3 conditions for settling with power?
-less than etl -at least 20% power -greater than 300fpm descent
OODA loop stands for
observation orientation decision action
DECIDE stands for
Detect-detect a change has occurred Estimate-estimate need to react Choose-which is more favorable Identify-identify theres change Do-do something Evaluate-evaluate the effect of what you did
PAVE stands for
pilot-physical and emotionl readiness aircraft-capable of task, within weight, enough fuel enViroment- how will weather affect DA external pressures-dont override good judgment, dont feel pressured
Lost procedures
-climb -conserve -communicate -confess -comply
For flights away from departure airport you must review what specific info.
-weather -fuel requirements -alternates I case flight can’t be finished -any traffic delays known by atc -runway lengths intended -takeoff/landing distance
What is SRM
Single pilot Resource Management Managing information for safe flight such as weather briefing, weight and balance, aircraft operating limitations, runway lengths, alternate routes, etc.
5 dangerous attitudes to have as a PIC
-antiauthority:follow rules -invulnerability:it could happen to you -resignation:I’m not helpless -macho:taking chances is foolish -impulsivity:think first, not so fast
What is dissymmetry of lift
One blade producing more or less lift than the other and do to forward momentum of air striking one blade one will always produce more than the other countering this by blade flapping
3 types of LTE
-main rotor disc interference -tail rotor vortex ring state -weathercocking
Low G conditions can cause what 3 things
-mast bumping -roll -cutoff tail boom
