Block 4 Flashcards
What does a pilot need to do a STAR?
To use an instrument departure procedure, the pilot must possess either the textual or the graphic form of the approved procedure
What is OBS
Omni bearing selector
What is TC?
True course, This is the course measured from your navigation plotter when you plot your flight on your map.
What is Magnetic course?
is the airplane’s course across the ground, relative to magnetic north.
When do we need an alternate
1 hr before/after ETA
2000 ceiling
3sm viz
What is MEA?
minimum enroute altitude
Obstacle Clearance 1,000’ in Non-Mountainous Areas 4 NM either side of course centerline 2,000’ in Mountainous Areas 4 NM either side of course centerline
Suitable Navigation Coverage
Throughout the entire route segment
what is a MOCA
minimum obstruction clearance altitude
Obstacle Clearance 1,000’ in Non-Mountainous Areas 4 NM either side of course centerline 2,000’ in Mountainous Areas 4 NM either side of course centerline
Suitable Navigation Coverage
For 22 NM from each VOR
what is an OROCA
off route obstruction clearance altitude
It will provide terrain clearance:
Non-Mountainous Areas: 1,000’
Mountainous Areas: 2,000’
Airports with an approved Precision Approach Procedure:
600’ Ceiling and 2SM Visibility at ETA
Airports without an approved Precision Approach BUT with an approved Non-Precision Approach Procedure:
800’ Ceiling and 2SM visibility at ETA
Airports with no approved IAP (Instrument Approach Procedure):
Ceiling and Visibility to allow a descent from the MEA Down to the Alternate Airport (and landing) Under VFR Conditions at the ETA
How can we get our IFR clearance?
Call Flight Service (Radio)
Call Center/Approach Directly
Use a clearance delivery phone number (chart supplement)
what altitude do we fly in lost comms scenario?

When the Clearance Limit is a point from which an approach begins:
If an EFC (Expect Further Clearance Time) has been received…
Commence descent and approach as close as possible to the EFC time received.
If an EFC (Expect Further Clearance Time) has not been received…
Commence descent and approach as close as possible to the ETA time filed or amended.
When the Clearance Limit is not a point from which an approach begins:
If an EFC (Expect Further Clearance Time) has been received…
Leave clearance limit at EFC time and proceed to a fix from which an instrument approach begins.
If an EFC (Expect Further Clearance Time) has not been received…
Leave the clearance limit and proceed to a fix from which an approach begins. Then commence descent as close as possible to ETA.
What is an MCA?
MCA’s are specific to the direction of flight being flown.
MCA are established to allow terrain clearance along a route.
what is an MRA?
They are established to pick up off-route VOR’s.
IFR malfunction reports
In each report required by paragraph (a) of this section, the pilot in command shall include the -
(1) Aircraft identification;
(2) Equipment affected;
(3) Degree to which the capability of the pilot to operate under IFR in the ATC system is impaired; and
(4) Nature and extent of assistance desired from ATC.
what are the stages of a thunderstorm?
developing
mature
dissipating
what are the 3 types of icing
clear
rime
mixed
clear ice
forms when large drops hit the aircraft and freeze slowly. It looks just like it sounds: clear.
rime ice
forms when small drops hit the aircraft and freeze rapidly. It usually looks like super thick frost. Milky white.
mixed ice
a mixture of clear and rime ice.
radiation fog
radiation fog forms when the ground cools, subsequently cooling surrounding air to its dew-point.
advection fog
When moist air moves over cooler ground or water
steam fog
steam fog forms when cold and dry air moves over warm water.
upslope fog
As moist, stable air moves up along terrain, it cools.
precipitation fog
As warm rain falls through cool air, the precipitation saturates the cool air.
freezing fog
occurs when tiny droplets of water are supercooled in the air
