Focus Items Flashcards
Factors affecting stall speed?
- WEIGHT: need more lift = higher AOA
- LOAD FACTOR: bank = less vertical lift
- POWER: upward thrust vector adds to lift & slipstream helps generate lift
- CG: forward CG = need more tail down force = need more lift = higher AOA
- FLAPS
- ICE
- ALTITUDE: stall at same IAS but higher TAS
How much does stall speed increase at 2G (60 deg bank)?
40% (sqrt of 2)
Different airspeeds
- IAS
- CAS: IAS corrected for installation & instrument error (pitot tube has higher AOA)
- TAS: CAS corrected for altitude & nonstd temp
- GS: TAS adjusted for wind
- EAS: CAS corrected for compressibility
What’s load factor?
Ratio of Lift to Weight
When is Mode C requried?
- Mode C veil (30nm around Class B)
- Class B
- Class C and above
- Above 10,000 MSL (unless below 2500AGL)
- ADIZ (off coast)
VFR TO & LDG minimums
FAR 91.155(c)&(d)
- Class BCDE: 3 miles GND vis & 1000’
- Class G: 1 mile GND vis & Clear of Clouds
- SVFR: 1 mile GND vis & Clear of Clouds
Winds aloft
* 9900
* 7319
* 7799
- 9900 = light and variable
- 7139 = 230 @ 119
- 7799 = 270 @199+
Wind & temp excluded in Winds Aloft
- No wind for 1500 AGL
- No temp for 2500 AGL
- No temp for 3000 MSL
What’s the 3-6 rule?
-
ALT to lose in 000’ x3 for TOD
(5500-1200=4300 –> 4.3x3=13NM) -
GSx6 for descent rate
(160x6=960 FPM)
Cantilever wing
A wing that uses no external struts or bracing
What’s adverse yaw
the tendency of an airplane to yaw in the opposite direction of the turn
What’s a commercial operator?
A person who
* for compensation or hire
* engages in the carriage of persons or property
* by aircraft
* in air commerce
* other than an air carrier or foreign a/c
What requires immediate NTSB notification?
(AIM 7-7-2)
Notify immediately an accident or any of the following incidents:
1. Flight control system malfunction or failure
2. Inabilityof required flight crew to perform normal flight duties due to injury or illness (i.e. heart attack)
3. Failure of structural components of a turbuine engine, excl. compressor, turbine blades and vanes
4. Inflight fire
5. Aircraft collide in flight
6. Over $25,000 damage to property other than aircraft
7. Overdue aircraft believed to be involved in an accident
For large ME a/c, what requires immediate NTSB notification?
(AIM 7-7-2)
For large ME aircraft (>12,500 lbs MTOW), notify immediately:
1. Inflight electrical system failure that requires sustained use of backup power
2. Inflight hydraulic system failure that requries sustained use of remaining system for movement of flight control surfaces
3. Loss of power by two or more engines
4. Evacuation with use of emergency egress system
NTSB: What’s an accident?
(49 CFR Part 830)
an occurrence
* associated with the operation of an aircraft
* that takes place between the time any person boards the aircraft with the intention of flight and all such persons have disembarked, and
* in which any person suffers death or serious injury, or
* in which the aircraft receives substantial damage
NTSB: What’s substantial damage?
Damage or failure that:
* adversely affects the structural strength, performance, or flight characteristics of the aircraft and
* would usually require significant repair or replacement
NTSB: What’s not considered substantial damage?
- Engine failure or damage limited to an engine if only one engine fails or is damaged
- Bent fairings or cowling
- Dented skin
- Small punctured holes in the skin or fabric
- Ground damage to rotor or propeller blades
- Damage to landing gear, wheels, tires, flaps, engine accessories, brakes, or wingtips
NTSB: What’s serious injury?
any injury that
1. hospitalized for more than 48 hours, within 7 days;
2. fracture of any bone (except simple fractures of fingers, toes, or nose);
3. severe hemorrhages, nerve, muscle, or tendon damage;
4. involves any internal organ; or
5. involves 2nd/3rd degree burns, or any burns affecting more than 5% of body surface
When must a report be filed with NTSB?
- Within 10 day after an accident
- When an overdue aircraft is still missing after 7 days
- For an incident where notification is required, only as requested
