IR Flashcards
What are the recency requirements for IFR flight?
Intercepted and track courses thru the use of navigation system, performed holding procedures, and flown at least 6 instrument approaches within preceding 6 months
What is kinesthetic sense?
Describe an awareness of position obtained from nerves in your skin, joints, and muscles
What is spatial disorientation?
Conflict between signals relayed by your central vision and info provided by your peripheral vision
Supplemental oxygen at night
FAA advises oxygen use at 5,000MSL when flying at night
What altimeter setting do you use at 18,000 MSL and above?
29.92
How do you calculate approx bank for a standard rate turn?
Angle of bank = [True Airspeed in knots / 10] + 5
What are the primary instruments for straight and level flight?
Pitch - altimeter
Power - airspeed indicator
Bank- heading indicator
Turning errors, magnetic compass?
UNOS
Undershoot North, Overshoot South
Southerly Heading - compass leads, roll out late
Northerly Heading - compass lags, roll out early
There are no compass turning errors during turns from easterly or westerly headings
Accelerate/Decelerate Errors, magnetic compass
-Greatest when going East/West
-ANDS
When you accelerate, points north
When you decelerate, points south
What is magnetic variation?
Difference between true and magnetic north
What is magnetic deviation?
Compass may be affected by metals and electrical fields in the airplane
Errors in both pitch and bank indication on an attitude indicator are usually at a maximum as an aircraft rolls out of a?
180 turn
What is MEA?
Minimum enroute altitude
Generally guarantees obstruction clearance and navigation signal coverage
What is MAA?
Maximum authorized altitude
Keeps you from receiving more than one VOR station at a time
What is MOCA?
Minimum obstacle clearance altitude
Meets obstacle clearance requirements for entire route and acceptable navigational signal within 25 SM, 22 NM of a VOR
Distress vs Urgency
Distress - serious imminent danger and require immediate assistance ex. Fire, mechanical failure, structural damage
Urgency - not immediately dangerous but requires prompt assistance ex. Low fuel, poor weather
Body sense orientation by which three systems?
Visual system
Motion sensing (vestibular)
Position sensing (postural)
What are pitch controls for level flight?
Primary altimeter
Secondary Airspeed indicator, VSI and Attitude indicator
What are the primary and secondary instruments for bank control during level flight?
Primary heading indicator
Secondary turn coordinator, attitude
Instruments required for IFR flights?
GRABCARD
Generator or alternator
Radio
Attitude indicator
Ball (inclinometer)
Clock
Altimeter
Rate of turn (turn coordinator)
Directional Gyro
Mandatory IFR Reports
MARVELOUS VFR C 500

Airspeed change more than 10kts or 5%
Reaching a holding fix
VFR on top altitude change
ETA change more than 3 minutes
Leaving a holding fix
Outer market inbound
Unforecast weather
Safety of flight issues
Vacating an altitude

Three fundamental skills in attitude instrument flying
Cross check
Instrument interpretation
Aircraft control
What are fuel requirements for IFR flight?
Enough fuel to fly to the first airport, the alternate airport and 45 min at normal cruising speed
When do you need to carry enough fuel to fly to an alternate airport?
1-2-3 rule
1hr before, 2,000 ft ceilings, 3SM visibility
What is MCA?
Minimum crossing altitude
Start climb before fix because of higher terrain
