# Oral Portion of Progress Check Passed - [ ] review AIM 7-1-6 - [ ] review when you can log an instrument approach or hold - [ ] review inflight aviation weather advisory - [ ] review reading wind barbs - [ ] review alternate requirements for GPS approaches at destination and alternate - [ ] review how GPS works - [ ] review autopilot limitations # Pilot Qualifications - review when you can log an approach / hold in actual conditions - otherwise good job # Weather Information - [ ] review AIM 7-1-6 - icing - good job - remember to review private pilot level weather information (this still directly applies to instrument flight and can often be overlooked for more complex topics) - when reading wind barb remember that the gust factor will be added to get the total wind, so if there is one small black line (5 knots) and one larger red line (10 knots) the wind would be 5 gusting 15 - ![[Pasted image 20250827080824.png]] - this would indicate wind is 5 knots gusting 15 from the north # Cross Country Flight Planning - remember that alternate requirements do not apply when you need to actually fly an approach -> these are for planning purposes only (ie if an approach says NA for alternate minimums there is nothing stopping you from flying it if it is available at your alternate when you are flying) - ==**WAAS is required to plan a GPS approach at destination and alternate airport, remember that RAIM would always be required if you don't have WAAS**== - ==**WAAS is required for LPV approach**== # Preflight Procedures - don't forget about the defroster when thinking about icing conditions - pitot heat must be on when under 40F operating in IMC conditions (this is placarded on the airplane) # Aircraft Flight Instruments and Navigation Equipment - good job with pitot static / gyroscopic instruments - good job with VOR - good job with magnetic compass - good job with electronic flight display - [ ] review how GPS works - remember that GPS is a one way signal, there is no data that the GPS receiver has to send to the satellite - the important thing here is that the GPS satellite is broadcasting it's position and current time, and based on that the airplane is able to trilaterate its position - [ ] review [FAA GPS article](https://www.faa.gov/about/office_org/headquarters_offices/ato/service_units/techops/navservices/gnss/gps/howitworks) - [ ] review [GPS.gov GPS information](https://www.gps.gov/systems/gps/) - [ ] review [FAA: WAAS](https://www.faa.gov/about/office_org/headquarters_offices/ato/service_units/techops/navservices/gnss/waas/howitworks) - remember that you can use a WAAS satellite as one of your GPS satellites - [ ] ==**review autopilot limitations**== # Instrument Flight Deck Check - good job
