Re: B737 Refresher Training
Suggested pattern for FSS preparation:
1) FCOM Normal Procedures (focus on learning scanflows)
2) Normal Checklist (from company or generic Boeing in QRH)
3) QRH Flight patterns (supplement by reading FCTM)
4) QRH non-normal procedures/flight patterns (supplemented by FCTM)
Keep it simple – it's like trying to drink from a fire hose – you can not swallow all so the challenge is know what's most important to get through the sim.
Systems depends on what nation you are in. (How theoretical?)
Use any study guides or CBTs tailored to written tests if applicable. Use FCOM volume 2 controls and indicator section to prepare for practical oral (typical FAA)
