Block 1 Flashcards
What instruments operate off Rigidity?
- Attitude Indicator
- Heading Indicator
What instruments operate off Precession?
- Attitude Indicator (pendulous veins)
- Turn and Slip Indicator
- Turn Coordinator
Describe the gyroscopic principle of Rigidity in Space
When spinning at high speeds, gyros will resist tilting/turning in any direction other than around its spin axis
A/c will rotate around the spinning, upright gyro
What happens if the Static Port becomes blocked?
- Altimeter freezes
- VSI shows 0 (pressure equalizes through calibrated leak)
- Airspeed is inaccurate
How does the VSI work?
Measures the difference between initial pressure and new pressure
ANDS
Occurs when on E/W headings
UNOS
Occurs when on N/S headings and turning away
What is Variation?
The difference between True North and Magnetic North
What are the 4 ground based NAVAIDs
VOR
DME
ILS
NDB
What does the RMI show?
Magnetic Bearing
Tail shows VOR radial you’re on
What is the difference between Homing and Tracking?
Homing = No wind correction to the station Tracking = Maintaining consistent MB to the statio
What are some disadvantages/errors of the VOR? (there are 5)
- Expensive
- Line of Sight
- Service Volumes
- Cone of Confusion (needle freaks out when over the stations)
- Zone of Ambiguity (TO/FR flag disappears when abeam the station)
61.65 Requirements for an Instrument Rating requirements? (4)
PPL
English Proficient (cat 4+)
Ground training
Endorsements
61.65 Aeronautical Knowledge requirements? (3)
ATC Procedures
IFR nav and approaches
Safety and efficiency
61.65 Flight Proficiency requirements? (3)
50 hrs XC (10 in a/c)
40 hrs Instrument Time (15 from a CFII - 3 different kinds of approaches)
SImulators (10 hrs in a BATD, or 20 hrs in an AATD)
3 Segments of the GPS
- Space (Satellites)
- Control (Ground-Stations)
- User (Aircraft)
What requirements are there for flying IFR with GPS as the main NAVAID?
- Any Non-WAAS GPS must be equipped with RAIM
- WAAS GPS must meet standards
- MUST CHECK NOTAMs prior to IFR flight
- Must have an approved ALTERNATE means of navigation appropriate to flight
What are the 3 different CDI sensitivities with WAAS GPS navigation? When do they automatically activate?
- En-Route (30nm+ from destination) = 2nm full scale deflection either side
- Terminal (~30nm TO/FR) = 1nm full scale deflection either side
- Approach (Past Final Approach WP) = 0.3nm full scale deflection either side
