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 Depicted as a flag with an X

What is MRA?

Minimum reception altitude Depicted as flag with R Altitude in order to identify an intersection/applies only to the reception of an off airway signal

What is MAA?

Maximum authorized altitude -limit VOR signal interference -keep you below military aircraft -keep you below high density approach corridors

What is OROCA?

Off route obstruction clearance altitude -used if you fly direct routings off designated airway -depicted in brown

What is TAF AMD and TAF COR?

Amended and corrected

What is NSW on TAF

No significant weather

How to read this winds aloft 34000 730649

Winds 230 @ 106kts -49C

What is 9900 on winds aloft?

Light and variable winds less than 5 kts

What makes GPS IFR certified?

-Designed for aircraft use -Permanently mounted in the aircraft -needs to be installed by qualified technician -database needs to be updated

What is RAIM?

Receiver Autonomous Integrity Monitoring - verifies the integrity or usability of the signals from the GPS satellites - needs 5 satellites or 4 satellites and a barometric altimeter to ensure the signals are reliable (fault detection)

What is RNP?

Requires navigation performance -statement of accuracy of the area navigation system -ex.RNP-0.3 means aircraft can remain 0.3 NM of its intended position 95% of the time

What is WAAS?

Wide are augmentation system -enhances the capabilities of GPS

When is no procedure turn required?

91.175 SHARPTT Straight in Hold in lieu Arc (DME) Radar vector (No) PT depicted Time approach Teardrop course reversal

Which substitution is permitted when an ILS component is inoperative?

A compass locator or precision radar may be substituted for the ILS outer or middle marker.

A VOR test facility does what?

Transmits a 360 degree radial in all directions.

When do you need to file an alternate airport?

3-2-1 rule If weather at destination isn’t at least 3SM, 2000’ AGL ceilings from 1hr before to 1hr after ETA, you need to file an alternate.
