation

The human eye takes time to adapt to darkness (night adaptation). Exposure to bright white light, even for a short period, can significantly impair this adaptation, making it harder to see outside the cockpit at night. Pilots should use dim, red lighting in the cockpit to preserve night vision, as red light has minimal impact on the rods in the eyes responsible for low-light vision.

At STRUT intersection headed eastbound, ATC instructs you to hold west on the 10 DME fix west of LCH on V306, standard turns, what entry procedure is recommended?

Answer: Direct

To determine the correct holding entry, one must visualize the holding pattern relative to the aircraft's current position and direction of flight. If the aircraft is headed eastbound on V306 and instructed to hold west on the 10 DME fix west of LCH, the holding course is 270 degrees (west). Since the aircraft is approaching the holding fix from a direction within the direct entry sector, a direct entry is recommended.

For planning purposes, what is the highest useable altitude for an IFR flight on V573 from the HOT VORTAC to the TXK VORTAC?

Answer: 16000 feet MSL

To determine the highest usable altitude for an IFR flight on a specific Victor airway, one must consult an En Route Low Altitude Chart. These charts display the Maximum Authorized Altitude (MAA) for each segment of an airway. For V573 between HOT and TXK, the chart indicates an MAA of 16,000 feet MSL, which is the highest altitude ATC can clear an aircraft to operate on that airway segment.

Which practical test should be made on the electric gyro instruments prior to starting an engine?

Answer: Turn on the electrical power and listen for any unusual or irregular mechanical noise

Before engine start, when electrical power is applied, pilots should listen carefully to the electric gyro instruments, such as the attitude indicator and heading indicator. Any unusual or irregular mechanical noise, like grinding or whining, could indicate a malfunction in the gyro's bearings or motor. This crucial pre-flight check helps ensure instrument integrity before flight.

What is the difference between a Localizer Type Directional Aid ( LDA ) and the ILS localizer?

Answer: The LDA is not aligned with the runway

The primary difference between a Localizer Type Directional Aid (LDA) and an ILS localizer is that an LDA is not necessarily aligned with the runway centerline. While an ILS localizer provides a course aligned with the runway, an LDA provides a localizer-type course that may be offset by up to 30 degrees from the runway heading. LDAs can also provide a glide slope, similar to an ILS, but their defining characteristic is the potential for offset alignment.
