Q

After Takeoff, you attempt to activate you VFR flight plan but are unable to contact the FSS. What will happen to your filed flight plan?

A

Plan remains active until activation, or for 1 hour following estimated departure time. After that it is cancelled.

Q

Diversion/Alt1: What actions should be taken if you become disoriented or lost on a X-Country flight (NO GPS AVAILABLE)

A

5 C’s:
1. Climb - better visibility, better radio range
2. Circle - don’t make things worse by continuing in an unfamiliar direction
3. Communicate - Approach, Center, tower. Use 121.5 if no results on others
4. Confess - let them know your problem
5. Comply with instructions

19
Q

During a X-Country flight, weather has deteriorated, and you must Divert to an alternate Airport. Assuming no GPS and NO DME available, how will you navigate to the alternative?

A
  1. Call the Tower and ask for vectors
  2. Call approach or control and ask for Vectors
  3. User localizer or Triangulate using VOR
  4. Use Chart - Plot approx Mag course from nearby VOR compas rose or flyway
  5. Dead-reckon your way based on chart
