Cross Country Flight Planning Flashcards
3 common ways to navigate?
Pilotage- visual landmarks
Dead reckoning- computing direction
Radio navigation- use of radio aids
What types of charts are available for VFR?
Sectional charts- slow to medium aircraft
VFR Terminal Area Charts- Class B charts
VFR Flyway Planning Charts
Define: Isogonic Line
Connects points of equal magnetic variation
-dotted magenta line on sectional
Define: Magnetic Variation
The angle between true north and magnetic north
How do you convert true direction to magnetic direction?
Add west
Subtract east
Define: Magnetic Deviation
Because of magnetic influences in the airplane the compass needle is frequently deflected.
-use the card in the aircraft to calculate correction
What are radio aids to air navigation?
NBD- non directional radio beacon
VOR- very high frequency onmi-directional range
VORTAC- VHFVOR / Tactical Air Navigation
DME- Distance measuring equipment
What is a VOR/VORTAC?
VHF radio stations that project radials in all 360 degrees
What frequency range do VORs operate?
108-117.95
Define: VOR Radial?
Line of magnetic bearing extended from an omni-directional range
How are VOR NAVAIDs classified?
Terminal (T) - 25 mile range
Low (L) - 40 mile range
High (H) - 40+ mile range
What are VOR reception limitations?
Subject to line-of-sight limitations
What are different methods for checking VOR accuracy?
VOT check: +/- 4 degrees Ground checkpoint: +/- 4 degrees Airborne checkpoint: +/- 6 degrees Dual VOR check: 4 degrees between each other Radial over ground point: +/- 6 degrees
Define: DME
Distance Measuring Equipment
-used to measure the slant range distance of an aircraft to the DME navigation aid.
Define: GPS
Satellite-based radio navigation system that broadcasts a signal used by receivers to determine a precise position.
What are the 3 functional elements of GPS?
Space element- 30 satellites
Control element- network of ground based GPS monitoring/control stations that ensure accuracy
User element- consists of antennas on-board aircraft that provide positioning and precise timing.
What is the purpose of RAIM?
To ensure adequate GPS signals are being received at all times.
Where can a pilot receive RAIM availability info?
FSS during pre-flight.
Define: VFR Waypoint
Provides navigation aids for pilots unfamiliar with the area.
Define: DF Guidance
Given to aircraft in distress or to other aircraft that request it.
What is the most common type of radio equipment?
VHF
118.0 - 136.975
What is the VHF emergency frequency?
121.5
It is guarded by military/civil towers, FSS and radar facilities
What are the ground control frequencies?
121.6 - 121.9
Define: CTAF
Common Traffic Advisory Frequency
Define: UNICOM
Non-governmental communication facility which may provide airport information.
Define: ATIS
Automatic Terminal Information Service
If operating into an airport without a tower, FSS, or UNICOM, what is the procedure?
MULTICOM on 122.9 and self announce
Define: RCO
Remote Communications Outlet
-unmanned comm facility remotely controlled by ATC personnel that provides ground to ground comms between ATC and pilots at remote airports.
How can a pilot determine what frequency to use to activate a flight plan once airborne?
As the FSS briefer
Consult the AFD
If an in-flight emergency requires immediate action by the pilot what authority/responsibility does the pilot have?
The PIC is directly responsible and has final authority for operation of the aircraft.
A pilot may deviate from any rule in Part 91.
Pilots who deviate rules must send a written report upon request to the administrator.
Is pre-flight action required for a local flight?
Yes. Pilots must familiarize themselves with all available information concerning the flight, including:
- runway lengths
- takeoff/landing distance data
What should pre-flight for flights away from the airport include?
Weather reports Fuel requirements Alternatives ATC traffic delays Runway lengths and takeoff/landing distance data
If operating an aircraft in close proximity to another, what regulations apply?
No person may operate so close to another aircraft as to create a hazard.
Formation flight has to be agreed upon by all pilots involved.
No formation flight if the flight is for hire.
What is the Right of Way order?
Balloons Gliders Airships Aircrafts Rotorcrafts
