TD 95

Question 1

Note: Effective IIMC procedures are the result of detailed planning and disciplined execution. Multi-ship IIMC is especially hazardous and must be

Answer 1

thoroughly covered during ACBs

Question 2

Base Altitude (IIMC): This is the lowest altitude that provides obstacle clearance. If able add 1000’ (2000’ mountainous) to the elevation of the highest terrain or obstacle in AO. Base altitudes may change between checkpoints. If able,

Answer 2

use the highest/worst case altitude for simplicity.

Question 3

Stack-Up/Stack-Down (IIMC): this describes how aircraft are separated from front to rear. In a stack-up lead is at the _____________. In a stack-down lead is at the _________. Pre mission planning will dictate which procedure is utilized.

Answer 3

lowest altitude, highest altitude

Question 4

Standard heading adjustment for IIMC will be:

Answer 4

base +/- 10 degrees times chalk number

Question 5

Standard altitude adjustment will be:

Answer 5

base +/- 500 feet for subsequent chalks

Question 6

Any aircraft entering IIMC will announce

Answer 6

“Chalk #, heading, altitude, airspeed, altimeter setting”

Question 7

Any aircraft (in the formation) that can safely remain VMC will:

Answer 7

do so (dont scud run or conduct aggressive maneuvers to prevent from going IIMC)

Question 8

Lost visual contact while performing formation flight can be extremely hazardous. An aircraft in the formation that loses visual contact with aircraft to their front will immediately

Answer 8

decelerate to 10 KIAS less that the airspeed announced and coordinate altitude by climbing 200’ above or below

Question 9

Aircraft with which the visual contact has been lost will

Answer 9

announce heading, indicated airspeed, MSL altitude, distance, and bearing from a common reference point, and display appropriate trail aircraft lighting

Question 10

Once visual contact is regained, accelerate to an airspeed not more than ________ than the airspeed announced by the preceding aircraft to rejoin the formation and announce “closing”. When join up is complete, trail aircraft announces: ________

Answer 10

10 KTS greater, SADDLE

Question 11

IAW TC 3-04.4 lead changes are inherently difficult, potentially dangerous, and should be executed on the ground, whenever possible. A lead change is never initiated, day or night, by accelerating to overtake the lead aircraft. If a lead change must occur it will be initiated by the lead aircraft announcing:

Answer 11

“LEAD CHANGE RIGHT OR LEFT”

Question 12

Aircraft departing the flight makes a heading change of ________ and departs the formation. He maneuvers the aircraft o a minimum of ________ to the announced side.

Answer 12

30-90 degrees, 8 rotor disks

Question 13

The subsequent chalk will advise when the former lead has attained the proper separation. At that time, the former lead will adjust his flight path to parallel the formation and reduce airspeed by ______. As each aircraft in formation passes, they announce ___________

Answer 13

10 KIAS, “CHALK number, CLEAR”

Question 14

In most cases requiring a lead change, the former lead will assume trail position within the flight. If it is determined the former lead aircraft requires constant observation (due to malfunction, etc.) the AMC will direct position within the flight. The subsequent A/C will increase to a minimum of ________________. Subsequent aircraft will call the former lead “clear to rejoin” the formation in the position in front of subsequent aircraft allowing the former lead to rejoin the flight., Once complete, the trail aircraft will announce __________

Answer 14

10 rotor disks and reduce 10 KIAS, SADDLE # of A/C in the flight
