which operation you have be in IFR flight plan and act clearance needed
Entering controlled airspace when IMC conditions exist
Altitude that DME is required
at or above FL24
When IFR is required?
Class E when IMC exists or in Class A airspace
Holding pattern timing

1 minute
1.5 minutes
Up to 6000’ MSL – 200 KIAS
6001’-14,000’ MSL – 230 KIAS
Above 14,000’ MSL – 265 KIAS
200
230

Lost communications procedure
Altitude to fly
M – Minimum altitude prescribed for IFR
E – Expected (e.g. “expect 5000ft after 10 minutes”)
A – last altitude Assigned by ATC
A.V.E.F – select route by the following order:
A –Assigned route, if none:
V –Vectored (fly to the fix/route/airway last vectored to), if none:
E –last Expected route by ATC, if none:
F – Filed route
Is the clearance limit a fix from which an approach begins?
Yes: Start descent and approach as close as possible to the EFC, or ETA (if no EFC given)
NO:At EFC or clearance limit (if no EFC given), proceed to a fix from which an approach begins and start the approach
What is the formula When a VDP is not published you can use this formula to calculate it:
VDP (in NM from threshold) = HAT/300, or
10% of HAT = seconds to subtract from time to MAP
two approach clearances
Contact approach
Visual approach
What is Contact approach?
Must be specifically requested by the pilot.(It cannot be initiated by ATC)
Requires at least 1SM reported ground visibility and the aircraft to remain clear of clouds.
Available only at airports with approved instrument approach procedures.
What is visual approach?
Initiated by either ATC or the pilot.
Requires at least 1000’ ceiling and 3SM visibility. (IFR under VMC)
Pilot must have either the airport or the traffic to follow in sight.
When can you descend to next instrument approach
segment?
When cleared for the approach and established on a segment of a published approach or route.
Airborne VOR Check, OBS and OBS indicator should read
within 6 of the selected radial
VFR requirement Class G airspace when below 10,000 feet MSL and above 1,200 feet AGL
1 statute miles, and can stay 500 feet below, 1,000 feet above and 2,000 feet horizontally from clouds.
night time basic VFR weather minimums for Class G, E airspace below 10,000 feet MSL
3 miles; 1,000 feet above; 2,000 feet horizontal; 500 feet below.
alternate minimums for an airport with a precision approach procedure
600 foot ceiling and 2 miles visibility.
alternate minimums for an airport with nonprecision approach
800 foot ceiling and 2 miles visibility.
publication can the VOR receiver ground checkpoint(s) found?
Airport/Facility Director
ELT
Altimeter
Transponder check requirements for IFR
ELT: not required for IFR but needs to be check every 12months. Rest is 24 months
What reports are required of a flight operating on an IFR clearance specifying VFR on Top in a nonradar environment?
The same reports that are required for any IFR flight.
flying on an IFR flight plan
two-way communications radio failure in VFR conditions. Next step
continue VFR and land as soon as practicable.
what is the landing minimums at the selected alternate airport
The landing minimums published for the type of procedure selected.
What action should you take if your DME fails at FL 240?
Notify ATC of the failure and continue to the next airport of intended landing where repairs can be made.
FOr IFR, pilot needs to know about runways length
be familiar with the runway lengths at airports of intended use, and the alternatives available if the flight cannot be completed.
f the RVR is not reported, what meteorological value should you substitute for 2,400 RVR?
A ground visibility of 1/2 SM.
IFR, an aircraft must be equipped with transponder or clock.
a clock with sweep second pointer or digital presentation.
airborne VOR check
allowable tolerance between two indicators of a dual VOR system
Units are independent
4° between the two indicated radials of a VOR.
airborne, what is the maximum permissible variation between the two indicated bearings when checking one VOR system against the other?
4° between the two indicated bearings to a VOR.
Not radial!!!!
