the airport elevation to figure density
altitude and your airplanes performance.

A 10% change in aircraft weight will result in a
20% change in the takeoff distance required
source; Mountain Flying Bible
Short field takeoff advice from the late Sparky Imeson, noted mountain flying expert;
If you have not reached 70% of your takeoff speed ½ way down the runway, ABORT!
Also, make sure the parking brake is OFF!
winds are magnetic
100 pounds below max gross weight
Verify this in the P.O.H.
74 + 12 = 86 suggested for cruise climb.
P.O.H. shows 70 – 85Kts for cruise climb
the Engine, Kas Thomas
The ‘iceT’ formula; indicated ~ calibrated, equivalent (applies to jets), True Airspeed. TAS increases with altitude. Indicated will decrease with altitude due to less dynamic pressure in the Pitot tube
x TAS multiple (60=1, 120=2, etc)
= crosswind component
Ie., @ 120 knots, each degree of crab is caused by a 2 degree x-wind component resulting in a ‘x’ degree drift correction.
Ex., 5 degrees left x 2 = 10 knot cross wind
pilots use this technique.
10 min to fly 25NM; 10x6=60; 6x25 = 150 kts
Or, use this to figure the altitude to be at a given distance from a runway…for a stabilized
