IFR Stuff Flashcards
RVR?
Rwy visual Range - the visibility determined for a particular runway by a transmissometer.
FEET (SM)
1600 1/4
2400 5/8
3200 3/4
4500 7/8
5000 1
6000 1 1/4
What is considered Runway Environment?
REIL
Papi/Vasi
Lightning approach systems
Rwy
RWY markings
Rwy Lights
Threshold

Touchdown zone or markings
Holding speeds
6000 and below 200kts
6001 - 14,000 230 kts
14,001 above 265 kts
DP’s
Departure procedures - Are preplanned graphical/textual routes from airport that provide obstacle clearance while reducing communication and departure delays
2 types:
ODP & SIDs found in the Terminal Procedure Publications.
SID’s
Standard instrument Departures-
ATC procedures printed graphically for pilots. provides obstacles clearance and a transition from terminal area to en route. Designed for system enhancement and reduce pilot workload.
Pilot nav SIDs - provide your own nav. With minimal radio communication.
Radar Vector SIDs - ATC provides Radar Vectors just after take off.
MEA
Minimum Enroute Altitude
Lowest published Altitude between radio fixes that ensure acceptable radio navigation signal and obstacles clearance.
MOCA
Minimum Obstruction Clearance Altitude - lowest published altitude between radio fixes on VOR airways, off airway routes or route segments that meet obstacles clearance requirements and acceptable nav. Signal coverage only with in 25 sm (22nm) of a VOR.
MCA
Minimum crossing Altitude
Lowest altitude at certain fixes at which aircraft must cross when in the direction of higher MEA.
MRA
Minimum reception Altitude
The lowest altitude at which an interception must be determined from an off course NAVAID.
MAA
Maximum Authorized Altitude
Max usable altitude for an airspace structure or a route segment that ensures adequate reception of nav aid signals.
OROCA
Off Route obstruction clearance Altitude
Provides obstruction clearance with a 1000 foot buffer in non mountainous terrain areas and 2000 Foot buffer in mountainous terrain. Might not provide signal coverage from Ground based nav aids, ATC radar or communications coverage.
What must be reported to ATC?
Missed Approach
Airspeed change - +-10kts or 5%
Reaching a holding fix
Vacating altitude
ETA change more than 2 mins
Leaving assigned holding fix
Outer marker inbound
Unforecast weather
Safety of Flight compromised
VFR On top: Altitude change
Final Approach inbound
Radio/coms malfunction
Compulsory fix
500 FPM Climb/decent unable
RAIM?
Receiver Autonomous Integrity Receiver
Satellites that remove any single error positioning from the majority of satellites that say you’re in the same position.
WAAS
Wide Area Augmented System
Designed to Improve Accuracy, Integrity, availability of GPS Signal by using Measurements from the reference stations are sent to master stations, which queue the received Deviation Correction (DC) and send the correction messages to geostationary WAAS satellites in a timely manner (every 5 seconds or better).
What does the airplane need to be equipped with for IFR Flight?

What do you do when Lost comms?
-Check the last freq., your volume and check your Headset plugs. Still nothing 7600
Figure out:
Route -where to Fly?

(Which ever happened last)
Altitude- How high to fly?
Minimun enroute altitude

Assigned
(Which ever is higher)
maybe lost of alternator. Bigger problem. squawk 7700.
VFR-on-TOP
Permits pilots to select an altitude or FL of choice altitude where IMC does not exist.
Must fly:
-Appropriate VFR Altitude
-Able to see and avoid other traffic
-Comply with VFR visibility from clouds
-Comply with IFR
VFR Over-The-Top
A VFR operation in which the pilot maintains VFR cloud clearance requirements at all times while flying over an undercast layer.
Take off in VFR conditions- Over the clouds- to VFR destination.
No IFR clearance is required.
MSA
Minimum Safe/Sector altitude
Provides 1000 Ft clearance, but not assure Nav. signal.
