Q

What can students use to provide safety heights and terrain avoidance heights while enroute?

A

VNC and ONC: Spot heights or MEF
GPH 206: MOCA if on airway, or AMA
GPH 200: 100 nm safe altitude or 25 nm MSA from aerodrome

16
Q

What is not an acceptable source for terrain avoidance? Why?

A

JNC

It does not include towers and other info, only the highest point of land

17
Q

What is special regarding the MEF and safety heights?

A

1000’ needs to be added to the number, it only provides the height of the highest obstacle within the area.

18
Q

What is some useful information to pass to pilots regarding emergency navigation?

A 
Suitable QNH
Wind direction and speed
Types of approaches available
Fuel analysis
Airspace considerations
Flight profile recommendations
Position of high terrain
Distress or suitable frequencies
Etc ...
19
Q

What are some of the best ways to determine px when navigation is degraded?

A

Navaids
Radar
DR from last position

20
Q

The CT-142 Driftdown Table describes what?

A

The single-engine altitude you can expect to settle at with one engine at max power, one engine feathered, 0° flap and gear retracted

21
Q

What are the Driftdown Table entry arguments?

A

Weight and ISA Dev

22
Q

What are the entry arguments for the Single Engine Climb Ceiling Table?

A

Weight and ISA Dev

23
Q

What are the entry arguments for the Single Engine Cruise Performance table?

A

ISA Dev, Weight and Altitude

24
Q

What is the CT-142 Glide Ratio?

A

Glide ratio of 15:1

Meaning you move ahead 15 000’ for every 1000’ of altitude loss (or 2.5 nm for every 1000’)

25
Q

Review Questions

We have a dual engine failure at 20 000’. How far can we glide to an emergency A/D?

A

50 nm (based on a glide ratio of 2.5 nm per 1000’)

26
Q

Review Questions

Surface wind is 260M/ 45 kts. Would LaRonge A/D be a viable place to land in the event event of a non-critical emergency?

A

No, runway is okay but the crosswind component is over 36 kts

27
Q

Review Questions

Do the spot heights on the JNCs account for man made obstructions?

A

No

28
Q

Review Questions

What is the 402 Sqn allotted time window for emergency navigation?

A

One minute for bearing and distance, two minutes for safety height

29
Q

Review Questions

Along with one minute for bearing and distance and two minutes for safety height, what valuable information could an ACSO pass to pilots in case of an emergency?

A 
Suitable QNH
Wind direction and speed
Types of approaches available
Fuel analysis
Airspace considerations
Flight profile recommendations
Positions of high terrain
Distress of suitable frequencies
