Instrument Navigation & Procedures
Maximum holding speed and time above 14,00msl
265 knots/ 1.5 minute legs
IFR Fuel Requirements
Fly to the destination, alternate (if required) + 45 minutes
During a static system blockage, the VSI will
Drop to zero
Use this to identify the FAF on a precision approach
Glide Slope intercept
Lightning bolt
The conditions required for a thunderstorm
Moisture
Unstable air
Lifting Action
The MEA guarantees this
Navigational signal coverage/ obstruction clearance
An alternate is required when
1-2-3
A full scale deflection on a VOR NAV receiver is this many degrees
10 degrees
An LPV approach requires this (something the LNAV approach does not)
WAAS
The type of ice that forms at the "warmer temperatures."
Clear ice
The four VOR tests are
VOT
Dual
Ground
Airborne
You must depart by this time. If unable, you must notify ATC within 30 minutes before they begin searching
Clearance void time
An example of aircraft deicing equipment
Pneumatic Boots
Bleed Air
Electro Impact
Electro Thermal
A pilot must go missed from a non-precision approach no later than this point
MAP
The atmospheres stability to resist vertical motion
Criteria to descend below DA/MDA
Continuous visual reference
Required flight visibility
Be in a position to make a normal landing
Standard alternate minimums
Precision: 600-2
Non-precision: 800-2
If no instrument approach: conditions allowing for a descent from MEA and landing under basic VFR
The turn coordinator operates on this principle
Precession
Do not begin to circle to another runway until these criteria are met
FAR 91.175
Inside the protected area
Sigmets are valid for
4 hours
Acronym for required reports to ATC when operating under IFR in both radar and non-radar environments
MARVELOUS VFR C500
Required equipment for IFR night
ATOMATO FLAMES
FLAPS
GRABCARD
An aggressive nose down movement on short final when flaps are brought full when in known icing conditions is an indication of this
Tailplane Icing
The missed approach procedure requires a climb gradient of 404 ft/nm. The ground speed is 120 knots so the required climb rate is
807 ft/min
Often mistaken for UFO's (yes actually) this ominous type of cloud is caused my air being forced up terrain, causing turbulence
Lenticular
