What are standard alternate minimums?
Precision approach: 600’ and 2 miles visibility at ETA.
Non precision approach: 800’ and 2 miles visibility at ETA.
Visual approach: descent from MEA and approach and Landing done in VFR conditions.
Non standard: front pages of NOS, on airport diagrams
When must we file an alternate?
Always, except when within 1 hour before ETA to 1 hour after ETA, the weather is forecast to be 2000’ and 3 miles visibility.
If your airport of intended landing has only a GPS approach, you must file an alternate.
Recency experience requirements to act as PIC.
Conduct 6 instrument approaches, intercept and track navigational courses, and perform holding procedures. 6 months more before IPC is required. Safety pilot must be rated in the same category and class of aircraft with current medical. Passenger currency is the same 90 day rule. You may be instrument current but not to carry passengers. Night currency: 3 take offs and landings to a full stop, 1 hour after sunset to 1 hour before sunrise in same category, class and type.
To act as pilot in command of civil aircraft under IFR.
Pilot must have a current medical certificate and current instrument rating.
Logging instrument time.
Only for time when operating solely by instruments under actual or simulated.
An instructor may log time in actual instrument conditions.
Log location and type of approach and safety pilot.
A flight simulator may be used to log instrument time provided a authorized instructor is present.
Required documents.
Airworthiness certificate Registration Radio license Operating limitations (placards, POH) Weight and balance

WHAT ARE THE 3 DEFINITIONS OF NIGHT, AND WHAT ARE THEY USED FOR?
- Sunset (91.209) Beacons go on (plane and airport)
- Evening civil twilight: Generally 30 minutes after sunset (30 minutes before sunrise) this is used for logging night flight.
- 1 hour after sunset to 1 hour before sunrise (61.57b) This time is what we use for night currency.
INSTRUMENT DEPARTURES:
DP’s Departure Procedures: Either in front of NOS plates or right behind specific approach plates. Provides take off min’s and transition from airport to en route. Must have a textual description as a minimum in order to accept a Departure Procedure. If you don’t want a DP, write NO DP in remarks section on flight plan.
- If not given a DP, expect vectors from ATC until you are on course.
- Because we are part 91, takeoff minimums do not apply to us.
IFR CLEARANCE
C- Clearance limit R- Route of flight A- Altitude F- Frequency for departure T- Transponder code
CLEARANCE VOID TIME
Used by ATC when at an uncontrolled field. Somehow we need to get a release/clearance to depart, and if there is no tower, then we must:
- find a frequency that will work on the ground to talk to ATC.
- call from a cell phone and get a clearance void time.
- PURPOSE: to advise an aircraft that the departure clearance is automatically cancelled if takeoff is not made prior to a specified time. The pilot must obtain a new clearance or cancel his/her IFR flight plan if not off by the specified time.
CLIMB GRADIENT
- Some instrument departures will have a minimum climb gradient you must be able to achieve in order to execute the departure successfully
- This number is generally given in a foot/Nautical mile quantity
- We need to make this number tangible to us, so we change it to FPM on our VSI.
- To calculate: (Ground speed / 60 X Foot/NM requirement
EX: 100 KIAS / 60 = 1.6 X 300 Foot/NM=500fpm - So in this example, if we cannot obtain a 500’ / minute climb on departure, we cannot execute this departure procedure.
INSTRUMENT ALTITUDES
- 0-179 = odd thousands
- 180-359 = even thousands
- ONE: ODD NORTH EAST
MEA:
- MEA: Minimum En-route Altitude is the lowest published altitude between radio fixes that guarantees adequate navigational signal reception and obstruction clearance of 1,000’ in non mountainous and 2,000’ in mountainous terrain.
VFR day instrument and equipment required. Acronym
Tomato flames
MOCA
Minimum Obstruction Clearance Altitude. Ensures reliable navigation only within 22 NM of facility and obstacle clearance.
MAA
Maximum Authorized Altitude. Max usable altitude or flight level for an airspace structure or route segment for which adequate reception of navigation aid signals are assured.
MRA
Minimum Reception Altitude. Lowest altitude at which an intersection can be determined.
MCA
Minimum Crossing Altitude. The lowest altitude at certain fixes at which an aircraft must cross when proceeding in the direction of a higher minimum en route IFR altitude.
OROCA (NOS):
Off Route Obstacle Clearance Altitude. Provides obstacle clearance of 1,000 and 2,000’ but may not provide signal coverage from ground based Nav aids, ATC radar, or communications.
MSA:
Minimum Safe/Sector Altitude. Found on approach plates and provides 1000’ terrain clearance within 22NM of the airport, used for emergency purposes.
