# Recheck Required
- commercial operations
- which airplanes you are able to legally fly
- Performance and Limitations
# Recheck Items From Previous
- Weather
- Airspace
- Engine
- Pressurization
## Incomplete
- Human Factors
- Performance and Limitations
- Aerodynamics
- Common vs Private Carriage
- holding out
- part 91 vs 135 operations
- optaining a operating certificate
- contract flying
# Notes
## Weather Information
- SIGMETs good
- AIRMETs good
- other items good
## Airspace
- good job
## Pressurization Systems
- asked about approximate time of useful consciousness at altitude (used 30,000 feet)
- I would work on your explanation of why this decreases exponentially
## Human Factors
- carbon monoxide poisioning: good
- hazardous attitudes: good
- fatigue: good
- decompression sickness: good job
- remember that in relationship to scuba diving there are mainly only AIM recommendations not regulations
- OTC medication
- save this [OTC Guide FAA](https://www.faa.gov/pilots/medical_certification/media/OTCMedicationsforPilots.pdf)
- remember that being hungover would qualify as being "under the influence of alcohol"
## Commercial Operations
- asked about flying a P210R
- got the endorsements correct
- ==**also stated that someone who has at least a PPL and was proficient in the airplane would have to sign off that you can fly that airplane**==
- remember that you can fly any airplane that is ASEL that does not require a type certificate without an endorsement for that specific make and model
- review the requirements for when a type certificate is required
- ==**currency is maintained for any ASEL that you fly assuming you are flying another ASEL**==
- you can fly a 150 / P210R without additional training assuming you have the required endorsements
- [ ] review what type ratings are for and when they are required, you are confusing yourself with this
- used scenario of dive shop owner raffling tickets to the public for trip and wants to hire you as the pilot for the trip
- stated that this would be a legal operation
## STC / Major Alterations
- used example of cessna cam
- was able to determine STC / redo weight and balance
- don't forget about form 337
## Performance and Limitations
- asked about FWD and AFT CG
- ==**stated FWD would be better because it would generate less drag and so you could fly faster**==
- [ ] review [Bold Method: Aft CG](https://www.boldmethod.com/learn-to-fly/performance/how-does-cg-affect-aircraft-performance/)
