Helo Flashcards
Name 5 helo limitations
- Visibilty
- Weather Conditions
- Fuel
- Weight
- Terrain
what does the Collective Pitch Control do and where is it located
located usually on the Pilots left, it controls the Angle of attack of the main rotor blades thus decreasing or increasing lift
what does the Throttle Control do and where is it located
located on the Collective Pitch control it increases or decreases main rotor blade RPM
what does the Anti-torque Control do and where is it located
located at the pilots feet (pedals) the anti torque controls control the angle of attack of the tail rotor
what does the Cyclic Control do and where is it located
located between the pilots legs (control stick) the pilots operates this with his right hand. The cyclic Control controls the angle of attack of each main rotor blade independently to provide for movement of the helicopter in the desired direction of travel
how do you safely approach a running helicopter
from the front only when directed by the pilot of aircrew
what is “ground effect”
Ground effect is a condition of improved
performance that a helicopter experiences
when operating near the ground
what is “in ground effect”
In Ground Effect (IGE) is the effect on the
performance of a helicopter caused by the
return of the rotor wash from the ground.
(IGE) occurs to its greatest
extent at approximately one-half of the rotor
diameter above the ground
what is “out of ground effect”
“Out of Ground Effect” is when the rotor wash is not affected by proximity to the ground.
OGE usually occurs when the
helicopter is more than one-half of the rotor
diameter above the ground.
what is “Translational Lift”
improved rotor efficiency
resulting from directional flight
What are the three helos we deal with
Ranger
Mustang
Fox
What is the “Deadman Curve”
its the “Height-Velocity” chart, which indicates
speeds and altitudes to be maintained so
that a safe autorotation may be made in the
event of a mechanical or electrical failure.
What is referred to as the “density altitude”
Its the effect to aircraft performance by humidity, temperature, and atmospheric pressure
What are the crash procedures for a ground crash
Visor down, sweep mic Snug Belts, Adjust PPE, Check gear Crash position (sit up, arms crossed, snug belts) Check physical location of seat buckle and door handle Confirm exit path is clear wait for signal from pilot/crew or all moving parts stop Batt OFF FUEL OFF ELT ON EXIT to 12Oclock if possible Assist others/headcount/triage Make Radio contact for help
Crash Procedures for water landing
Snug Belts, Adjust PPE, Check gear
Crash position (sit up, arms crossed, snug belts)
Check physical location of seat buckle and door handle
crack door prior to impact
count to 10
swim out, then up then to nearest shore
