IFR enroute Flashcards
What are the blue stars on high IFR chart?
solid blue: compulsory reporting point
hollow blue: non-compulsory reporting point
What is MAA
Maximum Authorized Altitude - highest altitude allowed on an airway
Low altitude IFR RNAV routes are printed in blue and identified by the letter “T” and a three digit number. Mileages, GPS MEAs, and magnetic reference bearings are included. What is required to fly these routes?
An IFR approved GPS is required to fly these R-NAV routes.
What does Minimum Enroute Altitudes (MEAs) tell me?
obstacle clearance requirements, assures a satisfactory navigation signal, and the identification of fixes on the airway.
What does Minimum Obstruction Clearance Altitudes (MOCAs) provide?
1,000’ obstacle clearance over non mountainous terrain, and 2,000 over mountainous terrain, within 4 miles of the centerline of the airway.
How often does the FAA issues a new set of en route charts every:
Every 56 days
How are low altitude IFR RNAV routes depicted?
Blue, and identified by the letter T with a three digit number.
If you are flying direct between fixes not on a published route, the minimum altitude you should fly is:
Off Route Obstruction Clearance Altitude (OROCA).
It Guarantees, NAV signal reception, radar coverage, or communications with ATC.
Victor airway altitude changes are indicated by:
Short crossbars on each side of the airway at a fix.
On the airport chart what does the T and A in the top left mean?
T: in the remarks section of an approach chart indicates either non standard take off minimums or special departure procedures.
A: deals with using the airport as an alternate.
How do you calculate your required rate of climb?
Divide your projected groundspeed by 60 to find your miles per minute and multiply that by the climb required
What is a Standard Instrument Departure (SID) chart?
It is a pre-planned and coded departure route making a clearance from an airport easier.
It is a published flight procedures followed by aircraft on an IFR flight plan immediately after takeoff from an airport.
What does I-HUB mean?
That the DME frequency is the same as the localizer frequency
As you approach your destination, some items to consider for your approach are: (6)
DA/MDA penalties due to altimeter settings, approach lighting systems, wind, frequencies, radar coverage, procedure turns.
To determine if an inoperative component affects the minimums for an approach:
Check the Inoperative Components or Visual Aid Table
Airports that display a black triangle symbol with the letter A at the top left of the approach chart tells you that:
It has different IFR alternate weather minimums. Go to the Terminal Procedures Supplement to find the necessary information.
If no alternate minimums are specified, the alternate minimums for a precision approach and non-precision approach are:
600’-2 miles for a precision approach, and 800’-2 miles for a non-precision approach.
You don’t need to select an alternate airport when flying IFR if the destination airport has an instrument procedure and weather is forecast to be one hour before to one hour after the ETA:
2,000 foot or greater ceiling and 3 statute miles visibility.
What are the fuel requirements in IFR flight?
fuel for the destination, the alternate, and then another 45 minutes.
