Minimum En-route Altitude vs
Minimum Safe Altitude
MEA is min alt between two fixes ensuring terrain clearance and navaid coverage.
MSA is a more general term that allows you to determine an altitude for a phase of the flight to ensure terrain clearance.
RVR vs visibility
RVR is specific to the runway and takes into consideration runway lighting.
General visibility is usually lower.
Visual references required to pass DA/MDA
Main runway lights
LPV vs LNAV/VNAV
LPV uses augmented GPS system to establish point in 3d space and give 3d guidance to touchdown zone. NOT precision approach though.
LNAV/VNAV uses GPS data for the 2d approach (LNAV) and uses barometric data to generate 3d guidance.
Action on radio failure
Set 7600.
If VFR conditions continue flight under VFR and land ASAP.
Follow last clearance received, if not the filed route plan and aim to commence approach as close to the ETA as possible.

Take off alternate
- When required
- What is required
Required if landing minima not met at the departure aerodrome.
For 2 engine aircraft must be within 1 hours OEI cruise.
Destination alternate
- When required
- What is required
NOT required if VMC forecast for 1 hour either side of ETA.
Need 2 if weather conditions not satisfied at first one, distance must be considered in the fuel calcs.
