Are you required to have a NAVAID available “over route of flight?”
Yes, available over the route and in satisfactory operating conditions.
What do you do when weather goes below minimums at an alternate airport en route?
Dispatch/Flight Release must be amended en route to include any alternate airport within fuel range of aircraft.
Under what Part number are approved authorized airports certificated under?
Part 139
No person may list an alternate airport in a dispatch release unless what conditions exist?
Weather reports/forecasts indicate that weather conditions will be at or above alternate airport weather minimums as specified in the Operation Specifications at the ETA
What is the only condition that a PIC may allow a flight to continue toward any airport dispatched, when is the opinion of the PIC/Dispatcher that the flight cannot be completed safely?
When in the opinion of the PIC “there is no safer procedure” continuation is an emergency situation
What are standard IFR takeoff minimums?
Two engines or less = 1 SM or RVR 5000ft

Which is controlling, RVR or visibility in SM?
RVR shall be used when available
Which is controlling Rollout, midfield, or TDZ RVR?
TDZ RVR
What is the lowest takeoff minimum?
Two engines or less = RVR 5000ft
More than two engines = RVR 2400ft
What must the PIC do if an engine fails or rotation is stopped?
Land the aircraft at the nearest suitable airport where safe landing can be made
Are there exceptions to this rule?
