Formulas Flashcards
Distance to station
GS * Time in Min / degrees of bearing change = distance to station
VHF reception distance
1.23 ✔️alt = VFR reception distance
Alt=aircraft altitude above the station
Max payload
Max payload = MZFW - BOW
MZFW = max zero fuel weight BOW = basic operating weight
Center of gravity shift
w/W = d/D
w = weight of object to move W = gross WT of aircraft d = number of inches that the C of G must be moved D = distance between cargo compartments
Distance to critical point
D*Hr / Or+Hr=distance to critical point
D = total trip distance Hr = reduced or 3 engine ground speed home Or = reduced or 3 engine ground speed out
Specific air range
TAS / fuel flow = specific air range
Specific ground range
Ground speed / fuel flow = specific ground range
Mach number
TAS/S = Mach number
S=speed of sound at flight temp
Angel of bank for rare one turn
TAS/10 +7= angle of bank for rate one turn
Stall speed of an A/C executing a banked turn
Normal stall speed *✔️load factor = Stall speed of an A/C executing a banked turn
60 degree = 2G
45 degree = 1.4G
Hydroplaning speed
Hydroplaning speed = 7.7✔️tire PSI
Non rotating tire
Hydroplaning speed
Hydroplaning speed = 9.0✔️tire PSI
rotating tire during take off
Port drift
True altitude is increasing
Starboard drift
True altitude is decreasing
