Basic I.F

Question 1

for straight and level flight what is the selective scan of instroments?

what are the remaining instroments to scan?

Answer 1

Attitude indicator - Altimeter - Attitude indicator - Directional indicator.

remaining introments to scan:

Airspeed indicator - turn coordinator (for level- blance ball). engine T’s + P’s - suction.

Question 2

In a climbing stage of flight what is the selective scan of instroments?

what are the remaining instroments to scan?

Answer 2

AAADA
(AI) Attitude indicator - Airspeed - (AI)attitude indicator - (DI) directiona indicator.

remainnig instroments to scan:
1. Altimeter
2. (VSI) vertical speed indicator
3. turn coordinator balance
4. engine T’s and P’s

Question 3

In a descending stage of flight what is the selective scan of instroments?

what are the remaining instroments to scan?

Answer 3

(AI) Attitude indicator - (VSI) vertical speed indicator - attitude indicator - (DI) directional indicator (AI)

remaining instroments to scan:
1.Altimeter
2. turn coordinator
3. engine instroments T’s + P’s

Question 4

In a turning stage of flight what is the selective scan of instroments?

what are the remaining instroments to scan?

Answer 4

(AI)Attitude indicator - Altimeter - (AI)Attitude indicator -** Turn co ordinator.** - (AI)Aittitude indicator

remaining introments to scan:
1. Directional indicator
2. Airspeed
3. Engine T’s + P’s

Question 5

Unusual attitude recovery technique for a high nose scenario.
(Dot on AI above artificial horizon line)

Answer 5

1. apply full power
2. then roll wings level
3. pitch down - with reference to the attitude indicator.(Dont pitch and roll simultanously)
4. once level wait for 90kts and then reduce pwr to 2300rpm

Question 6

What is the unusual attitude recovery technique for a low nose scenario

(dot on AI below the artificial horizon line)

Answer 6

1. **carby heat ON - Power to idle
2. ** roll wings level with reference to angle of bank on AI
3. as a seperate control input apply back pressure to straight + level attitude - referencing the dot on AI to horizon line.
4. then PWR to 2300rpm (normal cruise pwr)

Question 7

what is the procedure - workcycle making a change to maintain a stage of flight?

Answer 7

CCHAT - basic I.F reference change with the artificail horizon (AI)

• Change
• check
• Hold
• Adjust
• Trim

Question 8

What are the three sensory systems and what information do they give us

Answer 8

Vestibular System - inner ear cannal
- responsible for balance
- head position
Proprioceptive system
- tells you where your limbs are in space
Interoceptive system
- responsible for relaying information from inside your body

Question 9

What illusions might a pilot face.

Answer 9

-the ‘leans’ illusion-
when you feel as though the aircrat in slanted/banked but is actually level. your sensory system adapts to being on a diffrent angle and assumes that is new level.

discrepencies between sensory systems like sight and balance can cause:
- nausea
- Vertigo
- disorientation

-Somotogravic illusuion-

false sense of climbing when you put power in

-Inversion Illusion -
when you level off you get the sensation that you are still pitching up

-Graveyard spiral-
thinking you are straigth and level when you actaully turing and descending

-coriolis illusion-
when rolling you feel like you are rolling pitching and yawing all at once

Question 10

what course of action should you take if you fly into cloud (IMC)

Answer 10

1. use instromentd to keep straight and level
2. note current heading and pick a heading to turn to 180* current one
3. perfrom a co ordinated standard rate turn onto the new heading 180 from the current heading.
4. continue on heading until clear of cloud

Question 11

what is the formular for claculation a standard rate turn in degrees

Answer 11

(IAS divided by 10) + 7
= standard rate turn in degrees

(max angle of bank of 25*)
