For example, the aircraft may have a maximum crosswind component of 15 knots listed in the aircraft flight manual (AFM), and the pilot has experience with 10 knots of direct crosswind. It could be unsafe to exceed a 10 knots crosswind component without additional training. Therefore, the 10 kts crosswind experience level is that pilot’s personal limitation until additional training with a certificated flight instructor (CFI) provides the pilot with additional experience for flying in crosswinds that exceed 10 knots.
One of the most important concepts that safe pilots understand is the difference between what is “legal” in terms of the regulations, and what is “smart” or “safe” in terms of pilot experience and proficiency.
P = Pilot in Command (PIC)
The pilot is one of the risk factors in a flight. The pilot must ask, “Am I ready for this trip?” in terms of experience, currency, physical and emotional condition. The IMSAFE checklist combined with proficiency, recency, and currency provides the answers.
A = Aircraft
What limitations will the aircraft impose upon the trip? Ask the following questions:
• Is this the right aircraft for the flight?
• Am I familiar with and current in this aircraft? Aircraft performance figures and the AFM are based on a brand new aircraft flown by a professional test pilot. Keep that in mind while assessing personal and aircraft performance.
• Is this aircraft equipped for the flight? Instruments? Lights? Navigation and communication equipment adequate?
• Can this aircraft use the runways available for the trip with an adequate margin of safety under the conditions to be flown?
• Can this aircraft carry the planned load?
• Can this aircraft operate at the altitudes needed for the trip?
• Does this aircraft have sufficient fuel capacity, with reserves, for trip legs planned?
• Does the fuel quantity delivered match the fuel quantity ordered?
V = EnVironment
Weather is an major environmental consideration. Earlier it was suggested pilots set their own personal minimums, especially when it comes to weather. As pilots evaluate the weather for a particular flight, they should consider the following:
• What are the current ceiling and visibility? In mountainous terrain, consider having higher minimums for ceiling and visibility, particularly if the terrain is unfamiliar.
• Consider the possibility that the weather may be different than forecast. Have alternative plans, and be ready and willing to divert should an unexpected change occur.
• Consider the winds at the airports being used and the strength of the crosswind component.
• If flying in mountainous terrain, consider whether there are strong winds aloft. Strong winds in mountainous terrain can cause severe turbulence and downdrafts and can be very hazardous for aircraft even when there is no other significant weather.
• Are there any thunderstorms present or forecast?
• If there are clouds, is there any icing, current or forecast? What is the temperature-dew point spread and the current temperature at altitude? Can descent be made safely all along the route?
• If icing conditions are encountered, is the pilot experienced at operating the aircraft’s deicing or anti-icing equipment? Is this equipment in good condition and functional? For what icing conditions is the aircraft rated, if any?
9-7
Evaluation of terrain is another important component of analyzing the flight environment. To avoid terrain and obstacles, especially at night or in low visibility, determine safe altitudes in advance by using the altitudes shown on VFR and IFR charts during preflight planning. Use maximum elevation figures (MEFs) and other easily obtainable data to minimize chances of an inflight collision with terrain or obstacles.
Airport considerations include:
• What lights are available at the destination and alternate airports? VASI/PAPI or ILS glideslope guidance? Is the terminal airport equipped with them? Are they working? Will the pilot need to use the radio to activate the airport lights?
• Check the Notices to Airmen (NOTAMs) for closed runways or airports. Look for runway or beacon lights out, nearby towers, etc.
• Choose the flight route wisely. An engine failure gives the nearby airports (and terrain) supreme importance.
• Are there shorter or obstructed fields at the destination and/or alternate airports?
Airspace considerations include:
• If the trip is over remote areas, are appropriate clothing, water, and survival gear onboard in the event of a forced landing?
• If the trip includes flying over water or unpopulated areas with the chance of losing visual reference to the horizon, the pilot must be current, equipped, and qualified to fly IFR.
• Check the airspace and any temporary flight restriction (TFRs) along the route of flight.
