  <name>Before Takeoff Checks</name>
  <description>
This tutorial covers the before takeoff checklist. This involves the engine checks that are made in the run-up area just prior to taxiing to the runway and taking off.

For more information on the before takeoff checklist, see Section 2-11 of the FAA Airplane Flying Handbook available at http://www.faa.gov/library/manuals/aircraft/airplane_handbook/.
