Random Knowledge Flashcards
Static rolloverDynamic rollover3 requirements
-42-15-rolling moment, pivot point, thrust greater than weight
Blade stall:-indication-recovery steps
-vibration, nose pitchup, roll to left-lower collective, aft cyclic
Effective transitional lift is?
16-24knts helicopter will want to climbvortices are washed out causing rapid increase in lift
When does transverse flow effect occur?
14-20knts
Vibration Frequencies:-low-medium-high
-main rotor-engine-tail rotor
Airspeeds:-minimal drag-max range
-53-83
5 Compass errors?
-magnectic variation-magnetic deviation-magnetic dip-acceleration error(ands=accel north decel south)-turning error(unos=unshoot north overshoot south)
What is the standard lapse rate for temp and press?
-temp=-2c(-3.5f) per 1000 ft elevation increase-pressure=-1hg per 1000 ft elevation increase
What elements onboard interfere with the compass?
-metal components-engine-radios-electric accessories

3 conditions for settling with power?
-less than etl-at least 20% power-greater than 300fpm descent
OODA loop stands for
observationorientationdecisionaction
DECIDE stands for
Detect-detect a change has occurredEstimate-estimate need to reactChoose-which is more favorableIdentify-identify theres changeDo-do somethingEvaluate-evaluate the effect of what you did
PAVE stands for
pilot-physical and emotionl readinessaircraft-capable of task, within weight, enough fuelenViroment- how will weather affect DAexternal 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 ManagementManaging 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 othercountering 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
