CH. 1 - Fundamentals Of IFR Flashcards
When is an instrument rating required for a pilot to operate as PIC of a civil aircraft?
When on an IFR flight plan, in weather conditions less than VFR minimums, or in Class A airspace.
What must an instrument rating be specific to in order to operate as PIC?
The category and class of aircraft flown.
What is required for a commercial pilot to carry passengers for hire at night or over 50 NM?
An instrument rating in the same category and class of aircraft.
What recent flight experience is required to act as PIC under IFR?
6 instrument approaches, holding procedures, and intercepting/tracking courses within the last 6 months.
What is required if an instrument pilot hasn’t met recent flight experience within 12 months?
They must pass an instrument proficiency check.
What conditions must be met for logging instrument time?
The pilot must be controlling the aircraft solely by reference to flight instruments in actual or simulated instrument conditions.
What must be logged when flying with a safety pilot in simulated instrument conditions?
The location and type of each instrument approach, and the name of the safety pilot.
What additional equipment is required for IFR flight beyond VFR day and night requirements?
Generator/alternator, radios, sensitive altimeter, inclinometer, clock, attitude indicator, rate of turn indicator, directional gyro.
How often must the static pressure system and altimeter be inspected under IFR?
Every 24 calendar months.
How often must VOR operational checks be made for IFR navigation?
Every 30 days.
What is the maximum allowable tolerance for a dual VOR check during an operational check?
±4° variation.
What is the maximum allowable tolerance for a ground-based VOT check during a VOR operational check?
±4° variation.
What is the maximum allowable tolerance for an airborne checkpoint during a VOR operational check?
±6° variation.
What details must be recorded after a VOR operational check?
The date, place, bearing error, and pilot signature.
Which flight instruments rely on the static system for air pressure?
The airspeed indicator, vertical speed indicator (VSI) and altimeter.
Which flight instrument relies on both the pitot and static systems?
The airspeed indicator.
What happens to the airspeed indicator when both the pitot tube and drain hole are blocked?
It acts as an altimeter.
How does the airspeed indicator behave when only the front of the pitot tube is blocked?
It reads zero.
How can calibrated airspeed (CAS) be determined?
By using ____________ airspeed, ___________ _____________, and outside _____________ ______________temperature with a flight computer.
**By using true airspeed, pressure altitude, and outside air temperature with a flight computer.
How does the altimeter determine altitude?
By measuring the difference between ____________ _____________ pressure and _____________ ______________ pressure.
By measuring the difference between sea level pressure and outside air pressure.
What is the approximate altitude change for a 1-inch change in altimeter setting?
Roughly 1,000 feet.
What should the altimeter be set to above FL180?
Standard pressure of 29.92”Hg.
What does the turn coordinator indicate?
The rate of roll and rate of turn.
How is bank angle indirectly indicated on the turn coordinator?
By the movement of the _____________ _____________, which shows a turn based on the _____________ of _____________.
By the movement of the miniature airplane, which shows a turn based on the rate of turn.
