Flight Exercises

Question 1

How do you check wind on low recce of a confined space?

Answer 1

at 40 knots use strings on front of helicopter, and compare the ground speed with IAS to acquire wind velocity.

Question 2

Scanning procedure in autorotation

Answer 2

lookout-nose pitch, attitude, landing area
IAS-70-75 knots
RRPM 95-100%
Ball-centre

Question 3

Response to loss of tail rotor thrust in hover

Answer 3

roll off throttle into detent spring allow aircraft to settle
raise colletive to cushion landing

Question 4

list initial post take-off checks

Answer 4

IAS-60 knots
MAP-set for climb
Carb heat-Adjust as needed
Landing lights-On as required
Transponder Altitude encoding

Question 5

Hover checks

Answer 5

Call centre of gravity
T+P’s-in the green?
MAP-Read
RPM-Top of green?

Question 6

Final approach checks

Answer 6

Carb heat as reguired
RPM-Top of green
Area- clear
IAS- 60knots
AGL-300AGL

Question 7

Steps for responding to hydraulic failure

Answer 7

slow down -70knots
verify hydraulic switch on, if not restored switch to off
land as soon as practible

Question 8

how can you avoid collisions with powerlines

Answer 8

• watch for towers; you will not see wires in time
• fly over the towers not the wires
• scan higher terrian on either side of flight path
• maintian 500’ AGL during flight

Question 9

Define: Dynamic Rollover

Answer 9

occurs when landing gear contacts a fixed object forcing aircraft to pivot about the object instead of about its own centre of gravity
- cannot be corrected with full laterl cyclic input

Question 10

What is dyssmetry of lift?

Answer 10

unequal lift created between the advancing and the retreating blade caused by differing relative airflow on the blades

Question 11

If encountering a “low G’ condition how would you reload the rotor?

Answer 11

apply an immediate and gentle aft cyclic, avoiding any large cyclic movments

Question 12

how is a Magneto check performed

Answer 12

Checked at 70% RPM
max 7% drop in 2 sec
check both right and left magnetos

Question 13

procedure for forced approach

Answer 13

on recognition of situation immediatly
lower collective
establish an auto rotative profile,
turn into wind,
select a suitable landing area
mayday call
passenger breifing
-500'AGL open throttle allow Gov to take over
-raise collective to MAPgreater than 20" and overshoot to climb

Question 14

configuration for climbing right turn in IMC

Answer 14

60 knots 13* bank angle
60 knots for climb
rate 1 turn=(10%IAS) + 7=bank angle

Question 15

Checks before departing a confined area-

Answer 15

call- reserve power available and
where to land in case of emergency
-in confined area and after over the trees
