Question 1

Minimum weather criteria for all VFR operations:
(ceiling/visibility)
- VTOL/CONV (</= 80KCAS):
- VTOL/CONV (>/= 81KCAS):
- APLN (<60 Nacelle):
- Night Unaided (APLN/CONV/VTOL):

Answer 1

• VTOL/CONV (</= 80KCAS): 1sm clear of clouds
• VTOL/CONV (>/= 81KCAS): 500 / 2 sm
• APLN (<60 Nacelle): 1000 / 3 sm
• Night Unaided (APLN/CONV/VTOL): 1500 / 3sm

Question 2

ESA - what is it and how to do you compute it?

Answer 2

Emergency Safe Altitude:
- provides positive terrain clearance in IMC needed to exit the low-level environment

• add 1000 ft (2000 ft in mountainous terrain) to the highest obstacle/terrain feature within 10nm of route centerline or intended flight path
  (rounded up to the next 100-ft increment)

Question 3

MSA - what is it and how do you compute it?

Answer 3

Minimum Safe Altitude:
- provides terrain clearance and limited threat avoidance if interruption of low-level operations is necessary

• add 500 ft (or the planned SCP for TF ops) to the elevation of the highest terrain or obstacle within 3nm of route centerline or planned flight path
  (rounded up to the next 100-ft increment)

Question 4

What is considered low-level operations for APLN and VTOL/CONV?

Answer 4

• APLN : below 500ft AGL
• VTOL/CONV : below 300ft AGL

Question 5

Low-level sorties in mountainous terrain should be conducted no lower than:

Answer 5

• APLN : 200ft modified contour or 200ft SCP
• CONV : 100ft

Question 6

Mountainous Terrain is defined as:

Answer 6

• having a 500ft change in surface elevation in 0.5nm

Question 7

Aircrew will conduct a PAC when:

Answer 7

• OAT <20deg C
• MGT increases 30-40deg for the same Qm
• when indicated power available is less than calculated power available

Question 8

Power required for Vertical T/O and Landing Terminal Operations training:

Answer 8

Approach:
- clear escape route: OGE
- restricted escape route or potential LVA: OGE + 5%

Departure:
- clear escape route: 30ft hover power
- restricted escape route or LVTO: OGE
