When approaching a non-towered Airport for landing, how far away should you begin to monitor and communicate as appropriate on the CTAF Frequency?
10 miles out
What is Radar Traffic Information Service?
A radar service (also called “flight following”) provided by ATC to alert the pilot to other traffic in their Area
Should you use Radar Traffic Information Service
Yes, not mandatory
What is a Terminal Radar Service Area (TRSA)?
Areas where participating pilots can receive additional radar services which have been redefined as TRSA Service
How would an Army aviator participate in a TRSA?
Contact radar approach control and avail themselves of the TRSA Services
Can an Army pilot flying an Army helicopter legally enter a Restricted Area VFR?
yes, with authorization from the using or controlling agency first
What is the purpose of a Warning Area?
to warn nonparticipating pilots of the potential danger from activity that may be hazardous to nonparticipating aircraft
There are no restrictions on through flight for VFR aircraft flying in a Military Operations Area (MOA). What procedure should be followed prior to entering an MOA?
Pilots shoukd contact any FSS within 100 miles of the area to obtain accurate real-time information concerning the MOA hours of operation. Prior to entering an active MOA, pilots should contact the controlling agency for traffic advisories
What is the purpose of an Alert Area?
To inform nonparticipating pilots of areas that may contain a high volume of pilot training or an unusual type of aerial activity
How could an Army aviator become aware of a possible Temporary Flight Restriction (TFR) along the route of flight?
NOTAMS
Would providing a safe environment for the operation of disaster relief aircraft be a possible reasin to create a TFR?
Yes
True Course
Angle measured clockwise from True North to the proposed flight path.
Line from Point A to Point B
Markings on Course Lines
Tick marks every 10 NM (Labeled every 20 NM)
Visual Checkpoint every 15 NM
Survey of Course Line
- Highest MEF
- Elevation of highest Terrain
- Obstructions
- Classes and types of Airspaces
- Emergency Airfields
4 NM in every direction
Drift correction
Correction for Wind
Track
Actual flight path over ground measured clockwise from True North.
If you fucked up and you get drifted away from TC
True Heading
Angle measured clockwise from true north to the nose of the a/c.
TC +- DC = TH
Point your nose in that direction
Drift Angle
Angle between True Heading and Track
Shows you how much you fucked up
Ground Speed
Your real speed over ground
TAS +- Wind = GS
Magnetic Variation
Angular Difference between true and magnetic North
Agonic Line
Line connecting points of Zero Variation
Isogonic Line
Line connecting points of equal magnetic variation
Magnetic Heading
Angle Measured from magnetic north clockwise to nose of A/C
Substract Eastern Variation
Add Western Variation
Complete Formula
TC +- DC = TH +- VAR = MH
