Weather and pressure (density vs true altitude), Cloud base, freezing level, DALR, SALR, Surface heating

How to calculate Pressure Altitude Ref: https://www.youtube.com/watch?v=KcisGhtIigE Pressure Altitude definition: The height above the standard datum plane. (Sea level, 15 degrees, 29.92 in mercury, 1.98 degrees per 1000 ft, 14.7) Pressure Altitude Method 1: Set altimeter to 29.92 and read pressure Pressure altitude Method 2: ((29.92 - altimeter setting) * 1000) add this to:     Field elevation if you're trying to get PA on ground     Flight elevation (set to altimeter setting?) if you're trying to get PA in air Pressure altitude Method 3: (no need to memorize)      hAlt = (1-(pSta/1013.25)^0.190284) x 145366.45 True altitude: Setting the altimeter to altimeter setting approximates True altitude (actual altitude above sea level) Trough: a line that juts out from a low pressure area Ridge: Similar to trough but on a high pressure area, typically nice weather Col: area between two low and two high pressure areas creating unstable weather.

  Entering Maneuvering Area: (602.99) Report intention prior to entering the maneuvering area. Departure: (602.100) Before moving onto runway, your departure intentions, Before takeoff, ensure that there is no likelihood of collision, After takeoff, report departing the circuit. Reporting procedures on arrival: (602.101) At least five minutes before entering the area provide the aircraft’s position, altitude, ETA and arrival intentions, When joining the circuit, giving position, When on the downwind leg, (if applicable) When on final approach, When clear of the landing area. Flying continuous circuits: (602.102) Report joining downwind, State intentions when on final, When clear of the landing surface on final landing Flying through an MF area: (602.103) Report at least 5 minutes prior to entering the area, providing position, altitude and intentions, When clear of the area. https://tc.canada.ca/sites/default/files/2020-10/tp11541e-accessible_vfr_procedures_at_uncontrolled_aerodrom...

Enroute procedures

Image
Enrout e Procedures Opening Flight Plan Setting Heading Validate TAS Checkpoints Drift Correction Arrival Planning Opening Flight Plan VFR flight plans are not opened automatically   Must be opened by contacting FSS Departing CNY3, contact London FIC on 122.375 Ask to open VFR flight plan, tell them time off CNY3 (UTC) Takeoff Time + Filed EET = ETA Enroute Procedures Setting Heading Before crossing SHP: Cruise Checks complete Set power Lean mixture Set heading indicator (to match compass) Set heading bug (if equipped) Overhead SHP: Turn on course  Mark the time Note ETE/ETA – this doesn’t have to be done right this second, as long as you wrote down the time! Begin Departure Angle Check (check that we're on the correct heading, i guess?) Validate TAS (it's on the ASI!) This is under c26/c27 planning in the CFS: pg 1426, 1427

CFS, Reading

Image
 All the details on how to read the CFS are in the "Table of contents" in the CFS.  Here's the services details: PAPI, for CYKF: PAPI, for stratford: 3.5 or other angle means there is definitely papi, but at a non standard angle.  P1, P2, P3 and AP means PAPI and is associated with each runway. What is TE?

Headings & altitude

 Variation: change from the isogonic lines on a map Deviation: change from the airplane's compass error Magnetic true - used for altitude determination in south airspace True track - used for altitude determination in northern airspace 0-179 is East 180-359 is West Cruising altitudes don't kick in until 3000 AGL

Altitude calculations

 We begin with the Altimeter setting, from AWOS eg: Alt setting: 29.82 Field Elevation: 1051 29.92 is the 'standard' Altimeter PA - Pressure Altitude is what you'd read on the altimeter in your plane if set to 29.92.  You can also calculate it: (Standard Pressure - AWOS pressure) * 1000 + Field Elevation = PA (29.92 - 29.82) * 1000 + 1051 = 100 + 1051 = 1151 PA: 1151 The PA assumes a lapse rate of 1.98 for the pressure from Field elevation to Sea. Density Altitude - DA is PA adjusted for temperature Most POH's use DA in their takeoff & landing calcs           Density Altitude is the best predictor of aircraft performance Solved on the E6B in the right window This calc assumes dry air, moist air makes it lower!           A: Use E6B with temp and PA - on right line the temp up with the PA, then read DA Absolute Altitude - Exact height of airplane above terrain Misc: Station pressure - weight of column of air a...
