Q

Departure clearance will meet obstacle clearance requirements and ar based on the premise that on departure the aircraft will?

A
  • cross at least 35’ above the departure end of the runway
  • Climb on runway heading to 400’ AAE before turning
  • maintain a climb gradient of at least 200’ per NM throughout the climb to a minimum latitude for enroute operations

Q

Visual approach

A
  • can be initiated by pilot or ATC
  • ceiling must be MRVA plus 500’ (min radar vector alt)
  • vis 3 SM or greater
  • pilot must have airport or traffic in sight to maintain visual separation
  • Wx is at least VFR as no missed approach will be issued
  • pilots responsibility for wake turbulence separation, noise abatements and any other restrictions
  • in the event of a missed approach, climb runway heading and listen for instructions

Q

Windshear - into an increasing Windshear

A

Increasing performance Windshear

  • increasing headwind produced more lift AC becomes high on glide path. POWER REDUCTION required to re-establish on GP
  • Once re-established, POWER INCREASE to maintain GP
  • ground speed is reduced; sink rate reduced
16
Q

Windshear - into a decreasing windshear

A

Decreasing performance Windshear

  • decreased headwind produced less lift and AC becomes low on glide path. POWER INCREASE is required to re-establish on GP
  • Once re-established, POWER DECREASE required to maintain GP
  • ground speed is increased; sink rate increased
17
Q

Headwind on inbound leg - greater than one min in

A

Reduce outbound leg by 3/4 of the error

18
Q

Tailwind on inbound leg - less than one min inbound

A

Decrease outbound leg by 4/3 of error

19
Q

Inbound RMI intercepts

A

Course - head - cut

Q

Outbound RMI intercepts
