Instrument Flashcards
Pirep
Pilot weather report
Metar
Routine surface weather report. Every hour.
SPECI ISSUED WHEN SIGNIFICANT CHANGE IN ONE or more reported elements since last metar
TAF
Terminal aero dome forecast
5SM around station
Issued 4 times a day, every 6 hours
Class B airspace dimensions
Surface to 10,000 MSL
Inner ring 10NM
Outer ring 30NM
Class D airspace dimensions
4NM radius 2500 AGL
Hold for release
May not takeoff until being released for IFR departure
VOR check sign off
(hint: DEPS)
Date
Error
Place
Signature
Magnetic compass errors and limitations (hint: DVMONA)
Deviation
Variation
Magnetic dip
Oscillation
North/south turn errors (UNOS- undershoot north/overshoot south)
Acceleration errors (ANDS - accelerate north/decelerate south)
Oxygen requirements
Part 91 only: part 121 and 135 are different
12,500-14,000 crew must use O2 for flight over 30 min
+14,000 crew must be provided and use O2 for total duration of flight
+15,000 each occupant must be provided with O2
Instrument Ice
Structural ice forming over aircraft
Instruments and sensors: pitot + static
Minimum equipment required for VFR day flight (hint: ATOMATOFLAMES)
Altimeter Tachometer Oil temp indicator- each engine Manifold pressure gauge- each engine Airspeed indicator Temperature gauge - for each liquid Oil pressure gauge- each engine Fuel quantity gauge - each tank Landing gear position lights (retractable) Anti collision lights Magnetic compass ELT (if required by 91.207) Safety belts/shoulder harnesses
Airspace speed limits
Less than 10,000 250kts
Below class B 200kts
Class C/D within 4NM and below 250-200kts
Above 10,000 Mach 1
Static port blockage
Airspeed indicator- shows correct speed if you at altitude blockage occurred
Lower altitude - higher than it should
Higher altitude - lower than it should
Altimeter - will freeze on altitude where it was blocked
VSI - freezes on zero
Gyroscopic instruments
Attitude indicator- rigidity in space
Heading indicator- rigidity in space
Turn indicators - principle of precession
DP(departure procedure)
- must be assigned by ATP
- must at least possess textual description
- provides obstruction clearance from terminal area to the enroute structure
- detailed procedure to depart airport
- transition to enroute structure safely
Approach clearance minimums
Contact +visual
Contact:
- must be requested by the pilot
- at least 1sm reported ground visibility and remain clear of clouds
- available at airports with approved instrument approach procedures
Visual:
- initiated by pilot or ATC
- Requires at least 1000’ ceilings + 3sm visibility
- pilot must have airport or traffic to follow in sight at all times
4 parts of an ILS
Localizer
Glide slope
Marker beacons
Approach light system
Mandatory reports under IFR
Hint: MARVELOUSVFR500
Missed approach Airspeed +\- 10kts Reaching holding fix(time+alt) VFR on top ETA change +\- 3 min Leaving holding fix/point Outer marker Unforecasted weather Safety of flight Vacating an altitude/FL Final approach fix Radio/Nav failure Compulsory reporting points 500 unable climb/descent 500 fpm
*required only in non radar environment
What are your personal minimums
1000ft ceiling + 3sm visibility
Lower mins over time with experience
Preflight self assessment
Hint: IMSAFE
Illness Medication Stress Alcohol Fatigue Emotion
To carry passengers as PIC
- 3 takeoffs and landings in last 90 days in same category, class, and type
- periods between 1 hour after sunset to 1 hour before sunrise: 3 takeoffs and landings to a full stop in last 90 days during that period
- to act as PIC; flight review in last 24 calendar months
Holding pattern timing
Adjust outbound leg so inbound leg takes:
- at or below 14,000 MSL 1 min
- above 14,000 MSL 1.5 min
- DME/GPS holds -fly outbound leg to the specified distance from the fix/waypoint
Aircraft documents required for flight
Hint: ARROW
Airworthiness certificate Registration certificate Radio station license (for international flights) Operating limitations + AFM Weight + Balance data
Class B airspace, basic VFR weather minimums
3SM visibility +stay clear of clouds
