Route Limitation
The route must be within one hour flight time of a suitable airport in still air at normal cruising speed with one engine inoperative. Take-off alternates for the DHC-8-402 must be within 250 nm of the departure airport.
Minimum SAT for engine relight is

When using previously store flight plans and waypoints, the waypoints must
be verified for accuracy, by reference to current publication, prior to their use.
For wind speed greater than 8 kts, with the nose of the airplane more than 30 degrees out of wind, the maximum power for ground static operation is as follows
