Obstruction clearance 1,000’ & 2,000’ mountainous area
MEA
Minimum Enroute IFR Altitude
Assures acceptable nav signal coverage & obstacle clearance between fixes
MOCA
Minimum Obstruction Clearance Altitude
Displayed like MEA with a *
Assures obstacle clearance requirements between two radio fixes & acceptable nav signal within 22 NM of a VOR

Instrument Flight definition
Control of an A/C spatial position by using instruments rather than outside visual reference.
Basis of helicopter control IFR
Proper instrument interpretation
Three fundamental skills of IFR
Cross Check

Radio class code ranges
HA, L, T
HA & L: 40 NM

Drift Correction procedure
- Initial Correction: 20 deg if >= 90 KIAS, 30 if below
- First trial: 10 deg
- If too small: repeat initial correction, 2nd trial with 15 deg
If too large: turn parallel to desired track, 2nd trial with 5 deg
Intercept Radial procedure
- Find direction to turn to: shortest way from desired track to the tip of the pointer
- Turn to 45 deg (90 deg for expedite) from the desired track
CDI full deflection value for LOC, VOR, GPS
LOC: 2 deg
VOR: 10 deg
GPS: Enroute 2 NM
Terminal 1 NM
Approach 0.3 NM
