Thrust PPL ground 11 stage 1

5 H adversely affecting performance

hot (same as humidity, high density altitude)

humidity (more viscous air, aircraft feels higher, adverse effect)

aircraft heaviness (heavy aircraft = subpar performance)

high altitude (subpar like heat)

headwind (subpar, lowers groundspeed)

density altitude is what your airplane (is at/feels like its at)

feels like its at

dentisty altitude is indicated altitude corrected for….

non-standard pressure

pressure altitude is what altitude airplane feels like it’s at at ____

29.92Hg

high density altitude improves/reduces take off performance and leads to a longer/slow climb and distance

reduces, longer

Pressure altitude formula

29.92 - altimeter setting for that day x 1000 + field elevation

Density altitude formula

current temp - standard temp at field elevation x 120 + PA

Where do you find take off distance?

in POH, with and without 50 foot obstacle option

feet per nautical mile conversion to feet per min

FPM = feet per nm x groundspeed / 60

on a performance sheet, you should underestimate/overestimate temp in order to plan for the worst

overestimate

asking for tabs means

17 gallons per side, 34 total

don’t EVER land in a (tailwind/headwind)

tailwind because there’s no laminar flow

what is our max demo crosswind component in the archer?

17 knots, but thrust tested it at 22. their test doesn’t count, though, so max demo is 17

coming in final on landing, you are operating in (reverse/normal) command

reverse (pitch for speed, power for altitude)

empty weight includes

airframe, engine, and all permanently installed equipment AND fuel/oil stuck in lines

Center of gravity

point of balance airline airplane’s longitudinal axis

Arm

horizontal distance in inches from datum line to the CG

Moment

measure of tilting force of an object

weightxarm = moment is expressed in

pounds-inches

center of gravity formula

total moment x total weight

everything you can do on the “whiz wheel,” you can also do on the

CX3/E6B

cold fronts are nice or crazy rain?

crazy rain! fast moving, lots of air disturbances

are dry lines on the side of the bumps or the other side?

the other side!

stationary fronts linger how many days?

3-5 (they have equal energy and linger)

P0022 means…

0.22 inches rain on the runway

FM050300

from the 5th day at 03:00 zulu time

9999 on a TAF means

visibility is 10+SM
