- within 4NM of course
For a VOR check at a VOT, with CDI centered, what should the OBS read?
- 360 degrees, FROM
- or 180 degrees, TO
How do you check a VOR on surface?
- Set OBS to designated radio (AF/D)
- the CDI must center with a +/- 4 degrees
- FROM indication
What are the weather minimums to list an IFR alternate airport that has VOR approach only?
- Ceiling 800 feet
- Visibility 2 miles
What are the visibility and cloud clearance for a flight under Special VFR daylight, under 1200ft AGL?
- For special VFR under 10,000 feet
- visibility: 1 mile
- maintain clear of clouds
Before conducting an IFR flight the PIC should know all available information of a flight including what?
Runway lengths at airports of intended use, and the aircraft takeoff and landing data
When is an alternate airport required to be listed on a flight plan?
If the airport of intended landing has a
- ceiling below 2000 feet
- visibility less than 3 miles
- from 1 hour before and 1 hour after of intended ETA
Aircraft operated under IFR are required to have in addition to the equipment required for VFR and night
A slip skid indicator
When flying VFR on top, If you receive this clearance and fly the course of 180°, at what altitude should you fly?
maintain altitude or flight level appropriate for VFR flight. A magnetic course of 180° – 359° and above 3000 feet AGL, any even thousand foot MSL alititde +500’ would be appropriate
What is the maximum tolerance of a VOR check in the air AND on the ground?
- * +/-4° for a VOR ground check.
- * +/- 6° is the maximum tolerance for airborne VOR check
In class G airspace, more than 1200 feet above the surface but less than 10,000 feet MSL, during the day, vfr fight visibility is what
- one statute mile visibility
- cloud clearance of 500 feet below
- 1000 feet above
- 2000 feet horizontal
At what cabin pressure altitude can a pilot fly for longer than 30 minutes without using supplemental oxygen?
12,500 feet
- The minimum flight crew must use supplemntal oxygen after 30 minutes at cabin pressure altitudes above:
- 12,500’ MSL up to and including 12,000’ MSL.
When making an AIRBORNE VOR check, what is the max tolerance between TWO indicators of a DUAL VOR system?
4 degrees between the two indicated bearings of a VOR
What record is taken during an VOR check in the aircraft log or other permanent record by a pilot?
- The date
- place
- bearing error
- and signature
When using a VOT for VOR check, the CDI should be cenetered and the OBS should indicate what?
- 360 radial
- With the VOT tuned in, the CDI should center with an OBS setting of
- 360 degrees FROM
- 180 degrees TO
If the RVR equipment is inop for an IAP that requires 2,400 RVR, how should you expect the visibility requirement to be reported?
As a ground visibility of 1/2 SM
Under what conditions are you not required to list an alternate airport for an IFR flight plan? IAP in use at the airport
When the weather reports a
- ceiling of 2,000 feet
- visibility 3 miles
- 1 hour before and 1 hour after ETA
What is the visiblity and cloud clearance operating in CLASS E airspace at 9,500 ft MSL with a VFR on Top clerance in daylight?
- 3SM vis
- 1000ft above
- 500 ft below
- 2000 ft horizontal
For CLASS E airspace, les than 10,000 feet MSL, the VFR flight visibility is “3/1/5/2”
For Class E airspace for flight ABOVE 10,000 feet, VFR on top during daylight, what is the cloud and vis requirements?
- 5SM vis
- 1000 above
- 1000 below
- 1 mile horizontal
Where is DME required under IFR?
At or above 24,000 feet MSL if VOR equipment is required
What minimum navigation equipment is required for IFR flight?
Navigation equipment appropriate to the ground facilities to be used
While airborne, what is the maximum tolerance variation between the two indicate bearinces when checkng one VOR against another?
4 degrees betwen the two indicated bearings to a VOR
What is the minimum in flight visibility and distance from clounds during special VFR dayight hours BELOW 1,200 feet AGL?
- 1 mile visibility
- clear of clouds
When departing an airport located outside controlled airspace during IMC, you must file an IFR flight plan and receive a clerance before when?
Entering Class E airspace
