IFR P1 Flashcards
Minimum enroute altitude (mea)
The lowest published altitude between radio fixes which assures acceptable nav signal coverage and meets obstacle clearance requirements for that altitude/fix
- obstacle clearance for route
-nav aid coverage for entire flight
Minimum obstruction clearance altitude ( moca)
Lowest published altitude in between radio fixes on VOR airways, off airway routes or route segments
-22 nm nav aid signal
-obstacle clearance
Off route obstruction clearance altitude (roca)
An off route altitude which provides an obstruction clearance within each bounded latitude/longitude
Non mountainous 1 mile clearance
Mountainous 2 mile
Purpose of IFR flight plan
Communicate pilots desire to ATC

3 degrees per second
Angle of bank needed to achieve standard rate turn?
15 degrees of TAS
90 knots or more initial correction and first trial numbers
Initial correction : 20 degrees

Holding procedures definition
A predetermined maneuver which keeps aircraft within a specified airspace while awaiting g g further clearance from ATC
Leg length :
The length of the inbound and outbound legs of a holding pattern can be measured two ways
-distance
-timing
Holding can be encountered in what 4 places?
En route
Arrival
In lieu of a procedure turn
Missed approach
ARPT ELEV
Airport elevation
Highest elevation on takeoff and landing surfaces
TDZE
Touchdown zone elevation
Highest point on first 3000 feet of runway
CTAF
Common traffic advisory frequency
Used when tower is closed making calls in the blind
MSA
Minimum safe altitude
(Only guarantees obstacle clearance)
Missed approach point (MAP)
Position prescribed in each instrument approach at which a missed approach procedure shall be executed if the required visual reference does not exist.
Aircraft approach categories
A : 90
B : 120
Copter : max 90 knots
