IFR 137 Oral Exam Questions
Are the courses depicted on an En-route Low Alt Chart mag or true
course? - ✔ ✔ Mag Course
Are the winds of a "FB" true or magnetic? - ✔ ✔ True north
For IFR flight, what is the max allowable error for an altimeter? - ✔
✔ More then 75 feet from field elevation
How do you determine if takeoff mins are not standard for an
airport? - ✔ ✔ If an airport has non-standard takeoff minimums, a
"triangle T" symbol will be placed in the notes section of the
instrument procedure chart.
How does an altimeter work? - ✔ ✔ Aneroid wafers expand and
contrast as the atmospheric pressure changed, and through a shaft
and gear linkage, rotate pointers on the dial of the instrument.
How does the airspeed indicator operate? - ✔ ✔ It measures the
difference between ram pressure from the pitot head and
atmospheric pressure from the static source.
How does the magnetic compass work? - ✔ ✔ Magnets on the
compass card align themselves parallel to the earths lines of
magnetic force.
How does the VSI work? - ✔ ✔ Changing pressure expands or
contracts a diaphragm connected to the indicating needle through
gears and levers. The VSI is connected to the static pressure line
through a calibrated leak; it measures differential pressure.
How is a fly-by waypoint dictated? - ✔ ✔ Four-pointed star
How is a fly-over waypoint dictated? - ✔ ✔ Four-pointed star
enclosed in a circle
,If no MAP is depicted, how is the MAP determined - ✔ ✔ the MAP is
the airport
Logbook Reqs for Recency of Experience - ✔ ✔ 1. Location and
type of each IAP
2. Name of the safety pilot, if required.
Recency of Experience Requirements - ✔ ✔ 66HIT
1. Within the preceding 6 CAL MONTHS, logged at least 6
INSTRUMENT PROCEDURES, HOLDING Procedures,
INTERCEPTING AND TRACKING.
-Biannual Flight Review
- Preceding 90 days completed 3 landings & T/O
- Preceding 90 days completed 3 Full stop landing & T/O
- 6 month grace period with safety pilot
- After grace period, must complete Proficiency check
Required Qualifications for to be a Safety Pilot - ✔ ✔ 1. Possess a
curent médical
2. Posses a PPL in the same Category and Class
3. If under IFR, must also be IFR rated
What actions must be taken when approaching a holding fix at an
airspeed in excess of max holding speed? - ✔ ✔ Start speed
reduction when 3 min or less from the fix.
What are NOTAMs? - ✔ ✔ Time critical aero info
, What are PIREPS? - ✔ ✔ A PIREP is a Pilot weather report, and
reports meteorological phenomena encountered by aircraft in flight.
There are two types of PIREPS routine (UA) and urgent (UUA)
What are radar summary charts? - ✔ ✔ Computer generated chart
that displays information about type, intensity, configuration,
coverage, echo top, and cell movement of precip. Severe wealth is
plotted if necessary. They are available HOURLY with a valid time 35
min past the hour.
What are terminal aerodrome forecasts (TAFs) - ✔ ✔ Report of
meteorological conditions within a 5 SM radius from the center of the
airports runway complex during a 24-hr period.
What are the alternate airport requirements? - ✔ ✔ 1-2-3 Rule
1 hr +/- ETA, 2,000 ft clgs, 3 mile vis
What are the approach speeds for different aircraft approach
categories? - ✔ ✔ Cat A; -91
Cat B: 91-121
Cat C: 121-141
Cat D: 121-166
Cat E: 166+
What are the compass errors? - ✔ ✔ VDMONA
1. Variation- difference between true and magnetic north.
2. Deviation- electrical and magnetically disturbances in the A/C.
3. Magnetic Dip- magnet wants to go towards the earth center at
high latitudes.
4. Oscillation- erratic movement of the compass card due to
turbulence and rough control
